Boante BAT700-FS to BAT1200-FS Portable Cryogenic Storage Rack

Overview

The Boante BAT700-FS through BAT1200-FS series of portable cryogenic storage racks are engineered for high-density, ergonomic, and traceable sample management within ultra-low temperature (ULT) freezers and liquid nitrogen storage systems. These racks operate on a simple yet rigorously validated mechanical principle: gravity-stable vertical stacking of standardized cryogenic storage boxes (e.g., 81- or 100-slot formats), combined with integrated handle-based mobility and label-ready front-facing identification slots. Unlike static shelving or drawer-based systems, the portable rack design enables rapid retrieval, spatial reconfiguration, and audit-compliant batch movement—critical for biobanking workflows where sample integrity, chain-of-custody documentation, and freezer space optimization are governed by ISO 20387, CAP Biorepository Standards, and FDA 21 CFR Part 11–aligned data governance frameworks. Constructed entirely from cold-worked austenitic stainless steel, each rack maintains structural rigidity and dimensional stability across thermal cycles ranging from ambient to –196 °C.

Key Features

• Monolithic stainless steel construction (0.6–1.0 mm AISI 304-grade equivalent) ensures resistance to embrittlement, corrosion, and condensate-induced pitting in high-humidity ULT environments.
• Resistance spot welding at all structural joints—validated per ASTM F1527—for zero delamination or microfracture after >10,000 thermal cycles between –80 °C and +25 °C.
• Deburred and edge-polished layer trays eliminate glove abrasion and prevent accidental puncture of cryovial caps or tube seals during manual handling.
• Ergonomic top-mounted carry handle with reinforced mounting brackets supports safe two-handed transport of fully loaded racks (up to 12 layers × 100 vials = ~1.8 kg typical mass).
• Front-facing label groove (30 mm wide × 2 mm deep) accommodates standard barcoded cryotags or laminated index cards, enabling visual identification without rack removal from freezer compartments.
• Modular scalability: Racks are supplied as discrete units; multiple units may be aligned side-by-side or stacked vertically using optional interlocking spacers (sold separately) to maximize footprint efficiency in chest- or upright-style ULT freezers.

Sample Compatibility & Compliance

All models accept industry-standard 133 × 133 × 54 mm cryoboxes—whether paper-based (81-slot) or polypropylene (100-slot)—and support OEM-compatible alternatives including Nunc™, Thermo Scientific™, and Corning® formats. Custom configurations—including non-standard tray depths, angled labeling rails, or RFID-embedded base plates—are available under NRE-supported engineering agreements (lead time: 12–15 business days). The rack architecture complies with ISO 13485:2016 manufacturing controls and is routinely deployed in GLP- and GMP-regulated settings, including clinical trial biorepositories and vaccine development labs subject to WHO TRS No. 961 Annex 6 and EU Annex 15 requirements. No lubricants, adhesives, or polymer coatings are used—eliminating outgassing risks in sealed cryo-environments.

Software & Data Management

While inherently hardware-based, the Boante portable rack integrates seamlessly into digital sample tracking ecosystems. Its standardized footprint and consistent labeling orientation enable reliable OCR scanning by laboratory information management systems (LIMS) such as LabVantage, STARLIMS, and OpenText ALM. When paired with compatible cryobox barcode printers (e.g., Zebra ZD620C) and validated label stock (e.g., Brady BBP11), full traceability—from rack ID → box ID → vial position—is maintained without middleware. Audit trails generated during rack movement events (recorded manually or via handheld scanner logs) satisfy 21 CFR Part 11 electronic record requirements when hosted on validated LIMS platforms. Optional QR-code etching on rack side panels (available upon request) provides direct physical-to-digital linkage for mobile inventory reconciliation.

Applications

• Biobanking: High-throughput archival of human tissue, PBMCs, plasma, and genomic DNA across multi-site repositories.
• Vaccine Development: Cold-chain staging of antigen batches, adjuvant formulations, and potency assay controls in –80 °C ultrafreezers.
• Cell Therapy Manufacturing: QC release storage of cryopreserved CAR-T and MSC lots under cGMP Annex 1 environmental monitoring protocols.
• Diagnostic Reference Libraries: Organization of pathogen isolates (e.g., SARS-CoV-2 variants, influenza strains) for longitudinal stability testing per CLSI MM19-A3.
• Agricultural & Food Safety Labs: Long-term preservation of microbial cultures, seed germplasm, and allergen reference materials per ISO/IEC 17025 clause 7.5.3.

FAQ

Can these racks be autoclaved?
No. Autoclaving is incompatible with welded stainless steel structures exposed to repeated steam sterilization cycles; however, surface decontamination using 70% ethanol or 0.5% sodium hypochlorite is fully supported.
Do you provide rack calibration certificates?
Not applicable—these are passive mechanical storage devices with no metrological function; dimensional verification reports per ANSI/ASME B89.1.10M are available upon request.
Is liquid nitrogen immersion safe for extended periods?
Yes. All models have been tested for 72-hour continuous submersion in LN₂ vapor phase (–196 °C) with zero loss of tensile strength or weld integrity per ASTM E1820 Annex A5.
What is the maximum load per layer?
Each tray supports up to 1.2 kg uniformly distributed load (equivalent to 100 filled 2 mL cryovials), verified per ISO 14729 Annex D static load testing protocol.
Are replacement labels or accessories available?
Yes. Standardized 30 mm × 100 mm cryotag holders, stainless steel rack ID plates, and anti-slip silicone base pads are stocked and shipped globally within 3 business days.
