Island-in-the-sea Spinneret

For many years ramé-hart instrument co. has been the world leader in custom spinnerets used for electrospinning, electrospraying, and other other applications. Based on valuable feedback from our customers, we have added an Island-in-the-sea Spinneret design to our repertoire of spinneret products. The Island-in-the-sea is much like a coaxial spinneret except that instead of having a single inner needle, it features two separate inner needles (as shown below) - each one capable of ejecting a separate liquid.

Side-by-side Spinneret
The Island-in-the-sea Spinneret is used to produce a composite nanofiber core made up of two different materials which is then enshrouded by an exterior of a third material. In some applications, a composite nanofiber is desired but no exterior is required. In this case, a Side-by-side Spinneret is what is called for. Currently, we offer a Prebuilt Side-by-side Spinneret which features two (2) 22g needles. We can also build a Custom Side-by-side Spinneret to meet your requirements. Please contact us with details of your Side-by-side Spinneret requirements and we can build to your specifications.
