VWR® heavy-duty vortex mixers have an efficient motor enabling units to operate in continuous mode and handle all accessories over the entire speed range. Choice of two modes of operation: 'Touch' mode for mixing tubes when the cup head or universal holder with cover is depressed or 'On' mode when using any of the accessory attachments for continuous operation.

• Both units designed for continuous duty
• Can be used at 4 to 40 °C (85% relative humidity, non condensing), in an incubator, CO₂ incubator or cold room
• Digital model has LED displays for speed and time

The analogue unit is a variable speed mixer designed for continuous duty, and the digital version is ideal for applications that demand repeatable results. This model features touch pad controls and LED displays for accurate speed (rpm) and time (minutes and seconds) results. Microprocessor control maintains set speed for strong, consistent mixing action. Timer will display elapsed time or, when programmed to user-defined time limits, the unit will shut off when time reaches zero.
