These positions are also known by other names such as laboratory support worker, clean room technician, cleaning technician, glasswasher, laboratory helper, laboratory aide, and equipment preparation technician. Generally only a high school diploma is required but an individual with a two-year degree will most likely advance-up in the company; therefore this position is commonly seen as an entry-level position. These positions may involve the following activities; washing, drying and sterilizing glassware and other items; testing the items to ensure sterility; maintaining the inventory of glassware and other similar items; maintaining a clean room; and ordering items. The work is somewhat redundant, however it is viewed as being very important as clean, sterile glassware is needed throughout a biotechnology company and there can be no room for error in the preparation of glassware or similar equipment. Most positions are full time, 40 hours per week, Monday to Friday. Some part-time or shift work may also be available.
