LABORATORY WASHING AND STERILIZING EQUIPMENT

PART 1 - GENERAL

1.1 DESCRIPTIONS

This section specifies Laboratory Washing and Ster ilization Equipment including laboratory glassware and utensil washers, steam sterilizers, drying ovens, cage and cart washers, animal water b ottle washers/fillers, animal cage and rack washers, anim al bedding dispensers, animal bedding disposal equipment, glas sware dryers, ice machines, exhaust hoods, flushing rack systems, ste am guns, instrument washer, detergent dispensing units, and water purif ication systems.

1.2 DEFINITIONS

A. Glassware and Utensil Washer: An automated washi ng unit that uses high-temperature water and detergent to clean and disinf ect instruments and lab glassware.

1. Under-counter Model – Single chamber washer/disi nfector.

2. Counter-top Model – Single chamber washer/disinf ector.

3. Free standing Model – Multiple chamber washer/di sinfector.

B. Steam Sterilizer: A machine used to sterilize in struments and equipment by subjecting them to high-pressure steam up to 135 °C (275°F).

Sterilizers are available in both cart-loading and counter-top models.

They can be either freestanding or recessed, with s ingle or double doors (pass-thru). Steam sterilizers are also known as autoclaves.

More efficient models employ a vacuum pump to remov e air from the chamber prior to a sterilization cycle, thus provid ing more efficient steam sterilization. In animal facilities or other high throughout environments, autoclaves with very large floor-leve l chambers capable of accepting “roll-in” racks of cages or other item s may be needed.

D. Utensil & Cart Washer: An automated washing unit that uses high-temperature water and detergent to clean and high-l evel disinfect cages, utensils and carts. Units are generally larg e enough to readily roll entire racks or carts directly into the washin g chamber.

F. Counter-top Sterilizer: A counter top mounted or free-standing machine used to sterilize instruments.

J. Exhaust Hood: Exhaust canopy hood for venting he at, steam, moist air, and odors. Frequently placed over autoclave doors and entry/exit

VA Project # 568-16-101 11 71 02 - 2 locations on other equipment when moisture or steam is expected to enter the environment from the equipment.

L. Steam Gun: Hand held hose and high pressure stea m spray wand used in manually washing cages, carts, and other large cont ainers.

O. Detergent Dispensing System: A mechanical system that dispenses measured doses of detergent or other chemicals dire ctly to washer disinfectors and cart washers.

P. Water Treatment System: A mechanical system for use with steam sterilizers, washer/disinfectors and cart washers, that decreases contaminates in the domestic water to reduce boiler scaling and instrument spotting.

S. Chlorine Injector Station: For automatically inj ecting chlorine into water used for Recoil Hose Flush Stations, Reverse Osmosis Systems, and other applications.

U. Central Compressed Air System: A system to provi de ‘oil free’ and contaminate free compressed to equipment where comp ressed air is an optional feature.
