Lateral Flow Dispensing Nozzles

IsoFlowTM Low Contact Pressure (LCP) Nozzle

IsoFlow LCP Nozzles are used to deliver a fine line of reagent to the membrane. The nozzles typically have larger inside diameters than non-contact type nozzles, which lowers shear stress on the fluid, allows lower dispense pressures and greatly reduces the chance of clogging and damage to reagents. The key to the LCP technology is the flexible nozzles. Variations in membrane thickness cause the nozzle to flex a little more or less so that contact with the membrane is always maintained. The contact pressure is so low that there is no significant mechanical stress on the membrane and no damage. A variety of nozzle geometries and materials are available. Minimum spacing between nozzles is 5mm with the standard nozzle holders.  Spacing down to 2mm can be achieved with custom holders.

IsoFlowTM Atomizing Nozzle

The IsoFlow Atomizing Nozzle is used when wide reagent lines are desired (primarily to dispense conjugates onto pads). The large inside diameter (250µm) of the nozzle allows for low delivery pressures and shear stress while minimizing clogging. It is ideal for use with viscous reagents. The atomizing nozzle can be used with the LCP nozzles so that all reagents are dispensed in one pass. The atomizing nozzle requires a clean compressed gas source (air or nitrogen) to create the aerosol. The nozzle requires approximately 2 SLPM (0.07 SCFM) of gas source at 15 to 20 PSI (1.0-1.3 bar).
