Amber Sample Storage Vial

What is the Amber Sample Storage Vial?

An amber sample storage vial protects light-sensitive compounds from ultraviolet and short-wavelength light. It is used for standards, drugs and dyes that degrade in clear glass. It blocks ultraviolet and short-wavelength light.

Overview

The vial is made from amber borosilicate or soda-lime glass, which absorbs ultraviolet and much of the short-wavelength visible light that would otherwise degrade compounds such as vitamins, dyes, some antibiotics and many natural products. Sizes range from 1.5 mL to 40 mL, with screw caps and PTFE-faced septa or lined closures, and inserts for small volumes. Amber glass does not protect against all light, so prolonged exposure to strong sunlight should still be avoided, and dark storage is preferred for very sensitive standards. The vial is used for standard solutions, reference materials, pharmaceutical samples and photodegradable analytes, and the closure must be chemically compatible with the solvent and help prevent evaporation during storage.

How does it work?

A sample vial holds a small volume of liquid or headspace gas and is pierced by the autosampler needle through a septum. The vial material must not leach into or adsorb from the sample, so glass, usually borosilicate or Type I, is preferred for organic solvents and trace analysis, and polypropylene is used for aqueous and inorganic samples. The septum is the critical part: silicone, PTFE-faced silicone, butyl or natural rubber are chosen for chemical compatibility, resealing ability and pierce count. The cap and crimp or screw thread must hold the septum flat so no leak or evaporation occurs, because even small losses change concentrations over a long run. Surface treatment and low-adsorption glass help with polar or basic analytes, while amber glass protects light-sensitive compounds. Dimensions follow recognised standards so vials fit autosampler trays and magazines reliably.

What are the key features?

• Amber borosilicate or soda-lime glass
• Blocks UV and short-wavelength light
• Sizes 1.5–40 mL
• Screw cap with PTFE-faced septum
• Insert option for small volumes
• For photodegradable analytes

What are the technical specifications?

A typical amber sample storage vial configuration offers material of Amber borosilicate or soda-lime, volume of 1.5–40 mL, light protection of UV and short-wavelength, closure of Screw cap, septum or liner of PTFE-faced and insert of Optional. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Amber Sample Storage Vial is used in standard solution storage, pharmaceutical sample storage, vitamin and dye analysis and natural product research. Across the wider Vials class, laboratories also deploy it for HPLC and UHPLC autosampling, gas chromatography injection and headspace analysis.

Which standards and certifications apply?

Relevant standards and methods include USP <660> (glass containers), EP 3.2.1 (glass containers for pharmaceutical use), ISO 8362 (injection containers and accessories), USP <661> (plastic components and systems), USP <1664> (assessment of drug product leachables) and GHS labelling requirements. Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Fill vials to the recommended level, usually 50–75 % of the volume, so there is enough headspace for the autosampler and no sample is lost to the septum, and never overfill, because pressure can force liquid out or distort the septum. Use the correct crimp tool and torque, since a loose or over-tightened cap leaks or deforms the septum. Discard vials with damaged septa or distorted caps, and avoid reusing septa, because piercings do not reseal perfectly. Store standards in vials with minimal headspace, seal them well and use amber glass for light-sensitive compounds. Check that vials meet dimensional standards so they do not jam the autosampler, and use only the septa validated for the method, because a different septum can introduce new peaks.

How do I select the right Amber Sample Storage Vial?

Choose amber vials for any analyte that degrades in light, and still store very sensitive standards in the dark. Confirm volume and closure. RFQ: volume, solvent, closure, septum and storage conditions. Provide volume, solvent and storage conditions.

How does it compare with other Vials variants?

Choose the vial to fit the autosampler first, since tray and magazine dimensions are fixed, then choose the closure for the sample and the mobile phase. For reversed-phase HPLC with aqueous and organic mobile phases, a screw-top vial with a PTFE-faced silicone septum is common and convenient. For headspace analysis, use a vial rated for the pressure and temperature of the headspace sampler, with a septum that reseals after each of the several piercings. For GC, crimp-top vials with a low-bleed septum reduce background peaks. Choose amber glass for light-sensitive compounds, and low-adsorption or deactivated glass for basic and polar analytes that bind to active silanol sites. Confirm septum and cap compatibility, volume and any certification for trace metals or leachables, and check that inserts fit the vials and the autosampler needle.
