Two-Position Parallel Nozzle Holder, 18G-22G (CAT#: STEM-AL-5569-ZJF)

The two-position parallel nozzle holder is a laboratory dual-needle support head designed for holding two electrospinning needles in parallel. It allows two jets to operate simultaneously for higher throughput or mixed-fiber experiments. The needle spacing is selected to reduce interference between the two electric-field regions. The holder accepts several stainless-steel needle gauges. Set screws secure the needles and reduce loosening during operation. An O-terminal screw connection provides a stable high-voltage attachment point. Three fixing holes support installation on a suitable insulating stand. The conductive holder provides a shared electrical path for the two needle positions.
