Thistle Tubes, Flint Glass

Add liquids safely to flask setups while keeping apparatus assembled.

• Flared top supports controlled pouring and careful filling
• Long stem reaches into assembled apparatus
• Useful for reaction-vessel demonstrations

Helpful when a liquid must be added into a flask or generator while the rest of the apparatus remains connected.

Use the shorter stem thistle tubes where compact glassware setups are needed. The compact choice allows for reaction setups where a full-length thistle tube is unnecessary or difficult to position.
