Spinnerets & needles
Feed two spinning solutions through separate channels and rotate the twin nozzles to form twisted composite fibers. Designed for electrospinning writing, with mounting compatibility for TL-Trinity.
The dual-channel extrusion mechanism delivers two spinning solutions at the same time. Continuous nozzle rotation twists the emerging fibers before collection. A bearing assembly separates rotation from fluid delivery, keeping the supply tubing stationary as the nozzles rotate.

Enlarge image ↗Liquid A and liquid B travel through separate flow paths to the twin nozzles. The motor drives the lower rotating assembly through a coupling and bearings. Keeping the feed conduits stationary prevents tubing from winding around the rotating head.

Explore TL-TrinityStandard Luer-lock connections allow quick changes between 18G–32G needles.
A centrally mounted adjustment disk allows coplanar and coaxial positioning of the twin nozzles.
The linear slider adjusts the collection distance over a 50–300 mm range.
The groove-aligned flange supports quick disassembly and reassembly for maintenance.
