Levram Lifescience’s V-LOCK Microcentrifuge tubes are high strength, durable and autoclavable tubes with transparent and fine graduations, with on tap lock snap caps that are non-porous. Levram’s V-LOCK comes in two types, in volumes ranging from 0.1 to 1.5 and 0.5 to 2.0. The primary utilization is for centrifugation to test samples in order to separate two immiscible solutions or for precipitation of solute from solvent. These tubes are very useful in storing samples for culture growth, DNA/RNA extraction, amplification, PCR, blotting experiments, gel electrophoresis etc or any molecular biology experiment.
