Boyle's Law Apparatus
This low cost apparatus is great for demonstrating Boyle's Law,
(elasticity of gases. A plastic syringe is mounted on a wooden base. A
piston is mounted to a platform that holds various size weights, allowing
students to plot pressure versus volume of gases in the cylinder. 9"
x 6" x 2"
No. SF222-BA. Only $12.95
Pascal Vases
For demonstrating that the pressure of a liquid at the bottom of a vessel
is proportional to the depth of the liquid and is independent of the
volume and shape of the vessel. Consists of three borosilicate glass
vessels of different shapes, open at both ends, having ground edges and
bottom openings of equal size. Provided with plastic disks and
attached hooks and strings so that when vessels are immersed bottom down,
water pressure hold the disk in place. Used to show that the
depth of the vessel when water is poured inside is independent of the
shape of the vessel.
No. SF222-PV. Only $18.95
Pascal Ball
This device is used to show that water pressure will transmit in all
directions. consists of a hollow sphere connected to hand pump. The
sphere has an outer diameter of 3 inches and a capacity of 250ml. Ten
projected nozzles are evenly distributed on the sphere. For some extra
fun, stick balloons on them. Instruction manual included.

Both of the above are made of clear
glass. They have been colored to make them easier to see.
Venturi
Apparatus
For demonstrating Bernoulli's principal that any restriction in fluid flow
results in increased speed and decreased pressure. Comprised of a
borosilicate glass tube (8cm long and 18mm in diameter) with a
constriction in the centre and the three vertical openings in different
sections. Includes three glass manometer tubes and rubber connecting tubes
for measuring pressure at three locations. Ends are flared.
No. SF222-VA. Only $8.75
Pressure
Syringe
Demonstrates that liquid pressure is transmitted equally in all
directions. Consist of a borosilicate glass bulb (50mm diameter) with
holes. Filled with a piston for compressing liquids. Total
height is 250mm.
No. SF222-SY. Only $9.95 |

Open Manometer
A multiple-use manometer for accurate measurement of gas pressure.
Consists of a borosilicate glass manometer tube with a 50cm arm
having funnel top and a 25cm arm with riffle for each connection to
rubber tubing. Mounted on wooden board fixed to a wooden
stand.
No. SF222-MA. Only $17.95
Demonstration Manometer
For measuring the pressure of gases. Suitable for moderate
pressures. Consist of a borosilicate glass U-tube (diameter 25mm)
with 50cm high open tubes at both ends. Has one riffled arm for easy
connection to rubber tubing. Mounted on a wooden board fixed
to a wooden stand. A metric scale is fitted the arms of the
tube. It is recommended to use color water for greater
visibility in demonstrations.
No. SF222-MD. Only $26.95. |
