Chromatographic Columns With Frit
Product Code : EL-CC-10040
Lab Glassware Manufacturer manufactures and exports Chromatographic Columns With Frit from its Ambala, Haryana facility, supplying school, college and research laboratories in India as well as export buyers that have recently included institutions in Saudi Arabia, the UAE and Oman — part of a wider base of enquiries from across the Arabian Peninsula.
Quick answer: This chromatography column is made of Borosilicate 3.3 glass with a socket and cone joint, a PTFE stopcock, a sintered frit of porosity 0, and a GL14-threaded suction tube. The frit retains packing material while the PTFE stopcock and suction tube give controlled elution and vacuum-assisted flow during column separation.

How the Frit and Stopcock Work Together
A porosity-0 sintered frit has the coarsest standard pore size, sized to hold back typical column packing material such as silica gel while still passing liquid at a reasonable rate. The PTFE stopcock adds controlled shut-off and flow-rate adjustment, and the GL14 suction tube lets the column be connected to vacuum for faster elution when needed. This variant builds on the Chromatography Columns Plain model with these added fittings. See the full range on the Chromatography Columns page.
Frequently Asked Questions
What does porosity 0 mean for the frit?
Porosity 0 refers to the coarsest grade on the standard sintered-glass porosity scale, giving a pore size suited to retaining typical packing materials such as silica gel while allowing reasonable liquid flow.
What is the GL14 suction tube for?
The GL14-threaded suction tube allows the column to be connected to a vacuum source, which can speed up elution during column chromatography.
What material is this column made from?
It is made from Borosilicate 3.3 glass, valued in lab glassware for its resistance to thermal shock and chemical attack.
