The glass components are manufactured from WHEATON® low extractable borosilicate glass 3.3. that conforms to ASTM E 438 Type I, Class A requirements. The 25 mm filtering apparatus are designed to handle small volumes of liquids, the 47 mm filtering apparatus are suitable for volumes up to 1000 ml. The 90 mm filtering apparatus are recommended for large sample volumes, liquids with a heavy particulate load and viscous liquids when a high flow rate is required.

Furthermore, the following versions are offered:

Filtration assemblies with stopper connections:

  • Designed for analysis of particulate or microbiological contamination
  • For flasks with a No.2 hose connection for 1/4" (6mm) I.D. tubing

Filtration assembly with standard taper 40/35 joint connection:
  • Recommended for routine filtration of organic solvents, corrosive liquids and the removal of particulates from HPLC solvents
  • Ground glass connection eliminates phthalate contamination that can occur from silicone or neoprene stoppers
  • Drip tip on the support bases extends below the hose connection preventing filtrate from entering the vacuum line
  • For flasks with a No.2 hose connection for 1/4" (6mm) I.D. tubing

Filtration assembly with GL45 thread connection:
  • Designed to collect the filtrate directly into a standard laboratory bottle
  • Connection to the bottle is made with a polybutylene terephthalate (PBT) cap and a PTFE-faced silicone sealing ring

Recommended for general filtration.
