Greaseless Stopcock

Features

  • The glass tube is made of borosilicate glass and there are two types of pistons which are made of glass or PTFE. The both pistons maintain high vacuum state 10-6torr. As some of PTFE O-rings and FKM O-rings are used in the part of a piston, these O-rings are effective in high chemical resistance and high vacuum state etc. These O-rings are even interchangeable and we can offer another kind of O-ring such as Perfluoro.
  • Please check the page of "about O-ring of Glassware" and contact us.
