Expansion Adapters Manufacturer,Supplier and Exporter in India
Product Code : EL-CA-11577
The Expansion Adapters are borosilicate glass laboratory adapters used to connect different-sized ground glass joints in supervised chemistry glassware assemblies. They are suitable for school chemistry labs, college laboratories, organic chemistry setups, chemical analysis practicals, distributors, and institutional procurement teams.
Product Description
Expansion Adapters from School Equipments India are listed with product. The confirmed design has a large socket at the top and a smaller sized cone at the bottom. The adapter is made from borosilicate glass and fitted with ground glass joints.
This adapter helps teachers and lab technicians connect jointed glassware pieces that have different joint sizes. The confirmed socket size is 24/29, and the confirmed cone size is 19/26. It is useful in distillation, reflux, preparation, and chemical analysis assemblies where compatible ground-glass components must be joined securely.
Key Features
- Expansion adapter design: connects a larger socket arrangement to a smaller cone joint.
- Borosilicate glass construction: confirmed glass material for routine chemistry glassware use.
- Ground glass joints: supports proper fitting with compatible jointed laboratory glassware.
- 24/29 socket size: confirmed top socket size for matching larger jointed components.
- 19/26 cone size: confirmed bottom cone size for connecting smaller compatible glassware.
- Chemistry lab utility: useful for distillation, reflux, preparation, and chemical analysis setups.
- Compatibility-focused item: joint fit, apparatus alignment, and chemical suitability must be checked before use.

How to Use the Expansion Adapters
- Inspect the adapter for cracks, chips, poor grinding, or contamination before use.
- Confirm that the 24/29 socket and 19/26 cone match the connected glassware.
- Clean and dry the joints before assembling the apparatus.
- Insert the smaller cone into the compatible socket without forcing the joint.
- Connect the larger socket to the matching cone of the second glassware item.
- Support the full assembly with clamps, stands, or joint clips where required.
- Check that the apparatus is aligned before heating or adding reagents.
- Allow the assembly to cool before separating and cleaning the adapter.
Safety note: Use only under teacher or laboratory-supervisor control. Do not force mismatched joints, use cracked glassware, heat unsupported assemblies, block vents, or use the adapter in vacuum or pressure systems unless the complete apparatus is confirmed suitable.
Care & Maintenance
- Clean the adapter after use with an approved laboratory glassware cleaning method.
- Dry fully before storage to reduce residue and joint sticking.
- Store in a padded or separated glassware cabinet to protect ground joints.
- Reject the adapter if the socket, cone, or glass body is cracked, chipped, or jammed.
