Overview
Pneumatic cutter for the preparation of constant-volume samples for MD Rheometer, OD Rheometer and Mooney Viscometer from polymer or green rubber compounds.
The solid construction of the machine and the double-piston system permit to obtain constant volume samples even with hard and high viscosity compounds.
By using samples with constant volume for your rheology tests you will increase test repeatability ensuring correct filling of test chamber.

Key Features
• Exclusive adjustment system, which permits to set the machine to obtain samples for:
- Moving Die Rheometer
- Oscillating Disk Rheometer
- Mooney Viscometer
• Puncher for obtaining the central hole in the lower sample for the Mooney viscosity test
• Pneumatically-activated safety panel
• CE Labelling

Select the Type of Sample
The selector, located on the back of the instrument, allows you to select the type of specimen to be produced.

Puncher for Hole for Mooney Sample
A puncher, incorporated in the instrument, permits the central hole to be made in the lower sample for the Mooney viscosity test.
The pneumatically-activated safety panel ensures the conformity of the instrument with CE safety requirements.

Safety devices
The instrument is equipped with:
• Pneumatic activation of the safety protection screen
• Safety switch, which prevents the activation of the piston if the Safety Protection Screen is not closed.
• CE Labelling

Development and production
The instrument is totally developed and produced in the plant of Gibitre Instruments in Italy.
All the mechanical parts are produced in the company workshop using modern CNC machines.
Components and sensors from well-known brands are selected in order to ensure the maximum reliability in the measures
Internal trained personnel takes care of all the production stages: assembly, start-up, calibration, packing, shipment and installation.
