KBr PRESS MODEL MP-15
The press is capable of producing
pressure upto 15 tons. It is compact in construction &
occupies very little bench space. Acrylic screens are
provided for the safety of the operator. The base plate
has a provision for bench mounting. A pressure gauge for
indication of pressure release valve is provided. A
telescopic handle is used for extra leverage.
KBr Press Model MP-15,fixing bolts for table mounting.
Rubber antislide sheet, Oil Bottles -2 Nos., Safety
sheets-2 Nos.
There are 3 methods by which a solid
material is brought to the form acceptable to the
instrument
-
KBr Disc Technique
-
Mull Technique
-
Liquid sampling

KBr Disc Technique
In this technique a few milligrams of sample are ground
with about 250 mg of finely divided spectroscopic grade
KBr powder & the mixture is placed in a die. By the
application of pressure to the powder mixture, a thin
disc (Pellet) is made for examination. Since the KBr has
no absorption in the fundamental region of IR Spectrum,
only the spectrum of sample is obtained.
A compact laboratory hydraulic press capable of
producing a force about 10-15 tons is required.

KBr PRESS (AUTOMATIC) MODEL AP-15
This is electrically operated version
of the manual press. The pumping is done by gear
motor drive. Simply press a button & it will start
building pressure & will stop autom-
atically at set pressure by means of a pressure switch.

NOTE :
Higher capacity press with larger plate size are
available for specific applications. Ask for
specifications giving details of your requirement

KBr DIE
The evacuable 13 mm KBr die is
manufactured from hardened stainless steel. The steel
pellets that come into contact with the sample mixture
have optically polished faces. A finely ground mixture
of sample & IR grade KBr is pressed into a disc using
the die. The die is fitted with a tube by means of which
it can be evacuated.
Evacuated 13 mm KBr die, including two
optically polished pellets & extractor ring for sample
disc removal. Most commonly used die is of 13 mm
pellet size. It should have highly polished surfaces &
should withstand atleast 10 tons pressure. Dies for
other pellet sizes are available for specific
applications.

Dry Box
The dry box is specifically designed
for the storage of accessories & windows which are
affected by moisture. Transparent lid gives a clear view
of the contents.
Usable Volume: 450 X 250 X 150 mm.
Temperature : 10° to 15° C above ambient,

Vibration Mill
Vibration Mill suitable for mixing of
sample & KBr, using S S Ball. The mixing & blending of
KBr with sample can be easily done using the Vibration
Mill. The sample is contained in stainless Steel capsule
and reduced to fine mixture of sample and KBr by the
pulverising action of grinding balls. It is fitted with
a 30 min adjustable timer for Auto Stop.
Dimensions : 215 mm x 285 mm x 180mm
Power : 230 v 50 Hz
Timer : Digital upto 30 minutes adjustable in steps of
minute. Request Quote
This vibration mill is particularly suitable for DST
user where in the sample quantity is too small and
sample homogeneity therefore is very crucial. For this
application KBr is taken in good quantity ( say 1 gm)
and sample also proportionally on the higher side ( say
10 to 20 mg) . This mixture when used in the Vibration
mill gets homogeneously mixed. A small portion of this
is taken for analysis with DST. |
