ROX-Free DNA Polymerase Kit

November 8, 2005 5:27 am | Articles | Comments

QTaq ROX-Free DNA Polymerase Kit, for real-time quantitative PCR (qPCR), allows individual adjustment of passive reference dye concentration. Because the ROX dye is provided separately, users can determine the best passive reference dye concentration for their experiment or omit ROX altogether.

Rotational Vacuum Concentrator (6617)

November 8, 2005 5:27 am | Articles | Comments

MAXI–concentrator type RVC 2-33 is suited for large sample volumes and all commonly used solvents. Typical applications include evaporation of multiple small samples within biology, microbiology, biochemistry, DNA/RNA (ethanol, methanol), PCR and HPLC (solvents mainly water/acetonitrile).
