1. Introduction 

 
Thank you for buying a product from Specac. 
 
The Specac Mini-Pellet Press P/N GS03940 has been designed to 
produce a maximum 2 tons load and when used with the 7mm Pellet 
Die assembly P/N GS03950, provides a sufficient load for the 
formation of excellent quality KBr pellets with a 7mm diameter, prior to 
solid sample analysis by FTIR spectroscopy. The Mini-Pellet press and 
7mm Pellet Die assembly items are an alternative to the use of, 
typically, a 13mm diameter pellet die assembly within a 15 ton manual 
hydraulic press to produce 13mm diameter KBr pellets/discs.  
 
When the 7mm pellet die assembly with a KBr sample has been 
placed in the Mini-Pellet Press, a 2 tons load can be easily and quickly 
applied by turning of a pressure screw hand knob. This action 
compresses a hydraulic fluid (oil) to raise a pressing piston and 
compress a sample held in the pressing area. To assist in the turning 
of the pressure screw knob an M8 (6mm A/F) size short handled Allen 
key is included to fit the central socket screw for greater leverage if 
required. To help in knowledge of the load being applied there is a 
small pressure indicator gauge on the press body which shows the 
actual pressure being applied and when to stop turning the hand knob.

 

 

  
The Mini-Pellet Press is small and relatively light enough in weight that 
it could be held in the hand to turn the pressure screw knob if desired, 
but for more secure use the press has been designed to sit and work 
on a bench surface. 
 

Warning: 

If you use the Mini-Pellet Press near the edge of a bench  

  surface to turn the pressure screw knob, be careful that as  
  much of the weight of the press as possible is on the bench  
  surface itself, to prevent the press from falling to the floor.  

 
There is no requirement to permanently bolt the press to a work 
surface to apply a load safely to a sample, thus enabling easy storage 
of the press if needed.
