Product Description

The biological culture indicator is a biological testing tool used to detect microbial contamination and is widely applied in the monitoring of microbial conditions in medical equipment, pharmaceutical factories, water treatment systems, and other environments. It consists of a culture medium and microbial indicators. The culture medium provides nutrients and a growth environment, while the microbial indicators are specially cultivated and purified microbial cells that can produce specific microbial reactions to detect whether the corresponding microorganisms are present in the sample.

🔹 Key Specifications

Purpose: For biological monitoring of ethylene oxide sterilizers.

Mechanism: The spores are those of Bacillus subtilis var. niger. Tested with a standard resistance meter: the survival time is 15 minutes or more, and the killing time is 60 minutes or less.

Usage & Reading Methods

1

Placement: Place the ethylene oxide sterilized biological culture indicator in a standard test kit inside the pot at different positions according to national standards.

2

Incubation: After sterilization, remove the biological indicator. Squeeze the internal ampoule and place it with a control tube in a 37°C incubator.

3

Result Reading: After 48 hours, if the tube stays green, sterilization passed. If it turns yellow, sterilization failed. Control tubes must be positive (yellow) to validate the test.

4

Storage: Store at 15-30℃ with 35-60% relative humidity. Avoid proximity to sterilizers and chemical disinfectants.
