EasySpiral "Dilute"
[3rd Generation]

The world's first automatic diluter & plater:

a 2-in-1 automatic diluter and plater, which allows you to do 5 x 1/10th serial dilutions. It will then automatically plate on 1 single Petri dish, with a countable range of 30 to 10 million countable CFU/mL.

Spiral plate after incubation Features of the easySpiral Dilute
  • Compact 38 cm wide, can be used inside and outside a laminary flow Stainless steel housing

  • High precision glass syringe Typical accuracy of 0.5 % No more pipet calibration

  • Fast rotating arm 5 dilutions and 1 plating in 100 sec.

  • Automatic disinfection Using Overflow technology No cross contamination

  • One button touch For 10-5 dilution and plating.

Introduction to EasySpiral Plating
The EasySpiral is a microprocessor controlled dispenser that deposits a liquid sample in a spiral pattern onto the surface of a rotating agar plate. The dispensing stylus deposits decreasing amounts of sample as it moves from the center of the plate outwards. Because of this unique plating action, microbial suspensions (~ 400 to 400,000 cfu/ml on 100 mm plates ) that may normally require several serial dilutions prior to plating can be plated directly The spiral method allows rapid bacterial counting while avoiding some or all intermediate 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 is known at every point of the Petri dish. The bacterial concentration is determined by dividing the number of colonies found by the volume dispensed in the same sector of the dish.
