Scientifically Based Foam Analysis
Foamability, stability and drainage - with the DFA100 Dynamic Foam Analyser, Krüss has put together an all-round package for foam analysis. Almost anyone wanting to analyse foam production or prevention will find a competent ally in the DFA100.
Volumes from 20ml are foamed with high reproducibility in the column using a gas stream or stirrer. The volumes of foam and liquid are determined continuously and without contact. Thanks to the high sampling rate, the unit even measures very unstable foams.
The software provides characteristics such as decay half-life or values analogue to Ross-Miles in passing, while it determines the transition from pure drainage to decay and the end point of drainage using new patented parameters. The measurement can be parameterised very flexibly.
Space-saving design, rapid column change with easy cleaning, and automatic, statistically evaluated repeat measurements make for the utmost convenience. An option to measure on several columns simultaneously and independently is exceedingly timesaving.

Varifiable, comparable results and procedures require traceable calibrated instruments. The quality of measurements is defined in terms of tolerance and repeatability and is only achievable with the use of calibrated instruments. Huber calibration baths are designed specifically to provide an environment of close temperature uniformity and high stability for calibration applications. The modular concept consists of a combination of calibration bath and a Huber Unistat®
. The Unistat®
controls the temperature within the bath and different Unistats® be matched with different baths for varying temperatures or the volume of the required calibration bath.

Huber calibration baths have the option of a heat exchanger, which can be installed to separate the bath fluid from the circulator fluid. Special calibration software in the circulator and the self-optimising controller with TAC-Technology mean short times between the different calibration temperatures and highly stable conditions at the calibration set point.

CE Mark Conformity For Cryogenic Vials
Wheaton Science Products has announced that its CryoELITE™ Cryogenic Vials are CE marked in accordance with the requirements of Directive 8/79/EC on in vitro diagnostic medical devices. The vials are available from laboratory distributors located throughout the European Economic Area (EEA).
The Wheaton CryoELITE line of polypropylene cryogenic vials is specifically designed for the failsafe cryopreservation of biospecimens for long-term storage and the efficient traceability for future retrieval. To ensure maintenance of sample integrity during low temperature storage and shipping, CryoELITE vials feature a vial and cap configuration that provides more surface contact that
ensures an absolute seal to eliminate leakage that would contaminate the sample. The seal created by the unique manufacturing design exceeds DOT and IATA regulation standards by an average of 35% making them the superior choice for transport of valuable clinical samples as well.

New Launch in the Genetically Modified Cell Market
Sigma Life Science has announced the global release of a pioneering range of engineered mammalian cell lines. This new product range combines Sigma’s proprietary CompoZr zinc finger nuclease (ZFN) technology with the Company’s extensive experience in gene silencing, to offer innovative tools for drug discovery, compound screening and fundamental research applications.
This new range of products includes immortalised cell lines for a broad spectrum of applications, each precisely engineered to help scientists answer specific biological questions. By exploiting the revolutionary genomic editing capabilities of ZFNs, Sigma’s scientists can rapidly manufacture stable cell lines with precise, well-characterised genetic manipulations.
“CompoZr ZFN technology is a significant breakthrough for cell-based research. It enables scientists to generate precisely controlled additions, deletions and modifications to the genome of a living cell,” said Dr Supriya Shivakumar, Global Commercial Marketing Manager for Functional Genomics at Sigma Life Science. “Leveraging this innovative and powerful technology to develop ready-to-use, validated cell lines is part of Sigma’s ongoing commitment to furthering our understanding of biology.”
The programme will use ZFNs to incorporate and develop cell lines with a variety of cellular markers expected to aid in compound screening studies and biochemical pathway analysis, as well as specific isogenic lines designed to advance colorectal and breast cancer research. In addition, Sigma offers a custom cell line engineering service, creating bespoke cell lines to perfectly match a researcher’s application.
