Thermo Fisher Scientific 4105MAT Cap Handling System for Nunc 2D-Encoded Cryovials

Overview

The Thermo Fisher Scientific 4105MAT Cap Handling System is a modular, laboratory-engineered solution designed to ensure consistent, contamination-minimized, and ergonomic cap manipulation across Nunc 2D-encoded cryogenic storage vials—including Cryobank™ and Bank-it™ formats. Engineered for precision and reproducibility in biobanking, clinical sample processing, and high-throughput screening workflows, the system comprises three interoperable configurations: a manual hand-held screwdriver, an 8-channel electric capper/de-capper, and the fully automated Capit-All series. Each variant operates on mechanical torque control principles—leveraging calibrated rotational force and axial alignment—to achieve uniform sealing integrity and prevent cross-threading or vial deformation. The system’s design prioritizes compatibility with ISO/IEC 17025-compliant sample handling environments and supports GLP/GMP-aligned documentation requirements through traceable actuation cycles (in IS-enabled models).

Key Features

• Three-tiered operational flexibility: manual (handheld screwdriver), semi-automated (8-channel electric unit), and fully automated (Capit-All and Capit-All IS platforms)
• 8-channel electric capper/de-capper completes simultaneous cap actuation on eight 2 mL or 5 mL Nunc Cryobank vials in ≤4 seconds per cycle
• Rechargeable lithium-ion battery provides ≥20 full rack operations (96-tube racks) per charge; 90-minute full recharge time with hot-swap capability (operates while charging)
• Configurable dual-mode operation: 8-channel mode for standard 96-well racks and 4-channel mode optimized for 48-well configurations
• Capit-All platform executes full 96-tube rack de-capping or capping in ≤10 seconds via tactile push-button interface
• Capit-All IS variant integrates RS232 serial communication for external command integration, enabling synchronization with LIMS, robotic arms, or custom scripting environments
• All components feature chemically resistant housing (IP54-rated) and are validated for use in controlled cold rooms (–20 °C to +25 °C ambient operating range)

Sample Compatibility & Compliance

The 4105MAT system is exclusively validated for Nunc 2D-encoded cryovials: Cryobank™ (2 mL and 5 mL formats) and Bank-it™ storage tubes. It accommodates standard ANSI/SLAS footprint racks (e.g., 96-well SBS format) and maintains dimensional tolerance compliance per ASTM D4169-23 for mechanical handling durability. The torque delivery profile meets ISO 8536-5 specifications for pharmaceutical vial closure integrity. All electric and automated units undergo EMC testing per IEC 61326-1 and safety certification per UL 61010-1. For regulated environments, Capit-All IS supports audit-trail generation (timestamped event logs) and user-access controls aligned with FDA 21 CFR Part 11 requirements when integrated with compliant software layers.

Software & Data Management

While the base 4105MAT configurations operate without embedded firmware, the Capit-All IS model supports ASCII-based command protocols over RS232 for bidirectional communication. Compatible with Windows/Linux host systems, it accepts discrete commands (e.g., “CAP ON”, “DECAP ALL”, “STATUS?”) and returns machine-state responses including cycle count, battery level, and error codes. When deployed within validated IT infrastructures, raw log files can be ingested into ELN or LIMS platforms supporting CSV/JSON ingestion. No proprietary software installation is required; configuration and monitoring are performed via terminal emulation or custom Python/Node.js scripts using standard serial libraries.

Applications

• Biorepository operations requiring rapid, low-error-rate access to frozen samples during retrieval, aliquoting, or reformatting
• QC/QA laboratories performing stability studies where repeated vial opening/closing must preserve seal integrity across hundreds of timepoints
• Genomics core facilities integrating cap handling into automated nucleic acid extraction or library prep workflows
• Clinical trial sample banks maintaining chain-of-custody compliance through timestamped, operator-logged cap events
• Cell therapy manufacturing suites adhering to EU Annex 1 and USP guidance for closed-system manipulation of cryopreserved products

FAQ

Is the 4105MAT compatible with non-Nunc vials or third-party 2D-barcoded tubes?
No—mechanical interface geometry and torque calibration are specific to Nunc Cryobank and Bank-it tube thread profiles and cap dimensions.
Can the 8-channel electric unit be used outside of a biosafety cabinet?
Yes, provided ambient humidity remains below 80% RH and no condensation forms on internal mechanisms; however, routine decontamination with 70% ethanol is recommended after BSC use.
Does Capit-All IS support Ethernet or USB connectivity?
No—only RS232 serial interface is provided; optional USB-to-serial adapters may be used but are not supplied or validated by Thermo Fisher.
What maintenance is required for long-term reliability?
Quarterly inspection of drive gear lubrication and cap alignment guides; replacement of consumable O-rings every 12 months or after 10,000 actuation cycles.
Are calibration certificates available for torque output verification?
Yes—NIST-traceable torque calibration reports (per ISO/IEC 17025) are available upon request at time of purchase or as a post-installation service.
