It is a high-quality insulated metal hose designed for precise and safe thermoregulation in laboratory environments. Featuring a nominal width of NW12 and standard M16x1 threaded connections, this flexible tubing is specifically engineered to handle the thermal demands of heating and cooling circulators. It supports a reliable working temperature range from -50 to 200°C, making it suitable for a wide variety of standard temperature control tasks involving silicone oils and other common thermal fluids. At 100cm (1 meter) in length, this hose provides a compact and efficient connection for circulators to external reactors, photometers, or viscometers. The hose is constructed from durable stainless steel and features specialized multi-layer insulation with a smooth silicone outer cover and protective end caps to minimize heat loss and ensure user safety.
