How We Make Our Liquid Culture
You can't see contamination when you buy liquid culture. So we work as clean as possible, at every step.
Isolated genetics
Every culture starts from clean, agar-isolated genetics, not straight from spores.
Sterile preparation
Nutrient broth is pressure-sterilised in closed jars with filter patches and injection ports. Needles, syringes and caps are sterile.
Laminar flow hood work
All work happens in front of a laminar flow hood, with gloves and surfaces disinfected with 70% isopropyl alcohol.
Incubation & inspection
Cultures grow at stable temperatures and are checked regularly. Anything that looks off is discarded.
Batch testing on agar
Two syringes from every batch are tested on agar plates for contamination.
Labelled & packed fresh
Every syringe is labelled with strain and batch number, and made fresh to order.
Free replacement guarantee
If your liquid culture turns out to be contaminated, we replace it for free.
