Which filling machine is best for cosmetic serum?
The best starting point is a gravity, pump, flow, level or volumetric route selected from dose range, accuracy, pack and required output. Confirm it by trial because cosmetic serum is is low viscosity, often high value and filled in small doses, and the route must also suit dropper bottles, vials or airless packs, the fill range, cleaning regime and required good output.

What should I check first?
Record the machine state and the finished result before changing settings. This helps identify where control is first being lost.
- Confirm the production condition of cosmetic serum: is low viscosity, often high value and filled in small doses.
- Measure the limiting pack details for dropper bottles, vials or airless packs, including opening, stability and fill range.
- Check that product reaches the machine through a clean low-volume pump or peristaltic supply.
- Record ten consecutive fills by weight and note the product temperature, density or batch condition.
- Confirm the product supply remains stable at minimum and maximum hopper or tank levels.
Why is this production problem happening?
Work from the evidence and change one variable at a time. These are the most relevant causes to investigate first.
- The selected method does not accommodate that cosmetic serum is is low viscosity, often high value and filled in small doses.
- Product condition changes between the sample, start-up and a sustained run.
- Pack tolerance or presentation is influencing the measured result.
- The dosing principle is unsuitable for viscosity, particles, aeration or accuracy.
- Product conditions are changing during the run.
How can I correct or improve it?
Make a controlled change, repeat the same measurement and compare the result before moving to the next adjustment.
- Trial cosmetic serum using representative production batches and the full pack matrix.
- Use a gravity, pump, flow, level or volumetric route selected from dose range, accuracy, pack and required output.
- Plan changeover around this requirement: use a validated small-batch cleaning and line-clearance procedure.
- Stabilise product temperature, mixing and supply before retuning.
- Test a representative product and pack matrix across the full fill range.
What should I send Lancing?
The most reliable recommendation is based on representative production materials and a measurable acceptance result.
- Representative sample of Cosmetic serum
- All relevant dropper bottles, vials or airless packs
- Target fill and tolerance
- Required accepted output
- Photographs or video of the current process
- Product name and a sample or SDS where relevant
- Viscosity, temperature, particles, foaming and density

What should I check first for cosmetic serum?+
Confirm the production condition of cosmetic serum: is low viscosity, often high value and filled in small doses.
Why does this problem happen with cosmetic serum?+
The selected method does not accommodate that cosmetic serum is is low viscosity, often high value and filled in small doses.
How can I improve or correct the problem with cosmetic serum?+
Trial cosmetic serum using representative production batches and the full pack matrix.
Which part of the production line does this question relate to?+
This question relates primarily to filling & dosing. It may also be affected by upstream product or pack supply and by downstream handling, so check the full production sequence rather than one machine in isolation.
What should I send when asking for a machinery recommendation?+
Send Representative sample of Cosmetic serum; All relevant dropper bottles, vials or airless packs; Target fill and tolerance; Required accepted output. Representative production samples and a measurable acceptance target are normally more useful than a catalogue description alone.
