VWR Screw Cap 38-439 External Thread HDPE Autoclavable 1000 Caps

The VWR 16465-86753 Screw Cap is a laboratory closure designed for securely sealing bottles and containers. This cap features a 38-439 external thread, a specific size that ensures compatibility with various laboratory bottles that have a matching thread finish.

Constructed from HDPE (High-Density Polyethylene), this screw cap is a durable and chemically resistant plastic material. HDPE offers good chemical inertness, making the cap suitable for use with a wide range of laboratory reagents and solvents. A key feature of this cap is that it is autoclavable, meaning it can withstand the high temperatures and pressures of an autoclave. This allows for sterilization of the cap for use in aseptic applications, or for sterilizing the contents of a bottle with the cap loosely fitted. The screw-on design provides a secure and leak-proof seal when tightened, preventing evaporation and contamination.

This VWR screw cap is a versatile and essential accessory for various laboratory storage and handling needs.
