This product will be discontinued SALE as long as stock lasts.
Glass tube with an outer diameter of about 6 mm. Wall thickness about 1 mm. Made of soda-lime glass. Piece just over 20 cm in length. We cut the pieces ourselves, hence one tube can be just a bit longer than the other.

Intended for assembling setups yourself. The glass is fairly easy to work with: cut into small pieces and bend into curves or capillaries.
