Item Name:
55/50 Male Ground Glass Joint
SKU:
IND-5550M
Description:
The 55/50 Male Ground Glass Joint is a precision-formed borosilicate glass male taper joint used to create a secure, standardized connection between two pieces of scientific glassware or lampworked apparatus. This joint is constructed with a ground taper surface that is intentionally matte and finely textured so it seats tightly into a matching 55/50 female ground joint, helping form a stable fit that resists slipping during use. In scientific and functional lampworking, ground joints are used when you need repeatable alignment, easy assembly and disassembly, and a dependable seal for setups such as condensers, adapters, manifolds, traps, and custom assemblies. The 55/50 size is typically chosen for larger-diameter assemblies where strength, stability, and flow capacity matter, especially in heavier glass systems where smaller joints would be a weak point.
How it is used:
- Pair the male joint with a matching 55/50 female ground glass joint to assemble your apparatus
- Insert the male taper straight into the female taper and gently twist to seat the ground surfaces together
- Use a joint clip or appropriate support when building larger assemblies to reduce stress on the connection
- Apply a suitable joint grease only when your process requires it and when it is compatible with your application
- Disassemble by supporting both pieces and twisting gently rather than pulling straight apart
