Types of Filtration Assembly
GLASS FILTER HOLDER - 47MM
Ÿ Made of borosilicate glass with fritted glass filter base Ÿ The base design has an integral vacuum connection located above the filtrate drip to prevent contamination of the vacuum line from droplets Ÿ Anodised aluminium spring clamp Ÿ The filter size is 47 mm 2 Ÿ The effective filtration area is 9.6 cm Ÿ Used for filtration of HPLC solvents and aqueous mobile phase solutions and buffers Ÿ The scaled funnels simplify dosing and analysis
GLASS FILTER HOLDER Silicon Stopper
Ÿ Made of borosilicate glass with fritted glass filter base Ÿ The base design has an integral vacuum connection located above the filtrate drip to prevent contamination of the vacuum line from droplets Ÿ The filtration base has a silicon stopper Ÿ Anodised aluminium spring clamp Ÿ The filter size is 47mm 2 Ÿ The effective filtration area is 9.6 cm Ÿ Facilitates analysis of particulate or biological contamination of vacuum filtering liquid

Filtering Flask with Tubulation
The short tube and hose barb effectively act as an adapter over which the end of a thick-walled flexible hose (tubing) can be fitted to form a connection to the flask. The other end of the hose can be connected to source of vacuum such as an aspirator, vacuum pump, or house vacuum. Preferably this is done through a trap (see below), which is designed to prevent the sucking back of water from the aspirator into the Büchner flask. The purpose of applying a vacuum is to speed the filtration by providing a pressure differential across the filter medium that is greater than that produced by gravity alone.
