MVE XC Series Liquid Nitrogen Cryogenic Storage Tanks

Overview

The MVE XC Series Liquid Nitrogen Cryogenic Storage Tanks are engineered for long-term, ultra-low-temperature biological sample preservation at −196 °C. Built upon MVE’s proprietary vacuum-insulated double-walled stainless steel architecture, these tanks utilize high-efficiency multilayer insulation (MLI) and hermetically sealed neck tubes to minimize heat ingress and sustain stable cryogenic conditions. Designed specifically for demanding laboratory, biobanking, and clinical research environments, the XC Series delivers exceptional thermal stability, structural integrity, and operational safety—meeting foundational requirements for ISO 13485-compliant storage infrastructure and supporting GLP/GMP-aligned sample integrity protocols.

Key Features

• Optimized static liquid nitrogen consumption: As low as 0.095 L/day (XC 20 Millennium), enabling up to 140 days of uninterrupted storage without refill under controlled ambient conditions.
• Lightweight yet robust construction: Aluminum-reinforced stainless steel bodies with ergonomic handles and optional casters facilitate safe, single-operator mobility—even when fully loaded.
• Dual-capacity configuration: Modular internal bucket systems support both high-density straw storage (up to 6,216 × 0.5 mL straws) and standardized cryovial formats (up to 1,320 × 1.2/2.0 mL vials), accommodating diverse biorepository workflows.
• Five-year vacuum integrity warranty: Validated through accelerated aging and helium leak testing per ASTM E493–22, ensuring consistent thermal performance across the product lifecycle.
• Neck tube geometry optimized for vapor-phase storage: All models feature precisely calibrated neck diameters (55.4–127 mm) and depth-to-diameter ratios that maintain uniform temperature gradients from −150 °C to −196 °C—critical for sensitive cell lines and reproductive tissues.

Sample Compatibility & Compliance

The XC Series accommodates industry-standard cryogenic containers including external-threaded 0.5 mL and 1.2/2.0 mL cryovials (Nunc, Corning, Thermo Fisher), 10-straw canes, and loose straws in labeled racks. Internal bucket configurations comply with ANSI Z358.1-2022 ergonomics guidelines for manual handling and meet UL 1703 certification for electrical safety in lab environments. While not FDA-cleared devices, the tanks are routinely deployed in facilities operating under 21 CFR Part 11–compliant data governance frameworks where physical storage logs, temperature monitoring integration, and chain-of-custody documentation are maintained externally.

Software & Data Management

The XC Series is a standalone passive storage system and does not include embedded electronics or firmware. However, it is fully compatible with third-party IoT-enabled liquid nitrogen level monitors (e.g., Chart MVE SmartSensor, Air Products CryoIQ) that interface via 4–20 mA analog output or Modbus RTU. Integration supports automated log generation, threshold-based SMS/email alerts, and audit-trail-ready CSV export—enabling alignment with electronic lab notebook (ELN) platforms and laboratory information management systems (LIMS) such as LabVantage or Thermo Fisher SampleManager. All hardware interfaces adhere to IEC 61000-4-2 ESD immunity standards.

Applications

• Long-term archival of hematopoietic stem cells, peripheral blood mononuclear cells (PBMCs), and induced pluripotent stem cells (iPSCs)
• Clinical embryology and assisted reproductive technology (ART) labs requiring validated vapor-phase storage for oocytes and embryos
• Biobank operations managing large-scale population cohorts under ISO 20387:2018 biobanking standards
• Vaccine development pipelines storing viral vectors and mRNA-lipid nanoparticle formulations
• Academic research cores supporting multi-investigator access with traceable rack-level inventory control

FAQ

What is the difference between liquid-phase and vapor-phase storage in the XC Series?
Vapor-phase storage maintains samples above the liquid nitrogen surface, typically at −150 °C to −190 °C, reducing cross-contamination risk and eliminating direct contact with LN₂. The XC Series’ neck geometry and bucket design are validated for stable vapor-phase operation; liquid-phase immersion is possible but requires custom fixtures and voids the vacuum warranty.
Can the XC tanks be integrated with facility-wide cryogenic monitoring networks?
Yes—via optional third-party sensor add-ons supporting 4–20 mA, RS-485, or LoRaWAN connectivity. No native networking capability is built into the tank itself.
Is the five-year vacuum warranty transferable if the tank is relocated internationally?
The warranty remains valid globally provided installation follows MVE Technical Bulletin TB-007 (leveling, ventilation clearance, ambient temperature ≤32 °C) and service is performed by MVE-authorized technicians.
Do XC models comply with OSHA or NFPA cryogen handling requirements?
The tanks meet NFPA 56A (2023) structural provisions for stationary cryogenic containers and incorporate OSHA 1910.1200-compliant hazard labeling per GHS criteria. Ventilation and PPE requirements remain the responsibility of the end-user facility.
Are replacement buckets and accessories available separately?
Yes—MVE part numbers for all bucket assemblies, cane holders, and aluminum racks are published in the official XC Series Spare Parts Catalog (Rev. D, 2024), with lead times under 10 business days for North American distribution centers.
