Tubes, Sealed With Reduced Ends, With Sintered Disc, (Pipeline Filters)

Quick answer: These sealed borosilicate tubes with a reduced end and an integrated sintered glass disc act as in-line pipeline filters, retaining particulates from gases or liquids as they pass through a closed laboratory fluid path. Tubes, Sealed With Reduced Ends, With Sintered Disc, (Pipeline Filters) is priced at approximately ₹450 (indicative market benchmark, incl. GST, August 2026).

These pipeline filter tubes combine a sealed borosilicate tube with reduced ends and a fused sintered glass disc, allowing them to be fitted in-line within a laboratory gas or liquid delivery system to trap particulates before they reach downstream apparatus. The sintered disc’s porosity determines how fine a particulate it retains, and borosilicate construction keeps the component chemically inert against most common laboratory reagents and solvents. This kind of in-line filtration is useful wherever a laboratory setup needs to protect sensitive downstream glassware or instrumentation from particulate contamination in a gas or liquid stream, including standard college and research chemistry laboratory setups.

Technical Specifications

Applications

• In-line filtration of gas or liquid streams in a laboratory fluid path
• Protecting sensitive downstream glassware or instrumentation from particulates
• College and research chemistry laboratory setups requiring inline gas/liquid purification
• General-purpose particulate retention in closed laboratory systems

Care & Maintenance

• Clean the sintered disc regularly to prevent particulate buildup from restricting flow
• Avoid mechanical shock to the sealed ends, which can crack the borosilicate body
• Use an appropriate cleaning method for the disc porosity grade to avoid clogging fine pores
