Made-to-Order Laboratory Equipment
(1) Hydraulic Pinching Tool
(2) Break-point Tester
(3) Slit Flow Tester & Angle of Repose Apparatus
(1) Hydraulic Pinching Tool
Hydraulic tube pinching tool is used to separate linac
tube from vacuum pumping system. Its function is to
pinch copper tube of ¾ inch dia. & wall thickness of 2.5
mm. Hydraulic Pinching Tool comprises of hand pump, 3
meter long flexible hose pipe, pressure gauge &
hydraulic cylinder with pinching jaws. Capacity of Hand
Pump is 10,000 PSI. Pressure Gauge is provided to know
at what pressure pinching is taking place. Jaws have
proper rounding such that pinching results in vacuum
tight joint after pinch off. Pinching takes place at the
pressure of 8,000 PSI.
(2) Break - Point Tester
Break-point tester is used for checking the
breaking-point pressure of ceramic components as well as
those made from similar brittle materials. The Item
which is to be tested for break-strength is placed in
the cavity of die plate & hydraulic pressure is applied.
The specially designed pressure indicator has 2
pointers, one of which shows the exact pressure applied
on the ceramic balls at the time of breaking.
(3) Slit Flow Tester & Angle of Repose Apparatus
Slit Flow Tester is used for studying the flow
properties of free flowing powders such as pure
terephthalic acid (PTA) powder. The sample is introduced
into a hopper with a motorized door. This door rises
allowing the powder to flow through it. The width of the
slit when 100 gms. of powder has flowed through, is
measured using a load cell. The experiment is repeated
20 times & average width is calculated. This average
width determines the flow property of the sample
powder.
Study of flow properties of free flowing powders such as
PTA is also carried out by means of Angle of Repose
Apparatus. This apparatus is used for the purpose of
determining the angle of repose of sample powder. A
sample is poured through the apparatus in a controlled
manner onto a vertical plate. The vertical height &
horizontal distance of the resultant semi-cone of powder
are used to calculate the angle of repose. This method
is capable of measuring angles of repose from 31 degrees
to 43 degrees. The latter corresponds to the worst
flowing powder which will flow freely through the
apparatus.
