adapter cone 14/23, free tube length 100mm

Adapter Cone 14/23 with 100mm Free Tube Length

This adapter cone is a fundamental connecting component for laboratory glassware assemblies. It features a standard taper 14/23 cone joint paired with a free tube length of 100mm, allowing it to bridge ground-glass joints and tubing within distillation trains, reaction setups, and general bench configurations. Manufactured from borosilicate glass, the adapter offers the chemical resistance and dimensional stability expected of professional laboratory equipment.

Construction and Specifications

The adapter is built around a 14/23 standard taper cone joint, which mates with corresponding 14/23 sockets to form a reliable, leak-resistant connection. The 100mm free tube section provides extended reach and a clear tube run for routing vapors, liquids, or connecting to flexible tubing. Borosilicate glass construction supports a maximum temperature resistance of 500°C, making the component suitable for elevated-temperature applications where standard soda-lime glass would be inadequate.

Typical Applications

Adapter cones of this type are used wherever a 14/23 ground-glass joint needs to be connected to tubing or extended within an apparatus. They are common in distillation, fraction collection, gas delivery, and vacuum-related setups. Because the cone conforms to the 14/23 standard, it integrates directly with a wide range of compatible glassware. For vacuum-based assemblies, this adapter complements components such as the 14/23 vacuum adapter, which shares the same joint sizing for straightforward connection.

In distillation work, the cone can be combined with matching glassware to build a complete train; pairing it with a dedicated distillation adapter allows vapor paths and receiving flasks to be linked through consistent 14/23 joints. The borosilicate glass and 500°C temperature rating make the component appropriate for setups that involve heated processes driven by heating mantles, stirrer plates and similar laboratory heat sources.

Handling and Compatibility

As with all ground-glass joints, mating surfaces should be clean and may be lightly greased depending on the application to ensure a secure seal and to ease separation after use. The 14mm inner diameter and 23mm outer diameter correspond to the standard 14/23 taper, so the adapter fits any glassware engineered to this specification. At a weight of 50g, the component is light enough to add to an assembly without imposing significant load on the supporting clamps or joints.

This product is available soon. It is well suited to laboratories standardizing on 14/23 glassware and seeking a durable, temperature-resistant adapter for routine connecting tasks.
