Compact Dry CF
- Ready and easy to use portable plate: Preparation of medium is not required, which eliminates waste of medium as well as sterilizing apparatus to prepare the medium.
- Detection of colonies on plate is simple and clear.
- Single colonies on the plate can be isolated for further identification tests
Ready-to-use petri dishes for reliable microbiological analysis for coliforms
Compact Dry CF is an easy tool for the detection of coliforms. Coliforms grow with blue/blue green colonies as the recipe contains the chromogenic enzyme substrate X-GAL. The growth of bacteria other than coliforms is mainly inhibited but in case of growth they form colorless colonies. Compact Dry CF is AOAC, MicroVal und NordVal approved.
Incubation time and temperature: 24 ± 2 hours at temperature recommendation by Microval 37 ± 1 °C , AOAC 35 ± 2 °C
Shelf life: 24 months after manufacturing
Storage: Room temperature (+ 1 to + 30 °C)
Viable count in water or liquid foodstuff
Drop 1 ml of specimen (dilute if necessary) on the middle of the Compact Dry plate.
Viable count in solid foodstuff
Add buffer solution (e.g. 0.9% saline solution, PBS, buffered peptone water, etc.) to the sample and homogenize by stomacher®. Drop 1 ml of specimen (dilute if necessary) on the middle of the dry sheet of the Compact Dry plate.
Viable count in swab test specimen
Use a sterile wet swab to wipe the surface which should be analyzed and put it back into the device with wiping solution. After shaking the device (approx. 10 seconds) drop 1 ml of wiping solution (dilute if necessary) on the middle of the Compact Dry plate. Use the Compact Dry Swab (Art. No. ZCS1002953, content 40 pcs) as single application (1 ml) or Promedia ST-25 (Art. No. Z0302, content 10 pcs) as multiple application (10 ml) for this procedure.
