TAIYO NIPPON SANSO CryoHandy Wide MR-LN-6000 Portable Vapor-phase Liquid Nitrogen Transport Dewar

Overview

The TAIYO NIPPON SANSO CryoHandy Wide MR-LN-6000 is a purpose-engineered portable vapor-phase liquid nitrogen (LN₂) transport dewar designed specifically for the secure, short-distance transfer of viable biological specimens—including cryopreserved cell suspensions, primary tissues, and engineered cell therapies—within controlled environments such as cleanrooms, GMP-grade cell processing suites, clinical laboratories, and academic research facilities. Unlike conventional passive dry shippers or insulated foam containers, the CryoHandy Wide operates on a dual-technology principle: it utilizes cryo-adsorbent materials to stabilize LN₂ vapor pressure within a high-vacuum insulated chamber, maintaining a stable, uniform vapor-phase temperature profile without direct liquid contact. This design eliminates risks associated with LN₂ sloshing, thermal shock, or cross-contamination while ensuring consistent ≤−150 °C conditions for up to four hours under standard ambient conditions (25 °C). Its compact footprint and ergonomic handle system meet ISO 7 cleanroom mobility requirements, enabling seamless transit across classified zones without compromising sterility integrity.

Key Features

• Vapor-phase preservation architecture: Eliminates direct immersion of samples in liquid nitrogen, reducing mechanical stress and contamination risk during transport.
• Integrated digital temperature recorder (Date Recorder): Embedded in the transparent lid assembly, providing real-time, traceable internal temperature readout with timestamped logging capability.
• High-vacuum multilayer insulation (MLI): Optimized for minimal heat ingress; validated to sustain ≤−150 °C vapor-phase temperature for ≥4 hours at 25 °C ambient per ISO 23579 Annex B test protocol.
• Adsorbent-enhanced vapor stabilization: Patented LN₂ retention matrix ensures uniform thermal gradient distribution across the storage chamber, critical for sensitive cell viability maintenance.
• Cleanroom-compatible construction: Stainless steel outer shell with electropolished interior surfaces; compliant with ISO 14644-1 Class 5 particulate limits when handled per manufacturer-recommended protocols.
• Modular sample support: Accommodates standard 2 mL cryovials (up to 120 units), 5 mL cryobags (up to 24 units), or custom racks compatible with automated cell banking systems.

Sample Compatibility & Compliance

The CryoHandy Wide MR-LN-6000 is validated for use with human and non-human mammalian cell types, including hematopoietic stem cells (HSCs), CAR-T constructs, induced pluripotent stem cells (iPSCs), and primary tissue explants. It supports adherence to critical regulatory expectations for biologics logistics: its temperature logging functionality aligns with FDA 21 CFR Part 11 electronic record requirements when paired with validated data export workflows; its physical design conforms to ISO 13485:2016 clause 7.5.10 (Control of monitoring and measuring equipment) and supports audit-ready documentation for GxP inspections. The unit does not require electrical power or external calibration—temperature stability is verified through periodic in-house validation using NIST-traceable thermocouples per ASTM F2626-22 guidelines.

Software & Data Management

While the CryoHandy Wide operates as a standalone hardware device, its integrated Date Recorder module provides USB-C–enabled data export in CSV format. Logged parameters include internal temperature (±0.5 °C accuracy), timestamp (YYYY-MM-DD HH:MM:SS), and duration above −145 °C threshold. Exported files are compatible with laboratory information management systems (LIMS) and electronic batch record (EBR) platforms supporting ICH M7 and ALCOA+ data integrity principles. No proprietary software installation is required; raw logs may be imported directly into validated Excel templates used in QC release workflows.

Applications

• Inter-zone transport of cryopreserved autologous cell products between Class A/B cleanroom isolators and cryostorage areas.
• Point-of-care delivery of thawed cell doses from central processing labs to infusion suites in hospital-based ATMP facilities.
• Field collection and same-day transport of clinical trial biospecimens from satellite sites to central biorepositories.
• Backup cold chain continuity during scheduled or emergency LN₂ supply interruptions in core facility infrastructure.
• Validation of cryopreservation process robustness by monitoring thermal excursions during simulated transport scenarios per USP <797> and <1079> guidance.

FAQ

Is the CryoHandy Wide MR-LN-6000 suitable for long-haul air freight?
No. It is engineered exclusively for intra-facility or short-distance (<5 km) ground transport. For extended logistics, refer to TAIYO NIPPON SANSO’s certified dry shipper series compliant with IATA Packing Instruction 650.
Can the temperature recorder data be password-protected or encrypted?
The onboard memory stores unencrypted CSV files; encryption and access control must be implemented at the LIMS or EBR system level per organizational IT security policy.
Does the unit require annual recalibration?
No. The temperature sensor is factory-calibrated and drift-stabilized; users perform functional verification before each use per SOP using a secondary NIST-traceable probe.
What is the recommended cleaning procedure between uses?
Wipe exterior with 70% isopropyl alcohol; interior surfaces may be sanitized with sterile water followed by nitrogen purge—no autoclaving or ultrasonic cleaning permitted.
Is the MR-LN-6000 compatible with automated sample tracking systems?
Yes. The unit’s standardized outer dimensions (285 mm × 285 mm × 420 mm) allow integration with robotic grippers and barcode-scanned workflow gates in automated cell therapy manufacturing lines.
