- Page 11 Mini-Pellet Press should be fully unwound to its start position. Turn the pressure knob (4) anticlockwise until it will turn no further such that the screw assembly has reached its end stop. When the pressure screw hand knob assembly (4) is fully retracted, the pressing piston (11) will be at its correct start position for pressing.
- Page 12 User Manual Before turning the pressure screw knob assembly (4) to apply a load, tighten the lead screw handle assembly (3) a little further clockwise to continue the initial compaction of the KBr powder mixture contained within the die. When the lead screw (3) can no longer be hand tightened, the KBr powder mixture is ready to be fully compressed by application of a load provided by turning of the pressure knob screw assembly (4).
- Page 13 Mini-Pellet Press Positioning the KBr Pellet Die Ring Holder in the Spectrometer Having removed the compressed 7mm pellet die assembly (1) from the Mini-Pellet Press, the top anvil (8) and bottom anvil (9) are separated/removed from the die ring holder (6). Hold the knurled outer edge of the die ring holder (6) with one hand and twist/turn the anvils (8 and 9) by holding their knurled edges with the other hand.
