2ml/5ml Side-Coded Cryogenic Vials

Our 2 mL and 5 mL Side‑Coded Cryogenic Vials are constructed from medical‑grade polypropylene and withstand repeated autoclaving and freeze‑thaw cycles. Featuring self‑standing bases and color‑coded caps (7 hues), each vial bears a laser‑etched 1D barcode and human‑readable ID on its side for rapid scanning. The 2 mL format comes in both internal‑ and external‑thread versions-the latter cap design omits an O‑ring to minimize contamination risk. Graduated markings in black and a white writing area simplify sample labeling. Compatible with 1", 2", and 3.75" rack formats, these vials are gamma‑sterilized, free of RNase/DNase/endotoxin/foreign DNA, non‑pyrogenic, and operate reliably from ‑196 °C to 121 °C in vapor‑phase liquid nitrogen storage.

FAQ

Q1: Can these vials be autoclaved repeatedly?
A1: Yes-made of PP, they tolerate standard autoclaving cycles without degradation.

Q2: What makes side‑coded vials advantageous?
A2: The 1D barcode and clear numbering on the vial's side enable fast, error‑free scanning without removing caps.

Q3: Why choose external‑thread 2 mL vials without an O‑ring?
A3: Removing the O‑ring reduces crevices where contaminants can lodge, simplifying cleaning and reducing contamination risk.

Q4: Which rack sizes are supported?
A4: These vials fit all standard cryogenic racks: 1″, 2″, and 3.75″ formats.

Q5: Are they safe for ultra‑low temperatures?
A5: Absolutely-they function from liquid nitrogen vapor (‑196 °C) up to autoclave temperatures (121 °C).
