This Glas Col Pulsing Vortex Mixer   Shaker 099A PVM12 is in real good condition and functions 100% . It came from a local lab that was upgrading equipment. We can accept pay-pal or your credit card. Please email me with any questions.

Glas-Col's patented pulsing feature is what makes these vortexers stand apart from other mixers. The pulsing action allows the vortex to collapse, before throwing back a full vortex. This time delayed sequence helps to join the upper and lower strata for more thorough and reproducible mixing.
