Medical-grade material: made of medical-grade PETG/PE material, it is firm and not easy to break, which can reduce human safety hazards and is an ideal choice for shaking culture application;

High transparency: the surface smoothness meets the requirements of mirror, and the permeability is close to glass, which reduces the risk of cell adhesion;

Accurate calibration: the calibration of the bottle body is clear and accurate, which is convenient for observing the medium capacity;

Bottle cap design: each specification has two kinds of sealing cap and breathable cap, and the breathable cap contains 0.22um PTFE filter membrane, which ensures sterility while providing gas exchange and minimizes the risk of pollution; All conical shake bottles are sterile and enzyme-free, and are suitable for the culture of suspended cells and bacteria.
