                Features                 

What is full jacket coverage? Why is it important?

      Partial Jacket Coverage     

The structure of filter bottom is the same as its top. No jacket covers the bottom area which causes filtrate incline to get crystalized. Poor insulated filtration.

        Full Jacket Coverage      

Jacket covers down to the filter bottom. Excellent insulated filtration, especially for the material vulnerable to crystallization.

Why high vacuum can keep for YEARS without maintainence? 

- Because of Mechanical Sealing and PTFE Lid.

    Traditional Seal - Seal on Axis     

O-ring or Grease Seal is known as seal on axis to be used between stirring shaft and vessel lid, but is heavily prone to be worn out by friction, especially under corrosion of solvent and high temperature, which requires regular operation stop, disassemble and O-ring change.

  Mechanical Seal -  Seal on Surface  

Mechanical Seal is the seal on surface between its rotating part and stationary part. It is made of SiC and reinforced PTFE, which is vacuum tight, durable, long lasting and great for 24/7 operation. With PTFE vessel lid, stirring can be very stable so that mechanical seal can ensure <2mbar vacuum level.
