Inquiry

Quartz nozzles machined to a defined inlet, taper, and orifice — where the flow path geometry is the actual function, not just an OD and length.

Inlet size, taper angle, and orifice diameter are one coupled flow path, not separate dimensions — a given taper angle and length fixes the relationship between inlet and orifice size, so you can't specify all three independently. Confirm which two are fixed by your process and let the third follow.

Quartz Nozzle Tip and Orifice Designs

Nozzles are drawn from tube or capillary blank stock down to a tapered tip, then cut and finished at the orifice. Orifice diameter is the dimension most often pushed to its limit — a very fine orifice narrows the achievable concentricity and increases sensitivity to any asymmetry in the taper.

The table above is what's repeatable without added lead time. Minimum orifice and tightest concentricity aren't both available at once — the finer the orifice, the more that constrains how precisely it can be centered on the inlet axis. Flag which matters more for your application.

Taper, Flow Path and Concentricity

Concentricity between the orifice and the inlet axis determines whether flow exits straight or at an angle — a nozzle can hit its orifice diameter spec and still misdirect flow if the taper isn't centered. Where the orifice is drilled rather than drawn to size, mechanical or diamond drilling holds openings down to about Ø0.8 mm at ±0.02 mm. Before shipment we check inlet dimensions, taper, orifice diameter, concentricity, overall length, and tip condition.
