LINUO’s RTU glass vials provide a ready-to-use sterile packaging solution for high-end aseptic filling lines. Each vial is supplied washing-free, depyrogenation-free, and pre-sterilized, helping pharmaceutical manufacturers reduce in-house preparation, eliminate the need for additional WFI washing systems and depyrogenation tunnels, and lower CAPEX, floor space, and maintenance requirements.
Available in 2R, 4R, 6R, 8R, 10R, 15R, 20R, 25R, 30R, and 50R sizes, LINUO RTU sterile vials are compatible with mainstream automated filling machinery and support direct loading into sterile production workflows. The standardized RTU Nest & Tub and flexible RTU Tray formats are designed for smooth line integration, reduced machine downtime, and safe Grade A/B transfer.

RTU sterile vials are delivered washing-free, depyrogenation-free, and pre-sterilized, allowing customers to reduce preparation steps and move directly toward aseptic filling.
By bypassing WFI washing systems and depyrogenation tunnels, RTU vials help reduce capital investment, cleanroom floor space, equipment maintenance, and operational complexity.
Individual vial support can reduce vial-to-vial contact within the defined packaging configuration. Confirm the contact scope during unloading and line transfer, and record scratches, breakage and handling interventions during the SKU-specific trial.
Vacuum-sealed Tyvek® double breathing bags and clean-peel technology help prevent fibers or particles from entering the sterile zone, supporting clean Grade A/B transfer.
Assess each Nest & Tub or Tray configuration with the selected machine OEM, format parts and transfer method. Establish the acceptable operating range through a documented trial, recording actual throughput, stoppages, interventions and changeover performance.
The ETO sterilization process is controlled through temperature, concentration, time, humidity, pre-vacuum leak alert, and atmospheric pressure safe-release logic to support sterility assurance.

PRE-TRIAL REQUEST CHECKLIST
Before samples or a filling-line trial, confirm the SKU, RTU packaging configuration and document scope below. Public references are shown separately; batch-specific and controlled records are released only for the agreed project stage.
Public reference set: 2026-09-22 | SOP/ZG 241, 242, 243 and 248: A/1, effective 2026-07-02
Confirm the vial SKU, nominal size (for example 2R, 6R or 10R), glass type, neck/finish, drawing revision and required dimensional tolerances.
SKU-specific dimensional drawing, CAD/drawing revision and approved specification boundary. Do not use a Nest drawing as evidence for a Tray SKU.
Select Nest & Tub or Tray, confirm nest/tub/tray interface, bag configuration, carton and pallet requirements, and the intended Grade A/B transfer route.
Packaging configuration record plus the applicable controlled quality standards for the tub, nest, tray and breathing bags.
Confirm sample quantity, destination, Incoterms, importer or consignee requirements, requested supply status and whether the trial is development, qualification or commercial preparation.
A project-specific supply and sample plan. Country or project statements are limited to the confirmed scope and date on the request.
Confirm whether the requested RTU SKU is supplied pre-sterilized, the applicable sterilization summary, storage and transport conditions, shelf-life or retest basis, and release status.
Status-matched sterilization, storage, transport and release documents. These are not substituted by a generic product page statement.
Identify the batch or sample lot and the tests required for release, including appearance, dimensions, particulate, sterility, endotoxin and other agreed attributes.
A batch-linked CoA or agreed release package. A generic sample CoA is not a substitute for the formal batch release record.
