EXPEC 790S

Product Instruction

Patented waveguide coupling technology for enhanced microwave excitation;
Complete microwave impedance matching to optimize microwave transmission;
Pre-pressurisation technology to ensure pressure balance inside and outside the ablation tube, with no risk of bursting;
4-10Mpa pre-pressurisation provides assurance of ultra-high pressures and temperatures.

Single reaction chamber, with all samples reacting at the same pressure/temperature for greater uniformity of digestion;
Lined and protected bottom temperature measurement without contact with the sample solution, avoiding rapid ageing of the temperature sensor.

Rapid cooling of the reaction chamber

l Programmed independent cooling water circulation for rapid cooling of high temperatures;
l Precision spiral water cooling process to enhance heat exchange area and maximize cooling time;
l Rapid cooling with no secondary boiling due to pressure relief.

High pressure chamber design made of duplex steel, with up to 30MPa load bearing capacity of the outer cover and jaws
Overpressure protection and automatic pressure relief for safety in use
Precise temperature control, real time display of pressureand temperature, status at a glance
Comprehensive system safety interlock (temperature, pressure, cooling water, exhaust air, hatch)
Compliant with GB/T 26814 Microwave Disintegration Devices and standard design codes for pressure vessels
