Fixed Speed Vortex
VWR Fixed Speed Vortex Mixers are one touch units that are designed for high speed mixing. Starts mixing when the head is pressed down. Speed is fixed at full rpm to provide vigorous vortexing of samples.

Analog Vortex
VWR Analog Vortex Mixers have a variable speed, analog control that allows low rpm start-up for gentle shaking or high speed mixing for vigorous vortexing of samples. Choose from two modes of operation; continuous mode when using accessory attachments or touch mode which activates mixing when depressing the cup head.

Digital Vortex
VWR Signature Digital Vortex Mixers are ideal for applications that demand repeatable results. Mixers feature touch pad controls and LED displays for accurate speed(rpm) and time(minutes/seconds) results. Micro-processor feedback control maintains set speed for strong, consistent mixing action. Timer will display elapsed time or when programmed to user defined time limit, the unit will shut off when time reaches zero. Choose from two modes of operation; continuous mode when using accessory attachments or touch mode which activates mixing when depressing the cup head.

Pulsing Vortex
Powerful pulsing vortex action produces excellent cell disruption for glass bead procedures. The VWR Signature Pulsing Vortex Mixer is capable of complete cell disruption of samples in only minutes. Unique pulsing action reduces heat generation while providing more effective mixing and disruption. System includes an easy-to-load holder for (12)1.5ml or 2.0ml micro centrifuge tubes. Micro-tube holder has a built-in cup head which allows mixer to be used as a standard vortex mixer in touch mode. Micro-processor feedback control maintains set speed for strong, consistent mixing action. LED displays for both speed(rpm) and time (minutes/seconds) which provides better repeatability and accuracy. Displayed time counts up during continuous operation and counts down during timed runs.
