INTENDED USE
- BacterContact™ Tryptic Soy Agar + LTHTh for surface microbiological sampling with the addition of a neutralizer to neutralize surface disinfectants.
- The packaging with semi-permeable Cellophane film helps balance the humidity of the environment during storage.
PRINCIPLES
- BacterContact™ Tryptic Soy Agar + LTHTh: Pancreatic Digest of Casein is a type of peptide consisting of amino acids extracted from milk protein, which facilitates bacterial growth; Peptic Digest of Soybean Meal is a peptide extracted from soybeans, providing nutrients and growth factors; Sodium Chloride creates a saline environment to maintain the pH balance inside and outside the bacteria; lecithin (L), tween 80 (T), histidine (H), and sodium thiosulfate (Th) act to neutralize residual disinfectant chemicals.
- Prepare the surface to be tested: Clean the surface to be tested using a 70% alcohol solution or another cleaning solution. Then, wait for the surface to dry completely.
- Open the pre-packaged BacterContact plates: Ensure that the packaging of the plates is not torn or damaged before opening.
- Place the Contact plate on the surface to be tested: Press the Rodac plate onto the surface to be tested. The recommended contact time between the plate and the test surface is 10 seconds with a pressing force of 500g.
- Seal the Rodac plate: Make sure that the lid of the Rodac plate is tightly closed. Wipe the surface again with 70% alcohol.
- Evaluation of Results: Incubate under the following conditions
- 30 – 35 °C for 72 ± 6 hours (NF EN ISO 21149, NF EN ISO 18415)
- 20 – 25 °C for 3 to 5 days for Total Microbial Count (Pharmacopoeia)
RESULTS
- After incubation for the required period, usually from 3 to 5 days, the plates are examined for the presence of fungi. The results are evaluated by counting the number of fungal colonies on the plates
BacterLab ensures the quality of each product batch by testing with ATCC reference strains.
