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.

The Mould That Changed the World

Don Whitley Scientific has some very talented customers, not least Leeds Biomedical Scientist, Helen Inns. Helen is usually to be found at the WASPLab, working with bacteria including MRSA and Carbapenemase-Producing Enterobacteriaceae. This month, instead of just looking for “Superbugs”, she’s making a song and dance about them – at the Edinburgh Fringe in a show called The Mould That Changed The World.

Helen is part of a chorus of healthcare professionals performing in the world premiere of a brand-new musical, called The Mould That Changed the World. The show is a fun educational production which tells the story of Fleming’s discovery of penicillin, the development of antibiotics, and the looming crisis of antimicrobial resistance which now threatens healthcare as we know it.

Banner ad for The Mould that Changed the World

The Mould That Changed the World is receiving rave reviews at the Edinburgh Fringe, where it’s showing daily until 25th August.

After that, a free resource pack will be available, so primary schools can put on their own production and empower children to learn about and spread the message of antimicrobial stewardship.

PaCMAn Course Photo

Successful PaCMAn Course 2018

Another successful Practical and Clinical Microbiology of Anaerobes course was held on 14 & 15 June in Cardiff. We had a full complement of 26 delegates, including overseas visitors from Ireland, Norway, Sweden, Romania, Germany and Costa Rica.

This 2-day residential course enables delegates to refresh their knowledge on culturing, identification and the clinical importance of anaerobes and allows them to learn from clinical and laboratory professionals about the latest technologies and techniques. The course is delivered by the UK Anaerobe Reference Unit, Public Health Wales, Cardiff and is CPD accreditated by RCPath (11 credits).

 

The main aims of the course are:

·         To promote an understanding and awareness of anaerobic bacteria in clinical material.

·         To gain an insight into their relevance in clinical microbiology.

·         To achieve a basic level of competence in methods used for their isolation and identification.

·         To improve the standards of anaerobic microbiology in clinical laboratories.

 

Feedback from delegates has again been very positive with the majority rating it ‘excellent’ overall. Participants particularly enjoyed the friendly and informative course atmosphere and provided comments such as:

“Excellent course will definitely recommend to others.”

“Will be recommending for colleagues to attend.”

“Engaging speakers, very helpful, great team. I would highly recommend this course. I have learnt so much and look forward to passing all this great information to my team at work.”

“A fantastic course that came highly recommended to me and I will certainly
recommend to others.”

“It is an excellent workshop and I will recommend the course, even if you are working outside of the UK. Lectures were clear and well organized. The booklets are very educational for my needs.”

 

Whitley A55 WorkstationDon Whitley Scientific sponsors and helps to administer the course on behalf of the UK Anaerobe Reference Unit (ARU). We loaned the ARU a Whitley A55 Workstation for the course so that they had increased incubation capacity for the practical sessions.

It is planned to hold the course again in 2019 but dates have not yet been finalised. Keep an eye on the DWS blog or contact us on sales@dwscientific.co.uk if you are interested in attending this event.

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.
