| 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.

| BURETTE WASHER SET: BASKET 648mm (H) x 145 Dia. | This sturdy plastic basket unit holds burettes (and pipettes) up to 600 mm long for easy soaking and cleaning. lndispensable in the laboratory where radioactive, caustic and toxic materials are in use. The polyethylene rinser fills via the spray nozzle situated on the top rim. This eliminiates backsyphoning as the water inlet is located above and away from any contaminated waters. Contaminated waters will syphon out totally, once the syphon point at the top of the rinser has been reached, via the large diameter drain situated at lowest point, before refilling automatically. These specially designed baskets help minimise breakages as it buffers the tips of pipettes against the soft polyethylene during the washing process. Since soaking takes the longest time, two or three baskets pipettes/burettes can soak in their jars whilst another basket full is being washed in the rinser. Low water flow rate is NOT A problem but it is better to adjust the flow for A cycle of about 90 secs.* This item is part of A basic BURETTE WASHER SET: . Code: GSKAR219.
