Operational Flexibility of M Series Workstations

Whitley Microaerobic Workstations from Don Whitley Scientific are designed to allow users to control oxygen, carbon dioxide and hydrogen within safe working limits.
By using sophisticated sensors, actual gas levels can be monitored on the touchscreen, giving the user confidence that their samples are being incubated for the appropriate atmosphere.

M series workstations create accurate and reproducible conditions within safe operating parameters. They provide the most flexibility of any models in the Don Whitley Scientific range as they allow Anoxic/Anaerobic, Microaerobic or Hypoxic atmospheres to be created if desired.

 

Microbiological Applications:
• Anaerobic atmosphere: An oxygen free atmosphere.
• Microaerobic atmosphere: An atmosphere suitable for growing organisms that require oxygen levels lower than those found in air. Hydrogen can be included in the atmosphere if required.

Cell/Tissue Culture Applications:
• Hypoxic atmosphere: An atmosphere suitable for growing cells under physiologically relevant conditions, containing oxygen levels of between 0.1% and 20%, along with carbon dioxide at the required concentration (up to 15%).



Microaerobic operation using an M series workstation
For standard operation of Whitley Microaerobic Workstations, four separate gas cylinders of carbon dioxide, oxygen free nitrogen, compressed air and a 10% hydrogen/90% nitrogen mix, need to be connected to the workstation. This allows the user to select a safe workstation atmosphere from the following available ranges:

Oxygen 0 – 20%
Carbon Dioxide 0 – 15%
Hydrogen 0 – 5%
Nitrogen Balance

Hypoxic operation using an M series workstation
For hypoxic operation only carbon dioxide, oxygen free nitrogen and compressed air should be connected to the workstation. As hydrogen is not required no gas needs to be connected to the 10% hydrogen/90% nitrogen gas input. This will allow the user to choose from the following:

Oxygen 0 – 20%
Carbon Dioxide 0 – 15%
Nitrogen Balance

 

Anoxic/anaerobic operation using an M series workstation
The M Series can be operated anaerobically (Anoxic conditions) by introducing a catalyst. Any oxygen then present in the workstation atmosphere combines with hydrogen to create water. The catalyst facilitates this reaction and any excess water condenses on a chilled plate and is automatically removed from the workstation.

WASPLab

New Segregation Software a Success for Leeds WASPLab

For several years, Don Whitley Scientific have been installing WASP and WASPLab units in locations around the UK. Locations that include Leeds General Infirmary, PHE Public Health Laboratory in Manchester and Blackburn Royal Hospital. Though the set-up and configuration of the systems differ (due to the modularity of WASP and WASPLab), all installations have provided an increase in efficiency and productivity in routine microbiology work. The WASPLab laboratory at Leeds have recently started using new segregation software, offering increased efficiency.

WASPLab is the sophisticated, barcode-driven, microbiology specimen processor and work-up system, moving samples from front end processing to full specimen management, automated incubation and digital microbiology. It has been long thought that bacteriology was the last bastion of traditional manual techniques but the way in which plates are read and interpreted changes dramatically with the use of WASP and WASPLab.

 

New Segregation Software

The WASPLab at Leeds General Infirmary was the first WASPLab Don Whitley Scientific and manufacturer Copan installed in the UK. The WASPLab at Leeds is one of the largest configurations of the system in the UK and they continue to make further improvements, such as new segregation software to separate negative MRSA results from the positive samples (Blackburn Royal Hospital will also be processing MRSA samples). The impressive software allows the laboratory worker to report 300 negative samples within a minute and a half, offering incredible levels of efficiency.

Copan continue to provide automated solutions for laboratories around the world. Don Whitley Scientific are proud to work with Copan, installing WASP and WASPLab systems in the UK.

Clostridium difficile studies can be done in a Whitley Workstation

Hypoxic Snapshot Analysis in a 3D Engineered Tumour Scaffold

Researchers have long exposed 2 dimensional cells to varying degrees of hypoxia, often found in the tumour microenvironment. This can be great for showing overall hypoxic protein expression, but fails to account for cell to cell interactions, tissue gradients, and metabolic reprogramming. To more closely mimic in vivo conditions, a 3D culture environment is necessary. While 3D culture is nothing new, Rodenhizer et al in their paper “A three-dimensional engineered tumour for spatial snapshot analysis of cell metabolism and phenotype in hypoxic gradients” found a novel way to culture in a 3D environment while maintaining the ability to perform analyses that only function in 2D. These ingenious authors did all of this in their Hypoxystation by Don Whitley Scientific. They were able to analyse and map cellular metabolism and spatially identify known and novel metabolic response to hypoxia.

The team took carcinoma cells and seeded them onto a novel rolled scaffold system the authors termed “TRACER”. They exposed the scaffold to varying degrees of hypoxia, down to as low as 0.2% O2. After incubation they unrolled the 3D scaffold and started analysis to create a metabolic snapshot of the tumour. They found the 3D scaffold tumours displayed different concentrations of metabolites as compared to 2D tumour cells, implying cell to cell interactions plays a role in tumour metabolism, depending on the depth of the cell in the scaffold. The future of cancer research will be shaped by this innovative technique and oxygen control plays an important role with use of the Hypoxystation.

The Don Whitley Scientific Hypoxystation is ideal for many applications, as it can control oxygen down to 0.1% while providing a temperature and humidity controlled environment with ample working space. ISO class 3 clean room HEPA filtration is also available for long term cell culture applications.

Professor Tom Riley Lab

30 Year Commitment for Professor Tom Riley

Professor Tom Riley from Pathwest Laboratory Medicine and The University of Western Australia has been a committed Don Whitley Scientific customer for over 30 years. In the past few years he has installed two A35 Anaerobic Workstations into his lab to replace a Whitley MK III Workstation that had given him over 20 years of reliable performance.

Professor Riley started using anaerobic workstations over 30 years ago when the capacity and time consuming operation of jar gassing systems was deemed unsuitable for the number of samples he had. Tom explained to Don Whitley Scientific how he came to use Whitley Workstations. “My original anaerobic chamber from a manufacturer in Australia (that doesn’t exist anymore) was hopeless.”. The next option for Professor Riley was a Whitley MKIII Anaerobic Workstation, which served his lab for over 20 years, and was the first Whitley Anaerobic Workstation in Australia. His two Whitley A35 Anaerobic Workstations currently play a part in work that Professor Riley explains as “almost exclusively research into Clostridium difficile. This includes everything from diagnostics to pathogenesis and epidemiology”.

Although the MK III provided a reliable anaerobic environment for such a long time in Professor Riley’s lab, there are new benefits provided by the A35 Anaerobic Workstation that Tom finds particularly useful, such as the Instant Access Porthole System and Letterbox entry. The Instant Access Porthole System is unique to DWS, allowing entry to the chamber in seconds without the need of gloves or sleeves. Letterbox entry allows the user to introduce Petri dishes and similar small items into the anaerobic workstation environment in no time at all. As aforementioned, Tom also needed extra capacity to process a large number of samples. Compared to using the MKIII or anaerobic jars, the main chamber of an A35 Anaerobic Workstation will accommodate between 400-600 x 90mm Petri dishes depending on whether plate carriers are used, which accessories and system options have been incorporated and how much working space is required.

The space and reliability provided by Whitley Workstations has served Professor Tom Riley well for over three decades now. He is part of a long list of satisfied Whitley Workstation users around the world, who are all doing fantastic work with Don Whitley Scientific products.

Yorkshire Air Ambulance – Chosen Charity for 2018

Each year, Don Whitley Scientific staff choose a charity to donate funds to during the calendar year. After holding a vote involving many different charities, the majority of DWS staff voted for Yorkshire Air Ambulance for our 2018 charity. Yorkshire Air Ambulance was established in 2000 and has developed into a sophisticated emergency service that provides state-of-the-art emergency medical care throughout Yorkshire. Yorkshire has a vast topography that not only includes remote, rural and densely populated areas but also includes major motorways and road networks such as the M62, M1, A1 and M18. Don Whitley Scientific was established in West Yorkshire, making this a fitting choice for this year’s charity.

In 2017 Don Whitley Scientific donated funds for a girl named Isabelle Barnett, who suffers from Rett syndrome, a rare genetic neurological and developmental disorder that affects the way the brain develops, causing a progressive inability to use muscles for eye and body movements and speech. We managed to raise £3,806 which according to Isabelle’s parents, should enable the purchase of a special ‘goto’ seat, a chair for the bath and a standing frame. All staff worked hard at raising funds by supporting cake sales, staff lunches, various seasonal raffles and supplying fantastic recipes for a Cookery book which sold extremely well. Many of our suppliers were also extremely generous in donating great prizes for our big Christmas Raffle.
