Example build · Precision filler
Fills by weight, not by guess.
A single-station benchtop filler that sits the container on a load cell and closes the last fraction of the fill with a trim pump, so what leaves the machine is what the label says.
Specifications
- Fill range
- 15 ml - 1 L
- Accuracy
- Plus or minus 1% of target fill weight, and never more than plus or minus 5 g on any single fill, verified against your own scale at commissioning. Under 60 ml, fill accuracy depends on fill speed and product viscosity; the achievable figure is confirmed against your actual product during the sample fitting.
- Throughput
- Capacity and rate configured to your container and fill volume, quoted per build
- Power
- 120 V standard wall outlet
- Lead time
- 4 weeks
- Price range
- $3,750 - $14,950
Why 60 ml is the line
Below roughly 60 ml the fill is short enough that pump start-and-stop behaviour and the way your product flows start to dominate the result. For reference, the US net-content rules in NIST Handbook 133 allow an individual 60 ml package to vary by 3.8 ml, about 6%, and a 30 ml package by that same 3.8 ml, about 13%. The EU average-quantity system allows 9% below 50 ml. A 1% target is an order of magnitude tighter than either, which is why we confirm it on your product rather than promise it on a page.
Ranges reflect builds completed to date. Your quote comes after we have had your container on the bench.
Volumetric fillers assume your product behaves the same way every time. Thick, foaming, settling and temperature-sensitive products don't. Filling on a load cell removes the assumption: the machine watches the actual weight in the container and stops when it gets there, then trims the remainder slowly so the last few grams land accurately instead of overshooting.
That matters most when the product is expensive. Giving away a percent per unit on a coating, a concentrate or a supplement is a real cost across a run, and being under is worse than being over. Accuracy is dialled against your own scale during commissioning, with your own product, so the number you verify is the number you keep.
The unit is built around your container. Tooling holds the specific bottle you use, the nozzle is picked for how your product actually flows, and the whole machine runs off a standard 120-volt wall outlet on a bench — no compressed air line, no three-phase drop, no electrician.
If you want to know whether your bottle works on this platform, the fastest answer is to send us two or three of them.
