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.

There are 3 methods by which a solid material is brought to the form acceptable to the instrument.

1. KBr Disc Technique
2. Mull Technique
3. 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 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,
Power         : 230 V, 50 Hz, 100 W

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.
