SED-WSWY-H three-head microbial limit testing system. Stainless-steel body with built-in diaphragm pump for vacuum membrane filtration — no external suction flask required. Three filter heads work independently or togeth
Funktionsweise
The test sample is injected into the microbial limit culture vessel. The instrument's built-in diaphragm pump creates negative-pressure suction, drawing liquid through the membrane and trapping micro-organisms on the filter surface. The membrane is then removed with a membrane-transfer tool, placed colony-side up on solid growth medium, covered to form a closed culture box, and incubated in a constant-temperature incubator for counting.
