High Pressure Autoclave from ToronTech is a pressure device with unique safety standards and TUV approval. The autoclave is a vital instrument to measure the expansion of cement when the materials are hydrated. Calcium Oxide and Magnesium Oxide both are capable of undergoing a chemical process known as hydration. This process causes water molecules to attach itself with each molecule of the oxides and thus causing the cement to increase in volume. However, this process occurs over a long period of time. An autoclave is used to estimate the effects of expansion on the cement and to accelerate the chemical reaction.
High Pressure Autoclave is specially developed for testing the volume consistency of mortar prisms. The Unit consists of a high pressure steam compartment with inner dimensions of 168mm diameter and a height of 355mm to accept a sample holder , 8 prisms as per ASTM or 6 prisms as per DIN. All parts of the pressure compartment have been chemically nickel-plated. This unit has capacity of 8 L. The pressure generated can be up to 2.5 N/mm2. A certificate is issued along with each unit’s pressure chamber to ensure that it is to standard in regards to safety.
The High Pressure Autoclave is equipped with a pressure gauge, manometer controls for pressure settings, safety pressure valve, safety temperature limiter, analogue thermometer, control lamps and ON/OFF switch. A blower on the bottom of the unit provides faster cooling. The pressurized container is insulated from the outside housing by a rock wool insulation mat.
Autoclave from ToronTech matches ASTM C151;C141;UNE 7207, and other international standards.
