WASP Spiral Plater - Spiral Plating Eliminate Serial Dilutions

The WASP2 spiral plater boasts a host of innovative features ensuring it is still the most widely used spiral plater. It eliminates the need for serial dilutions, offers a reduction in cost per test and standardizes counting methods.
Fully microprocessor controlled and allowing depositions onto 10cm and 15cm plates in logarithmic volumes of 50ul,100ul and 200ul and a linear deposition of up to 400ul. The stylus arm dispenses liquid sample either uniformly across the plate or as a continuously decreasing volume, equivalent to a thousand-fold dilution. The unique stylus geometry and volume allows deposition on plates of varying agar height and up to eight consecutive depositions from one sample draw without the need to wash or collect more sample.



One feature unique to WASP 2 is its ability to load sample, inoculate a plate and then clean the stylus with only one keystroke. WASP 2 has an automatic cleaning cycle, with provision for both sterile water and a self-leveling bleach reservoir system. The automatic wash cycle uses a large, 500ml disinfectant reservoir, as well as autoclaveable 100ml containers for sterile water. This eliminates contamination problems associated with using a large, replenishable reservoir. Automation of the cleaning cycle gives the operator time to remove the inoculated plate and prepare for the next sample, thus streamlining operation.
