a needle for spinning two or more solutions simultaneously
The sealed coaxial needles are manufactured in AISI 316 stainless steel and are assembled entirely by a laser welding process to guarantee maximum geometry precision and high levels of cleanliness in order to eliminate any risk of contaminating the solutions.
Two standard versions are available with two or three concentric layers, which can be customized upon request.
