This Babcock tester was used in the laboratory at the Kraft cheese factory, Allansford. When it was superseded it was passed to one of the users of the machine, Les O'Callaghan, president of the Warrnambool & District Historical Society who placed it in the historical society collection. In 2009 when the historical society premises were upgraded there was insufficient room to store the tester so it was donated to Cheese World Museum. The machine was used to test the butterfat content of milk. Prior to dairy factories coming into existence farmers made butter individually on farms. There was no need for milk testing until farmers supplied factories for payment. Payment was based on a gallon of milk weighing 10lbs (pounds) and this led to richer milk, containing a high degree of butterfat for use in buttermaking, being paid at the same rate as lesser quality milk. In 1890 Stephen Moulton Babcock, an American professor at the University of Wisconsin-Madison, developed a method of determining the amount of butterfat in milk, thus providing a standardised and fairer system for payment. Babcock Test Process 1. 18 grams of milk (17.6ml) was put into a test tube 2. The same amount of sulphuric acid was added 3. A centrifuge at 50ºC was rotated at more than 900 revs per minute 4. The fat floating on top of the liquid in the test tube was measured The Babcock Test provided fairer compensation to farmers and also helped produce a consistent product for consumers. It also allowed for selective breeding when dairy herd testing evolved. ‘The Babcock Test is so simple that it can be used by any careful person, and it is inexpensive to operate. From the very beginning it was so complete in every detail that no change has had to be made in it.’ (Babcock Test http://www.en.wikipedia.org/wki/Babcock_test 31 March 2009) Round green metal container with opening lid.

This is the MINJAH telephone exchange testing unit. The exchange was adjacent to the property of MINJAH which is situated near Hawkesdale in Western Victoria. The exchange operated between 1955 and 1985. The testing unit was used for detecting and testing faults in the telephone system. The keys along the front were called "Hospital Keys" and were used to give subscribers a temporary connection in the event of a break down. The telephone exchange was replaced by an automatic exchange.This is a good example of a manual telephone system in Western VictoriaThis is a rectangular polished wooden box with a telephone mechanism on the side connected by a hook.

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.
