The inner container material, made of imported TFM, and the PEEK external container and imported fiberglass stand out, guaranteeing durability and resistance. Furthermore, its pressure control range goes from 0 to 15MPA and the internal container’s temperature limit is 300℃. The microwave power is adjustable up to 1000W, allowing greater adaptability in procedures.
PreeKem: Technical Specifications and Advantages
Manufacturer PreeKem, on the other hand, offers the COOLPEX model with 10 containers. The pressure or temperature test method was not specified. Its container volume is somewhat smaller, with 60ml.
The inner container material is PFA, known for its chemical resistance. The pressure control has a fixed limit of 15MPA and the internal container’s maximum temperature is also 300℃.
Advantages and Disadvantages
As for advantages, Kalstein stands out for its variety in container capacities, greater container volume, and the ability to adjust the microwave power. Meanwhile, PreeKem stands out for the quality of its materials.
As for disadvantages, Kalstein may be more costly given its high customization and superior quality. PreeKem, although more economical, offers less flexibility in its specifications.
