The SFR vario offers online monitoring of oxygen, pH and biomass - simultaneously.
Online measured biomass data can be correlated with parameters like optical density, cell dry weight, or cell concentration. This way it is possible to get real-time information on e. g. OD600 development. The device optics can read out pre-calibrated oxygen and pH sensor spots - integrated in the ready-to-use cultivation vessels - and also comprise a dedicated optical set-up for biomass monitoring. The oxygen uptake rate (OUR) can be calculated from the slope of the online oxygen measurements.
The system has two long-lasting, rechargeable batteries, and is compatible with any standard shaking incubators. Up to 4 SFR vario can be controlled from the SFR vario software. Measurement data is transferred wirelessly via Bluetooth to a PC / notebook.

The new SFR vario is the sole system on the market for simultaneous online measurement of biomass, O2, pH & the oxygen uptake rate (OUR). The application note "New Device for Biomass Monitoring in Shake Flask Culture" shows how your work with microbial cultures will benefit from this new device.
It allows to measure 4 vital parameters in up to 4 shake flasks in parallel. The fact, that O2, OUR, pH and biomass functionality can be purchased separately minimizes your investment to the actual need. It is the combination of functionalities which makes the SFR Vario very interesting for media evaluation as well as process development and optimization ... and all this without sampling.
Please note that for the first couple of months the matching SFS shake flasks will be sold as prototype sensors. Contact Anna to see if this has changed or if you would like more information about the SFR Vario in New Zealand and Australia.
Protos 3 is a revolutionary automated colony counter and chromogenic identification system. Using its sensitive CCD camera and unique lighting coupled with powerful analysis software, Protos 3 counts colonies in seconds and automatically identifies microbial species by their colour on chromogenic plates. This provides accurate, objective and fully traceable results.
The compact Protos 3 attaches via USB to a computer, where microbiologists can input their plate identification and with the one-click colony counting and chromogenic ID software can rapidly analyse a wide range of plate types. The count results can be automatically transferred to Excel where the count, plate ID and images can be saved. This GLP compliant process, with its full audit trail eliminates transcription errors to provide accurate, objective data, which can be reviewed at any time and used to produce professional reports.
Protos 3 can be used with both small and large plates (up to 150mm) to read a range of format types including spiral, pour, spread and dilution series plates. The system’s camera is so sensitive it can routinely detect colonies as small as 43 microns and the unique LED lighting system and Protos 3 software allows analysis of an infinite number of colonies on one plate in seconds, making this an ideal system for use in busy food and environmental microbiology laboratories.

Widely regarded as the best cancer hospital in the USA, The MD Anderson Cancer Centre at the University of Texas currently uses a Whitley H35 Hypoxystation to contribute to their work focused on pancreatic cancer.
Dr. Rafal Zielinski had this to say about their workstation:
“The hypoxia station we have purchased is being used for studies on STAT and HIF oncogenic transcription factors in tumours with major focus on pancreatic cancer. It is well-established that these tumours are highly hypoxic therefore experiments performed in oxygen-limited conditions better recapitulates the natural environment of the cancer, allows better understanding of the physiologic role of STATs and HIFs and enables more accurate evaluation of experimental therapeutic strategies. We also use chronic hypoxia to study metabolism of the cancer cells and to design optimal therapeutic approaches using new inhibitors of glycolysis.”

Lung cancer is the most common cancer diagnosed in the world with an approximate figure of 1.6 million new cases diagnosed in 2008, 80% of which are comprised of non-small-cell lung cancer (NSCLC). Poor prognostic markers and delay in diagnosis account for a large segment of lung cancer cases to be past successful cure. Survival rates for this form of the disease are very low, with a 5-year survival rate of <9% (2010) of cases and <5.3% over 10-years (CRUK, public data). Lipid metabolism has been correlated to malignant progression and poor clinical outcome in NSCLC and has been suggested as a hallmark of cancer proliferation and a discriminating factor in treatment planning.
Dr Rosy Favicchio
Dr Rosy Favicchio, at Imperial College London’s Comprehensive Cancer Imaging Centre, is researching the impact of lipid metabolism in cancer growth and is part of a team developing new diagnostic imaging technology that will help identify cancers based on their metabolic profile.
“We are directing precision medicine strategies by developing new diagnostic, prognostic and predictive biomarkers for patient stratification and early assessment to therapeutic response. If we are to use lipid metabolism as a reporter system for tumour metabolism and synthesize drugs that target the pathways regulating this particular aspect of tumour physiology, we need to generate data that accurately reproduce the tumour microenvironment. The ability to vary the hypoxic load in our model is fundamental for understanding the relationship driving lipid metabolic reprogramming. Our experiments using the Don Whitley Hypoxystation are designed to further our understanding of the role played by lipid metabolism under hypoxic conditions and evaluate its use as an effective biomarker and druggable driver of NSCLC malignant growth”.

PreSens oxygen sensors (like other sensors, e. g. electrodes) measure the partial pressure of oxygen. To get ppm you need the saturation cencentration of the system / solvent the sensor is used in. ppm calculated by the Fibox works for aqueous solutions only, according to:
100 % air saturation is 9 mg / 1000 g H2O (298 K) and 1 atm, i. e. 9 ppm
If the solubility of oxygen in the solvent is considerably higher than in water, ppm at saturation in higher.
Do you have any other questions? Feel free to contact Anna.

Following the success of the HypoxiaNet meeting in Essen last year, Don Whitley Scientific will be attending the next event – 8 to 12 June 2013 – in Oulu, Finland. With a host of international speakers lined up, the subject of this year’s meeting is ‘Dealing with hypoxia: regulatory aspects in cells, tissues and organisms‘ -
“Hypoxia can be life threatening – for cells and the organism. To adequately respond to the shortage of oxygen cells have to sense changes in their ambient oxygen concentration. How are changes in a physical parameter, i.e. the pO2, translated into a biological response such as modulation of gene expression?”
The aim of the meeting is to highlight and discuss the latest developments in the broad field of hypoxia response. This is the second international congress arranged by the network following the Oxygen 2011 meeting in Davos, Switzerland.
The program of the 2013 meeting will include keynote lectures, short talks selected from submitted abstracts and a training school session.
Don Whitley Scientific will have a Hypoxystation at the meeting and our representatives: Fergus Murray (Product Engineering Manager), Sally Shelton (Export Manager) and Alun Kitsell (Export Sales) will be on hand to answer questions about the workstation.
For further details on the meeting or to book a place, please visit the event website.
Don Whitley Scientific (DWS) invites New Zealand customers to attend a workshop on Campylobacter ‘Omics technologies and their role in food safety’ in Hotel Monaco, Denver, Colorado (USA). The event will be run by Campylobacter, Helicobacter and Related Organisms (CHRO) on the 19th of May, 2013.
Later this year, DWS will be attending the second workshop organised by the CHRO which is to be held in the UK 15-19 September. If you will be attending please be sure to say hello to DWS colleagues Dr Andrew Pridmore and Joe Walton.
