Glas-Col振荡器主要有由电容器和电感器组成的回路，通过电场能和磁场能的相互转换产程自由振荡。要维持振荡还要有具有正反馈的放大电路，又分为变压器耦合式和三点式振荡器，很多应用石英晶体的石英晶体振荡器，还有用集成运放组成的振荡器。
Multi-Tube Pulse Vortexer
The 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 aailable for test tubes and centrifuge tubes and can be used with capped or uncapped tubes.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:
