Frequently Asked Questions What is the difference between internal and external thread CryoCLEAR vials? External-thread caps seal outside the vial body, easing decontamination and reducing thread contamination. Internal-thread caps recess within the rim for a lower profile. Both use the same co-molded TPE seal; choice depends on your rack format and workflow preference. Are CryoCLEAR vials rated for liquid nitrogen storage? Yes. The polypropylene construction and TPE-sealed screwcap are designed for cryogenic temperatures. For long-term liquid-nitrogen storage, vapor-phase storage is recommended to minimize the risk of liquid ingress and pressure buildup. Are these vials supplied sterile? All listed CryoCLEAR vials are sterile and non-pyrogenic, packaged ready for cell culture and clinical sample handling without additional autoclaving before first use. What does the 50/bag pack contain versus the color-cap case items? Standard SKUs (e.g., 3010-50 through 3015-50) are sold in bags of 50 vials. The color-cap configurations (3012B, 3012G, 3012R, 3012V, 3012W, 3012Y) are supplied as larger cases, which is reflected in their per-pack price. { "@context": "https://schema.org", "@type": "Product", "name": "Globe Scientific CryoCLEAR Cryogenic Vials, 1.0–5.0 mL Sterile, Internal & External Thread", "brand": {"@type": "Brand", "name": "Globe Scientific"}, "description": "Sterile clear polypropylene cryogenic vials, 1.0–5.0 mL, with attached or assembled screwcaps featuring co-molded TPE seals.
