Caption:
This image, dated 1979, presents two Erlenmeyer vacuum flasks, also referred to as conical or titration flasks, coupled together with rubber tubing. The hands of a laboratory technician are shown holding the end of the tubing, which is fitted with a narrow glass pipette nozzle inserted into a conical-bottom test tube with a threaded neck. The bottom of the test tube contains an unidentified red substance, above which rests a clear, colorless supernatant that is being drawn into the pipette. The nature and purpose of the procedure are not identified. Contemporary laboratory protocols require the use of personal protective equipment (PPE), including protective disposable gloves in a scenario such as this one.
