Glas-Col振蕩器主要有由電容器和電感器組成的回路，通過電場能和磁場能的相互轉(zhuǎn)換產(chǎn)程自由振蕩。要維持振蕩還要有具有正反饋的放大電路，又分為變壓器耦合式和三點(diǎn)式振蕩器，很多應(yīng)用石英晶體的石英晶體振蕩器，還有用集成運(yùn)放組成的振蕩器。
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:
