The ‘Starter Kit’ is the ideal way to begin if Dental Unit Water Line monitoring is new for your practice. The kit includes the mini incubator and the first box of 25x HPC Samplers. If your dental unit is plumbed to chlorinated water (eg direct from the mains), then you’ll also need the 9MER-DOSEDCT-25PK 120ml jars which contain a chlorine neutralising agent.

Millipore Samplers simplify routine microbiological analysis of liquids and surfaces for bioburden levels of bacteria.  These products eliminate the cumbersome and expensive hardware and materials associated with traditional testing techniques.

A Sampler consists of a plastic dip test handle with a 0.45 µm Millipore filter, an absorbent pad which contains the dehydrated nutrient medium for recovery of specific organisms and an outer plastic sheath which can be filled with the sample liquid of choice.  Samplers are suitable for testing high purity and environmental waters.

Once samples of waters and surfaces have been taken the Samplers can be incubated for 48 hours.  Alternatively, Samplers can be left at room temperature for 7 days to achieve results.  Colonies of growth can then be counted and estimated using the Comparison Chart provided.

For chlorinated water, obtain a sterile sample bottle containing sodium thiosulfate to neutralise the residual chlorine (9MER-DOSEDCT-25PK) (9MER-WHIRL-PAK). If the DUWL is sanitised with a chemical sanitant (peroxide, chlorhexidine gluconate based products, etc.), ask the manufacturer of the DUWL or sanitant supplier to recommend a suitable neutraliser. Neutralisers are necessary because disinfectants used to clean DUWLs may leave residuals that can inhibit recovery of microorganisms. The micro-organisms may not be killed but may be inhibited from replicating on media. This may lead you to conclude that since no colonies formed, the water is of good quality, when in fact the colonies did not form due to the bacteriostatic effect of the chemicals in the water.

The mini incubator is a fast, accurate and consistent way of incubating HPC Samplers. The incubator holds the inoculated HPC medium at 25-35°C for 48-72Hrs. The mini incubator holds 9x HPC samplers on the top shelf and 7x on the bottom shelf, so it can incubate a total of 16 at a time.

Operates on 220-240V, 30 Watts, 50-60Hz.
