Final answer:
Implements and instruments used in biological experiments should be sanitized after use to maintain aseptic conditions. This includes metal tools like loops and forceps, as well as glassware such as pipettes and culture tubes, which are generally sterilized using an autoclave.
Step-by-step explanation:
Implements and instruments shall be sanitized after use on biological materials such as bacterial cultures to maintain an aseptic work environment. To ensure this, all equipment and supplies used in experiments, including pipettes, culture tubes, and glassware, should be sterilized. This also applies to tools used for transferring media or bacteria, such as inoculating instruments (loops and needles) and pipettes for liquid transfer.
Technicians must employ safety measures by wearing protective coats, face protection, and cut-resistant gloves. In the case of contact with harmful substances, the skin should be washed with detergent and warm water, followed by a cleansing with 1 N NaOH or bleach. Furthermore, waste is to be incinerated or autoclaved in a strong basic solution to prevent the spread of contamination.
Metal tools like inoculating loops and forceps can be sterilized by heating them in a Bunsen burner or sterilizer. An autoclave is typically used for sterilizing more delicate items that can withstand high pressure and temperature, ensuring that all potential contaminants are destroyed.
