Lot of 5 VWR Analog Vortex Mixer

Lot of five VWR Analog Vortex Mixers, benchtop vortexers used for routine mixing and resuspension of samples in tubes, vials and small vessels. Each unit is a compact, weighted benchtop vortexer with a rubber cup head mounted on an orbital drive, suitable for general laboratory sample preparation.

All five units show the same VWR Analog Vortex Mixer front panel (photo 1): a variable speed control knob marked "speed" and an auto/off/on rocker switch, giving the two standard modes of operation - continuous running for use with accessory attachments, and touch (auto) mode that starts mixing when the cup head is depressed. VWR's published data for this mixer lists variable speed control of approximately 300 to 3200 rpm with a 4.9 mm orbit, and electrical requirements of 120 V, 50/60 Hz, single phase, 1.2 A (135 W). Each mixer is supplied with an attached line cord; cords are visible with the units in photo 1.

The units were removed from an R&D facility (field notes: Lifordi NH lot 96 - VWR Analog Vortexer) and are shown grouped in a stainless steel tray as they were pulled from service. The housings show typical laboratory use - surface soiling and marker/ink marks on two of the units - and all five carry the standard black rubber cup head. No additional accessory heads or attachments are shown in the photo. The units were not tested and no power-on status was recorded by the field user.
