PURIFIED WATER FOR USE IN LABORATORIES
Purified water for use in school science laboratories is essentially Distilled Water
water which has had inorganic impurities removed to varying degrees,
depending on the method, producing what is often called demineralised • Salts and minerals are removed by boiling tap water in a water-still
water. The most commonly used types of purified water in school
laboratories and prep rooms are as follows: and re-condensing the vapour (steam) produced, leaving dissolved
minerals/salts behind.
Deionised Water
• Water stills can be expensive to run (electrically) but produce much
• Charged ions are removed in a deioniser containing ion-exchange
larger quantities of purified water than deionisers before replacement
resins, which consist of small resin beads composed of organic polymer parts may be needed (heating element for stills, resin cartridges for
chains with charged functional groups. These remove charged anions deionisers).
and cations from water as it passes over them.
Reverse Osmosis (RO) Purified Water
• Life expectancy of deionising cartridges depends on water hardness,
• Removes minerals/salts from water using a semi-permeable membrane
purity of the tap water and volume of deionised water produced. 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

The high quality PYREX® borosilicate glassware coupled with silica sheathed
heaters gives pyrogen-free distillate of the highest purity from virtually any raw
water supply.
The boiler feed is pre-heated to increase efficiency. The unique condenser
design ensures that the droplets of distilled water remain in contact with the
cooling coil for the longest possible time ensuring maximum energy transfer.
All-glass construction allows rapid descaling using strong mineral acids. A
built- in “clean” function and integral acid addition funnel make the cleaning
operation simple and safe with no need to dismantle any of the glassware.
A large bore ROTAFLO® stopcock with PTFE key is fitted for easy draining of
chemicals after cleaning.
A flow sensing device prevents overheating, and allows the unit to run on water
supplies with a pressure as low as 3 psi (20 kPa). There is an over-temperature
thermostat mounted in the boiling chamber as an additional fail-safe.
The acrylic safety screen and the cabinet lid are removable giving easy access
to the glassware components. Screw threads are incorporated on all water
connections so hoses can be fitted and removed easily and safely without risk
of breakage.
The control is a simple and effective system which can be fitted to virtually any
type of reservoir vessel. It will turn the still off when the reservoir is full, and
restart it when the level in the reservoir drops, making it fully automatic.

CELL OR BATTERY?
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.

2 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 1.5V alkaline cells
(AAA, AA, C, D), 9V PP3, 1.5V button cells, 3V Lithium coin cells, 3V Lithium
photo batteries, 6V Lithium photo batteries, 12V alkaline (A23), 1.44V Zinc-Air
and 1.2V NiCd and NiMH rechargeable betteries (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 9V
PP3 battery, test probe, instructions and two year warranty.

RECYCLING BATTERIES INFO
PRODUCT
5 BATTERY SNAPS Please consider recycling your old batteries
when finished with or no longer required. Many
batteries contain chemicals that are harmful to
the environment when not dealt with correctly. The
discarding of batteries in refuse bins means they
will end up in landfill sites, causing pollution.
Many shops and supermarkets, as well as council
recycling points and waste disposal sites, have a
battery collection point.
All battery types sold by Timstar can be recycled (both rechargeable
and non-rechargeable as well as button cells), as can battery packs
from electronic and electrical equipment. It doesn’t matter if the
batteries are full, completely discharged or part used.

2 MODELLING MINI-TOOBERS 1 A MINO ACID STARTER KIT
3 B ETA GLOBIN FOLDING KIT Explore the primary, secondary and tertiary structure of proteins with the
captivating models and tools in this dynamic kit. Students learn the chemical
properties of the 20 amino acid side-chains with dynamic, accurate, side-chain
models featuring embedded magnets in a durable plastic. Side-chains feature
dual colouring schemes - a coloured band at the base of each side-chain
indicates chemical properties, while embedded coloured balls in the model
show atomic structure. Understanding protein structure begins with this unique
combination of structure and chemical properties of the amino acid side-
chains. Through the kit’s engaging hands-on activities, students gain a basic
knowledge of protein folding. Then they discover the importance of secondary
structure with an additional folding activity.
Each kit includes: 1 magnetic chemical properties circle, 1 amino acid side-
chains list, 22 amino acids, 1 4-foot Mini-Toober (a flexible foam modelling
rod with a soft wire core), 15 metal clips and 6 hydrogen bond connectors, a
CD with teacher notes, student hand-outs and interactive Jmol visualisation
(an open-source Java viewer for chemical structures in 3D). The 3 group kit

DNA MODELS
4 N UCLEOSOME MINI MODEL
The nucleosome is the most basic, repeating structural unit of chromosomes.
Its central protein core has 8 histones (2 copies each of NH-2tAer,mHi2nBa,lHe3ndanodf
H4) and 145 base pairs of double-stranded DNA. The
each histone has many positively-charged amino acids that interact with the
negatively-charged phosphate backbone of DNA. This model reveals that
histones interact only with the minor groove of DNA. The major groove is then
available for sequence-specific DNA binding proteins, such as Zif 268. Mini
Models are made of plaster by rapid prototyping and should be handled with
care.
