Puretest 1.8 mL cryogenic vials are organized as one capacity-based product family for routine biobanking and laboratory sample storage with flexible closure and base geometry. 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.
| Configuration | Design purpose |
|---|---|
| Hex-base vial | Faceted self-standing base supports compatible anti-rotation racks. |
| Hex flat-bottom vial | Combines a stable flat base with faceted handling geometry. |
| Internal-thread option | Plug-style closure with seal construction selected by specification. |
| External-thread option | Over-cap closure engages the outside of the vial neck. |
| Cap color options | Visual coding can distinguish sample groups or workflows. |
| Nominal capacity | 1.8 mL |
|---|---|
| Vial material | Laboratory-grade polypropylene; clear or amber option where listed |
| Closure material | Polypropylene; seal construction varies by selected configuration |
| Thread / closure | Internal thread or external thread |
| Base options | Hex, hex flat-bottom or other self-standing base by configuration |
| Identification | Graduations, writing area and optional color-coded cap or insert |
| Sterility and cleanliness | Sterile and controlled-cleanliness configurations available; confirm the required claim and supporting document before order |
| Packaging | Bulk, inner-bag and private-label options subject to selected item and order quantity |
| Storage guidance | Ultra-low-temperature and vapor-phase liquid-nitrogen workflows; do not immerse unless the exact vial/closure configuration is validated for liquid-phase use |
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.
