The new cartridge design of Glas-Col' s Multi-Pulse Vortexer allows the user to switch the size of tubes to be mixed simply by changing the cartridge size, thus eliminating the need for extra racks. Cartridges are available for test tubes and centrifuge tubes and can be used with capped or uncapped tubes. The blank cartridges allow the use of most standard tube racks. Each cartridge is constructed of chemical resistant foam and ABS plastic. The unit easily adjusts for different height tubes. The contents of the tubes remain visible during mixing, and sample can be added to uncapped tubes without stopping the action. Other features include: variable speed.

pulsing feature interrupts vortexing to join upper and lower strata for more thorough mixing.

DC motor with filtered control for smoother operation and longer motor life.

The drive base and upper section are hardcoat anodized for resistance to most acids and solvents.

Each Multi-Pulse Vortexer comes with two cartridges, one for 12-13 mm diameter tubes and one for 15-16 mm diameter tubes.
