The GTP-1 tablet press
uniquely controls force
Description
The Gamlen Tablet Press is a small purpose built
portable tablet press working under computer control
at punch speeds of 1.0-60mm/min using a V shape
compression waveform and dwell time of 100ms.

Uniquely it has two modes – working as a tablet
press (Compaction Mode) and also as a tablet
hardness tester (Fracture Mode). The press can be
operated in a glove box under precise humidity
and temperature control. It is ideal for materials
testing and tablet research, development and
small scale manufacture.
In operation the die is manually filled and the
machine operates under automatic compression
force or displacement control. Ejection is in the same
direction as compression; tablets are pushed through
the bottom of the die into a tablet holder which is
removed from the machine.
The GTP-1 accurately applies a specified force
to the measured weight of powder in the die
In contrast, other tablet
presses can only record the
value of the force applied.
This is determined by the
position of the compression
rollers, or punches, and the
amount of material in the
GTP-1 principle
die. The force applied on
a tablet press cannot be
specified by the operator
The compaction force
applied determines
important tablet properties
such as dissolution
Rotary press
hardness and friability
