1. Completely stop: to avoid the continuous spin dehydration too dry, provide a predictable concentration factor, in the case of processing several samples at the same time, without calibration.
2. Vertical filter membrane: parallel to the filtrate instead of vertical, so it is not easy to be clogged, no waste, and rapid filtration. It can achieve 25 to 80 times concentration in one step.
3. Wide range of chemical compatibility: heat-sealed filter membrane eliminates adhesion and downstream extract problems;
compatible pH range: 1 to 9.
compatible pH range: 1 to 9.
4. Reverse rotation recovery: The protein can be recovered to the fullest without introducing errors in suction; the low-binding filter membrane and polypropylene housing can achieve 90% sample recovery.
5. Reliability: Rotate precious samples in a solid and smooth integral device without leakage.
