Needles for nanopipetting

In the automated life sciences industry, very small quantities of liquids in the micro- and nanolitre range have to be dispensed contact-free. For this purpose, Nanosol has developed a special stainless steel needle with an integrated sapphire nozzle. With this needle, volumes of up to a few nanoliters can be dispensed.

To improve the surface properties, the inner and outer surfaces of the steel tube and the sapphire can be coated with a hydrophobic sol-gel coating. The main advantages are the reduction of carry-over, the lower adhesion of blood, serum, bacteria etc., easier cleaning, the formation of a diffusion barrier and a considerably longer service life. For more information, see Sol-Gel Coating.
