Dosing principle
Peristaltic pumps suit sterile and small liquid fills, pistons suit thicker liquids, and screw or auger dosing suits powders.
No DramaBuyer guide · Lab & process
A pilot filler changes product and container every week, so what you pay for is accuracy at your smallest fill and the time it takes to change over, while listings sell speed.

01
Peristaltic pumps suit sterile and small liquid fills, pistons suit thicker liquids, and screw or auger dosing suits powders.
A percentage means little without the fill size and speed behind it.
Tube, steel grade and seals that touch product, with certificates.
Tooling per container, time to swap it, and whether the unit also stoppers, caps or crimps.
02
Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.
03
| Require this | A pass looks like |
|---|---|
| Fill a counted run of your product at your smallest fill and weigh each one. | Mean and spread of fill weights inside the tolerance in the order. |
| Change to your second container and product while timed. | Done inside the offer's stated time, first fills in tolerance. |
| Run through closing or capping on the same run. | Every container closed and seated, no reject left in the output. |

05
A production filling line, where speed matters more than changeover.
A calibrated benchtop dispenser or a balance and pipette, until volume justifies a machine.
06
We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.
07
Every machine we source in this area is on the Lab & process page. How a project runs, stage by stage, is on how it works, and what it costs is on pricing.
Straight answers
Compare fill weight spread on your product at small fills, and the contact-part papers, not speed.
Serial against the declaration, weighed fills at both ends of the range, changeover time and contact-part certificates.
A Declaration of Conformity for that serial number and a technical file behind it. The machine is never GMP compliant on its own; the buyer qualifies it.
The business placing it on the EU market, usually the buyer, who checks the conformity file.
