Routine Water and Beverage Microbiological Analysis Using the 55-Plus™ Monitor
Filtration and Incubation of Liquid Samples
Test beverages and other liquids faster and easier with our 55-Plus™ monitors. These disposable and sterilized units are a convenient and easy system that enables you to optimize the analysis time for routine testing. After sample filtration, simply add 2 mL of liquid culture media and convert the base of the unit into a Petri dish for incubation.
Benefits
- Save time: No need for washing and autoclaving
- Faster flow rates: 50% more filtration area than conventional 47 mm filters
- Universal fit: works with the standard membrane filtration rubber stopper tulip head
- Convenient and easy to use
55-Plus™ Monitor
For maximum convenience and hassle-free maintenance, combine it with our EZ-Fit® Manifold.
Processing an aqueous sample using the 55-Plus™ monitor can be done in 5 simple steps.
| Step 1: |
Place a 55-Plus™ monitor on the EZ-Fit® Manifold with the tulip head |
| Step 2: | Pour the sample into the funnel and filter by applying vacuum. Depending on your sample properties, a rinsing step may be needed. |
| Step 3: | Insert liquid culture medium: - By the top: Add medium directly into the top of the filtration funnel and then apply vacuum to absorb medium into absorbent pad. - By the bottom: Invert the monitor and introduce the medium into the base through the bottom port. |
| Step 4: | Convert filtration unit into Petri dish by removing the funnel, replacing the lid and putting the cap on the bottom port. |
| Step 5: | Incubate upside down at the appropriate temperature and time. After the incubation period, examine and count colonies. |
