PROF BUNSEN (EF) - VACUUM STOPPER (Pack of 10)
Forget about vacuum demonstrations requiring expensive vacuum pumps and glassware. Students can now perform A number of exciting investigations right at their work stations for the fraction of the costs. Our unique rubber stopper will block airflow to A plastic or gas syringe tip so when the plunger is extracted, A vacuum is created. Students can then easily: - expand A small balloon under reduced pressure; - boil water at 70deg C and understand while boiling water up A mountain is A problem; - watch A marshmallow & shaving cream expand and more. Syringes or gas syringes are available in 1ml, 3ml, 10ml, 20ml, & 50ml. Code: PBSF28. Suppliers to schools & laboratories of science equipment & laboratory grade chemicals.

BOYLE'S LAW APPARATUS - PHILIP HARRIS
Horizontal mount: This apparatus consists of A horizontally mounted acrylic tube with A graduated scale along one side (scale graduated from 0 to 300cm3). The tube unit is sealed by A standard gas tap next to which is mounted A standard pressure gauge. The effective length of the tube is controlled by altering the position of A rubber stopper moved via A screw thread. Users can select the effective length of the tube by positioning the stopper and closing the gas tap. The volume of the tube can be read off the scale and printed against the corresponding pressure taken from the gauge. By varying the position of the stopper Boyles Law can be investigated. This unit has the advantage over earlier models of not requiring oil to indicate the volume of air. Code: L71663. Suppliers to schools & laboratories of science equipment & laboratory grade chemicals.

FLOAT COLD / SINK HOT OBJECT
Studies the effect of temperature on the density of A liquid. A carefully counterweighted 75mm diameter copper ball will just float in cold water but sinks in hot water due to the subtle difference in water density. Is fitted with A stopper to enable ballast weight to be altered. Demonstrates the principle of Galileos Thermometer. Made in U.S.A. Code: TSS32260.

PROF BUNSEN (EF) - AIR & WATER PRESSURE KIT
Use the large cylinder and piston with the syringe and tube to investigate the compression of air and water. A number of experiments are possible from the included worksheet but the best is the making of an air gun to launch safe foam stoppers across the room (Boyle's law). Or use potato projectiles! Can be used with A pressure gauge to verify Boyles Law. The hand safety guard is very functional. Code: PBSF38. Suppliers to schools & laboratories of science equipment & laboratory grade chemicals.

PROF BUNSEN (EF) - WATER ROCKET LAUNCHER
An empty soft drink bottle is filled with water and positioned over the rubber stopper on the launch pad. The car tyre pump compresses the air in the bottle and ... the stopper releases the bottle up to 30 meters or more. The pre-assembled launcher has an adjustable rubber stopper in order to adjust the pressure build-up (and eventual altitude) before launch. Experiment with double bottle rockets and fins! Prof Bunsens extension ideas included. Required: Car tyre pump, plastic soft drink bottles (any size) Age: 10+ with adult supervision. Warning: High pressure build-ups are achieved. Code: PBSR09.
