BIOHIDRICA® COMPACT DRY

COMPACT DRY

Compact Dry is an easy test method which helps to reduce the time needed to perform microbial testing in raw materials as well as finished products like food, beverage, meat, cosmetic or other samples.

Formats
	Compact Dry TC is a medium for total viable bacterial count, which contains nutrient standard agar. The colonies grown on Compact Dry TC are red due to redox indicator tetrazolium salt. Regression line data from Compact Dry TC method plotted versus the conventional PCA method (standard plate count agar) shows a good correlation per 100 food samples for the population of mesophilic aerobic micro-organisms.
	Compact Dry EC is a medium for E. coli and coliforms. The medium contains two kinds of chromogenic enzyme substrates: Magenta-Gal and X-Gluc. E. coli forms blue colonies. The total coliform group count is the sum of both the red and blue colonies.
	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 colourless colonies.
	Compact Dry SA is a medium used to determine Staphylococcus aureus by means of selective growth and differentiation. S. aureus can grow as blue colony. Other bacteria can grow as distinguishable colony or their growth is inhibited. Rapid detection Incubation time is 24hrs at 35°C. Shelf life is 15 month at room temp. (Realtime stability test is ongoing) Staphylococcus spp. except for S.aureus can grow as small white colony. Other bacteria forms distinguishable colony (white or magenta) if it grows on X-SA plate.
	With Compact Dry YM yeasts and mould can be differentiated by colour development. The medium contains the chromogenic enzyme substrate X-Phos which turns blue with many yeasts. Moulds form fluffy colonies with a characteristic colour. Antibiotics inhibit the growth of bacteria. The Compact Dry YM allows a very good 3-dimension growth of yeast and mould.

TECHNICAL DATA

Features & Benefits:

Compact Dry is a ready-to-use test method which helps to reduce the time needed to perform microbial testing. Therefore, it allows maximum productivity by increasing efficiency. The Compact Dry plates can also be used as a contact plate for difficult areas using the Compact Dry swab.

Compact Dry is an easy-to-read results test method. Place 1 mL of sample onto the plate, the liquid samples will self diffuse evenly over the whole plate. Incubate the plates at the temperature specified in the package inserts. The grown colonies are pigmented with different colours, developed by chromogenic substrates and redox indicators. The type of bacteria is identified by its colour. For further investigation bacteria can be easily selected.

Compact Dry is also an easy-to-store test method. The plates can be kept at room temperature for up to two years and can be used over an incubation temperature range of 20-42°C.

Compact Dry is a very safe and convenient product. Its rigid structure allows for easy transportation and an unlimited number of units can be stacked safely in an incubator. The risk of contamination of the medium is eliminated by using the covering lid.

Additionally membrane filters can be tested using Compact Dry plates. Filter 1mL water or any other liquid using an ordinary membrane filter (e.g. 47 mm, 45 µm), then pipette 1 mL of sterile water into the middle of the Compact Dry plate and place the filter on the Compact Dry plate. The filter should be trap side up. Colonies will grow on the filter.
