Why Choose a Whitley Workstation?

There are many reasons to choose a Whitley Workstation when it comes to Anaerobic, Hypoxic or Microaerophilic work. We can discuss these with you anytime, but we also have plenty of satisfied customers who have expressed why using a Whitley Workstation improves their working methods and results.

Over the years, customers have supplied us with many testimonials about their Don Whitley Scientific products. From these we can see that not only have Whitley Workstations become approved by fantastic researchers worldwide, but we can also help promote the amazing work that is done by our customers.

Dr Vaibhao Janbandhu at the Victor Chang Cardiac Research Institute (VCCR) in Sydney, Australia uses a Whitley H35 Hypoxystation in his work on finding new ways to stimulate heart regeneration during ageing and after heart attack. He uses his H35 Hypoxystation to isolate, culture and characterise adult cardiac stem cells. In Dr Janbandhu’s words the H35 is “an integral part of the project to advance the project aims”.

In this video testimonial, Jane Freeman at Leeds General Infirmary explains how her Whitley A95 Workstation improves the working methods in her Clostridium difficile research. Jane reports that she and her team are able to use the workstation for “several hours at a time in relative comfort” and that the workstation is able to house all the technical equipment her team requires. This allows “the whole experiment to be performed in optimum conditions without introducing air at all”. Jane explains that “reliability, versatility and space are the significant benefits of the workstations in our work on Clostridium difficile“.

The Institute of Cancer Research in London is one of the world’s most influential research institutes, with an outstanding record of achievement dating back more than 100 years. At the Institute, George Poulogiannis uses a combination of Whitley i2 Instrument Workstation (with Seahorse XF Analyzer) and Whitley H35 Hypoxystation in his research into breast cancer. Hypoxia is a key factor in the “Hallmarks of Cancer” and this team are studying the role of hypoxia in cell invasion and metastasis, oncogene-induced senescence and resistance to current treatment options. The i2 and H35 replicate a physiologically relevant atmosphere for these studies, enabling consistent and reliable results. This combination of Workstations is also used by Dr Ayse Latif, who is researching gynaecological cancers at The University of Manchester.

Don Whitley Scientific would like to take this opportunity to thank all customers who have provided testimonials. If you would be interested in supplying a testimonial, please contact Alex_Rhodes@dwscientific.co.uk.

Clostridium difficile studies can be done in a Whitley Workstation

Whitley Workstation used in Clostridium difficile study

The Whitley A35 Workstation has recently been used by a group at Monash University in a study relating to toxins affected by Clostridium difficile.

This very interesting research paper, entitled “CdtR Regulates TcdA and TcdB Production in Clostridium difficile“, was written by researchers at Monash University in Melbourne, Australia. The results from the study “establish CdtR as an important virulence regulator in two clinically important, epidemic strains of C. difficile, and further highlights the need to investigate regulatory mechanisms of important virulence factors in diverse strain backgrounds.”  The paper proves for the first time that “TcdA and TcdB production is linked to the production of CDT by a common regulatory mechanism”.

Anaerobes. Where to Start?

Introduction to Clinical Anaerobic Bacteriology

Introduction to Clinical Anaerobic Bacteriology

To a newcomer, the field of anaerobic research can seem intimidatingly vast. With so many varieties of anaerobes, and differing means of culturing them, you may find yourself wondering whether the method you are using is really the most efficient and cost-effective.

The first thing you need to consider is the type of anaerobe you are cultivating, whilst aerotolerant organisms and facultative anaerobes will not be harmed by a small amount of oxygen, obligate anaerobes require a completely oxygen-free environment.

We have recently produced a useful reference guide: An Introduction to Clinical Anaerobic Bacteriology which enables the reader to isolate and identify 12 commonly occurring and clinically important anaerobic bacteria.

Chilled Incubation Compartment

New Chilled Incubation Compartment

If you need to store small quantities of media and samples in anaerobic conditions, but at lower than ambient temperatures, you can now specify an optional Chilled Incubation Compartment for a Whitley A35 or A45 Workstation.

This insulated compartment is located on the left hand side of the workstation and is accessed from the main chamber. When you open the compartment door, the plate carrier basket swings outwards to allow easy access. It has a capacity of 10 x 90mm Petri dishes or items of a similar size.

The temperature in the Chilled Incubation Compartment can be easily adjusted, in 0.1°C increments, via the workstation’s colour touchscreen. The operating temperature range is between +12°C and +25°C and the temperature distribution within the compartment is within 2°C*.

This option must be specified at time of order as it is a factory-fitted modification.

 

*Laboratory and main chamber temperatures may influence the upper and lower temperature levels that can be achieved.

Did you know: How best to clean your workstation?

 

 

This is the 10th in our ‘Did you know’ series of articles introducing things you may not know about the Whitley range of products and services – read on and you may find out something about your workstation that could make your working life easier.

We regularly receive enquiries from customers with regard to which disinfectants can be safely used inside Whitley Workstations. Although it is not practicable to evaluate every available product, we have tested the materials compatibility of several sporicidal disinfectants and can now provide comprehensive advice on this topic.

 

 

How often should I clean my workstation?

DWS recommend that as part of the daily checks, users ensure that the workstation is free from spillage and cleaning carried out as necessary. Prior to having your workstation serviced, however, it may be necessary for it to be decontaminated.

Which disinfectants have DWS tested?

  • Spor-Klenz – peracetic acid (approx 0.1%) + hydrogen peroxide (approx 1.0%) – “ready to use” product, tested without further dilution.
  • Chemgene HLD4H – quaternary ammonium compounds (approx 1%) + chlorhexidine digluconate (approx 1%) – “ready to use” product, tested without further dilution.
  • Safe Hospital – hypochlorous acid – “ready to use” product, tested without further dilution.
  • Tristel Fuse – chlorine dioxide (approx 1%) – prepared from concentrated components according to manufacturer’s instructions.

For more information on these tests, please see the appendices of your Whitley Workstation user manual.

 

Which of the above products are OK for use in a Whitley Workstation?

Our tests demonstrated that each of these formulations is satisfactory for use in Whitley Workstations and will not cause any damage when used in accordance with the manufacturer’s recommendations.

 

What if I want to use a cleaning agent not on the above list?

Other disinfectants containing the active ingredients listed above, at similar concentrations to those shown, can also be safely used inside Whitley Workstations. If you wish to use a disinfectant containing active ingredients not listed here, please contact us for advice before proceeding.

 

Why should I contact DWS for advice – will any damage not be covered under my warranty?

Unfortunately, we cannot cover under the equipment’s warranty any damage caused to a Whitley Workstation as a result of exposure to products that have not been approved by us.

 

Can I use Virkon as my preferred sanitising solution?

After a thorough study lasting 20 weeks, we concluded that the presence of any uncovered containers of Virkon in anaerobic and variable atmosphere workstations leads to the degradation of stainless steel, brass and some other metal components. The effect is more considerable when oxygen is present in the selected gas mixture. These conclusions are supported by technical information available on the Virkon manufacturer’s website and independent observations by an Institute of Materials metallurgist. If Virkon is the preferred sanitising solution these adverse effects can be minimised by ensuring that Virkon within any workstation is always kept in a covered vessel when not in use.

 

OK, so what’s the best way to clean the acrylic parts of a Whitley Workstation?Labdet100 Blog

The transparent and/or white acrylic on the inside and outside of the Whitley Workstation System may be swabbed with a 2% solution of Labdet 100 (DWS – stock code D00003) in warm water and dried afterwards with a soft clean cloth. In the case of culture spillages then any of the disinfectants listed above solution should be applied to the spillage and left for 30 minutes. It should then be mopped.

 

Never use any solvent on the acrylic surfaces of the workstation. Use only water and a mild detergent solution (i.e. Labdet 100 2% solution) as a cleaning agent.

 

What if the spillage leaks underneath the floor of the workstation?

If spillage is not contained on the working surface then access underneath this area will be required in all Whitley Workstations except the DG250. Some workstations require the removal of retaining bolts before the floor can be lifted up or pivoted for cleaning underneath.

If liquid has been spilled upon the Anotox and catalyst sachets they should be removed, dried and/or replaced.

 

How can I deal with scratches on the acrylic plastic surface of my workstation?

Scratches may be removed by gently polishing the surface with ‘DURAGLIT WADDING’ followed by wiping with a soft clean cloth. Deep scratches may require the use of Wet and Dry abrasive paper used wet, followed by polishing with ‘DURAGLIT’ – seek advice from Don Whitley Scientific Limited or our authorised agents overseas.

 

How can I clean the sleeves on my workstation?Sleeve Kit-Components DYK Blog

The white sleeves used on all Whitley Workstations may require cleaning after periods of extended use. There are a number of options for cleaning and some recommendations listed below:

  • Wipe with a mild detergent
  • Wash or dry-clean with a detergent up to 75ºC
  • For disinfection use Sodium Hypochlorite (at no more than 1000ppm active Chlorine) or any of the disinfectants listed above
  • Do not use Biological or Phenolic based cleaners
  • Wash and dry completely before storage
  • Some surface wrinkling may occur.

A research at QUB using the Whitley A45 Workstation

Queens University Belfast

Groundbreaking research conducted at Queen’s University Belfast’s School of Pharmacy and the Centre for Infection and Immunity has led to new knowledge about cystic fibrosis (CF) that is being applied to patient care.

This video, produced by Video Services at QUB, explains new clinical trials where CF patients are participating in a clinical study aimed at bringing medicines and treatments to people faster. An important recent finding was that the lungs of people with CF are host to many different types of bacteria. The team are working to identify which ones may cause problems for people with CF. As part of this identification project, patient samples are processed in the laboratory in anaerobic workstations (the video shows staff using Whitley A35 and A45 Workstations).

The university is also working on better ways of delivering drugs to CF lungs, including the use of nanoparticles.
