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.

Systec Autoclaves D Series

Features:

Innovative automatic safety door lock. Easy and safe. When the lid is closed, the lid is automatically locked by a circumferential ring system. A special lip seal made of heat resistant silicone provides reliable sealing. As steam pressure builds the seal becomes tighter.The lid also opens easily – either at the push of a button or automatically at the end of a sterilization cycle. The door-locking system is temperature dependent and adheres to national and international safety standards. The door remains locked as long as there is excess pressure in the chamber. The lid, like other parts of the pressure vessel and housing, is made of stainless steel. The modern design faceplate, which also contains the control panel, display and part of the control technology, is made of heat resistant and insulated plastic. There is no risk of the operator coming into contact with hot components.

Controls – new generation.Microprocessor and softwareThe Systec V-Series autoclaves have “comprehensive intelligence”: Pressure is controlled via an electronic pressure transducer. Additionally, there is a flexible temperature sensor in the sterilization chamber or in a reference vessel (for liquids) and another sensor at the coldest part of the chamber, the condensate outlet. The microprocessor, specially developed for our laboratory autoclave, controls all relevant functions such as steam pressure, temperature and sterilization time as well as optional rapid cooling, pre / post-vacuum and drying.

Design – pure innovation! Steam generation! A steam generator is incorporated in the housing providing substantial benefits:

– No heating elements and no reservoir for dirty water in the chamber

– With stand-by pre-heating option, only 10 min. heating time to 121° C with an empty chamber

– Improved removal of air from the empty chamber via pulsed heating (rapid attainment of optimal steam atmosphere, even without a vacuum)

– Accuracy better than ± 0.3 C with empty chamber

– Quicker cooling as neither hot water in the chamber nor the separate steam generator need be cooled

– After cooling, steam is immediately available for the next sterilization run.
