Thermal regulated Block for the performance of aging tests in air and in liquids of elastomeric materials at temperatures up to 250°C. Technical Characteristics The instrument is fitted with: ? aluminium block with 4 calibrated holes designed for the insertion of 4 glass test tubes ? stainless steel housing with thermal insulation and external rack for easy sample preparation ? 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 ? safety switch to prevent overheating Accessories Glass tubes with 38 mm diameter and 300 mm length Water-cooled reflux condenser Test stations: N° 4 glass tubes with 38 mm diameter and 300 mm length The use of individual test stations eliminate cross-contamination among different products under test Heating system: The thermal resistance surrounding the round-shaped aluminium block ensures uniform heating of the system Vapour phase recovery: By condensation with water-cooled reflux condenser Temperature control range: From room temperature to 250°C (Resolution 1 °C) Timer for set of test time: Timer with set of hours and minutes with automatic swiching off of the heating system at the end of the time
