SIC20 Suction Cup

Product name：SIC20 Suction Cup

Item：SIC20

Details：

The SIC uses a specially designed Silicon Carbide (SiC) cup instead of a ceramic one. SiC is sintered at 2500 °C and is chemically much more passive than ceramic or borosilicate. The bubble point is 90 kPa.

Applications

· Continuous/discontinuous extraction

Benefits

· High permeability

· Low sorption

· Very low dead volume

· Shaft and cup exchangeable
