G 7883: The Ultimate Solution for Laboratory Glassware Cleaning

The Miele G 7883 under-counter glassware washer is designed to meet the demanding needs of modern laboratories. With the increasing precision required in research, the G 7883 ensures that glassware is consistently cleaned to the highest standards. Its advanced features, including a multitronic control system and customizable wash programs, make it an ideal choice for diverse applications, from trace metal analysis in water treatment facilities to tissue culture in university laboratories.

The G 7883 is engineered to deliver outstanding cleaning performance through a delicate balance of wash time, water temperature, water circulation, and detergents. This ensures thorough and consistent results with every cycle. With eight pre-set wash programs and one customizable slot, the washer can adapt to various laboratory cleaning requirements. The ability to adjust the wash and rinse temperatures up to 93°C enhances cleaning efficacy, setting it apart from standard machines that typically max out at 60°C.

The high-flow circulation pump operates at 106 gallons per minute, nearly double that of other washers, ensuring effective water turnover while being gentle enough for delicate items. For added flexibility, the G 7883 comes equipped with separate pumps for circulation and drainage, minimizing cross-contamination risks and simplifying installation.

Constructed to withstand rigorous use in demanding environments, the G 7883 features a high-quality stainless steel interior and exterior. The wash chamber's walls, ceiling, and door are made from durable 304 and 316-grade stainless steel, providing exceptional corrosion resistance. The exterior is available in either stainless steel or an optional white finish, allowing users to match their lab’s aesthetic.

Miele's renowned craftsmanship ensures that seams are laser-welded external to the wash chamber, eliminating corrosion-prone areas and extending the washer's lifespan. This robust construction is complemented by advanced filtration systems to prevent debris from recirculating and to protect the pumps.

The G 7883’s multitronic controller offers easy-to-use programmable settings, allowing operators to configure wash times, water volumes, and temperatures precisely. The clear LCD screen displays key information such as the current program step, temperature, and time elapsed. Additionally, fault indicators alert users to any issues, helping to maintain optimal performance.

Automatic liquid dispensing is an optional feature that ensures accurate dosing of detergents, reducing the likelihood of user error. The system can support a liquid detergent reservoir, typically lasting up to 500 washes before requiring a refill, adding convenience and consistency to the cleaning process.

The G 7883 is designed for hassle-free installation and maintenance. It includes a built-in steam condenser, eliminating the need for external venting while removing potentially hazardous steam from the lab. The steam condenser uses cold water to condense and safely flush vapors down the drain, reducing ambient heat and improving the work environment.

The washer is also equipped with a built-in water softener, which improves cleaning results by preventing scale buildup. The system can be adjusted based on incoming water hardness or deactivated if the water supply is already soft.

Laboratories requiring machine validation will find the G 7883 well-suited to their needs. With an optional RS-232 connection for data logging and multiple sensors for accurate monitoring, the washer supports easy validation processes. Miele offers extensive validation services, including Installation Qualification (IQ) and Operational Qualification (OQ) documentation, as well as dedicated technical support for installation, maintenance, and application issues.

The G 7883 under-counter glassware washer by Miele is a reliable and flexible solution, offering superior cleaning performance, robust construction, and features that cater to the exacting standards of modern laboratories.
