The samples supplied are lyophilised vials, which require reconstituting with your laboratory's own sterile deionized water. Depending on your order, up to four samples may be supplied for each distribution:
Sample A: For Total Coliforms & Escherichia coli, this sample contains Escherichia coli and another coliform organism.
Sample B: For Colony Count (22°C/3 days), Colony Count (37°C/2 days).
Sample C: For Enterococci together with Clostridium perfringens* AND Pseudomonas aeruginosa. *NB another Clostridium/Pseudomonas species may be added to test the laboratory's ability to confirm Clostridium perfringens / Pseudomonas aeruginosa.
Organism Identification: This is a lyophilised vial which requires rehydrating. The vial has been inoculated with a Gram negative rod-shaped organism but please note, occasionally a Gram positive organism may be used. The organism chosen is one which is routinely recovered from water.
