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. All VWR Analog Vortex Mixers include both cup head and three-inch head with cover.
