It is the chamber volume: 1.0 ml leaves the nozzle on every full stroke, with a tolerance of about ±0.1 ml. It is the smallest dose in our range — chosen when a 2.0 ml pump would over-apply toner, serum or eye product.
What is an outer-spring pump?
The spring sits outside the fluid chamber instead of inside it. The formula only touches PP, which suits acids, high-pH gels and actives that react with metal, and it lets the spring be separated cleanly for recycling. It is also the reason the collar looks taller than an inner-spring version.
Which bottles suit a 1.0 ml dose?
Facial toner, essence, serum and eye-care bottles from roughly 30 ml to 150 ml on a 24/400 neck. For a body lotion or shampoo, a 2.0 ml or 4.0 ml pump gives a more natural dose per use.
Can the dip tube be cut to my bottle height?
Yes. Dip tubes are cut to the bottle height you specify, so a 30 ml or 50 ml bottle gets a short tube that reaches the base without curling. Send the bottle drawing and we will match it.
What is the MOQ?
Black and white models start at 10,000 pcs per model and closure finish; custom Pantone colours start at 30,000 pcs. Stock samples are free for qualified projects.
