WHEATON 986701: Exact-SKU Technical Overview
WHEATON® 986701 is a 20 mL white high-density polyethylene (HDPE) liquid scintillation vial supplied with an attached white polypropylene 22-400 screw cap and metal foil/pulp liner. The manufacturer specifies a 27 mm outside diameter, 57 mm height without cap, and 61 mm overall capped height.
DWK identifies the exact product as non-sterile, with no marking spot, and supplies it in cases of 500 vial-and-cap units. The current 986701 product record does not publish an autoclavability field.
The primary selection difference from WHEATON 986700 is the metal foil/pulp liner rather than foamed polyethylene. The two products otherwise share the same named HDPE vial material, 22-400 polypropylene cap, published dimensions, and attached-cap presentation.
DWK's general Closure Liner Guide describes metal foil/pulp as aluminum foil bonded to pulp board. It reports good barrier characteristics and general resistance to hydrocarbons, oils, ketones, and alcohols, but identifies acids and alkalis as unsuitable for this liner type.
The complete 986701 container includes three material components: white HDPE vial, white polypropylene cap, and metal foil/pulp liner. Compatibility of the liner alone does not establish compatibility of the complete assembly with a particular liquid scintillation cocktail or laboratory sample.
Operations takeaway: Order 986701 for a 20 mL white HDPE vial, 27 x 57 mm without cap / 27 x 61 mm capped, attached white PP 22-400 cap, metal foil/pulp liner, 500 per case. The product is non-sterile. The exact SKU has no published autoclave field, but DWK generally identifies HDPE as not autoclavable.

Metal Foil/Pulp Liner: Construction and Technical Properties
DWK identifies the liner supplied with WHEATON 986701 as metal foil/pulp. Its general Closure Liner Guide describes pulp/metal foil as aluminum foil bonded to pulp board.
The aluminum foil layer and pulp-board backing form a composite liner distinct from polyethylene foam, polyethylene discs, polyethylene cones, and metal foil/cork. These liner materials have different manufacturer descriptions and should not be substituted solely because they are used with 22-400 screw caps.
DWK describes foil/pulp as having good barrier properties and general resistance to hydrocarbons, oils, ketones, and alcohols. These characteristics may be relevant to methods involving certain compatible organic solvent formulations.
However, the same technical guide specifically notes that this liner type is not good for acids or alkalis. Some liquid scintillation samples contain acidic or alkaline reagents, buffers, or mixed chemical systems, making application-specific compatibility review necessary.

The properties above are general material descriptions. They are not numerical chemical-exposure test results for the assembled 986701 vial. Real performance can vary according to the solvent mixture, concentration, temperature, exposure time, cap condition, and closure handling.
Important liner limitation: Good resistance of foil/pulp to certain organic chemicals does not establish universal compatibility of the HDPE vial, polypropylene cap, and foil/pulp liner. Review the full chemical formulation and test the complete container-closure system when required.
986701 vs. 986700: Foil/Pulp Compared with Foamed Polyethylene
WHEATON 986701 and 986700 share a white 20 mL HDPE vial body and white polypropylene 22-400 attached cap. Their published dimensions are the same. The difference is the manufacturer-specified liner construction.

Selection principle: Foil/pulp and foamed PE have different chemical-resistance profiles. Neither should be represented as universally superior. The correct selection depends on the complete sample formulation, analytical requirements, and tested closure performance.
Foil/Pulp vs. Foil/Cork: 986701 Compared with 986702
WHEATON 986701 and 986702 both use a white HDPE 20 mL vial with a 22-400 threaded closure. However, 986701 includes a white polypropylene cap with metal foil/pulp liner, while 986702 uses a white urea cap with metal foil/cork liner.
The two closures differ in both cap-body material and liner backing material. DWK's Closure Liner Guide documents chemical-resistance characteristics for pulp/metal foil, but the same values should not be transferred to metal foil/cork without product-specific evidence.
- 986701: White PP cap with metal foil/pulp liner.
- 986702: White urea cap with metal foil/cork liner.
- Shared vial material: White HDPE.
- Shared thread: 22-400.
- Shared nominal dimensions: 27 x 61 mm capped.
- Important limitation: Different cap and liner materials require independent compatibility evaluation.
High-Density Polyethylene: Material Properties and Limitations
HDPE is a polyethylene polymer used in a variety of laboratory containers. WHEATON 986701 uses a white HDPE vial body, making it different from the transparent glass and PET configurations offered within the WHEATON scintillation-vial family.
DWK's Typical Properties of Plastics guide lists general physical, thermal, and sterilization properties for HDPE and other polymer materials. These reference values can guide preliminary material selection but do not establish a qualified operating-temperature range, optical response, chemical compatibility, or sterilization cycle for the exact 986701 vial.
General HDPE material characteristics must also be considered alongside the other parts of the assembly. The white polypropylene cap may have different chemical and thermal properties, and the foil/pulp liner has a distinct chemical-resistance profile.

Material qualification warning: Do not use an HDPE-only chemical-resistance chart to approve the complete product. The polypropylene cap and foil/pulp liner may have different limitations from the vial body.
HDPE vs. PET vs. Borosilicate Glass Scintillation Vials
WHEATON offers 20 mL liquid scintillation vials manufactured from HDPE, PET, and borosilicate glass. Although these configurations can share a 22-400 thread and similar overall height, their material properties and dimensions are not identical.

Even with the same named cap and liner, HDPE, PET, and glass can differ in chemical interaction, analytical background, optical response, thermal behavior, and instrument-fit characteristics. Method qualification must address the actual vial material.
Chemical Compatibility: Evaluate HDPE, PP, and Foil/Pulp Together
During laboratory use, a liquid scintillation vial may be exposed to sample liquids, scintillation cocktails, solvent vapors, condensation, and cleaning agents. For WHEATON 986701, the relevant materials are HDPE, polypropylene, and metal foil/pulp.
The manufacturer's general foil/pulp guidance identifies good resistance to several classes of organic chemicals, but compatibility of the complete assembly is not established by the liner alone. The HDPE vial and polypropylene cap must also withstand the actual formulation and conditions of use.
| Chemical exposure |
Qualification consideration |
| Hydrocarbon-containing cocktails |
Foil/pulp has good general resistance; HDPE, PP, complete mixture, and seal must still be evaluated |
| Alcohol-containing solutions |
General foil/pulp resistance described; verify the particular alcohol and conditions |
| Ketone-containing mixtures |

This table provides a chemical compatibility review framework, not a certified approved-chemical list for the exact 986701 assembly. Verify concentration, time, temperature, and the specific solvent composition.
Important: The foil/pulp liner's general hydrocarbon resistance does not establish that the HDPE vial can safely contain every hydrocarbon scintillation cocktail. Review the complete assembly before use.
Liquid Scintillation Counting: Analytical and Optical Considerations
Liquid scintillation counting (LSC) is a laboratory technique used to quantify suitable radioactive samples. A sample is combined with an appropriate scintillation cocktail, and energy deposited in the cocktail produces light that a counting instrument can detect.
The vial is one part of the analytical system. Vial material and color, sample chemistry, cocktail formulation, counting geometry, background contributions, and instrument settings can all influence the measured result.
DWK's broader liquid scintillation-vial family description mentions consistent low background counts and high UV transmission. However, the family contains multiple materials and colors, including clear glass, PET, and white HDPE.
For WHEATON 986701, no exact numerical background count, UV transmission spectrum, isotope-specific counting efficiency, or instrument-independent detection limit was established in the reviewed manufacturer specifications.
- Background controls: Use method-defined blanks and background measurements.
- Instrument material selection: Confirm the instrument accepts white HDPE vials.
- Optical response: Do not assume the same UV transmission as clear glass.
- Counting efficiency: Establish through the actual instrument and analytical method.
- Quench correction: Follow the instrument and method's validated procedures.
- Working volume: Use the approved sample-to-cocktail ratio rather than nominal vial capacity.
- Analytical controls: Use standards, blanks, and appropriate sample recovery checks.
Analytical performance boundary: White HDPE must not be described as having the same verified UV transmission or counting background as borosilicate glass. WHEATON 986701 is a laboratory sample container, not a calibrated radiation-measurement instrument.
22-400 Screw Thread, Cap Fit, and Instrument Clearance
WHEATON 986701 uses a 22-400 threaded finish. DWK's Closure Liner Guide explains that the closure and container thread finishes must match. A 24-400 screw cap should not be assumed to fit a 22-400 vial.
The manufacturer specifies a 27 mm vial diameter, 57 mm height without cap, and 61 mm total assembled height. These values support preliminary instrument and storage-rack selection.

WHEATON's related clear-glass 20 mL vials have a published 28 mm diameter, rather than the 27 mm listed for this HDPE version. Do not assume identical equipment fit based on capacity or capped height alone.
Sterility and Autoclavability: Exact Product vs. General Material Guidance
DWK explicitly specifies WHEATON 986701 as non-sterile. The exact product record does not publish an autoclavability field.
DWK's separate Typical Properties of Plastics guide identifies HDPE as not autoclavable. Because 986701 uses an HDPE vial body, the assembled product should not be autoclaved without written, product-specific manufacturer approval.
The polypropylene cap's general material properties do not qualify the complete HDPE/PP/foil-pulp system for steam processing. Similarly, generic plastics data describing possible gas or radiation sterilization does not establish a validated process for the exact 986701 assembly.
| Question |
Manufacturer evidence and recommendation |
| Is 986701 supplied sterile? |
No; exact-SKU designation is non-sterile |
| Does the exact SKU publish an autoclavability rating? |
No field in the reviewed product record |
| Is HDPE generally autoclavable? |
DWK general plastics guide: No |
| Does a polypropylene cap establish autoclavability? |
No; complete assembly must be qualified |
| Is a validated sterilization cycle supplied? |
No exact-SKU process established |
Processing warning: Do not autoclave WHEATON 986701 based on the polypropylene cap's general heat characteristics. No validated 121°C steam cycle, sterile processing claim, or other SKU-specific sterilization procedure has been established.
Closure Handling, Seal Integrity, and Solvent Vapor Control
The attached white PP screw cap and foil/pulp liner form the manufacturer-defined 986701 closure system. However, the presence of a metal foil liner and correctly matched screw thread does not establish a certified leakproof, vapor-tight, hermetic, pressure-resistant, or hazardous-material transport seal.
Actual closure performance depends on the vial neck, cap threads, liner condition, chemical exposure, fill level, temperature, and method of cap application.
- Inspect the vial rim and cap threads for defects or contamination.
- Inspect the metal foil/pulp liner for damage or displacement.
- Use the specified 22-400 closure finish.
- Follow the laboratory's approved cap-application procedure.
- Do not assign an unsupported numerical tightening torque.
- Evaluate evaporation and vapor exposure for volatile mixtures.
- Use suitable secondary containment where required.
- Follow applicable chemical and radiological safety procedures.

Liquid scintillation vials may contain chemical solvents or radioactive residues. The laboratory should determine whether reuse is permitted by its analytical method and whether contamination or sample carryover creates unacceptable risks.
- Confirm that the analytical method permits reuse.
- Assess hazardous or radioactive contamination before handling.
- Use cleaning reagents compatible with HDPE, PP, and foil/pulp.
- Avoid abrasive equipment or damage to threads and liner surfaces.
- Do not use unapproved autoclaving or excessive heat.
- Inspect the vial and closure before any permitted reuse.
- Use required blank and carryover acceptance checks.
- Follow approved storage, labeling, and waste procedures.
Controlled Laboratory and Cleanroom Qualification
WHEATON 986701 may be evaluated for appropriate analytical laboratory applications, but the exact manufacturer specification identifies it as non-sterile. The reviewed record does not establish an ISO 14644 product cleanliness class, validated sterile barrier, endotoxin limit, DNase/RNase-free status, or certified particle-release specification.
For controlled-environment use, follow facility procedures for material introduction, labeling, contamination control, and product qualification. A laboratory plastic material designation does not automatically establish suitability for aseptic processing, sterile compounding, or pharmaceutical manufacturing.
Qualification boundary: WHEATON 986701 should not be represented as sterile, ISO-classified, pharmaceutical-grade, or cleanroom-ready without specific supporting manufacturer documentation.
