At the heart of the WASP is a microprocessor controlling all aspects of the deposition of liquid sample onto the surface of a rotating agar plate. Differences in agar height are accommodated by the unique stylus geometry. The stylus arm dispenses liquid samples in an Archimedes spiral, either uniformly across the plate, or as a continuous decreasing volume (equivalent to a thousand-fold dilution).

Pre-programmed options allow liquid sample to be dispensed in a variety of ways, utilising up to 200ml of sample. One impressive feature of the WASP system is the ability to load sample, inoculate a plate and then clean the stylus with a single keystroke. WASP has an automatic cleaning cycle. This uses sanitising solution from an integral reservoir and sterile water contained in autoclavable vessels. Automation of the cleaning cycle gives the operator time to remove the inoculated plate and prepare for the next sample, thus streamlining the process. User-selectable parameters can be chosen and locked, ensuring that the correct settings are always used. All controls are accessed via a full colour, purpose-designed membrane keypad.

 Vacuum Source is essential for drawing up the sample from source into the spiral plater (order separately)
