This useful washing/rinsing system allows pipettes and burettes to be automatically rinsed when connected to a tap and drain outlet. Particularly useful where unpleasant or hazardous liquids have been used, the apparatus holds pipettes and burettes up to 600 mm in length. For convenience and flexibility, the washing/rinsing system is available as separate components. 1. The polyethylene rinser/washer fills via the spray nozzle on the top rim. Contaminated water will syphon out totally, once the syphon point at the top of the rinser has been reached via the large diameter drain situated at the lowest point, before refilling automatically. 2. During washing the pipettes/burettes are housed in a specially designed basket, which minimise breakages as it buffers the glassware tips against the soft polyethylene base. 3. A soaking jar is available, which will hold pipette/burette basket, to allow the glassware to soak before rinsing. Low water flow rate is NOT problem, but it is better to adjust the flow for cycle of about 90 seconds.

This water still produces ready-to-use cold, distilled water. The high quality borosilicate glassware coupled with silica sheathed heaters gives pyrogen-free distillate of the highest purity from virtually any raw water supply. The boiler feed is pre-heated to increase efficiency. The unique condenser design ensures that the droplets of distilled water remain in contact with the cooling coil for the longest possible time ensuring maximum energy transfer. All-glass construction allows rapid descaling using strong mineral acids. built- in ""clean"" function and integral acid addition funnel make the cleaning operation simple and safe with no need to dismantle any of the glassware. large bore stopcock with PTFE key is fitted for easy draining of chemicals after cleaning. A flow sensing device prevents overheating, and allows the unit to run on water supplies with pressure as low as psi (20 kPa). Requires a minimum flow of 1 litre per minute. There is an over-temperature thermostat mounted in the boiling chamber as an additional fail-safe. The acrylic safety screen and the cabinet lid are removable giving easy access to the glassware components. Screw threads are incorporated on all water connections so hoses can be fitted and removed easily and safely without risk of breakage. The control is simple and effective system which can be fitted to virtually any type of reservoir vessel.
