Don Whitley Scientific in Spain

The Don Whitley Scientific demonstration truck is currently making its way through sunny Spain! Accompanied by our sales team, the truck is visiting various research and clinical institutes throughout the country to discuss how DWS equipment may enhance and benefit a range of scientific applications.

The demonstration vehicle is becoming an increasingly useful resource, enabling DWS to visit customers around the continent to demonstrate a wide range of equipment. The truck has previously been to Europe (Poland, Czech Republic, Hungary and Austria) as well as sites across the UK and is now visiting existing customers and distributors, as well as potential new customers, in Spain.

Last week saw the trip begin, with Joe Walton and Sally Shelton setting off from Portsmouth on a ferry to Bilbao. The first destination was Pamplona, where Joe and Sally met up with Sandra Berges from our Spanish distributor, Nirco, to visit existing and potential customers in the area. The truck provided Sally and Joe with the ability to demonstrate products and have an area to  discuss any potential sales with our customers. It also allows us to obtain customer feedback on how our equipment works in their lab, in this case a Whitley H35 Hypoxystation, which the customers were actually very happy with.

The next day involved a long seven and a half hour drive to Barcelona. Once in the capital, the team visited a hospital to see current customers who are using Whitley products in various research based applications. Next stop was the research building at another  hospital in the area where visitors to the truck displayed a clear interest in the Whitley Hypoxic Workstation.

The last day of this part of the road trip involved visiting some existing customers at a research centre in Barcelona, their research involves Treponema denticola and Tannerella fosythia, which need strict anaerobic conditions to grow. The researchers at this institution have been using Don Whitley Scientific equipment for 20 years and discussed replacing one of the older models they had with one from the more modern Whitley Workstation range.

We would like to say a big thanks to Sandra from Nirco as the trip was a very worthwhile experience.

Liverpool Lab Highlights Significance of Hypoxia in Glioblastoma Research

Studies into the effects of hypoxia on different areas of glioblastoma were recently published by a lab at the University of Liverpool. Violaine See’s lab investigated the effect of both cell cycle progression and specific chemical signatures under varying levels of hypoxia. In both instances, the physiologically relevant environments created by Whitley H35 Hypoxystations can be considered an integral factor in ensuring the results were dependable and accurate.

The first paper, entitled “Cell cycle progression in glioblastoma cells is unaffected by pathophysiological levels of hypoxia” highlights the effects of Hypoxia on glioblastoma (brain tumour) cells. Specifically, the aim of the study was to investigate how varying oxygen levels can effect cell proliferation and survival in glioblastoma.  The results explain how solid tumours can be both hypoxic and highly proliferative and reinforce the importance of using the correct physiologically relevant oxygen tensions when investigating tumour hypoxia.

The second paper, “Use of infra-red microspectroscopy to elucidate a specific chemical signature associated with hypoxia levels found in glioblastoma” also looks at the effect differing oxygen levels can have on glioblastoma. Studying the metabolic changes that occur in tumours which are triggered by hypoxia, the paper describes the role these low oxygen levels play in the development and aggressiveness of the tumour microenvironment.

In both of these studies, the cells were cultured and incubated in a Whitley H35 Hypoxystation at a level of 1% oxygen. The H35 Hypoxystation is an ideal hypoxic cabinet for ensuring a stable, physiologically relevant atmosphere for cell cultures. Features like data logging make sure conditions can be monitored over a long period of time and the Hypoxystation is fitted with an oxygen sensor to make sure a consistent atmosphere is maintained within the cabinet.

This is not the first time Violaine See has mentioned the use of the Whitley Hypoxystation in her lab. She has provided a video testimonial for Don Whitley Scientific as someone who is happy with her workstation and the level of service provided.

Don Whitley Scientific attend Analytica 2016

Don Whitley Scientific and subsidiary Meintrup DWS Laborgeräte joined forces at this year’s Analytica 2016 in Munich, Germany, to launch the new Whitley WASP Touch spiral plater.

Analytica is one of the largest international trade fairs for the laboratory technology, analysis and biotechnology industries. In addition to this there is also an international conference that brings together suppliers, users and researchers. This conference encourages collaboration of the highest standard between people from scientific institutions around the world.

Visitors to the Don Whitley Scientific stand were among the first to see WASP Touch. This spiral plater has been designed for the needs of modern microbiology labs. WASP Touch is a fundamentally different plater with no need for a separate vacuum source. The system is extremely simple to use, provides real cost savings and process improvements, and eliminates serial dilutions. As well as providing Automated Intelligent Monitoring Software (AIMS) to guide you through set-up and daily check routines – to ensure consistent trouble-free plating – the device features:

  • Touchscreen operation
  • New automatic sanitising system automatically maintains correct liquid levels in sanitising solutions – patent pending
  • Illuminated, covered working area
  • Robust and reliable
  • Easy serviceability.

Sales representatives from our Brazilian distributor, Marconi, were given the first demonstration of the new system.

Once again, Analytica has proven to be a fantastic opportunity for Don Whitley Scientific to meet potential new customers and touch base with our existing distributor network.

Automated Intelligent Monitoring Software (AIMS) guides users through set-up and daily check routines to ensure consistent, trouble-free plating. Sample may be aspirated from beakers, bottles and tubes – providing maximum flexibility in use.

The system incorporates a powerful diagnostic tool that automatically logs date, time, deposition, user name and number of plates produced.

Precise quantities of sanitising fluids are dispensed automatically to maintain optimum levels. This ensures effective and efficient sanitisation takes place. Sanitising system reservoirs contain sufficient fluid for over 900 wash cycles.

A space-saving feature is the fully integrated vacuum waste system.

Robust, reliable and easy to service, WASP Touch eliminates serial dilutions and produces perfect plates.

Professor Patrick Frost from UCLA speaks to HypOxygen

Patrick Frost, a professor at UCLA recently spoke to our US distributor, HypOxygen, about his work and how it is benefitted by the use of a Whitley H35 Hypoxystation. Professor Frost is investigating how the adaptive hypoxic response in mutiple myeloma cells affects tumor progression, hoping to provide insight into the pathology and chemotherapy resistance of this incurable disease.

Patrick Frost has been using the Whitley H35 Hypoxystation for almost 3 years now, and he does not miss bygone days in the lab: “We started out with just a Plexiglas box, with some valves in it, with a front cover just held on magnetically, placed inside an incubator. We would burn through a 50 L tank of nitrogen in 48 hours. I was never convinced that we had the correct level of oxygen in there”.

Now, despite two groups using the H35 intensely at 0.2 % oxygen, that gas bottle can easily last a month. Dr. Frost says, “If we shut the workstation down, the atmosphere stays stable, we don’t lose the hypoxia. It’s been a year since we replaced the CO2 bottle, and the compressed air.” Don Whitley Scientific has conducted gas consumption studies that show the Whitley H35 Hypoxystation “at rest” uses only 3.5 L of nitrogen gas/24 hour period, 47 and 28 times less than other hypoxia workstations. Part of the reason for the stability of that atmosphere is the annealed, thick acrylic build of the Hypoxystation. Dr. Frost states, “It’s pretty robust, it’s survived a move and a forklift and it never sprung a leak throughout. “
