Model and Method for Optimal Sizing of Serial Microfiltration Systems

dsDNA-Specific Nucleic Acid Quantitation Reagent
Promega Corporation has announced the launch of the QuantiFluor® ONE dsDNA System, a sensitive, double-stranded (ds) DNA-specific fluorescent dye suitable for use in research and clinical workflows. The new dye system is integrated into the new Promega Quantus™ Fluorometer and GloMax® detection instruments, but is compatible with any fluorometer capable of measuring the appropriate fluorescence excitation and emission spectra.

The QuantiFluor ONE dsDNA System is supplied in “add-and-read” format, enabling users to simply quantitate even low-concentration samples with confidence, and without dilutions or additional tubes. The dye system has significantly increased sensitivity compared to absorbance-based systems and is highly specific to dsDNA, showing minimal binding to single-stranded DNA, RNA, protein, and interfering compounds.

Safe Storage of Vaporous Lab Chemicals
The new Safestore™ vented chemical storage cabinet from Air Science™ is ideal for the storage of noxious or odorous chemicals. These cabinets minimize health and environmental risks in handling chemical vapors and residues, volatile organic compounds (VOCs), and general laboratory functions. They are available in three capacities, 25, 1,000, and 2,000 liters.

Incorporated into the Safestore is the Air Science Multiplex™ filtration system, which protects the safety of personnel during use, maintenance, and decontamination. Advanced carbon filtration technology offers a safe and high-performance alternative to ducted cabinets for a broad range of applications. Safestore cabinets isolate and trap biological and chemical vapors to prevent operator exposure, cross-contamination, and eliminate ecological impact through chemical or particulate release into the environment.

Robust Single-Use Microbial Bioreactor
Cellexus Limited has launched the new and improved CellMaker PLUS single-use bioreactor system. This highly flexible, robust, and easy-to-use system comes with improved control software complete with full pH and dissolved oxygen control. This scalable system is well-suited for efficient culture of oxygen-hungry cell types and is inexpensive to use.

The CellMaker PLUS is fully automated and includes a wealth of new technologies for efficient growth of the widest range of cell types including E. coli, P. pastoris, algae, and bacteriophage, as well as the more challenging insect cells.

This single-use bioreactor system does not require mechanical methods to mix or oxygenate. While other disposable systems require shakers, rockers, rollers, or large environmental chambers, the CellMaker product line employs a novel airlift technology, available only from Cellexus.
