This Burette Stopcock with Straight Bore and PTFE Key is designed to provide accurate manual control of liquid flow in burettes and laboratory glassware.
It enables smooth starting, stopping, and regulation of dispensing rates, supporting consistent dropwise delivery during titrations, analytical procedures, and routine liquid handling applications.
Suitable for primary and secondary school laboratories, universities, research facilities, and analytical laboratories, this stopcock is designed for precise liquid regulation in burettes and laboratory assemblies. It supports titration procedures, controlled liquid transfer, and other applications requiring accurate flow management.
The straight-bore design promotes smooth, unrestricted liquid flow, allowing precise adjustment of flow rates during dispensing. This responsive control helps improve repeatability and accuracy across educational, analytical, and research-based laboratory tasks.
The precision-fitted PTFE key provides reliable operation with a secure, leak-resistant seal. This helps minimise unintended flow and reduces the risk of drips during use, improving confidence and consistency throughout laboratory procedures.
Manufactured from Borosilicate 3.3 glass, this stopcock offers excellent resistance to chemical exposure and thermal stress. The durable glass material supports long-term use in demanding laboratory environments while maintaining performance and reliability.
The PTFE key delivers outstanding chemical resistance and smooth rotational movement, making the stopcock suitable for use with a broad range of laboratory reagents and solutions while helping to reduce contamination risks.
