GL45 Safety Cap for Food, Bottle Lid

【GL45 Compatibility】This laboratory safety feed cap is specifically designed for GL45 standard threaded glass containers, providing a stable port configuration for liquid feeding and mobile phase sampling. Its 2-port design allows for simultaneous handling of two tubing lines without compromising bottle balance or fluid flow.
【Stainless Steel Core】Featuring a durable PBT outer cap and a 304 stainless steel inner cap, this laboratory safety feed cap ensures structural rigidity and reliable rust resistance. The metal core resists mechanical deformation during routine tightening, providing robust support for fluid transfer and sampling operations.
【Heat and Pressure Resistance】Designed to withstand temperatures up to 140°C and internal pressure fluctuations, this laboratory safety feed cap maintains its shape integrity and dimensional stability. This thermal resistance reduces the risk of structural failure or cracking during demanding heat and fluid transfer processes. [Leak-proof seal] Equipped with a precision inner cap and dedicated sealing washer, this laboratory liquid transfer cap forms a firm, leak-proof seal against the bottle neck. This reliable closure helps prevent chemical spills, reduces liquid evaporation, and maintains a clean and safe experimental environment. [4-6 mm interfaces] Configured to support small-diameter tubing interfaces between 4 mm and 6 mm (0.157 to 0.24 inches), this laboratory safety feed cap allows for controlled fluid feeding and removal. Each package includes a feed cap, inner cap, and washer, facilitating routine maintenance and immediate implementation in the lab.
