Physics
Snell’s Law
Spouting
Cylinder
An apparatus for demonstrating
the principle of Snell’s Law,
which states that pressure
increases with depth.
Liquid will exit from the 3 spouts
and travel further horizontally
depending on the depth of liquid
above them.
• 60mm diameter acrylic pipe
• 400mm total height
• 3 spouts at predetermined
heights
• Eisco type PH0196
Equality
of Liquids
Apparatus/
Pascal’s Law
Syringe
An apparatus consisting of a glass
flask with holes in the bulbous part
and a glass piston that slides in the
straight part.
When filled with liquid, the piston is
pushed into the apparatus, causing
liquid to exit each hole with equal
pressure regardless of the hole’s
position or direction.
• Also known as Pascal’s Law
syringe
• Eisco type PH0194
75mm Brass
Magdeburg
Hemisphere Set
A practical vacuum and
atmospheric pressure
demonstration set consisting
of two 75mm diameter brass
hemispheres.
Each hemisphere has a handle firmly attached
to it. One of the hemispheres has a stopcock
for attaching to vacuum tubing. When the
hemispheres are pushed together and evacuated
using a vacuum pump they are hard to pull apart.
Get 2 students to pull, then open the stopcock to
let air in and the hemispheres will separate easily
to the surprise of the students.
• Made of brass
• Fitted with stopcock
• Diameter 75mm
• Eisco type PH0172
Vacuum Pump Plate
This pump plate has been manufactured from aluminium and has
a tube for connection to a vacuum pump and a stopcock for air
regulation.
The plate is mounted on a heavy, painted tripod base for good
stability and is supplied with a rubber seal which facilitates sealing in
experiments involving bell jars.
• Diameter 250mm
• Tripod-style base for stability
• Suitable for many physics experiments involving a vacuum
• Eisco type PH0156C
Hand-Powered
Vacuum Pump
This economical vacuum pump features a
gauge graduated in both cm³ and inches³. Each
depression of the handle displaces 15ml of air.
• Economical vacuum pump
• Gauge in cm³ and inches³
• Maximum vacuum 50mm of Hg
• Can also produce positive pressures up to 2atm
• Pump rate 15ml per stroke
• Clear tubing is 600mm long with 6mm inner
diameter
• Eisco type PH0167
Jolly Bulb with Gauge
This Jolly bulb apparatus consists of a 60mm diameter
bulb directly connected to a bourdon pressure gauge.
The apparatus is used for investigation of gas at a
constant volume. By inserting the glass bulb into either
warm or cold water, the expansion or contraction of
the air contained in the bulb can be seen as a pressure
change on the gauge.
• 60mm diameter glass bulb
• Gauge calibrated in both kg/cm² and in psi
• Eisco type PH0138C
