A serum pump, also called a treatment pump, dispenses a small, measured dose of a thin formula: typically 0.12–0.25 ml per stroke. We manufacture serum pumps in 18/410, 20/410 and 24/410 neck finishes as part of the bottle set they ship with, so the pump and the bottle share one color reference, one sample round and one lead time.
A serum pump, also called a treatment pump, is a dispensing pump engineered for low-viscosity formulas and small doses. Where a lotion pump delivers 1.0–2.0 ml for a hand or body application, a serum pump meters a fraction of that: the amount a concentrated serum, essence or facial oil is designed to be used at. It is built from five parts, each specified to the bottle.
The standard specification, and what we tailor for each program. Output, neck finish and dip tube are confirmed against your formula and your bottle at the sampling stage.

| Dip tube | Cut to the bottle's internal height | For glass and plastic bottles alike |
| Collar finish | Molded color | Frosted, spray-coated, electroplated, anodized aluminum |

The neck finish is written as two numbers. The first is the outside diameter of the thread in millimeters; the second is the thread style. All three serum finishes are 410, about one and a half turns of thread, so the choice is about diameter, and it follows the bottle.
Choose a neck finish
A slim neck for smaller bottles and narrow silhouettes, where a wider collar would look heavy on the bottle.
One of the most widely used treatment-pump finishes, and a flexible choice across common serum bottle sizes.
A wider collar with more presence, and the same finish lotion pumps use. Specify the serum on 24/410 and a whole range, serum and lotion, can share one neck finish and one collar design.
Both numbers must match. An 18 mm pump will not fit a 20 mm neck, and a 400 thread will not seat correctly on a 410 neck of the same diameter. That is why we specify the pump and the bottle together.
The output decides how many doses the bottle holds, and how long the routine lasts before a reorder. For a concentrated serum it is a formulation decision as much as a packaging one.
Bottle size
Output per stroke
Strokes = fill volume ÷ output per stroke. A dip-tube pump leaves a small residue at the base of the bottle.
Doses per bottle
Every output option for the selected bottle:
The dose for face and neck, and the standard range for a serum pump.
A smaller area and a more concentrated formula favor the bottom of the range.
Oils, foundations and concentrated actives move up to half a milliliter.
They belong in an airless system rather than on a dip tube. See the viscosity guide on our pumps page.
Send us the formula and the target dose, and we size the pump against the real product during sampling.
Both dispense a measured dose; they differ in how the formula reaches the actuator and how it is protected on the way. For oils dosed by the drop, a push-button dropper is the third route.
Draws the formula up through a dip tube cut to the bottle's height.
Dispenses 0.1–0.5 ml as a piston inside the bottle rises, holding the dose constant as the bottle empties.
A glass pipette with a push-button top, for oils and serums measured in drops rather than strokes.
The actuator and collar are the most visible part of a serum bottle, and every surface on them can be specified, matched to the bottle they ship with.

Where recyclability is part of the brief, a serum pump can be specified with PCR resin and in a mono-material build. A conventional pump combines several plastics with a metal spring; a mono-material design replaces the spring with a plastic one, so the whole pump belongs to a single material family.
Pair it with a PCR bottle for a set designed for recycling from the start. The route is specified per project, against your formula and your target market.

Tooling and shipping
The questions buyers ask most before they specify a serum pump. If yours is not here, send it with your formula and we will answer it against the real product.
Ask about your serum pumpA serum pump, also called a treatment pump, is a dispensing pump designed for thin formulas and small doses, typically 0.12–0.25 ml per stroke. It combines an actuator, a threaded collar, a pump engine, a dip tube cut to the bottle's height and a clear overcap, and is used for serums, essences, eye treatments and facial oils.
Most serums and essences sit at 0.12–0.25 ml per stroke; eye treatments favor the low end, and facial oils and richer actives move up to 0.5 ml. A 30 ml bottle gives about 150 strokes at 0.2 ml. We confirm the output against your actual formula during sampling.
The neck finish follows the bottle. 18/410 suits slim bottles and narrow silhouettes, 20/410 is a flexible middle choice across common serum sizes, and 24/410 matches the finish lotion pumps use, so a serum and a lotion in one range can share a collar design. The diameter and the thread must both match the bottle exactly.
A standard serum pump with a dip tube suits thin, stable serums and oils, in glass or plastic bottles. An airless pump dispenses 0.1–0.5 ml as a piston rises inside the bottle, without a dip tube, and is the specification for oxidation-sensitive actives, preservative-reduced formulas and thicker serums.
Yes. The actuator, collar and overcap are matched to the bottle from a physical color sample, and the collar can be frosted, spray-coated, electroplated in chrome, gold, rose gold or brushed, or finished in anodized aluminum.
A serum pump dispenses a liquid dose, not a spray. For fragrance, body mists and toners, the right dispenser is a fine mist sprayer, which atomizes 0.08–0.15 ml per spray. See our fine mist sprayers.
MOQ is 10,000 units per SKU on existing molds. A pump head sample takes 15–18 days in a stock color and 15–25 days in a specified color; production of 10,000 custom-color pump heads takes 30 days, counted from receipt of vector artwork and payment. Sea freight adds 35–40 days.
