Flexible hoses made natural rubber or PVC are enjoying great popularity in laboratories. VACUUBRAND offers special hoses made of antistatic PTFE with small flanges of 1.4305 stainless steel. The PTFE tubing is virtually smooth-walled on the inside with high conductance and minimal surface area, which keeps condensate from accumulating such as in corrugated hoses. The antistatic PTFE has excellent resistance to chemicals and antistatic properties (< 107 Ohm resistance between the inside and flanges) to prevent electrostatic charging. Stainless steel bellows and corrugated hoses with TIG-welded small flanges meet high requirements in terms of outgassing and cleanliness. These metallic hoses are made of 1.4541 stainless steel, and are vacuum annealed.
