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.

• Continuous or touch modes
• Variable speed control

Designed for gentle shaking or vigorous vortexing of samples in a wide variety of applications. Use with flasks, beakers, tubes, and microwell plates. Constructed using a heavy base casting with corrosion-resistant enamel finish, units remain stable on work surfaces. The fixed speed vortex mixers are one-touch units designed for high speed mixing for vigorous vortexing of samples at 3200rpm. Mixing starts when the head is pressed down. The analog vortex mixers have a variable speed control from 100–3200rpm, which allows low rpm startup for gentle shaking or high-speed mixing for vigorous vortexing of samples. Units can be operated in touch mode when depressing the cup head or in a continuous mode. Models feature a three-way power switch and a speed knob with variable 1 to 10 dial marks.

Compact stirrers with a chemically resistant ceramic top. The elevated control panel minimises contact with spills and enables easy reading and adjustment of the temperature. Units feature digital error code display, a hot top indicator to warn user that surface is hot and the strong magnetic adhesion prevents stirring bar decoupling.

• Microprocessor control sends feedback to the motor and hotplate to maintain constant speed and set temperature
• VMS-C7 and VMS-C10 can be used with VT-5 contact thermometer, enabling precise temperature control
• Fixed safety circuit shuts off heater if temperature rises above 550 °C
• Digital display ensures accurate and repeatable temperature settings
