These usually require light lubrication, using Silicone grease. PTFE key stopcocks are now the most frequently used because they do not need any lubrication, are less likely to jam than glass stopcocks, and are regarded as a lower maintenance option. Modular PTFE key stopcocks are made entirely of PTFE and are particularly suitable for schools as they are less delicate than the other types and all of the parts are replaceable separately. ‘Rotaflo’ type burettes have a screw in/out PTFE key which allows for fine drop control. Types of Graduation Different colour graduations can be useful, depending on the colour of the solution being titrated. Blue graduations – good for general purpose use.

CHEMISTRY Electrolysis Voltameters A voltameter is an instrument for measuring the quantity of electricity (i.e. the amount of electric charge). This is done by measuring the amount of element deposited or released at the cathode. In schools, they are typically used to demonstrate the composition of water being two parts hydrogen to one part oxygen. Student Gas Voltameter Hofmann Voltameter For student experiments. Embedded platinum electrodes are connected Comprises three parallel tubes, joined at the bottom with a horizontal via 4mm sockets. Two miniature test tubes are included for gas tube. The central tube has a funnel for filling with water, and the side collection. tubes have open ends at the bottom to allow bungs that hold electrodes to be fitted, and jets with stopcocks at the top for collecting gas in test tubes. The side tubes are graduated 0-50 x0.2 mL so that the volume of gas in each can be measured. Clamps and support base (sold separately) are recommended so the unit can be mounted on a retort rod.

A cheaper alternative is to use nichrome wire, (salt) which works well but tends to give a trace of orange colour in Barium Pale green / green a flame. Boron Green / bright green Caesium Blue / violet It is more effective to use a flame test wire with a loop at the Calcium Orange-red / brick red end, as this allows more of the sample being tested to adhere Blue-green / green or blue to the wire. Copper (depending on which ion) Blue Wires should be cleaned first by dipping the end or loop into Indium Yellow-gold concentrated hydrochloric acid (HCl) and then placing in a hot Iron Grey-white (blue) Bunsen burner flame. This process should be repeated Lead Red / crimson until no colour comes off the wire in the flame. Concentrated Lithium Light green / yellow green acid works best but diluted HCl can be used instead, although Manganese Lilac / pink / violet less effectively, if safety issues are a concern – the flame Potassium Red / red-violet colours may not be so intense. Rubidium Orange / orange-yellow Sodium Red Then the end of the wire or loop should be moistened again Strontium Green in the acid, dipped into the sample being tested (so that some Thallium Blue-green sticks) and placed back into the Bunsen flame. Zinc The table lists typical flame test colours for various metal compounds (salts). Please be aware that this is only a guide and colours may vary from sample to sample, depending on the source and purity. +44 (0) 3333 442 443 [email protected] timstar.com 197
CHEMISTRY Gas Bottled Gas Miniflow Regulator Bottled Gas, Mini, Non-Refillable For use with 34 and 110 litre canisters. The most economical solution for controlling the Compressed gas in small, economical bottles. Ideal for low gas volume flow of gas (0.5 - 1.5L / minute) from these requirements. Bottles require a control valve, which is interchangeable canisters. It allows the user to adjust the flow between bottles of different gases and are non-refillable (disposable). of gas. Bottles are re-sealable and valve can be removed whilst gas is still in the bottle. Dimensions: 270 x 75 mm.

It allows the user to achieve GA110140 Carbon dioxide 14 litres £48.69 ea a fixed flow of gas (0.5litres / minute) and Hydrogen 14 litres features the added benefit of a pressure Helium 14 litres gauge indicating the contents of the canister. Valve for Mini Gas Bottles Screw-on fine control valve for mini gas bottles (only). The valve is interchangeable between bottles of different gases. GA110145 £36.81 ea GA92034 £137.50 ea Bottled Gas, Non-Refillable Balloon Regulator A special regulator designed specifically for filling balloons from the 34 and 110 litre canisters. It features a balloon adaptor which prevents the escape of gas during the filling process. GA92004 Type Capacity £124.94 ea GA92038 £156.25 ea GA92005 £181.25 ea GA92006 Carbon Dioxide 34 litres £114.94 ea GA92007 Carbon Dioxide 110 litres £187.50 ea Hydrogen 34 litres Hydrogen 110 litres Please note: For all bottled gases, the volume of gas stated for each cylinder is the volume the gas will occupy at atmospheric pressure. For example, a 34 litre cylinder has an actual (water) volume of approximately 1€litre, due to the gas being so compressed and a 110€litre cylinder has an actual cylinder volume of approximately 1.6 litres. If using the bottled gases to fill rubber or latex balloons, due to the surprisingly large volume of a balloon (e.g. a 9”/23cm spherical balloon would have a volume of approx. 6.3 litres) and also to the pressure the balloon walls exert on the gas, the number of balloons which can be filled will be considerably fewer than expected – probably only 3 or 4 from a 34 litre cylinder (depending on the size of balloon) and perhaps only 1 from a 14 litre bottle. 198 More products and offers available on our website!
