Fill media for beverage and food pipeline cleaning verification
After CIP, confirm with liquid media that the line is actually clean
THE SITUATION AND THE PAIN POINTS
After CIP cleaning in beverage, dairy, and food plants, residual microorganisms multiply in the next batch and spoil it. Swabbing only checks reachable surfaces; the interior of pipes, valves, and dead legs can only be verified by filling the whole section with liquid medium.
OUR APPROACH
Filling the line with a general or selective liquid medium, holding, then sampling and incubating directly verifies the cleaning result across the whole section. STBIO supplies food-grade Plate Count Broth, Nutrient Broth, Buffered Peptone Water, Lactose Broth, and others, chosen for the flora you monitor, in 5 kg and 25 kg packs for routine verification.
- Whole-line verification covering valves and dead legs
- Choose by target: total count, coliforms, lactic acid bacteria, or yeast and mould
- Food-grade raw materials, safe even if traces remain in the line
- Bulk packs keep routine verification affordable

Frequently asked questions
01How long should the medium be held in the line?
It depends on the purpose and plant procedure; a common practice is to hold for several hours to overnight, then drain, sample, and incubate. Set a standard procedure with QA according to product risk.
02How is spent medium disposed of?
Drain to the plant's wastewater process; incubated samples are autoclaved and discarded under microbiological waste rules.
