Dose control
The dosing technology must give useful resolution and repeatability at the minimum fill, not only at the top of the range.
Bottle filling applications
Pharmaceutical & Small-Dose Bottle Filling
Small-dose and regulated applications need precise pack handling, a defined product-contact path and a clear validation strategy; machine suitability depends on the process standard required by the user.
Application engineering
Build the specification around the production product
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.
- Minimum, maximum and nominal dose
- Required repeatability and verification method
- Liquid viscosity and tubing/material compatibility
- Bottle neck, stopper, dropper and closure samples
- Cleaning, sterilisation or disposable-path expectations
- User-defined documentation, calibration and validation scope
Pharmaceutical & Small-Dose Bottle Filling. The recommended configuration will be matched to your product, container, fill range and required output.
Application risks
Four issues to resolve before machine selection
These factors often decide the filling principle, nozzle design, cleaning route and automation level.
Product-contact path
Tubing, nozzle, tank and feed components should be documented and compatible with the product and cleaning method.
Small pack handling
Vials and narrow-neck bottles may need pucks, nests, star wheels or neck support to remain stable.
User validation
The end user must define the applicable quality system, validation documents, calibration and acceptance requirements.

Questions
Pharmaceutical & Small-Dose Bottle Filling FAQs
Application-specific answers for early project planning.
Is every peristaltic filler suitable for pharmaceutical production?
No. The machine and documentation must be assessed against the user’s process, quality and regulatory requirements. A general-purpose machine should not be assumed to meet a regulated standard.
Why use peristaltic filling for small doses?
It can provide electronic dose control with the product contained in selected tubing, simplifying the wetted path for suitable liquids.
How are tiny bottles kept stable?
Bottle nests, pucks, neck guides or dedicated indexing parts can hold small containers in a repeatable position.
Can calibration documents be supplied?
Calibration and documentation scope should be defined in the quotation and acceptance plan. The user should specify required standards and traceability.
