  • WASP Spiral Plater

    The WASP 2 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. The WASP2 spiral plater makes spiral plating easy.

    WASP Spiral Plater

    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.

    To ensure less-experienced users can operate the instrument with minimal risk of inaccurate results, the user-selectable parameters can be chosen and then locked. All controls are accessed via a full-color, purpose-designed membrane keypad.

    The WASP 2 is used in conjunction with the Vacuum Source, which is necessary for drawing liquids through the system. The unit will inoculate the plate at fastest speed possible without centrifugal force causing the sample to be pushed to the outside of the plate. There is no set-up procedure, simply “plug and play.” There is easy access to all serviceable parts.

    Key Benefits

    • Use without any consumables ensuring minimal running costs.
    • A single keystroke operation loads the sample, inoculates a plate and cleans the stylus to optimise sample throughput speed.
    • It can dispense volumes from 10 µl to 400 µl providing immense flexibility and repeatability.
    • 8 x 50 µl plates can be prepared in Syringe Mode in 2 minutes 35 seconds.
    • Optional 15cm turntable to enable the use of 15cm plates.
    • Optional self-centering, adjustable turntable – allows 9cm plates from different manufacturers to be used without manual adjustment.

    WASP Touch provides Automated Intelligent Monitoring Software (AIMS) to guide you through set-up and daily check routines - ensures consistent trouble-free plating.

    • Sample may be aspirated from beakers, bottles and tubes – providing maximum flexibility in use.
    • Automatically logs date, time, deposition, user name, number of plates produced – a powerful diagnostic tool.
    • Precise quantities of sanitising fluids are dispensed automatically to maintain optimum levels. This ensures effective and efficient sanitisation takes place.
    • Sanitising system reservoirs contain sufficient fluid for over 900 wash cycles – perfect for busy laboratories.
    • Fully integrated vacuum waste system – occupies the smallest amount of bench width.
    • Optional fully comprehensive maintenance and breakdown contracts are available to prolong the life of your investment.

    All this and it produces perfect plates!
