The Custom Coaxial Needle with Tubing includes one or two (depending on inlet style) fittings for our 1.5mm ID PTFE Tubing which can be cut to length with a razor. Two feet of tubing is included with needle. Additional tubing and fittings are also available to complete your spinneret setup and connection to a syringe. 

Shafting is precision Type 304 Stainless Steel while the Luer connector is nickel and chrome-plated brass. These needles are autoclavable; they can be cleaned, washed, boiled, sterilized, and reused many times. Many options and tubing sizes are available to fit any application. 

Each custom needle is made to your specifications. To design and order your own coaxial/triaxial needle design follow these three simple steps:

1. Check the needle gauges with our calculator below or download the needle chart (http://www.ramehart.com/pdf/needles.pdf) to help you determine which gauge needles you require. This chart shows the ID (inside) and OD (outside diameters) for all standard needle gauges. Be sure that the OD of the inside needle you choose is smaller than the ID of the outside needle. Note that currently we are not fabricating any coaxial or triaxial needles with an inside needle greater that 28 gauge.

2. Download our coaxial needle with tubing design worksheet here: http://www.ramehart.com/pdf/coaxial_with_tubing_worksheet.pdf Figure out your inside and outside gauges along with connector type (Style T, L, or TL) for inlets. Figure out the other dimensions and options per your requirements as detailed on the worksheet. Please note that innermost needle must be 28g or lower.

3. Add this item (configured per your worksheet) to your cart and checkout. 

Note that standard delivery time for this item, since it is custom made, is one week.
