How do I choose a nozzle or discharge for essential oil?
Choose the outlet around product behaviour, the smallest pack opening and the clean cutoff required. For essential oil, the nozzle must handle is low volume, high value, aromatic and may attack unsuitable materials while entering or approaching small glass bottles with droppers without splash, blockage, foam or pack contact.
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.
- Measure the smallest internal opening and shoulder clearance of small glass bottles with droppers.
- Record the largest particle, string length or foam tendency where relevant.
- Check whether bottom-up filling or positive shutoff is required.
- 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 bore is too small or too large for the product and required flow.
- The nozzle closes too slowly or retains product after cutoff.
- Pack tracking allows the opening to miss the nozzle centre.
- 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 alternative bore, tip and shutoff geometries.
- Control nozzle height and motion against the actual pack.
- Add drip capture only after the root cutoff issue has been addressed.
- 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 Essential oil
- All relevant small glass bottles with droppers
- 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 essential oil?+
Measure the smallest internal opening and shoulder clearance of small glass bottles with droppers.
Why does this problem happen with essential oil?+
The bore is too small or too large for the product and required flow.
How can I improve or correct the problem with essential oil?+
Trial alternative bore, tip and shutoff geometries.
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 Essential oil; All relevant small glass bottles with droppers; Target fill and tolerance; Required accepted output. Representative production samples and a measurable acceptance target are normally more useful than a catalogue description alone.
