Precision Bore Tubing

Veridia Precision bore tubing

ShrinkingVeridia is our trade name for precision bore glass tubing which is used widely in laboratories and industry for precision dispensing and measuring. Veridia replaces many other materials where precision bore is required, with the ability to provide a product that is highly stable in both temperature and chemical applications as well as providing a highly visible product. We manufacture glass tubing to suit your specific application. Bore sizes ranging from 0.1mm to 75mm are available from our large range.
If you require a particular size to fit an existing piece of equipment we can produce this for you to the most exacting standards with a tolerance as low as +/- 3 microns.

* = Please note in the final range of precision bore sizes, the full scope of wall thickness dimensions are only available on certain bore sizes.

The table above lists the standard wall thickness sizes available for the precision bores diameters we can produce, with a wide range of tooling available we can manufacture many sizes with the ranges listed. For sizes to meet your exact needs we can supply tooling at a competitive price or work with your tooling, subject to compatibility.

Flow meters

We manufacture (variable area) flow meter tubes (mouldings) to O.E.M. specifications. Many companies worldwide rely on Chance to produce their vacuum formed flow meter tubes. These can be supplied unfinished i.e. ends ground square and or flame polished. If you wish, we can supply the mouldings 'as cut' for your engineers to finish to suit your final application.
