Welcome Quadaxial Needles

We've been making quadaxial needles for a number of years - but always on a custom basis. Recently, with an increase in interest in both our triaxial and quadaxial needles, we decided to automate the ordering prices for quadaxial needles. In addition, we now offer a prebuilt quadaxial needle.


Prebuilt Quadaxial Needle p/n 100-10-QUAD-24181410

Think of a quadaxial needle as a needle in a needle in a needle in a needle. That's a lot of needles. Four unique liquids can be pumped through this device. Using electrospinning techniques, core-shell micro and nanofibers can be produced with functional materials embedded at different layers of the fiber. In electrospraying applications, bioactives, initiators, and other extracts can be encapsulated. Our quadaxial needles are currently being used in a wide variety of pharmaceutical, biomedical, tissue engineering, and filtration applications.

The prebuilt version features an inner most 24g needle followed by an 18g, 14g, and finally a 10g outermost needle. For a drawing of the prebuilt quadaxial needle (p/n 100-10-QUAD-24181410), see http://www.ramehart.com/pdf/quadaxial_prebuilt_24181410.pdf.

New Tubing Options
We have also recently expanded our tubing options. In addition to Tygon tubing, we now also offer a PTFE Tubing Kit with enhanced chemical resistance for use with solvents, polymers, and virtually any fluid used for electrospinning or electrospraying.

The PTFE Tubing Kit (p/n 100-10-PTFE-KIT, shown above) includes a two-foot length of premium PTFE tubing which can be cut to length, a Male Luer Coupling which connects to any Style A inlet on any prebuilt or custom coaxial, triaxial, or quadaxial needle and has a push-to-connect fitting to connect to the tubing, a Female Luer Coupling which connects to any syringe with an industry-standard Luer interface and also features a push-to-connect fitting to connect to the tubing.

The tubing and fittings are also available separately. For more details on the PTFE Tubing Kit and other popular spinneret accessories, see this page: https://www.customspinnerets.com/accessories. To purchase the tubing kit or any of the components, see http://www.ramehart.us/ptfe-tubing-kit-and-components-for-coaxial-needles/
