Flow Through High Pressure Reactor
Designed to study reactions between gases and solid/powder samples under high pressure (between reactor’s cups), in the reactor chamber under UHV conditions. Samples could be subject to static or flowing gas, with the heating up to 750°C and the possibility of cooling down to -100°C (option).
Manufacturer
Prevac
Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.

Key Features
- Heating up to 750°C and the possibility of cooling down to -100°C (option)
- Sample mounting table can be made of stainless steel, titanium, with gold coated surfaces or other materials/alloys, depending upon application
- Special design allows for closing the whole PTS sample holder inside reactor cups, therefore there is only one sealing surface

Description
Inside the vacuum chamber of the High Pressure Reactor is a system of cups which is a closed space in which a sample have contact with gases. Opening and closing the cups is done manually by turning a reaction volume screw. The sample mounting table can be made of stainless steel, titanium, with gold coated surfaces or other materials/alloys, depending upon application. The temperature of sample holders is regulated by HEAT3-PS Power Supply.
Experiments with reactive gases at static or flow mode (temperature of gases up to 300°C) can be performed at pressure from 1 bar up to 20 bar (depends on the type of gas dosing system).
Special design allows for closing the whole PTS sample holder inside reactor cups, therefore there is only one sealing surface. This solution requires larger volume of gas.

Options
- Coldfinger for sample holder cooling
- Laser heating for fast sample heating up to 900°C
- Back pressure regulator – needed in case of experiments from 2 – 20 bar in flow mode. A dedicated gas manifold with proper flowmeters required heated outlet for the gases
- Temperature control software (HEAT3-PS dedicated software) – full software control of temperature, ramp rate and output power
- Reactor ready to work with CO and H2S (on request)
- An additional measuring equipment – for example, UMS to conduct spectrography and chromatography of the gas which is flowing out from the reactor
