Glass Expansion Adapters – Precision Ground Borosilicate 3.3

Maximum Laboratory Versatility:

  • Function: Seamlessly connects a smaller Socket (Female) to a larger Cone (Male).
  • High-Quality Glass: Manufactured from expansion 3.3 borosilicate glass for superior thermal durability.
  • Standardized Taper: Precision-ground joints ensure compatibility with all standard lab glassware.
  • Safe Handling: Heavy-wall construction provides extra strength at joint stress points.

Expanding Your Lab's Potential

The Yash Instruments Expansion Adapter is an indispensable tool for complex laboratory setups. It provides the necessary interface to fit glassware with larger joint sizes into apparatus with smaller sockets. This is particularly useful when scaling up reactions or adapting specialized sensors and thermometers to standard flasks.

Our expansion adapters are designed with a focus on vacuum-tight integrity. The frosting of the ground joints is executed to exact tolerances, ensuring that even under high-pressure distillation or low-pressure vacuum filtration, your seals remain secure and leak-free.
