Piping Procedure

Piping Materials:

Use the materials shown below for the process piping adjacent to the flow-through type holder.

•  Hard polyvinylchloride pipe 

 

 

 

Nominal diameter 25 mm

•  Polypropylene pipe 

 

 

 

 

Nominal diameter 25 mm

•  Wire rainforced soft polyvinylchloride pipe   

Nominal diameter 25 mm

•  Stainless steel pipe (JIS G3459)
    SUS304 or SUS316 

 

 

 

Nominal diameter 25 mm

Piping Example:

1.  The outlet tube should be as short as possible to expel

  the solution to atmosphere.

2.  When a horizontal outlet tubing is long, 

     a vertical tube (H) should also be long.
