DWK 225288 WHEATON LAB FILE Sample Vials, Clear, 20mL Standard Vials With Caps Attached, 14B Rubber

The WHEATON® LAB FILE® 225288 is a 20 mL clear borosilicate glass sample vial supplied with an attached 24-400 black phenolic screw cap and 14B rubber liner. The manufacturer identifies this liner configuration primarily for compatible aqueous samples.

Each standard-height vial measures 28 × 60 mm. LAB FILE® partitioned trays help organize the supplied containers and stored samples.

Glass composition, closure material, liner selection, sample chemistry, preparation, and storage conditions all influence the suitability of the complete container system.

The manufacturer-listed dimensions are for identifying this vial configuration. No separate calibrated volume tolerance, brimful capacity, pressure rating, or maximum working-fill volume is established in the reviewed records.

WHEATON 225288 is converted from clear Type I borosilicate glass tubing. DWK's catalog-specific material field identifies the construction as Clear Type 1A Borosilicate.

Borosilicate glass is used extensively in laboratory containers because of its chemical durability and resistance to water-based chemical attack. Exact compatibility still depends on the formulation, processing conditions, and closure components.

General borosilicate glass information is available in the manufacturer's Glass Types and Properties technical reference listed below.

The included black phenolic screw cap uses a 24-400 finish and a solid-top construction. Its sealing interface incorporates a 14B rubber liner.

The nominal 24-400 finish identifies the closure thread configuration, not a 24 mm clear internal mouth opening. Matching closure components should be selected using the specified finish and the intended liner material.

A solid-top cap should not be treated as an open-top septum cap. The manufacturer's description does not establish a needle-puncture procedure, repeated septum access, or autosampler compatibility for this supplied cap.

DWK's technical closure-liner guide identifies 14B rubber as a sulfur-cured styrene-butadiene rubber (SBR) formulation. It is not natural rubber. This identification should not be confused with a product-specific latex-free or allergen-control certification.

The manufacturer describes this liner as having useful resilience and resistance to moisture-vapor transmission, with suitability for many moderate chemical exposures. For the LAB FILE® vial family, DWK identifies plain 14B rubber as the liner option intended for aqueous samples.

The same technical guidance identifies poor compatibility with oils, strong acids, and hydrocarbons. Consequently, the plain 14B rubber liner should not be presented as a universal solvent-resistant closure.

The manufacturer's general liner guide discusses rubber composition and regulatory material characteristics. Those statements do not by themselves certify this finished vial assembly for any specific pharmaceutical, food-contact, or sterile application.

A PTFE-faced rubber liner introduces a different sample-contact surface. That may be preferable for certain formulations, but no liner material eliminates the need for application compatibility testing.

WHEATON supplies catalog 225288 with the specified screw caps attached to the vials. This presentation is intended to help maintain cleanliness during supply and handling.

LAB FILE® partitioned trays offer an organized format for empty vials or stored samples. This packaging arrangement can assist laboratories with inventory and sample identification.

Caps attached does not mean permanently tethered caps, and partitioned trays do not establish a sterile barrier. The reviewed records also do not establish a separate numeric inner-pack quantity within the 72-count case.

DWK identifies the LAB FILE® vials and caps as autoclavable. The closure-liner technical guide also identifies 14B rubber as autoclavable material.

That does not establish a universal steam-autoclave cycle for every filled, capped, or tightly sealed configuration. Processing requirements should be established for the actual container, closure, contents, and laboratory procedure.

Where appropriate, an approved preparation process should include controls for cleaning, loading, closure condition, heating, cooling, and inspection of the processed assembly.

Type I borosilicate glass is valued for its chemical durability, but sample compatibility must be assessed across the glass, phenolic closure, and 14B rubber liner.

The appropriate selection depends on the chemical composition, concentration, storage temperature, contact time, and required analytical method performance.

• Glass compatibility: Evaluate the specific formulation against the borosilicate container.
• Closure compatibility: Confirm the 14B rubber liner is suitable for the contents.
• Sample stability: Establish the required storage duration and conditions.
• Potential contamination: Evaluate extractables or sample interactions where analytical limits require it.
• Evaporation and retention: Confirm the closure assembly meets the method's required containment performance.
• Light sensitivity: Use an approved amber configuration if the contents require light protection.

No numerical extractables limit, validated chemical-specific shelf life, or quantified leak-rate specification is established for SKU 225288 in the reviewed records.

Related products should not be substituted without reviewing glass color, liner material, closure configuration, dimensions, case quantities, and analytical requirements.

Important difference: The uncapped 224831 version has manufacturer-listed dimensions of 28 × 57 mm and a 200-vial case, whereas 225288 is 28 × 60 mm with attached caps and 72 vials per case.

DWK's catalog-specific specifications list the following storage accessory references for 225288:

These are manufacturer-listed compatibility references. The accessories are not identified as included in the 225288 case. Confirm the intended storage configuration and availability through SOSCleanroom.

• Confirm product identity: Check catalog 225288, clear 20 mL glass, and 72 vials per case.
• Verify vial geometry: Confirm the required 28 mm diameter, 60 mm height, and 24-400 finish.
• Inspect glass surfaces: Check the vial body, mouth, threads, and base for cracks, chips, or visible contamination.
• Verify supplied closures: Confirm black phenolic caps and plain 14B rubber liners are present.
• Inspect liner condition: Check for deformation, displacement, contamination, or damage.
• Check tray packaging: Inspect the LAB FILE® partitions and investigate broken containers.
• Review preparation status: Follow the facility's requirements for cleaning and any necessary sterilization.
• Maintain records: Use the laboratory's product-acceptance and sample-identification procedures.

The manufacturer item-setup record lists room-temperature shipping and storage for the supplied empty product. This does not establish storage requirements for every filled vial.

Glass should be protected from impact, and the rubber-lined closure should be evaluated for the actual sample, storage duration, and environmental conditions.

The reviewed product record does not assign an ISO cleanroom classification, quantified particle-release limit, supplied sterile status, or universal filled-sample shelf life. Controlled-environment applications require facility-specific qualification.

The following technical references explain glass classifications, chemical durability, rubber liner materials, and closure selection. They are technical-information resources, not purchasing pages.

Documentation note: General material properties are not lot-specific test results or finished-container performance certifications. Contact SOSCleanroom for additional documentation when required.
