Item Name:
Fused Quartz Tubing - 9.1mm x 2.3mm
SKU:
ABRQT21
Description:
This fused quartz tubing is a clear, high-purity quartz glass tube supplied in straight lengths with a consistent round bore and outside diameter. Fused quartz is chosen in lampworking and scientific glass work when you need excellent thermal shock resistance, strong performance at high working temperatures, and a clean, stable material for components that will see repeated heating and cooling. This size is commonly selected for small-to-medium tubing work where you want a manageable outside diameter with enough internal volume for airflow, small passages, or compact assemblies.
How it is used:
- Heat the tubing evenly in a neutral flame and rotate continuously to prevent sagging and to keep the tube round.
- Pull and taper the tubing to create small stems, connectors, and transitions where a controlled inside passage is needed.
- Seal one end to form closed-end tubes, ampoule-style blanks, or small reservoirs before adding attachments.
- Join to other quartz components by bringing both pieces to an even working temperature and fusing with steady rotation to maintain alignment.
- Fire-polish cut ends after sizing to reduce sharp edges and help prevent stress concentrations.
