Small-pack stability
Narrow conveyors, close transfers and controlled spacing help lightweight cartons, bottles and medical packs cross the weigh section consistently.
Controlled, repeatable inspection
Pharmaceutical checkweighers for high-value, tightly controlled packs
Verify carton, bottle, device and kit weight without relying on periodic manual samples. A correctly engineered checkweigher may flag missing-content or component-count errors when the gross-weight difference is distinguishable, while supporting controlled recipes and secure reject handling.
01Compact product handling
02Controlled user access options
03Secure reject architectures
System design
Weight inspection aligned with regulated production
Lightweight regulated packs require controlled presentation, protected recipes, secure non-conformance handling and records defined around the customer’s quality process.
Recipe protection
Product settings, target weights and limits can be protected by access level to reduce the risk of unauthorised changes.
Secure non-conformance handling
Lockable reject bins, reject confirmation, bin-full sensing and fail-safe line responses can be incorporated where the risk assessment requires them.
Data for review
Batch totals, weight statistics, reject events and operator actions can be made available for production review, subject to the selected control and software package.
Specification
Important pharmaceutical project questions
- Can gross weight reliably distinguish the missing component?
- What is the permitted product and packaging variation?
- Which user roles may create, edit or run recipes?
- What batch, audit and electronic-record data is required?
- How must rejected packs be contained and reconciled?
- Are validation support, IQ/OQ documentation or test protocols required?
- Which line devices must exchange status and fault signals?
Line integration
Weight can complement, but not replace, product verification
Gross-weight inspection is powerful when the missing item produces a detectable weight difference. It is often combined with barcode reading, label inspection, code verification or vision inspection to confirm identity as well as quantity. We help define which risks are best detected by weight and where another inspection technology should be added.

Combine weight with barcode, label and product verification
Weight can support completeness checks while barcode and vision systems directly verify identity, visible components, labels and printed information.

Questions about pharmaceutical
These answers set practical boundaries around missing-item detection, user access, reject containment, electronic records and validation support.
Can a pharmaceutical checkweigher detect a missing leaflet?
Potentially. Detection depends on the leaflet weight compared with normal variation in the product and packaging. Representative samples and a capability trial are the safest way to confirm the inspection window.
Is 21 CFR Part 11 functionality available?
Audit, access and electronic-record requirements must be defined project by project. We can specify control and data options around your URS, including relevant 21 CFR Part 11 and Annex 11 considerations where required.
Can rejected cartons be locked away?
Yes. Lockable reject containment, reject confirmation and controlled removal procedures can form part of the agreed system design.
Do you support validation?
Validation documentation and IQ/OQ support can be scoped where required. The deliverables, responsibilities and acceptance tests should be agreed before manufacture.

Cartons
Use in-line gross weight as a fast, non-destructive indicator of product completeness. From small pharmaceutical cartons to food, cosmetic and general-manufacturing packs, the system is configured around the detectable weight difference and the normal variation of every pack component.

Production data
Make weight inspection information useful beyond the machine HMI. From simple batch reports to line-level data exchange, we define the records, identifiers, retention and interfaces your production and quality teams actually need.

Reject systems
A weight result only protects production when the correct item is removed and its removal is confirmed. We select the reject principle around pack behaviour, throughput, available length and the way your quality team needs to contain and reconcile non-conforming product.
