The 96 well plate sample pretreatment device is a positive pressure type sample pretreatment device designed specifically for drug research and development laboratories and biological sample analysis laboratories. This device is suitable for 96 well solid-phase extraction plates, SLE plates, PPP plates, and filtration plates produced by different manufacturers. Functional features Each hole has equal pressure, reducing flow velocity errors between holes Enhance the balance and reproducibility of extraction High throughput, processing 96 samples simultaneously to improve work efficiency Suitable for high viscosity blood samples and biological samples Dual pressure regulation meets different requirements for sample processing The pipe rack design allows for the use of collection plates of different heights and allows for direct observation of the liquid passing through the sample processing plate Easy to operate, only requires a gas source for operation, no power supply is needed Sample pretreatment can be completed in an inert gas (nitrogen) environment Accurate adjustment of pressure damping and stable pressure control.
