Features:
The KNF LABOPORT N840.3FTP two-stage diaphragm vacuum pump is suitable for use with concentrators, rotary evaporators, and distillation equipment (sold separately). The pump has a 34 liters per minute (LPM) free air capacity with vacuum to 8 Torr and its polytetrafluoroethylene (PTFE) air flow path is corrosion resistant. The oil-free diaphragm pump allows operation without oil misting and contaminated oil disposal. The pump accepts 115V, 60 Hz input power.
KNF Neuberger, a division of KNF Group, manufactures diaphragm pumps and systems for gases, vapors, and liquids for laboratory and manufacturing applications. The company, founded in 1977, is headquartered in Trenton, NJ.

The new Vi-CELL Series Cell Viability Analyzers provide an automatic and cost effective means to perform the trypan blue dye exclusion method. This data is essential to the decision making process for basic tissue culture cell passage and maintaining optimum culture conditions in bioreactors. Cell and tissue culture applications in life science research, including recombinant protein and biopharmaceutical production, require the accuracy, precision and automation available only in the Vi-CELL cell viability analyzer.
The Vi-CELL automates the widely accepted trypan blue cell exclusion method. Historically, cell viability determinations were performed manually using a light microscope and hemacytometer. This technique has major shortcomings due to subjective determination of cell count, as well as manual, time consuming steps. In comparison to the manual technique, the Vi-CELL automatically performs the trypan blue with video imaging of the flow-through cell. Results are obtained in minutes.
