Spiral Plater ® DS + - INTERSCIENCE

The Spiral Plater System® method allows rapid bacterial enumeration while avoiding all or part of the intermediary dilutions. A logarithmically decreasing volume of sample is dispensed on the surface of a rotating Petri dish in an Archimedes spiral. The volume is calibrated and known at every point of the Petri dish. Bacterial concentration is determined by dividing the number of colonies found by the volume dispensed in the same sector of the dish.

Spiral Plater ® DS + advantages:

• Microprocessor control
• Dispensing time : 8 seconds
• Savings on Petri dishes, agar, pipettes…
• 100% automatic sample-taking, disinfecting, rinsing.
• 250µl of sample drawn in one cycle for plating of successive dishes : 5x50µl.
• 50 or 100µl of sample plated on the same dish for stronger concentration.
• Three possible dispensing modes : Spiral® exponential, variable, uniform.
• Numerous safety features.
• Continuous supply of disinfecting liquids
• Counting range from 200 to 500,000 cfu/ml for 90 mm Petri dishes and up to 4,000,000 for 150 mm Petri dishes.
