Part of Washing & Cleaning.
Start a bottle-washer enquiry with the container, the required cleaning result and the condition needed at the next process. Then compare handling, washing media, utilities and the evidence each supplier will provide. Machine speed and the number of wash stations are only parts of that decision.
1. Define the cleaning duty before choosing a platform
Record the incoming container material, geometry, lot and condition. Identify the contamination or residue to address, the assessment method and the next operation. An oral-liquid bottle, an injectable vial and an ampoule need their own process and format review; nominal capacity alone does not identify the duty.
What the machine contributes
A washer presents an approved container to a defined cleaning sequence. Its handling parts, nozzles, media supply and discharge arrangement must work together. The enquiry should distinguish handling without damage, the measured cleaning result and the condition of the container after transfer.
Keep cleaning, sterilization and depyrogenation separate
| Operation | Question to resolve | Evidence boundary |
|---|---|---|
| Washing / cleaning | Which particles or residues must be removed, from which surfaces? | Approved challenge, sampling and assessment at the stated wash conditions. |
| Sterilization | What separately defined process establishes the required microbial outcome? | A washing stage or clean appearance does not by itself establish sterility. |
| Depyrogenation | What process and evidence establish the required pyrogen/endotoxin result? | A WFI connection or generic wash recipe is not proof of that result. |
2. Shortlist by container handling and process
Use the bottle-washer comparison for published HM arrangements, then supply drawings and representative samples. Confirm the offered format scope in the proposal.
Compare the arrangement, not a universal “best” type
| Arrangement to discuss | Handling questions | Process and scope questions |
|---|---|---|
| Operator-assisted rotary washing | Who loads, holds and removes each container, and at which points? | Which wash steps, operator duties and complete-batch output are included? |
| Linear bottle washing | How is the bottle supported and transferred through the selected stations? | Which approved formats, change parts, media stages and discharge conditions apply? |
| Rotary gripper washing | Which neck/body dimensions govern gripping, inversion and transfer? | What handling and cleaning evidence covers the requested format range? |
| Air-jet cleaning | How are containers presented and loosened debris removed? | Does the defined dry-cleaning task meet the actual requirement, or is wet washing needed? |
Do not choose solely from a broad description such as compact, automatic or high output. Review the infeed and format checks. For injectable containers, use the separate ampoule and vial format guide.
3. Follow the container and media through the proposed machine
For the selected arrangement, mark infeed, spacing, holding/inversion where applicable, each media stage, drainage and outfeed on the supplier's drawing. Ask what prevents a mispositioned container from being processed and how an interrupted sequence is handled. The drawing should identify supplied functions and remaining buyer responsibilities.
Review the parts that establish the result
- Container path: guides, pockets or grippers, timing parts, nozzle clearance and transfer support.
- Media path: source, tanks, filters, pumps, manifolds, nozzle connections, returns and drains included in the order.
- Controls: which values are set, displayed, measured, alarmed or recorded; which stop conditions and interlocks are included.
- Access: safe cleaning and maintenance access, removable parts and their identification.
The change-parts guide covers the installed interface information needed for format-specific tooling.
4. Define water, air and drainage at the machine boundary
Identify each water stream by its approved quality requirement and use. Keep recirculation history, treatment terminology and pharmaceutical water grade distinct. Do not assume that a demineralized supply and a specified pharmaceutical Purified Water supply are interchangeable simply because both remove dissolved ions.
For parenteral glass-container preparation, the FDA aseptic-processing guidance, section VI.B.1, recommends that final-rinse water meet WFI specifications. Apply that reference within its stated scope; it is not a universal instruction to add WFI to every bottle-washing application.
| Record | What to confirm |
|---|---|
| Water stream | Quality specification, source, temperature, pressure/flow requirement, monitoring point and permitted return route. |
| Compressed air | Required quality, pressure/flow, point-of-use treatment and responsibility for demonstrating suitability. |
| Drain and return | Destination, segregation, backflow prevention and available capacity for the agreed operating modes. |
| Consumption | Mode, duration, measurement boundary and whether the value is estimated or measured. |
Continue with the wash-media and cycle guide and the mode-by-mode consumption record. Neither a water label nor a utility nameplate replaces performance evidence.
5. Agree trial evidence and sample custody together
Before the trial, name the product/container formats, configuration, operating conditions, checks and acceptance criteria. Separate a supplier demonstration or FAT from the buyer's site qualification and process-validation responsibilities. Use the existing washing FAT checklist and worksheet to organize the agreed coverage.
Assign sample custody within the trial plan
| Stage | Record before interpreting a result |
|---|---|
| Incoming sample | Lot, format, sample ID, incoming condition and challenge preparation, if applicable. |
| Machine run | Configuration, recipe/settings, utility condition, run stage and interruptions. |
| Collection | Sampling location, time, collector and handling/storage conditions. |
| Assessment | Method, laboratory or assessor, result reference, limitations and authorized decision. |
Keep mechanical observations separate from analytical results. A bottle can transfer smoothly while the cleaning result remains unassessed. Conversely, an acceptable sample result does not approve untested formats, waiting times or utilities.
At the site, verify the installed arrangement, utilities and interfaces against the approved scope. Record deviations and the evidence needed to close them. Define which changes, repairs or adverse trends require further assessment rather than assigning a generic revalidation interval from this article.
6. Turn the review into an orderable requirement
A compact washer requirement record
| Requirement group | Decision to record |
|---|---|
| Format and duty | Approved drawings/samples, intended use, cleaning objective and required output at the agreed endpoint. |
| Process and utilities | Media sequence, quality requirements, operating ranges, source/return boundaries and site obligations. |
| Handling and line | Included format kits, infeed/outfeed condition, stop/restart ownership and waiting-container disposition. |
| Acceptance and documents | Trial coverage, sample custody, decision criteria, drawings/manuals and specifically ordered records. |
Close gaps before comparing price
A maximum speed without the tested format, a format range without included parts and a general GMP claim without a defined deliverable are incomplete comparison points. Ask for written answers and retain unresolved items. Use the quotation comparison guide to compare equivalent scope.
Compare costs over the same boundary
Separate machine supply, format kits, integration, utilities, testing, site work, consumables and service. Use actual offers and a stated operating pattern. Avoid subtracting speculative productivity savings from a purchase price or treating connection capacity as daily consumption.
7. Match regulatory and capability questions to the project
The buyer's quality team should identify the requirements applicable to the product, process and intended market. For US drug-product containers, 21 CFR 211.94 addresses cleanliness, required treatment and written specifications/methods. For sterile manufacture, EU GMP Annex 1 places equipment and process controls within a facility contamination-control strategy. These references do not certify a machine or establish the buyer's compliance.
The WHO TRS 1033 report includes guidance on pharmaceutical water and data integrity. Keep applicable requirements connected to the approved site specification and the supplier's agreed deliverables.
Review optional capabilities against an actual need
Ask whether the proposed machine includes the required recipes, protected settings, utility monitoring, records or line signals, and how each function will be demonstrated. Camera functions, advanced analytics and electronic records must be specifically scoped. Their appearance in an industry discussion does not mean they are standard HM features or a verified technology trend.
Plan routine care and change control
Agree the machine-specific maintenance, calibration, cleaning, spare-parts and backup instructions at handover. Authorized personnel should follow the supplied manual and site isolation procedures for hands-on work. Record changes to formats, nozzles, media, software or downstream interfaces and assess whether existing evidence still applies.
Frequently asked questions
Should I choose linear or rotary washing from the advertised speed?
No. First confirm container handling and the required cleaning task, then compare demonstrated output, format parts, utilities and line interfaces under the same conditions.
Does WFI or a wash cycle prove sterility or depyrogenation?
No. Water quality, washing, sterilization and depyrogenation are distinct requirements. The intended process result needs its own approved method and evidence.
What belongs in a washer trial record?
Identify the container lot and format, configuration, media conditions, operating stage, sample custody, assessment method, results, limitations and acceptance decision.
Are all listed controls and documents included with a machine?
Only the scope accepted in the current proposal should be treated as included. Confirm each function, format kit, document and test with its delivery and acceptance responsibility.
