This highly accurate miniature flow restrictor is intended for gases. It is pre-installed in a male to female Luer fitting and includes a 40 micron safety screen filter to protect the orifice from contamination. Ideal for medical applications, both the orifice and screen are constructed of 300 Series stainless steel, while the fitting is composed of medical grade polypropylene. The orifices are all 100% flow tested on nitrogen to ensure each part is within ± 5% of its nominal flow rate.

The Lee Company has developed the Lohm Laws for defining and measuring resistance to fluid flow. The Lohm is defined such that 1 Lohm will flow 100 GPM of water with a pressure drop of 25 psi at a temperature of 80°F.
Always verify flow calculations by experiment.
