The strongest purchasing decision connects the catalogue item to the method, documentation, storage capacity, and expected workload. This guide uses the manufacturer IFU for catalogue 620313 as its technical anchor and translates it into practical review questions for professional laboratories.
Start with the product’s documented role
ACETAMIDE BROTH is a dehydrated medium used for the confirmation of Pseudomonas aeruginosa in bottled water.

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 17,2 g of powder in 1 litre of distilled or deionized water. If needed, heat gently to dissolve completely. Sterilize by filtration. Aseptically dispense into sterile test tubes.
Procedure points worth controlling
Inoculate with one or two loopfuls of growth from a presumptive fresh medium (ASPARAGINE ENRICHMENT BROTH code 610138) . Incubate at 36 +/- 1°C for 2-4 days.
Read and document the result
A positive reaction is indicated by a color change of the tube from orange-red to an intense purple-red. The presence of P.aeruginosa is confirmed by a positive asparagine test and a positive acetamide test.
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 classified as hazardous by current legislation. It is recommended that the Safety Data Sheet be consulted before 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.
