The Gibitre Thermoregulated Block accelerates aging of elastomeric materials in air or liquids up to 250 °C, enabling laboratory measurement to ISO 188, ISO 1817, ASTM D865 and ASTM D471.
Four independent stations allow parallel testing of different materials, reducing cycle time and enabling direct comparison.
Temperature is regulated by a PT100 probe with PID control, integrated timer and automatic heater shutoff for stable, repeatable aging.
A thermally insulated stainless-steel housing and an aluminum block with calibrated wells for glass tubes, plus an over-temperature safety switch, ensure safety and long-term reliability.
An external rack simplifies sample preparation and handling; accessories include 38 mm × 300 mm glass test tubes and water-cooled reflux condensers for liquid aging.
CE-marked, the Gibitre Thermoregulated Block is a robust addition to laboratory testing tools for elastomer measurement, delivering consistent, standards-compliant results.
Thermal regulated Block for the performance of aging tests in air and in liquids of elastomeric materials at temperatures up to 250°C conforming to ISO 188, 1817 ASTM D 471 and 865 Standards.
Aging tests are typically carried out to measure the variation of characteristics of an article before and after the aging process. The characteristics that are most frequently measured before and after aging are:
• Variation of mechanical characteristics (loading, lengthening, tearing)
• Variation of hardness
• Percentage variation of mass and volume.
Gibitre, in addition to providing this tool to perform accelerated aging in air or in liquid, also provides the tools to measure changes in the properties of the article and to produce the related reports.
The instrument is fitted with:
• Aluminium block contained in a stainless steel housing with thermal insulation with 4 calibrated holes designed for the insertion of 4 glass test tubes
• Heating resistance
• PT 100 thermal probe for temperature measurement
• PID thermoregulator
• Timer for the set of the heating time with automatic switch off of the heater at the end of the set time
The instrument is equipped with a timer that can be set between 0 and 99 hours and 59 minutes. The instrument automatically stops at the end of the set test time.
The Timer allows you to activate aging cycles by ending the test automatically in the absence of the operator.
4 glass tubes with a diameter of 38 mm and a length of 300 mm can be inserted into the instrument.
The specimens can be inserted into the glass tubes and locked using the fasteners provided.
Fixing devices allow the specimens to be placed in order to avoid contact with the glass tube walls.
The glass tubes are closed in the upper part with PTFE plugs provided with holes for the insertion of the glass pipes requested for the aging test in hot air according to ASTM D865
For aging tests in volatile liquids it is necessary to use condensation columns connected to a water supply. The condensation columns allow to condense the volatile part of the test liquid and make it fall back into the tube. In this way, the amount and formulation of the liquid in the glasses will remain unchanged.
A condensation column can be applied to each test tube.
Together with the instrument are supplied two side supports for housing the glass tubes not in use. The supports can be removed to reduce the overall dimensions of the instrument.
• Safety switch to prevent overheating
• Safety Push-button
• CE Labelling
The calibration is performed with reference to the requirements of ISO 1817 standard.
The service includes:
• Ordinary maintenance of the instrument
• Calibration of the temperature inside the testing tubes (at 70°C, 150°C, 200°C, 250°C).
• Issue and e-mail shipment of the Calibration Certificate with traceability to primary standards.
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.
