VWR®, Multi-Tube Vortexers

Designed to hold multiple test tubes, test tube racks, vials or cylinders. Vortexing action is created by securing the top of the vessel in place while allowing the bottom to move freely in a defined orbit. Two stainless steel posts hold the support plate securely in place for quiet, rattle-free mixing. The support plate is easily adjustable by loosening knobs and moving the support plate up and down. The circular groove around the top of the taller post allows the support plate to be swung away from the tray for easy removal of samples. The suction cup feet dampen motion and prevent the unit from moving along the work bench. Made from stainless steel with corrosion resistant paint. Equipped with a powerful, permanent magnet motor with sealed ball bearings. Motor is rated for continuous duty.

• Ideal for mixing many tubes at one time
• Handles larger volumes than standard vortexers
• Analogue and digital models available

Analogue vortexer (444-7063) has adjustable speed with an automatic timer for simple repeat procedures and a conveniently angled front panel.

Digital vortexer (444-7061) features a microprocessor controller for digital programming of both speed and time and a pulse feature for difficult mixing applications. Ideal for applications that require accuracy and repeatability. Digital readouts of both speed and time are easily viewed from the easy to read LED display.

Timer can be programmed or can be run in continuous mode. Versatile pulsing feature stops and starts the unit in pre-determined increments to add further agitation to mixing process. Pulsing program can be set from 1 second on/off up to 59 seconds on/off, allowing for a wide variety of pulsing combinations. The operator can set the pulsing features to run for 1 to 59 seconds and have a delay of 59 seconds, then the cycle repeats. Pulsing can be used in both timed and continuous mode.

Delivery information: Supplied with one 50×12 mm blue test tube rack (444-7066). Additional colour coded foam test tube racks, post extension kit and replacement tray pad set are sold separately. Each unit is supplied complete with three plugs: EU, UK and CH for use throughout Europe.
