Does a 24/410 Lotion Pump Fit Your Bottle?
Use nominal neck sizes to shortlist pumps, then confirm the housing, sealing surface and assembled bottle before ordering.
Read the guideTHE STDPAK BUYER GUIDES
A pump that fits. A spray that suits the formula. A stopper you can approve with confidence. Start with the question holding up your packaging decision.
236 practical guides. Six buying topics.
Drawings, samples and agreed specifications come first.



WHERE ARE YOU IN THE ORDER?
No need to read the whole library.
I am choosing a component
A nominal neck size is useful. It is not a fit approval.
I have a dispensing problem
Leaks, poor priming and a weak spray need different checks.
I am ready to request samples
Record the assembly, liquid and approval criteria before ordering.
SIX BUYING TOPICS
Browse by component, or go straight to the purchasing questions that affect every order.

Neck fit, output, locking, tube length and sample approval.

Screw or crimp, spray pattern, cap clearance and priming.

Formula disclosure, materials, leaks and compatibility trials.

Output, chemical fit, shipping leakage and in-use handling.

Bore fit, stopper choice, insertion and printed-lid approval.

RFQs, comparable quotes, pilot runs, inspection and paperwork.

PUT THE GUIDANCE TO WORK
Keep the numbers and the buying brief together. These tools run in your browser; nothing is sent to STDPAK.
Weigh the collected liquid after priming. Enter the net mass, number of full strokes and formula density to estimate volume per stroke.
This is an average, not a pass/fail test. Use the agreed sampling method, stroke technique and acceptance limits. Repeat runs to see variation; do not assume density is 1 g/ml.
How to compare output measurements ↗A product photo is a starting point. Add the details that make two quotations comparable.
SOME QUESTIONS NEED THE ACTUAL SAMPLE
A guide can narrow the options. A final recommendation still needs the bottle, formula, selected component and the conditions in which it will be used.
