Treatment Pump 18/415 Ultra Fine 0.2cc Lotion Dispenser Pump Serum Bottle Set

When a single 30ml bottle of serum contains thirty euros of peptide concentrate, dosage accuracy stops being a comfort feature and becomes a cost control. This 18/415 Treatment Pump is metered at 0.2cc per stroke with a tolerance of plus or minus 0.02cc, which means a hundred strokes deliver hundred doses rather than ninety four, and the brand can calculate fill weight against usage with confidence.

The outlet is machined as a fine annulus rather than a standard nozzle, so the product leaves as a controlled bead that drops onto the fingertip instead of splashing. For watery essences and oil blends that thin bead is also what prevents the pump from drawing air back through the nozzle and oxidising the actives between uses.

• Overdosing expensive actives because a standard pump delivers 0.3cc where the label claims 0.2cc, silently raising cost of goods.
• Splashing and dripping from a wide nozzle that wastes product and stains the bottle neck.
• Air drawn back through the outlet accelerating oxidation of vitamin C and retinol formulas.
• Pumps too tall for a 30ml dropper style bottle, forcing a package redesign late in the project.

• 0.2cc Metered Stroke: Chamber volume is tooled to a 0.02cc band, so a hundred strokes equal a hundred doses and fill planning stays predictable.
• Fine Annulus Outlet: Product leaves as a controlled bead onto the fingertip rather than a splash, cutting waste on high value formulas.
• Anti Draw Back Valve: A silicone check valve at the outlet stops air re-entering the bottle, slowing oxidation of actives between applications.
• Low Profile Head: Overall height of 62 mm fits 30ml and 50ml serum bottles that standard treatment pumps overhang.
• Glass And PET Ready: 18/415 thread is tooled for both glass and PET necks, with a soft gasket option for thin glass rims.
• Batch Traceability: Each carton carries a mould cavity code so any dosage deviation can be traced to a single tool.

Used for facial serum, essence, ampoule, cuticle oil, hair growth tonic and spot treatment packaging. The 18/415 neck matches the slim 30ml and 50ml glass bottles that dominate the premium skin care shelf, and also fits PET alternatives for travel sizes. Contract manufacturers filling actives in small batches appreciate the fine dosage because trial runs can be planned by stroke count instead of by weight, and brands appreciate that the low profile head keeps a 30ml bottle inside a standard retail carton.

One thousand pumps ship per carton at 48 x 36 x 32 cm with tube protection trays. Because the product serves small fill volumes, orders start at 3,000 pieces, and mixed neck finishes can be combined in a single shipment. Neutral colour stock is ready in 12 working days with custom colour at 25 days. A sample kit containing three dosage variants and both tube diameters is available so formulators can match the pump to a specific serum viscosity before the artwork is frozen.
