How Does the Triple-Chamber Airless Dropper Work?
Unlike traditional pipette droppers, UKPACK’s triple-chamber airless dropper uses an inverted, push-to-dispense mechanism. Simply point the precision tip downward and press the bottle’s base to dispense three separately stored formulas through a single outlet.
- Invert the Bottle: Hold the bottle upside down with the precision dispensing tip facing downward.
- Press the Base: Press the bottle’s base to activate the spring-loaded pump mechanism.
- Dispense Three Formulas: Each chamber delivers a nominal 0.12ml per stroke, providing a combined output of 0.36ml.

Three Formulas. More Skincare Possibilities.
From multi-active serums to oil-and-emulsion combinations, UKPACK’s triple-chamber airless dropper gives skincare brands the flexibility to store three formulations separately and dispense them together through one precision tip.
Formula compatibility, viscosity, and dispensing performance should be evaluated with the intended formulations before production.
