Non-Restrictive Microperfusion Probe

The Lenox Laser Corporation has released the Non-Restrictive Microperfusion Probe for nano/micro-liter fluid sampling and delivery. The NRMP is a closed-end thin wall #304 stainless steal needle with a cylindrical array of laser drilled apertures having effective diameters of 10 microns. The NRMP is available in 27, 38, 30 and 33 gauge needles - each having a total aperture area equal to the cross-section area of the tubing. This provides the user with the ability to extract or deliver fluid without generating a large pressure gradient at the point of application. Probes are available in lengths of 25mm to 75mm. Custom perforation arrays (up to 1000 holes) having aperture diameters from 5 to 20 microns are also available (Luer tubing connectors are optional).
