In hard water areas deionising cartridges will not last long before the resin under high water pressure becomes exhausted, so this would not be a very cost-effective way to produce purified water. • RO can also be used in conjunction with a deioniser to produce very pure water. An added benefit of using RO as the first stage of the process is that deioniser cartridges (resins) last much longer, due to most of the impurities having been removed before reaching the deioniser - the resin therefore becomes exhausted less quickly 106 …inspiring tomorrow’s scientists through practical science.

A cell (also called electrolytic cell or voltaic cell) is a device which has two electrodes in an electrolyte, producing electricity by electrochemical reaction. The output is a smooth direct current/voltage (dc). A battery consists of two or more electrolytic cells which are connected together to function as a single unit to give a higher dc voltage or current output (higher current when connected in parallel, higher voltage when connected in series). NON-RECHARGEABLE BATTERIES These are single-use only. Also known as primary cells or Leclanché cells, with a gel type electrolyte. Mostly used in devices which have a low current requirement although alkaline types can be used for both low current drain & high drain devices. Voltage is typically 1.5V from a single cell. Voltage falls steadily during use. TYPES Zinc-Carbon (ZnC) – These are usually the cheapest but have the shortest life during use. Zinc-Chloride (ZnCl) – Similar to ZnC but with a slightly longer life. Alkaline – These have the longest life and can also be used for high drain applications (e.g. cameras). Silver oxide button cells – These give a steady voltage discharge over a longer period before it drops off, with a longer operating life than the alkaline equivalents. Alkaline button cells – The voltage drops below the nominal quicker than with Silver oxide cells. They are cheaper but have a shorter life during use. Lithium coin cells – These have a high energy capacity to mass ratio and produce a higher voltage per cell – typically 3V. RECHARGEABLE BATTERIES Also known as secondary cells or accumulators. Voltage remains fairly constant during use until nearly exhausted, when it falls rapidly. Voltage is typically 1.2V from a single cell - due to the chemistry involved this is the limiting factor. TYPES Nickel Cadmium (NiCd) – These are an older type, now replaced by NiMH types. They tend to suffer from ‘memory effect’. Nickel Metal Hydride (NiMH) – The universally used type of rechargeable cells & batteries for general use. Memory effect is not really a problem. NOTE: Both NiCd and NiMH types self-discharge during storage due to the nature of their chemical and physical properties so it is always worth recharging again before use if stored or unused even for short periods. ‘ReCyko’ – This is a brand name of a newer type of NiMH rechargeable cells & batteries, which arrive fully charged and will not discharge as readily as normal NiMH types. They should retain up to 85% of their charge when stored for a year – far more than standard NiMH cells & batteries. Lithium-ion – These have a high energy capacity to mass ratio and no memory effect. Often used in laptops, digital cameras, camcorders and other portable devices. They do not readily self-discharge and give a higher voltage per cell – typically 3.6V. Lead-acid – These are ‘wet cells’ but more recently ‘gel cells’ where the electrolyte is either liquid or gel. Usually used for vehicle batteries and alarms and are able to deliver a high current, although they are usually larger and heavier than other types of battery, for the same voltage rating. AMP HOURS Rechargeable batteries usually have the capacity specified in milli-Amp hours (mAh) or Amp hours (Ah). This is the amount of current the battery should be able to supply in one hour. For example a battery rated at 2300mAh should be able to supply 2300mA for one hour. Of course if the current drain of the device being powered is lower or higher, the battery life (discharge time) will be longer or shorter. 110 …inspiring tomorrow’s scientists through practical science.

Chargers & Testers BATTERIES Battery Tester, Professional This professional type battery tester, made by Ansmann, gives a true indication of the capacity of a whole range of commonly used battery types. Not only does it give a voltage reading but also indicates the remaining battery capacity as a percentage relative to full capacity (100%). Most simpler battery testers will only indicate the voltage of a battery without a load connected (i.e. not powering a circuit), which can often be misleading as once a load is connected the voltage can drop very quickly if the battery capacity is low - even though the voltage reading may have been fine. The Ansmann professional tester eliminates this possibility, giving a reliable indication of the actual capacity of the battery being tested. The tester can be used to test: Alkaline, Lithium photo, Lithium button, Zinc-Air, NiCd, NiMH battery types including all commonly used 1.5 V alkaline cells (AAA, AA, C, D), 9 V PP3, 1.5 V button cells, 3 V Lithium coin cells, 3 V Lithium photo batteries, 6 V Lithium photo batteries, 12 V alkaline (A23), 1.44 V Zinc- Air and 1.2 V NiCd and NiMH rechargeable batteries (AAA, AA, C, D). Simply place the battery onto the tester and check the reading, or connect the probe to one end of the battery cell then check the reading (depending on type being tested). The LCD indicates Voltage along with battery capacity in 10% steps and includes a self-test button to test the internal battery capacity. Includes 9 V PP3 battery, test probe, instructions and two year warranty.

BIOLOGY Biotechnology, Electrophoresis & PCR Introduction to Biotechnology Genetics & DNA Kit See genetic material with your own eyes as you isolate the DNA from a tomato in a test tube. Investigate inheritance and learn how traits are passed down from parents to children. Learn about dominant and recessive genes and play inheritance games to determine how traits will be expressed. Learn about the biology of reproduction, the components of cells, and how chromosomes are combined and copied. Assemble a model to see the elegant double-stranded helical structure of DNA. Then crack the genetic code and find out how the different parts, called nucleotides, fit together. Analyze DNA evidence to identify suspects and solve a crime. Breed your own bacteria colony to experiment with survival of the fittest. Read about how mutation affects genes and how scientists clone plants and animals. Head into the lab for an in-depth investigation of genetics, the branch of biology focused on heredity and variation in organisms, and DNA, the acid that holds the blueprints for life. Complete with 48-page colour manual. Contents: Wooden skewer Petri dishes (2) Glass bottle Test tubes (2) Plastic chips (12) LB nutrient agar Funnel Inheritance chart Wooden spatula Filter papers (10) Cell poster Safety goggles Pipette Chromosome puzzle Measuring cup DNA model BT140105 £31.19 kit The following tables are a summary of each particular sub-section in this section.
