Laboratory glassware washers rely on a number of interactions. The mechanical action of the water creates a scrubbing effect, while the detergent chemically reacts with the contaminants to fully cleanse glassware. Other factors include water temperature and time. Proper water temperature is used to aid the chemical reactions, while sufficient time is required to complete the chemical reactions.

The two basic types of lab glassware washers are undercounter and freestanding. Undercounter washers fit under the counter, usually next to sinks or a washing station. Some undercounter models also fit in confined cabinet spaces. Freestanding washers are often larger units that cannot fit under the counter and have a higher capacity. While undercounter washers are mostly installed at individual labs, freestanding units are also found in centralized core washing facilities.

Even though lab washers have been around for decades, the recent years have brought technological advancement. Regulatory changes have given rise to an array of electronic connectivity options, including serial connections, Ethernet and wireless. Environmental concerns have pushed the vendors to integrate more green technologies, including recyclable materials, lower water usage, and more environmentally friendly washing reagents and chemicals.

Miele is the leading laboratory glassware washer manufacturer and has a particularly strong market share in Europe. The company has washers for all types of laboratories, ranging from basic systems designed for classrooms to more sophisticated units installed in biotechnology and pharmaceutical labs. Miele’s PG 85 series washers are the company’s top-end units. The series come in a variety of configurations and capacities and can produce documentation via Ethernet or RS232 interface.

Lancer is another major manufacturer of lab glassware washers, with both undercounter and freestanding offerings. The company makes three models of undercounter glassware washers and five freestanding models. All of Lancer’s washers can be configured with a RS232 port for data transfer. Its largest model, the 1800 LXA freestanding glassware washer, is a dual-chamber unit that can wash and dry thousands of glassware per day.

Labconco also has a large line of lab glassware washer systems and an extensive line of accessories. Labconco’s washers are offered through two product lines: StreamScrubber and FlaskScrubber. Both lines offer multiple models for undercounter and freestanding use. Other vendors manufacturing lab glassware washers include STERIS, SP Scientific, Getinge and SMEG Instruments.

The market for lab glassware washers is approaching $100 million. While the market is expected to grow at a moderate rate, applications in pharmaceuticals, biotechnology and forensics are driving growth. Lab expansions and replacement sales as a result of regulatory changes are expected to fuel future growth.
