Nano Fiber Electrospinning Unit
The Nanofiber Electrospinning Unit, manufactured by Holmarc Opto-Mechatronics Ltd., is an advanced research instrument used for the fabrication of ultra-fine nanofibers from polymer solutions using the principle of Electrospinning. It operates by applying a high-voltage electric field to a polymer solution, leading to the formation of a charged jet known as the Taylor cone, which elongates and solidifies into nanofibers as the solvent evaporates, with the fibers subsequently collected on a grounded or rotating collector. The system consists of key components such as a high-voltage power supply (typically 0–30 kV), a syringe pump for controlled solution flow, a spinneret (needle or coaxial) for dispensing the solution, a collector system (stationary or rotating mandrel at 300–4000 rpm) for fiber deposition, a fume hood chamber for safe and controlled operation, and computer-controlled software for precise adjustment of parameters like voltage, flow rate, and spinning time. The instrument can produce fibers ranging from approximately 50 nm to several micrometers and supports a wide range of materials including polymers, proteins, carbon-based, and inorganic substances, with flexible configurations for horizontal or vertical spinning. It enables uniform fiber formation with controlled diameter and morphology and is widely applied in tissue engineering, drug delivery, filtration membranes, protective textiles, sensors, energy storage, nanocomposites, and advanced functional materials; its advantages include high precision, the ability to produce aligned, random, or core–shell fibers, user-friendly programmable operation, and suitability for both research and prototype-scale production.
