glass test tubes - small

A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top, usually with a rounded U-shaped bottom. Test tubes are widely used by pharmacists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays. Their round bottom and straight sides minimize mass loss when pouring, make them easier to clean, and allow convenient monitoring of the contents. The long, narrow neck slows down the spreading of vapours and gases to the environment. Test tubes are usually held in special-purpose racks, Test tubes for physics and chemistry are usually made of glass for better resistance to heat and corrosive chemicals and longer life. Tubes made from expansion-resistant glasses, such as borosilicate glass, can be placed directly over a Bunsen burner flame.8 clear glass test tubes of varied capacity with 3 glass mixers sitting in a wooden stand.

Culture tubes for biology are usually made of clear plastic (such as polystyrene or polypropylene) by injection moulding and are often discarded after use.A clear plastic test tubepharmacy, test tubes, plastic, culture test tubes, moorabbin, bentleigh, cheltenham, polypropylene, laboratories

Glass tube attached capped with metal and with a green plastic coated copper wire attached to conduct electricity. The other end of the tube narrows and has a metal 'prod' attached. The tube as a nother tube inside it which includes a spring made of fine wire. A small amount of thick liquid is present between both tubes.laboratory, testing, graham hood

suction regulating deviceOf significance to AHNL as similar to equipment used by nursesLarge glass test tube, with rubber stopper with two holes in top. Through one hole is inserted a long hollow glass tube, through the other hole is inserted a plastic y connector. On one arm of y connector is a short length of orange rubber tubbing, to the other end of this tubing is another larger y connection, with another short length of orange rubber tubing, with a metal clamp attached to bottom. The test-tube is attached to a varnished wooden board by two metal brackets. At the base of the test tube is a small wooden shelf for protection. On this backboard is a marked gradient of 60 cms. Two instruction diagrams are attached. Old catalogue numbermedical equipment, surgical drainage, suction regulator, thoracic surgery
