Nozzles for Electromagnetic Encapsulation Units with Sapphire

The nozzle holder is made of stainless steel 1.4435 (AINSI 316L). For the nozzle itself we use a polished sapphire. The reason for this you see in the next picture: Just look at the perfect surface of the hole and compare it with the stainless steel surface! The manufacturing of such perfect sapphire nozzles is based on the renowned Swiss watch maker tradition, which helps us to reach this perfectly smooth surface. This is essential for the generation of an absolutely perfect laminar jet as shown below.

1) restricted amount on stock
2) non stock items will be produced on order
3) typical for low viscosity alginate (2%)

Some technical details:

The hole of the sapphire is drilled with a laser. Thereafter it is polished with a special tool. The smallest polishing tool fits into the 100mm hole. Thus for manufacturing reasons the 100mm nozzle is the smallest available with the sapphire technology.
