2 H AEMACYTOMETER, GLASS NEW

2 H AEMACYTOMETER, GLASS

These Bright-Line (Rhodium coated) glass Haemacytometers are designed
for accurate counting of cells in blood or other fluids, with one-piece glass
construction, an H-shaped moat to form two counting areas (plateaus) and a
“V” slash at the loading side of each plateau. Each plateau features enhanced
Neubauer rulings, the ruled surface being 0.1 mm below the cover glass,
limiting the volume of blood or fluid over a square mm to 0.1cu.mm and
over each of 400 squares (within the central square mm) to 0.00025 cu. mm.
Contact of the flat, polished cover glass surfaces with cover glass supports
produces an exact volume of fluid over the counting area. The difference in
surface tension characteristics between the metallic surface on the chamber
and the polished cover glass assures smooth capillarity for precise loading and
more even cell distribution.

Supplied as a double chamber with two cover glasses or a kit which includes
a double counting chamber, cover glasses and red and white pipettes, all in a
protective case.

Spare/replacement glass cover glasses are also available, as a pack of 2.

• Bright Line (Rhodium coated) counting chamber
• Improved Neubauer ruling pattern
• Cell Depth: 0.100 mm ±2 %
• Volume: 0.1 µL
To clean the counting chamber after use: remove the cover glass and clean
with water or a mild cleaning solution (e.g. 10% bleach solution). Dry the
counting chamber with a soft cloth/wipe, or rinse with acetone.

BEST Used to measure very small objects,
travelling microscopes allow a student to
SELLER obtain a very accurate and precise
measurement. Like a conventional microscope, a traveling
microscope has a head fitted with lenses which can be
used to magnify and focus on a small object. The head,
however, is mounted on a slider which can be moved
along a scale. With the object fixed in place, the head
can be manipulated to take measurements of the object
being studied. The Vernier scale is used, a very precise
type of scale utilized for scientific measurements because
of its extreme accuracy and ability to measure very small
increments.

3 H ALF LIFE SIMULATION
This pack of 500 x 10 mm plastic cubes is used to investigate and demonstrate
half-life. Each cube has one black face, the other faces all being yellow. The
cubes are thrown or scattered like dice and those which land with the black
face uppermost represent radioactive nuclei which have decayed. The black
upward facing cubes are then removed, the remaining cubes thrown again and
the process repeated. The removed cubes represent radioactive decay and a
decay curve can be plotted from the results.

4 R ADIOACTIVE HALF LIFE APPARATUS

Designed for teaching students about half life and radiation at key stage 4 and
A2 level physics this ionisation chamber system uses gas mantles in a standard
wash bottle to generate and contain radon gas so it does not present a risk of
thorium powder release, and the quantities of radon generated are well below
hazardous levels. If a few gas mantles are put into the was bottle, a small
quantity of radon-220 will collect in it, reaching equilibrium - as much decays
as escapes from the gas mantles. If the radon gas is puffed into an ionisation
chamber, the air will be ionised and a very small current will flow. The current
will be proportional to the radon-220 activity. If the current is plotted against
time, it will demonstrate the decay curve with a half-life of approximately
56 seconds. This unit is fully compliant with safety regulations and is supplied
with full instructions for use

N.B. This apparatus comes fully complete with 3 mantles and a wash bottle
with connectors.

5 P ROTACTINIUM GENERATOR

The Protactinium Generator is ideal for demonstrating radioactive decay. The
half life of the isotope is short enough that students can complete the decay
curve within a single lesson and is perfect for use with a datalogger and GM
tube sensor or a standard GM tube and counter.

The generator is completely sealed in a leak proof enclosure and consists of
uranyl nitrate and an organic solvent. These settle into two distinct layers but
when shaken together react and produce a short term burst of beta radiation
with a half life of the order of about 1 minute. This can be observed using a
GM Tube with either a counter or datalogger. The generator comes complete
with an SDS and has a recommended storage period of up to 8 years.

R ADIOACTIVE SOURCES
Radiation Film Badge Dosimeters are routinely used by workers to monitor
radiation exposure and these badges can be opened to show the different types
and thicknesses of filters contained within.

The badge has six filters:

• An open window which allows all incident radiation that can penetrate the
film wrapping to interact with the film. A thin plastic film which attenuates
beta radiation but passes all other radiations

• A thick plastic filter which passes all but the lowest energy photon radiation
and absorbs all but the highest beta radiation.

• A dural filter which progressively absorbs photon radiation at energies
below 65 keV as well as beta radiation.

• A tin/lead filter of a thickness which allows an energy independent dose
response of the film over the photon energy range 75 keV to 2 MeV.

• A cadmium lead filter where the capture of neutrons by cadmium produces
gamma rays which blacken the film thus enabling assessment of exposure to
neutrons.

Please note that these badges are not functional, and are supplied without film.
They are for demonstration purposes only.

3 E LECTRON DIFFRACTION TUBE 4 D EFLECTION E-M TUBE 3 ELECTRON DIFFRACTION TUBE

The electron diffraction tube illustrates the wave nature of electrons by allowing
observation of interference caused by a beam of electrons passing through a
polycrystalline graphite target on to a fluorescent screen. The wavelength of the
electrons can be calculated for various anode voltages from the radius of the
diffracted rings and the distance between the crystal layers in the graphite.

The electron diffraction tube is a highly evacuated tube with an electron gun
consisting of a pure tungsten heater filament and a cylindrical anode all
contained in a clear glass bulb. The electrons emitted by the heated cathode
are constrained to a narrow beam by an aperture and are then focussed by
means of an electron-optical system. The resulting tight, monochromatic beam
then passes through a micro-mesh nickel grating situated at the aperture of the
gun. Onto this grid, a thin layer of polycrystalline graphitised carbon has been
deposited by vaporisation. This layer affects the electrons in the beam much
like a diffraction grating. The result of this diffraction is seen in the form of an
BEST image comprising two concentric rings that become visible on the fluorescent
screen. A spot resulting from the un-deflected electron beam continues to be
SELLER visible at the centre of the rings. Also requires an EHT power supply.

In addition, it can also be used for quantitative determination of the specific
charge of an electron e/m.

Located inside a glass bulb with a neon residual gas atmosphere is an 2 F INE BEAM TUBE (NEON-FILLED) WITH CONNECTOR BASE
electron gun, which consists of an indirectly heated oxide cathode, a Wehnelt

of the electrons and a narrow, well-defined, luminescent beam is produced.
Incorporated measurement marks facilitate a parallax-free determination of
the diameter of the circular path of the beam deflected in the magnetic field.
The Fine Beam Tube is mounted on a base with coloured connectors. In order
to protect the tube, a protective circuit is built into the base, which shuts off any
voltage in excess of the base’s pre-set cut-off voltage. The protective circuit
prevents excessive voltages from damaging the heater filament and ensures a

6 Z INC PLATE FOR PHOTOELECTRIC EFFECT

This Zinc Plate can simply be placed on top of an existing electroscope plate to
allow demonstration of the Photoelectric Effect using UV light. The plate must
be cleaned on both sides before use, to remove any oxide etc., using wire
wool or emery paper. The zinc plate needs to be negatively charged for the
experiment to work. This can be done by rubbing a Perspex (acrylic), acetate or
polycarbonate rod (to charge it), then placing this close to the zinc plate on the
electroscope - BUT WITHOUT TOUCHING IT ON THE PLATE. The plate should
then be touched with a finger, the finger removed, followed by removal of the
charged rod. The gold leaf should then deflect outwards, as it has become
charged. The best UV light source to use is one with a quartz glass lamp
envelope. Dimensions: 50 x 50mm.

4 FUNFLYSTICK

T he FunFlyStick is an electrostatic wand which allows special aluminised Mylar
strip ‘flyers’ to be levitated.

Inside the wand is a tiny Van de Graaff generator, powered by 2 AA batteries
(not supplied). When the button is pressed, the internal motor turns and
generates an electrostatic charge at the end of the wand. When the end of the
wand touches one of the flyers, the flyer becomes electrostatically charged,
and assumes a three dimensional shape, due to the flyer repelling itself. The
charged flyer is also repelled by the wand and moving the wand below the
flyer will keep it floating in the air. As soon as the flyer touches another object,
it loses its charge and collapses. Touching it with the wand again will recharge
the flyer and it will spring into life again!

Comes complete with instructions and five flyers. Just add 2 x AA batteries!
Safe to use but should be used indoors only. Like all Van de Graaff generators,
occasional cleaning may be required. Replacement flyers are also available.
Dimensions (L): 480mm.

When a current flows through the coil an electro-magnetic field is produced.
This field attracts the iron armature whose end makes the contact, completing
the circuit and illuminating the lamp. When the current is switched off, the
contact will open again, switching the circuit off.

This current balance apparatus (BIL coil) consists of a printed circuit board coil
mounted on a support handle. The board has 2 coils – one with 5 turns and
one with 10 turns, rated at 2A. The apparatus can be used to measure the
force on a current carrying conductor in a magnetic field. A permanent magnet
should be placed on the pan of a digital balance (a yoke with 2 ceramic
magnets will work) and the BIL coil mounted in a vertical plane between the
magnets. When connected to a low voltage power supply and ammeter, the
balance will be deflected and the new reading can be taken. The force on a
current carrying conductor and field strength can then be calculated.

8 MAGNETIC FIELD VIEWING FILM

5 P LOTTING COMPASS 6 P OCKET COMPASS This amazing flexible sheet ‘visualizes’ the direction of magnetic field lines. The
sheet is coated with translucent microspheres (hollow capsules) containing very
small magnetic nickel flakes suspended in an oil. The flakes inside the spheres
align along the field lines when a magnetic field is present. The alignment
of the flakes, and thereby the magnetic field direction, is visible because of
reflected light from the flakes. Useful for quality control, product demonstration,
reverse engineering, and educational purposes.

Two types and sizes are available: laminated and non-laminated ‘raw’ film.
The laminated film is ideal for student use as it is more durable and less easy
to damage. The non-laminated film is great for demonstration purposes as it
can be cut to any size or shape as required, is highly flexible and can easily be
wrapped around objects. A good example is to wrap it around a copper tube
to ‘view’ the progress of a neodymium magnet as it slowly descends through
the tube.

The film is also useful for viewing complex magnetic pole geometry close to the
magnetic poles, although it does require fairly strong magnetic fields.

GAUSS GUNS

4 MAGNETIC ACCELERATOR KIT (GAUSS GUN)

The gauss gun (also known as a gaussian gun or rifle) is an example of a
magnetic linear accelerator and uses powerful neodymium magnets to launch
a steel sphere at high speed.

Magnets are held in place part way along the tube (using the steel washers
provided), with two steel spheres on the ‘downhill’ side. Another sphere is
rolled slowly towards the magnets and as it gets closer the magnetic attraction
causes the sphere to accelerate considerably, resulting in the sphere impacting
with the magnets, transferring energy to the sphere at the opposite end of the
magnets causing it to shoot off at high speed (similar to how Newton’s cradle
works). Even faster speeds can be achieved by using a series of magnets
and spheres.

The magnets and steel spheres are contained within a clear plastic tube for
safety reasons (neodymium magnets are brittle and can splinter, the spheres
can be accelerated with some force). Kit includes 6 magnets and 5 steel
spheres, washers and clear plastic tube with rubber end stopper to stop sphere.
Instructions for use included.

MA110901 £36.46 kit

5 M INI GAUSSIAN GUN KIT

This simple ‘magnetic accelerator’ consists of a sloping plastic channel which
supports a row of 4 ball bearings, with a pair of neodymium magnets at the
end of the row to hold all the ball bearings together magnetically. Very slowly,
you roll the loose ball bearing towards the magnets. As it gets close to the
magnets, the ball bearing and magnets are pulled together very rapidly, due
to the magnets being so strong. As a result, rather like the Newton’s Cradle
apparatus, the ball bearing at the other end shoots off, at a surprisingly high
velocity.

Not suitable for unsupervised younger children.

MA120100 £12.34 kit

6 G AUSS GUN

This demonstration of the Gauss gun effect uses a 660 mm long section of
acrylic tube to house rare earth (neodymium) magnets and ball bearings. One
end is raised slightly to allow the first ball to begin its movement and there is
a rubber stopper at the other end to prevent the ball bearings from flying out.
The Gauss Gun demonstrates acceleration of a body in a magnetic field and
the conservation of momentum, using neodymium magnets to accelerate ball
bearings. The moving components are safely enclosed in a clear plastic tube.
This apparatus provides great discussion points on the nature and strength of
magnetic fields, momentum, conservation of energy etc.
