Anaerobic Workstations; Why Bigger is Better!

Anaerobic workstations offer precise and reliable atmospheric control, more stringent anaerobic conditions and consistently low running costs. One of their greatest advantages is that culture plates can be inspected at any time without disturbing the incubation conditions. In clinical laboratories, this has been proven to increase the isolation rate of anaerobic pathogens and also provide the earliest possible indication of their presence in a patient’s sample.

Don Whitley Scientific has excelled in meeting the needs of microbiologists for over 40 years, and as our customers’ needs have evolved, so too have our products. The unique Whitley Internal HEPA Filtration System is an extremely attractive feature, particularly when used in conjunction with research applications as it ensures that all of the atmosphere inside the workstation is passed through the filter hundreds of times an hour.

Over the past few years, an increased demand for using microscopes and other instruments such as the Workstation WASP Touch under anaerobic conditions resulted in the introduction of the A135 HEPA (pictured below); currently our tallest, widest, deepest workstation with a huge internal volume of 560L. The A135 is fitted with a removable front to facilitate thorough cleaning, easy replacement of the HEPA filter, and the transfer of bulk samples and larger pieces of equipment for use in the workstation. Other features include a built-in rapid airlock, integrated gas control and automatic commissioning cycle. To read the full specification and see the extensive list of factory-fitted options, please click here.

KU Leuven in Belgium were one of the first customers to purchase an A135 HEPA, and we asked them to describe the work they are doing and how this workstation has benefited their research:

A135 HEPA

“One of the key research activities in the Raes lab involves the isolation and culturing of gut anaerobes to study their metabolic and genomic properties and, ultimately, to unlock their biotherapeutic potential in human health and disease. In order to scale up these isolation efforts, we aim to move beyond conventional approaches based on agar plating and explore the application potential of novel, miniaturized, and high-throughput technologies. For testing a recently developed millifluidics-based single-cell sorting device, we soon realized that the operational space in our current DWS A35 HEPA anaerobic workstation would be insufficient. Therefore, we brought together product specialists from millifluidics and DWS to constructively discuss technical details on required dimensions, operator access, power supply, connection to an external PC, possible interference of the workstation’s pressure and the device’s heat output as well as safety aspects. This guided us towards the purchase of the DWS A135 HEPA, which is probably one of the best options currently on the market for the anaerobic integration of medium-sized pressure-controlled devices while still offering sufficient operator space and incubation volume.”

– Geert Huys, Department of Microbiology & Immunology, Rega Institute, KU Leuven & VIB Center for Microbiology, Leuven, Belgium

For one of our UK customers, however, 560L was still not big enough. They approached us in early 2018 and asked if we could build something even bigger! Always keen to rise to a challenge… Don Whitley Scientific is pleased to announce that in early 2019 we will release the first A155 HEPA Anaerobic Workstation. This exciting new product will offer all the same advantages as the A135, but with the added benefit of over 1000L of capacity. More information on the A155 will be made available in due course.

Distributor Meeting Held at New Factory

Last week, DWS welcomed 38 representatives from over 20 different countries for the first International Distributor Meeting to be held at our new factory in Bingley. On the first night we held a welcome dinner, and as part of the evening there was a presentation to four of our distributors who had excelled in certain areas. Our special thanks and congratulations to VWR (Sweden), Lab Technologies (India), Cold Spring Biotech Corp (Taiwan) and Hua Yue Enterprise Holdings Ltd (China). Another award should go to our colleagues from AS1 Limited in New Zealand, who travelled over 11,000 miles to be with us!

It was a busy few days packed with sales and installation training on the WASP Touch and our hypoxic, anaerobic and microaerobic workstations. The meeting provided an invaluable opportunity for the distributors to get hands-on experience with our whole product range and to receive training from the people who design and build our equipment on a daily basis. One of the attendees commented: “Our thanks to you and all your colleagues for a brilliant couple of days and a superbly structured meeting which I’m sure will be very fruitful.”

As with our past meetings, we felt it was important to balance out the hard work with some fun and offer our guests a chance to socialise after the training sessions. Our evening entertainment included lots of delicious food and activities such as bowling, cheese-tasting, a magic show (courtesy of our wonderfully multi-talented sales rep, Stuart) and a musical performance from a local brass band.

Distributors_Oct18_Group PhotoWe are very grateful to the distributors who took time out of their busy schedules to attend, and for all of their hard work during the week. We hope everyone enjoyed it as much as we did and look forward to our next meeting!

Calibrating a Workstation to UKAS standards

UKAS Calibration and Temperature Uniformity in Whitley Workstations

ISO 15189:2012 Medical Laboratories- Requirements for Quality and Competence requires medical laboratories to have documented procedures for the calibration of equipment that directly or indirectly affects examination results. Equipment calibration is also beneficial for laboratories  without specific accreditation. For example in research institutions it demonstrates compliance with internationally recognised quality standards and increases confidence in test results. This principle is particularly applicable to temperature controlled equipment, such as incubators and anaerobic workstations, which may be used during the isolation, enumeration or identification of bacteria.

Benefits

The benefits of temperature calibration, and temperature homogeneity throughout the working volume of an appliance, are well understood for conventional incubators because variability in performance can affect the numbers, sizes and other visual characteristics of bacterial colonies growing on agar plates, as well as bacterial growth rates in liquid culture. Microbiologists are also beginning to appreciate the influence of temperature and other environmental parameters on the growth and viability of anaerobic bacteria.

Fastidious Anaerobes

An increasing number of our customers use anaerobic workstations to grow highly fastidious, poorly characterized anaerobes, which have been identified in complex ecosystems using molecular techniques but, until recently, have not been cultured. For example, there is considerable current interest in the bacterial species which constitute the normal human gut microbiota and the role of these organisms in human health. The growth requirements for many of these species are not yet fully understood. Ensuring temperature stability and homogeneity throughout the working area of an anaerobic chamber provides an additional level of assurance when working with fastidious anaerobes and removes a potential variable when attempting to optimize their growth and study their physiology.

Temperature Mapping

If your laboratory must demonstrate that temperature performance could directly or indirectly affect results, the temperature mapping process provides independent, UKAS-accredited testing and supporting certification. It confirms that the workstation temperature is controlled and displayed within specified tolerances. This process comprises calibration of the workstation temperature sensor and a comprehensive temperature profile of the entire working and incubation area. Data is collected from up to 12 sensors, traceable to national standards, positioned throughout the workstation chamber.

How we achieve a uniform temperature gradient in Whitley Workstations?

This is achieved through careful design of the product, optimising air flow and temperature control to achieve the lowest possible temperature gradient. Don Whitley Scientific has been designing and manufacturing modified atmosphere workstations for over 40 years so have a wealth of experience in this area.

DWS UKAS Service

In order to save you the cost of expensive call outs and project delays, we can often provide essential maintenance, schedule routine servicing and carry out your UKAS calibration/ validation work in the same visit. Whilst onsite, our engineers will not only take the time to explain the calibration procedure and why it is necessary but they will endeavour to provide your certification within 5 working days. This helps to make sure the whole UKAS process is as painless as possible for you and your staff.

Even if your laboratory doesn’t necessarily need UKAS accreditation, the cost is comparable with that of standard calibration. This means that for added peace of mind, UKAS calibration/validation could be a very shrewd investment. And because we can carry out any repairs or servicing at the same time, this can help avoid the cost of additional call outs and reduce down-time in your laboratory.

The technical expertise employed within Don Whitley Scientific for designing and manufacturing our own microbiology equipment provides an ideal background for our UKAS-approved calibration engineers.

Your queries answered – no obligation

If you have any additional questions about UKAS or would like any additional information about the benefits that this service could bring to your laboratory, please contact us today for a no-obligation consultation.

Whitley A95 Workstation for Jin Sung on final test

End of an Era for Don Whitley Scientific

Production comes to a close in Shipley

The last Whitley Workstation to be manufactured by Don Whitley Scientific in Shipley has now rolled off the production line. This particular order was an A95 Anaerobic Workstation ordered by Jin Sung Unitech, Republic of Korea.

JS Unitech LogoAccording to Junghoon Hong of Jin Sung, “We had no idea that in placing this order, we would be commissioning the last ever workstation to be built at Don Whitley Scientific in Shipley. We have been distributing Whitley Workstations for 19 years and are very proud to have ordered the last one from the Shipley production line.”

Paul Walton added, “I am extremely happy that we are moving to bigger and better premises that will provide the opportunity to improve our production processes. Victoria Works will provide considerably more warehousing capacity plus new offices, a bespoke production area, service centre, R&D mezzanine and improved staff facilities including a large, fully fitted, air-conditioned canteen. There will also be a new product showroom where customers can view demonstrations of the latest anaerobic and hypoxic workstation technology.

“An element of nostalgia is, however, creeping in as we draw close to the move date. We have been manufacturing in  Shipley for over 40 years and I have seen many changes in those four decades. We will, however, focus on the positives and move the business forward to face the challenges of the next 40 years!”

When Don Whitley Scientific began making workstations, it was purely for the UK market. We now have over 4,000 workstations in over 50 countries.

It might be the end of one era but another, exciting one begins at our new premises in Bingley.

Rest Assured That Your Anaerobic Workstation is at Zero Oxygen

The following was written by Microbiology International, Don Whitley Scientific’s supplier of the Anaerobic Workstation in the US

Don Whitley Scientific have turned the maintenance and monitoring of stringent anaerobes in their anaerobic workstations into an art. The unique combination of anaerobic conditions monitoring (ACM) and catalyst monitoring available on the  A35, A45, A55, A85 and A95 workstations guarantees that strict anaerobes really will be well within their comfort zone. Microbiology International is the North American distributor for these anaerobic workstations.

The ACM comprises of an oxygen sensor placed inside the workstation and software to process real-time data on oxygen levels in the chamber. Based on knowledge of bacterial oxygen tolerance, results are shown on the touchscreen interface as a colour-coded indicator of O2 concentration. Green, yellow, or red status bars clearly indicate to the user whether oxygen levels are acceptable and provide information on the correct functioning of the workstation. This fully automated system replaces resazurin strips, which can dry out and are subject to interpretation based on the pink-to-white colour change.

The palladium catalyst used to remove traces of oxygen in the Don Whitley Scientific anaerobic workstations is protected through the addition of Anotox, which removes volatile organic compounds and hydrogen sulfide from the chamber atmosphere. Proper functioning of this vital system is monitored by the patented Catalyst Monitoring System, which tests the function of the catalyst overnight, and also confirms that the necessary hydrogen is present.

Together, the anaerobic conditions and catalyst monitoring systems provide unambiguous proof that anaerobiosis is being maintained in the workstations. The art of “zero oxygen” is critically important to cultivating anaerobic microorganisms that, due to their fastidious nature, are often classified as “unculturable“. Taking advantage of the closed workstation format to establish a strictly controlled anaerobic atmosphere, researchers are using Whitley Workstations to examine diverse topics such as the degradation of complex glycans by human gut microbiota;  the rise in C. difficile infections through lawn contamination; and the anaerobic etiology of brain abscesses.

The A35 Anaerobic Workstation will be on the Don Whitley Scientific stand at this years IBMS Congress in Birmingham
