SM86 Sterility test system is based on the principle of Membrane Filtration by the action of directional peristaltic pressure, filling testing sample into the closed canister and filtration by the positive pressure of the device. Rinsing membrane to remove the bacteriostatic ingredient if samples included. Appropriate medium is pumped into each canister separately to promote the growth of the captured organisms. The canisters are incubated and examined for contamination in accordance with the relevant pharmacopoeia.Many types of sterile products can be tested, includes antibiotics and drugs containing antibacterial ingredients, infusion, injection, sterilization medical equipment, sterile water for injection, etc.
