Built for Gravity Chromatography
The round bottom and reinforced beaded top suit routine gravity-fed chromatography work, while the coarse-porosity fritted disc supports the packing material without a separate retaining plug. The PTFE stopcock gives controlled shut-off and flow adjustment at the base of the column. See the full range on the Chromatography Columns page.
Frequently Asked Questions
What does the beaded top do?
The reinforced beaded rim at the top strengthens the opening of the column against chipping and gives a clamp or closure a secure place to seat.
What is the fritted disc for?
The coarse-porosity fritted disc supports the column packing material in place while allowing the mobile-phase liquid to pass through during gravity chromatography.
Why is heavy-wall construction used?
Lab Glassware Manufacturer designates its columns as heavy-wall construction to increase safety and durability during routine laboratory handling.
