easySpiral Dilute

easySpiral Dilute is an automatic diluter and plater of Petri dishes. It allows 1/10^th serial dilutions and plating up to 6 log. dilution on 1 single Petri dish. For a sample of 30 to 1 x 10¹² bacteria, no more manual dilutions and plating is automatic.

• Automatic cycle of 5 successive dilutions at 1/10^th
• Plating modes: exponential, constant, circle, pour plate
• Counting range: from 30 to 1×10¹² CFU/mL
• Plating cycle time: 134 seconds

TheeasySpiral Dilute plater is used for enumeration during microbial control.

The Spiral plating technique allows 4 log dilutions on the same plate and the automatic dilution ramp of the device allows for the increase of the enumeration range. This technique is adapted to the realization of challenge-tests requiring several dilutions to the 10th before plating. The Spiral technique is also used for the detection of quality indicators with a criterion higher than 100 CFU/g. The ISO 4833-2 defines the use of this technique for the research of total flora.
