Miele G 7883 CD

The G 7883 CD serves laboratories that reprocess glassware in volume and keep a mix of vessels in circulation: test tubes, pipettes, and narrow-necked glasses. A laboratory technician fills the baskets, selects a programme on the MULTITRONIC Novo Plus control, and closes the door; the washer then runs its closed circuit of washing, neutralising, rinsing, disinfecting, and drying.

Programme choice follows the load. STANDARD UNIVERSAL INTENSIVE covers routine household use, and ORGANICA addresses the two kinds of residue. PLASTICS suits temperature-sensitive labware. SPECIAL 93°C-10' holds a 93°C main wash for 10 minutes for thermal disinfection, and VARIO TD holds for 5 minutes. Wash and final-rinse temperatures and hold times are set in the programme menu, from 30 to 93°C and from 1 to 15 minutes, and one open slot takes a laboratory's own programme.

Batch capacity shapes the day. One batch holds 1,600 test tubes, 96 pipettes or 37 narrow-necked glasses, so high-throughput benches clear a large volume per programme. The upper basket docks directly to the water circuit, which supplies narrow vessels with water at the point of use.

The EU 4 pre-filter has a service life of about 100 operating hours and the H 13 HEPA filter about 500, which gives drying a predictable maintenance calendar. Supervisors and quality staff use the serial interface for process documentation, and service engineers use the optical interface. The washer is insulated and double-skinned, sits built under or free-standing in a 90 cm wide space, and its hot-air drying unit finishes each batch before the baskets come out.

A 1,600 test tube batch

One batch holds 1,600 test tubes, 96 pipettes or 37 narrow-necked glasses. High-volume benches clear their glassware in a few programmes.

A 90 cm wide, built-under fit

The washer measures 700 × 900 × 820–850 mm and sits built-under or free-standing. A 535 mm wide cabinet serves the load.

Narrow vessels flushed at the source.

The upper basket docks directly to the water circuit. Narrow-necked glasses and pipettes receive water through the basket.

Ten programme positions

SPECIAL, VARIO TD, ANORGANICA, ORGANICA, STANDARD, UNIVERSAL, INTENSIVE, PLASTICS and Rinse sit beside one open slot. The mix of residues in a laboratory finds a matching programme.

Thermal disinfection at 93°C

SPECIAL 93°C-10' holds the main wash at 93°C for 10 minutes. VARIO TD holds for 5 minutes.

A programme for temperature-sensitive labware

PLASTICS suits temperature-sensitive labware. The programme sits in the same menu as the rest.

Two integrated dispenser pumps and a supply drawer

Liquid detergent and neutralising agent come from two 5-litre containers in the drawer. Dosing runs inside the machine.

Hot-air drying with an H 13 HEPA filter

A 0.3 kW fan and a 1.8 kW heater move 55 m³/h through an EU 4 pre-filter and an H 13 HEPA filter. Temperature and time are programmable.

Process documentation by serial interface

A serial interface supports process documentation. Quality staff hold data for every programme run.

900 mm washer-disinfector

The G 7883 CD is a 900 mm laboratory glassware washer-disinfector for built-under or free-standing use.

MULTITRONIC Novo Plus control

The control offers ten programme positions, with wash and final-rinse temperatures of 30 to 93°C and hold times of 1 to 15 minutes.

SPECIAL 93°C-10'

A 93°C main wash is held for 10 minutes. The programme performs thermal disinfection.

VARIO TD

A thermal disinfection programme with a 5-minute hold.

Programme range

ANORGANICA, ORGANICA, STANDARD, UNIVERSAL, INTENSIVE, PLASTICS and Rinse cover the washing routines, and one open slot takes a laboratory's own programme.

Demineralised water option

The main wash and rinse can use fully demineralised water. A demineralised inlet serves that supply.

Closed circuit

Cleaning and thermal disinfection take place in a closed circuit. A circulation pump delivers up to 400 l/min.

Wash cabinet

The cabinet is 535 mm wide and 500 mm high. Two spray arms work in the cabinet, and a third sits on the upper basket.

Direct basket docking

The upper basket docks directly to the water circuit. Narrow vessels receive water through it.

Four-stage filtration and flowmeter

Four-stage filtration and a flowmeter serve each programme stage.

Integrated dispenser pumps

Two pumps dose liquid detergent and neutralising agent from the drawer. An external liquid dispensing system connection is available.

Door dispensers

Powder detergent and liquid surfactant each have a dispenser in the door.

Hot-air drying

A 0.3 kW fan and a 1.8 kW heater give 55 m³/h of air at 50 to 99°C for 1 to 99 minutes.

Safety set

An electric door lock, an end-of-programme buzzer, programme continuation after a power outage and a waterproof system are fitted.

Aerosol steam condenser

The steam condenser handles the vapour from the hot cycle.

Serial and optical interfaces

The serial interface supports process documentation, and the optical interface serves service.

Certificates and approvals

The G 7883 CD holds DVGW and WRAS certificates, VDE and VDE-EMC test marks and an IP X1 rating.

The G 7883 CD suits laboratories that wash test tubes, pipettes and narrow-necked glasses by the hundred, and want each batch to finish with disinfection and drying in a single programme. A technician moves between routine, heavy and temperature-sensitive loads on the same control, and the two thermal disinfection programmes add disinfection to that routine. The supply drawer, integrated dispenser pumps and serial interface keep dosing and documentation inside the machine, which suits benches that run the washer through the whole working day. A 90 cm wide footprint lets the washer sit under a counter, and one batch holds 1,600 test tubes.
