STATEMENT OF WORK

1. Objective/Requirements

We request to procure a new autoclave that will sterilization of lab supplies, media and seawater used for growing algae. This procurement is for a Yamamoto Scientific America Inc. model SM820 autoclave, sterilizer and dryer. The Steris autoclave used in Bldg 22 Rm C287 for the past 20 years was no longer functioning and cost prohibitive to repair and was thus excessed. A replacement unit is required to retain those capabilities. The Yamamoto autoclave provides a large capacity internal chamber (80 Liter) to sterilize laboratory materials, media and seawater used to culture algae for laboratory experiments. The unit is compact and meets our requirements for space availability of 21 inches x 27 inches of floor space and is low height (~3 ft) for ease of loading and unloading.

2. Characteristics, Scope, and Specs

Yamamot Scientific America, Inc.

Model: SM820

Standard and required Features:

80 L capacity (large capacity for price point compared to other brands/models) small floor footprint <21 inches by <27 inches (520 x 660 millimeter actual) low height (~3 ft; 1161 millimeter actual) to facilitate loading and unloading;

fully automatic sterilization from start to finish with high pressure steam sterilization and drying steps; interactive keypad input (touch panel) allows committing sterilization settings (time & temperature) to memory;

easy settings and operation modes for a multitude of sterilization process;

7 inch touch screen panel increased safety and function list including forced cooling and memory functions;

equipped with multiple safety locking mechanism for the lid.

Equipped with cooling fan starts after sterilization operation to cool down to safe temperature, which is time saving Safety devices: Sterilize sensor error, sterilize SSR short circuit, dry sensor error, dry SSR short circuit, sterilize heater disconnection, dry heater disconnection, water level detection (liquid expansion method), independent chamber overheat protection, cover unlock error, chamber over pressure protection, under pressure protection, warning about setting error in cooling water container, memory error, pressure switch (0.25MPa), pressure safety valve (0.255MPa)
