Working Principle

The straight bore stopcock operates using a precision-ground rotating plug inside the glass body. Rotating the plug aligns or blocks the internal passage, allowing precise control of liquid or gas flow. Hose connections provide secure tubing attachment, ensuring efficient transfer with minimal leakage during laboratory operations.

How to Use

1. Connect laboratory tubing securely to both hose connections.
2. Ensure the stopcock plug is properly lubricated if required.
3. Rotate the handle to regulate or completely stop the flow.
4. Avoid excessive force while operating the stopcock.
5. After use, disconnect tubing and clean thoroughly.
6. Store in a clean and dry environment.
