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.
AS1 shares a webinar of Dr. Robert Meier showing us how to gain new insights on metabolic activity, natural or artificially produced gradients, detect metabolic hotspots, record time-series, monitor hypoxia, cellular growth or oxygen supply inside the chip with VisiSens.
Read MoreThe focus of this years conference was the challenge of being a scientist in the post-genomic era. The conference presentations discussed the challenge of functional genomics, New Zealand’s biological heritage and science for technological innovation.
AS1 display visitors were particularly interested in Biolog, DWS Anaerobic and Hypoxia cabinets, and Presens oxygen monitoring systems
It was an excellent meeting with a lot of interesting presentations and posters.
For more information about the event or a product, please Contact Anna.
Presens answers Frequently Asked Questions include how to test the stability of a sensor of an organic solvent and how to incorporate an optical DO sensor into a minibioreactor with an 8mm or a 6mm fitting.

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.

Today we have the pleasure to introduce to you our brand new Microx 4 & Microx 4 trace! For the time being, it is the sole independent display controlled device on the market handling non-invasive and microsensors as well as sensor probes. Together with this stand-alone, portable fiber optic oxygen meters we present you two new sensor types: PSt7 for measurements in normal oxygen range (detection limit 15 ppb, 0 - 100 % oxygen) and PSt8 (detection limit 3 ppb, 0 - 10 % oxygen) for measuring oxygen traces.
PreSens will present the devices for the first time at the Analytica in Munich, April 1st - April 4th, 2014. The official start for sale will be on May 5th, 2014. But we will surely accept your orders beforehand.
Additionally, please note that we harmonized two of the technical specifications for hydroplates and hydrodishes. By next week we will also present new single-use flow through cells for oxygen and pH to our customers.

AS1 is pleased to announce, Dr. Barry Bochner will be presenting in New Zealand. Read his Biography and Presenting Schedule and contact Anna if you are interested in attending.
TITLE: Phenotype MicroArrays: An Overview of the Technology and Applications
PRESENTER: Barry R. Bochner, Ph.D., CEO & CSO, Biolog, Inc., Hayward, CA Biography and New Zealand Presenting Schedule
Phenotype MicroArray (PM) technology allows a biologist to test thousands of phenotypes of a cell line in a single experiment, to gain a comprehensive overview of the metabolism, physiology, and pathway fluxes.It provides phenomic and metabolomic information that is complementary to genomic or proteomic analysis and often more easy to interpret and more useful.The PM technology platform is applicable to a wide range of cells including bacterial, fungal, or animal and enables metabolic analysis in the context of genotype-phenotype studies. For example, it can be used for (1) analyzing cells with mutations to determine the metabolic and physiologic effects of genetic differences, (2) studying and defining cell metabolism and metabolic regulation, (3) understanding the interplay of environment and hormonal signals on cell metabolism and physiology, (4) optimizing cell culture conditions, and (5) looking at the effects of drugs and other chemicals on cellular pathways. For microbial cells, recent work has demonstrated the utility of the technology for determining culture conditions that turn on and turn off production of toxins and other secondary metabolites that microbes can produce. The technology also has many applications with human cells, including the assay of the effects of microbial toxins. Specific examples and discoveries will be presented to illustrate the many uses of PM technology.
