Puretest 0.5 mL cryogenic vials are organized as one capacity-based product family for compact low-volume aliquots and space-efficient freezer organization. Instead of splitting minor structural variations into duplicate product links, this page presents the available closure, cap, body-color and base options together so laboratories and distributors can compare configurations efficiently.

Product Highlights

• One capacity, multiple configurations: request the required structure from a single 0.5 mL product page.
• Laboratory-grade polypropylene: clear formats support sample visibility; selected amber formats provide light protection.
• Identification-ready: graduations, writing areas and optional cap colors support organized freezer inventories.
• Qualification support: dimensional drawings, samples and available batch documentation can be confirmed before ordering.
• OEM-ready supply: cap color, label, inner packaging and carton presentation can be discussed for qualified projects.

Available 0.5 mL Configurations

Technical Specifications

Vial Structure and Functional Design

• Ribbed screw caps support controlled opening and closing while wearing laboratory gloves.
• Clear walls allow visual inspection; amber bodies are available where light protection is required.
• Base geometry affects standing stability, residual sample recovery and rack compatibility.
• Graduations are reference markings rather than calibrated volumetric measurements.
• Request the dimensional drawing before qualifying an existing cryobox, rack, cane or automated storage system.

Applications

• Low-volume cell and microorganism aliquots
• Reference reagents and retained samples
• Research biobanks and freezer inventories

How to Specify the Correct Vial

1. Confirm nominal capacity and required working volume.
2. Select body color, base geometry, cap height and closure/seal construction.
3. State sterility, cleanliness, documentation and packaging requirements.
4. Compare the drawing with the intended rack, freezer box and handling workflow.

Storage and Safety

Use vapor-phase liquid-nitrogen storage unless the selected vial and closure combination has been specifically validated for liquid immersion. Leave adequate headspace for freezing expansion, wear suitable personal protective equipment and follow the laboratory’s validated filling, freezing, retrieval and disposal procedures.

Frequently Asked Questions

Are all 0.5 mL variants separate products?

No. This consolidated page covers the 0.5 mL family. State the exact cap, base, color and seal configuration in the sample or quotation request.

Can Puretest provide samples and dimensional drawings?

Yes. Sample availability and drawing revision should be confirmed against the exact configuration before qualification.

Can I request private-label packaging?

Yes. Labels, cap colors, inner packaging and carton presentation can be discussed for qualified OEM and distributor projects.
