ChemBria’s thin capillary tubes are manufactured with uniform 0.3 or 0.5 mm outer diameter and available in 100 mm and 200 mm lengths. They provide consistent capillary uptake and controlled sample transfer without the variability of a manually flame‑pulled glass.

The 100 mm tubes support standard TLC routine reaction monitoring, while the 200 mm format is optimized for sampling from a NMR tube or through a needle, without compromising septa integrity for air‑sensitive setups.

There are 1000 TLC capillary tubes in a package.
