Borosilicate Glass 3.3 Expansion and Reduction Adapters

LBG borosilicate glass 3.3 adapters for connecting glassware with different ground glass joint sizes. Expansion —small cone to large— or reduction —large cone to small— depending on the combination required in the assembly.

Applications

Where distillation, reflux or synthesis rigs include components with mismatched ground glass cones, these adapters resolve the incompatibility without replacing other glassware. Commonly used in organic chemistry, pharmaceutical and quality control laboratories running mixed-series or multi-manufacturer setups.

Material

• Glass: Borosilicate LBG 3.3
• Chemical resistance: Suitable for organic solvents, acids and bases at standard laboratory concentrations
• Thermal resistance: Inherent borosilicate 3.3 properties — withstands temperature fluctuations without risk of thermal shock failure
• Autoclave: Compatible with standard cycles at 121 °C

Compatibility

Designed for standard ground glass joints. Compatible with flasks, condensers, fractionating columns, addition funnels and any glassware with standard NS cones. Check the specific reference to confirm inlet and outlet cone sizes.

Technical Data

• Material: Borosilicate glass LBG 3.3
