When a microbiology result is unclear, repeating the run without changing the decision process rarely solves the underlying problem. This guide uses the manufacturer IFU for catalogue 610347 as its technical anchor and translates it into practical review questions for professional laboratories.
Start with the product’s documented role
ACID BROTH is a medium for the cultivation of acid tolerant microorganisms from canned foods.

Design the workflow before opening the pack
Define the sample type, inoculum or preparation step, incubation conditions, control organisms, reading window, confirmation pathway, and acceptance criteria in the SOP. Record the catalogue number, lot, expiry, analyst, equipment, and any deviation that could change interpretation.
Preparation checkpoint
Suspend 28.0 g of powder in 1 litre of distilled or deionized water. Heat until completely dissolved. Sterilize in the autoclave at 121 °C for 15 minutes.
Procedure points worth controlling
Inoculate the medium with the sample to examine. Incubate at 55 ± 1°C for 18-48 hours.
Read and document the result
Growth is evident in the form of turbidity.
Storage and handling
The powder is very hygroscopic: store the powder at 10-30 °C, in a dry environment, in its original container tightly closed and use it before the expiry date on the label or until signs of deterioration or contamination are evident. Store prepared media at 2-8°C. WARNING and
Safety and professional-use reminder
The product is not classified as hazardous by current legislation and does not contain harmful substances in concentrations of ≥1%. It is nevertheless recommended that the Safety Data Sheet be consulted on its correct use. The product must be used only by properly trained operators.
A practical pre-release checklist
- Current IFU revision and catalogue code verified
- Receipt, storage, lot, and expiry documented
- Controls and acceptance criteria defined before testing
- Reading time and observations recorded without forcing an ambiguous endpoint
- Confirmation and deviation actions linked to the laboratory SOP
Final perspective
Useful technical content should help a laboratory make a better-controlled decision, not replace the IFU or validated method. Confirm the current manufacturer documentation and local regulatory requirements before implementation.
