The G 7783 CD serves laboratories that reprocess glassware daily, from routine cleaning to analytical work that requires a purified-water final rinse. A laboratory technician loads the baskets, selects a programme on the front panel, and closes the door; the machine then washes, neutralises, rinses, and, where the programme calls for it, disinfects.
Programme choice follows the soiling. Programme A is a cold programme that removes problematic chemicals quickly, and programme B holds 90 to 93°C for 10 minutes for thermal disinfection to the BGA standard. The AD programmes end in a purified-water final rinse, which suits glassware that goes back into analytical use. Cleaning and final-rinse temperatures are set separately on the electronic control, with 85°C and 70°C as the usual settings.
Loading is straightforward. The top basket moves 2 cm up or down from its middle position and takes vessels up to 19 cm high, so vessels of different heights sit together in the same cycle. A TA drying unit finishes the load, and the glassware comes out ready for use.
Day-to-day running centres on supplies, and each supply has its own place in the machine. The door reservoir of about 200 ml holds rinse agent, powder detergent goes into the door dispenser, and liquid detergent and neutralising agent are dosed from behind the service panel. The softener takes salt from a container of about 2 kg. Senior laboratory staff can plan top-ups based on these quantities and schedule replacement of the dispensing hoses every 12 to 18 months.
