Laboratory Miniature Twin-Screw Extruder WLG05/WLG05G
I. Purpose. The miniature twin-screw extruder is a highly efficient plasticizing, mixing, and extruding device mainly used for processing polymer materials. It can accomplish filling modification, blending modification, powder granulation, and degassing/devolatilization of various polymer materials. Materials can be directly extruded into shape, or the melt can be sent to the next process (injection molding). II. Technical Parameters. 1. Material amount per single run is about 10 g, with temperature accuracy of ±2 °C. 2. Materials can be directly extruded, or circulated multiple times inside the chamber before extrusion. Polymerization and melting time can be controlled. 3. The chamber cover can be opened to observe...

Electrospinning Machine
The Sibeining SNZJ-1400 series electrospinning machine is a cost-effective electrospinning machine developed by Qingdao Sibeining Intelligent Equipment Co., Ltd. specifically for universities, research institutes, and other R&D institutions. It features a carefully selected intelligent high-voltage power supply with automatic overvoltage and overcurrent power-off protection for operator safety. The machine is equipped with a four-channel color touch-screen syringe pump that is easy to operate and fully functional, enabling efficient single-material spinning as well as multi-material mixed spinning. In addition, it is equipped with various collection devices to meet diverse experimental needs such as aligned fibers, random fibers, and tubular fiber membranes. The equipment is simple to assemble and flexible to place on laboratory benches, fume hoods, glove boxes, desks, and other locations. It is easy to store and highly modifiable: syringe pumps can be added for coaxial spinning, and constant-temperature/humidity chambers can be added to improve environmental temperature and humidity stability.
