Union Carbide 35VHC 35L Cryogenic Storage Tank for Biological Samples

The Union Carbide 35VHC Cryogenic Storage Tank is engineered for long-term preservation of biological samples, including cell cultures and tissue specimens, critical for biotechnology and molecular diagnostics workflows. This high-capacity container holds 35 liters of liquid nitrogen, maintaining temperatures as low as -196°C (-320°F) at the liquid surface, and approximately -184°C (-299°F) under the sealed necktube core, ensuring optimal sample viability for cryogenic biobanking.

Key technical features include:

• Capacity: Supports 6 stainless steel hanging racks with numbered grooves (5 racks included), each rack accommodates 10 × 100-cell boxes (boxes not included), providing scalable storage solutions for bioprocessing and synthetic biology sample banks.
• Construction: Rugged high-strength aluminum body with ribbed design and magniformed necktube enhances durability and vacuum integrity, suitable for demanding biomedical engineering environments.
• Vacuum Insulation: Superior multi-layer vacuum and super insulation technology delivers a static holding time of up to 130 days, reducing liquid nitrogen consumption to an evaporation rate of 0.27 liters/day—essential for continuous biomanufacturing and gene editing research storage.
• Mobility and Security: Equipped with included roller bases for easy transport within clinical diagnostics and research labs; optional low-level liquid nitrogen alarm available to protect critical molecular biology samples (alarm not included).
• Dimensions & Weight: Neck diameter of 4.7", overall diameter 18.8", empty weight 37.9 lbs, and full weight 100.2 lbs, compatible with standard cryogenic lab infrastructure.

This cryogenic storage solution is widely adopted in biotechnology research, including molecular cloning workflows, live-cell preservation, and biopharmaceutical production pipelines, offering reliable, secure storage for sensitive biological materials. Its robust design, prolonged holding time, and adaptability make it a critical instrument in advanced cryogenic sample preservation for clinical and research applications.
