VWR® Vortex Mixers provide fast, efficient mixing of samples in microtubes, test tubes, PCR tubes, and microplates using an orbital motion generated by an eccentric motor. Available in single-tube models (with cupped head for 1.5 mL and 2.0 mL microtubes) and multi-tube vortexers (with flat-top platform for up to 50 tubes simultaneously). Key features include: adjustable speed from 0 to 3,200 rpm, continuous and touch (pulse) operation modes, non-slip rubber feet for stable operation, and compact footprint. Multi-tube models accept various inserts including tube racks, microplates, and PCR strip adapters for versatile high-throughput mixing. Essential for cell lysis, resuspension of pellets, reagent mixing, and bead-based assay preparation. Quiet, low-vibration operation.
