Chemical compatibility
The full wetted path—including tanks, pumps, hoses, seals, valves and nozzles—must be checked against the formulation.
Bottle filling applications
Chemical and cleaning products can combine foam, corrosion, fumes, variable viscosity and challenging closures, so product-contact and operator-safety requirements must be set early.

Application engineering
A laboratory viscosity or marketing description is not enough. The filler should be reviewed using product at the normal process temperature, representative bottles and the planned supply method.

Application risks
These factors often decide the filling principle, nozzle design, cleaning route and automation level.
The full wetted path—including tanks, pumps, hoses, seals, valves and nozzles—must be checked against the formulation.
Surfactants can foam heavily; aggressive liquids may also require enclosure, extraction or controlled nozzle movement.
Flammable or solvent-based products require a separate hazardous-area assessment; chemical resistance alone is not ATEX compliance.
Bottles, caps, liners, triggers and labels must tolerate both the filled product and any neck residue.
Recommended starting routes
The table is a shortlist for discussion; trials and detailed engineering determine the final machine.

| Corrosive liquids | A compatibility-led chemical filling system with suitable product-contact construction. | Explore route |
| Oils and automotive fluids | Pump or volumetric filling selected around viscosity and clean cut-off. | Explore route |

Questions
Application-specific answers for early project planning.
Not by assumption. Compatibility varies with formulation, concentration, temperature and exposure. Every wetted component should be reviewed.
Flow profiling, diving nozzles, appropriate nozzle bore, stable product supply and enough fill time can reduce foam. The actual formulation should be trialled.
No. ATEX is relevant where an explosive atmosphere may be present and the applicable assessment requires compliant equipment. Many corrosive but non-flammable products present different hazards.
Yes. Trigger and pump feeding, orientation, insertion and tightening can be integrated, subject to closure trials and output requirements.
Send product data, representative bottles, closures, fill range and output. Lancing Ltd can identify the most credible filling route.
Bottle and pack evidence
The product, wetted parts, bottle, closure, labels and cleaning route need a consistent compatibility review. Supply current safety information and representative packs before final selection.
Document product concentration, temperature and known effects on tubing, seals, bottle and closure materials.
Define nozzle cut-off, drip collection, spill response and what happens to a bottle after a fault or incomplete fill.
Check flexible containers, trigger bottles, jerrycans and unstable shapes through filling, capping and labelling.
Include every bottle and closure that is expected to run, not only the easiest format. Note the normal product condition, fill range, batch pattern and the clean presentation required at the next process.

Pack and product extensions
Foaming surfactants and heavier multi-litre packs can require different nozzles, product supply, handling and closure controls.
Review foam, air, diving nozzles, staged flow and trigger or pump closures.

Chemical filling projects should confirm product compatibility separately from machine handling. The same bottle also needs to remain stable through guides, filling, capping and conveyor transfer.
