This silicone tubing has a 4mm bore and 1mm wall thickness, sold per meter. The tubing is seamless, non-toxic, and translucent, with high flexibility that makes it suitable for connecting to glass apparatus in laboratory setups. Silicone tubing provides excellent temperature resistance, chemical inertness, and flexibility retention over time compared to rubber tubing. The translucent construction allows visual monitoring of fluid flow. Suitable for general-purpose laboratory fluid transfer and gas line connections.
