Nest and Tub Open Sterile Vials - Sized Right for Compounding USP <797> Small-Batch CSPs

If you're compounding sterile preparations in smaller runs, ordering vials by the case doesn't make sense — you end up paying for volume you don't need, storing more than you'll use before your next batch, and tracking documentation for units that never leave the shelf. Small Nest in Tub ISO vial packs are sized specifically for that reality: 100 vials (or less), matched to the ≤250 final-yield-unit threshold that triggers USP <797> sterility testing requirements for Compounded Sterile Preparations.

What size are these vials, and why 2R? An ISO 2R vial is 16mm x 35mm, the standard 2R format used across pharmacy compounding and lab dispensing for small-volume fills. The amber (UV-protective) borosilicate glass shields light-sensitive formulations without needing secondary packaging. 

What volume of CSP can an ISO 2R Vial Hold? An ISO 2R vial is frequently used for either 2ml or 3ml CSP fill volumes.

What glass standard do these meet? USP Type I borosilicate glass — the pharmacopeia standard for chemical durability and resistance to leaching, appropriate for parenteral and other sterile-preparation use.

Why does the tray count matter for compliance? USP <797> requires sterility testing for CSP batches, and the testing burden scales with batch size. A 100-count tray keeps you comfortably under the 250-unit final-yield threshold many facilities use as a practical ceiling for a single sterility-tested batch — so you're not opening a 500- or 1,000-count case just to pull 80 vials for one compounding run.

How are the vials protected in shipping? Vials sit in individual cavities inside a nested protection sleeve tray (a tray-in-tub style format), so no vial touches another in transit. That eliminates the chipped rims and scuffing you get from vials packed loose or stacked in bulk cartons.

What documentation ships with the vials? Every lot includes third-party sterility and endotoxin testing reports, generated by an independent U.S. laboratory that's FDA-registered and holds GMP, GLP, and GTP certification with ISO/IEC 17025 accreditation. That's the paperwork most compounding pharmacies need on file for inspection-readiness, included by default rather than something you have to request separately.

Are the manufacturers FDA-registered? Yes — the various manufacturers we source from all maintain an active Drug Master File (DMF) with the FDA, which supports regulatory traceability if your facility needs to document vial sourcing as part of a compounding audit.
