Label applicator for vials and small glass bottles
This LINEVO configuration labels small-diameter pharmaceutical containers. Applications include glass vials, ampoules and small medical bottles for pharmaceutical, biotech and injectable production. Configuration review covers a servo-driven synchronous conveyor and a V-block stabilization system that keep small vials steady during labeling, soft-pressure rollers that press the label onto curved glass, an interface for batch coding and vision detection, and tool-less mandrels for changing vial diameter. Our engineers define the required handling, coding and inspection arrangement for your line.
How is a vial labeled automatically? In a typical arrangement, vials arrive upright from a filler or unscrambler, are spaced on the conveyor and held by guides. A sensor triggers the label head, the leading edge of the label meets the vial, and the vial is rolled so the label wraps around the body while rollers press it down. Batch and expiry data are usually printed on the label just before it is applied, and a camera can check the result before the vial leaves the machine. The feeding, transfer and reject arrangement for your line is confirmed in the quotation.
Small vials and containers: what to check
The smaller the container, the less label surface and stability it offers. These points decide whether a vial can be labeled reliably on this configuration and which format parts it needs.
| Item | Why it matters | What to send |
|---|---|---|
| Diameter and height | Small, light vials tip over easily, and each diameter needs its own guides or mandrel | Samples of the smallest and largest vial in your range |
| Container shape | The label needs a cylindrical zone; ampoule necks, shoulders and tapers limit where it can go | A drawing with the label zone marked |
| Closure | Stoppers, crimp caps and flip-off caps change the vial height and how the vial can be held | Capped samples, as they arrive at labeling |
| Label | Small labels carry dense text; label size, material and overlap decide how the label wraps | Label specification, artwork and roll details |
| Printed data | In-line printing needs a printer and label stock that suit each other and a free print area | The data fields, the printer type if you already have one, and the print area |
| Surface condition | Cold vials or condensation can reduce label adhesion | The temperature and condition of vials at labeling |
Vial labeler, ampoule labeler or labeling line?
LINEVO lists three configurations for small pharmaceutical containers. Choose by the main container and by how much of the line the labeling must connect to.
| Configuration | Container formats | Start here when |
|---|---|---|
| This configuration | Glass vials, ampoules and small medical bottles | Vials and small glass bottles are the main format and you need a stand-alone labeler |
| Ampoule labeling machine | Glass vials, ampoules and test tubes | Ampoules or test tubes are the main format |
| Pharmaceutical labeling line | Vials, ampoules, infusion bottles and medicine boxes | Labeling must run with filling upstream and cartoning downstream, with batch coding and code verification on one line |
Vial labeling questions
Can it label peptide vials? For peptide vials, we review the capped glass vial and label together. Diameter, height, closure and label dimensions determine the handling and labeling arrangement.
Can it print and verify lot and expiry data? Configuration review includes interfaces for ink-jet or thermal-transfer printing and vision checks of label presence, print quality and batch or expiry data. State which data must be printed and checked, confirm whether the printer and camera are included, optional or supplied by another party, and agree how failed vials are rejected.
What placement accuracy can I expect? We establish placement tolerance with your vial and label and define the measurement method during engineering review.
What output and vial size range does it cover? Our engineers define output and the vial-size range around your containers, labels and coding arrangement.
What should I send for a quotation? Capped samples of each vial size, the label specification and artwork, the data to print, the target vials per minute, the upstream filler or unscrambler and the downstream equipment, and site utilities.

How this fits the Automatic Labeling Machines process
Labeling machines apply self-adhesive labels to bottles, jars, cans or boxes as they pass along a conveyor. Container shape, label positions and coding or inspection options define the scope of a configuration.
This machine is part of our Automatic Labeling Machines portfolio. Explore the configurations for other products and pack formats, or discuss a tailored arrangement with our engineering team.
This configuration is also listed on a page that compares the options for the same kind of product or machine.
The linked guides explain how this type of machine works and how to choose one.
