The "Zartclear" series is a one-step cell culture supernatant clarification filtration unit that eliminates the need for centrifugation. It contributes to saving your time and costs. Thanks to the filtration aid (diatomaceous earth), filtration proceeds without clogging. Furthermore, it not only allows for the filtration of cell culture supernatant while retaining the cells but also enables simultaneous clarification and sterilization filtration of the culture supernatant. Centrifugation before filtration is no longer necessary, saving both time and the cost of centrifuge tubes. 【Features】 ■ No pre-treatment required with centrifugation ■ Clarification and sterilization of cell culture supernatant can be performed in one step ■ Significantly reduces working time in the lab ■ Saves costs on centrifuge tubes ■ No clogging due to the filtration aid
