Overview
The Nabertherm Heat-Resistant Glove (Part No. 491041101) is a purpose-engineered personal protective equipment (PPE) component designed exclusively for safe manual intervention during high-temperature operations involving Nabertherm muffle furnaces and compatible thermal processing systems. Constructed from multi-layered aluminosilicate ceramic fiber fabric—certified to withstand continuous exposure up to 900 °C—the glove provides critical thermal insulation while preserving dexterity and tactile feedback essential for precise handling of crucibles, sintering boats, and furnace linings. Unlike generic heat-resistant gloves, this OEM-specified accessory meets the dimensional tolerances and material compatibility requirements defined in Nabertherm’s furnace safety protocols, ensuring seamless integration with standard loading/unloading workflows in ISO/IEC 17025-accredited laboratories and GLP-compliant quality control environments.
Key Features
- Continuous-use thermal rating of 900 °C (1652 °F), validated per EN 407:2020 Annex A for contact heat resistance (Level C1)
- OEM-part-specific design ensures optimal fit with Nabertherm furnace door mechanisms and sample-handling tools
- Reinforced aluminosilicate fiber shell with double-stitched seams and abrasion-resistant leather palm overlay for mechanical durability
- Ergonomic curvature and finger articulation support prolonged use without hand fatigue during repetitive loading cycles
- Non-shrinking, non-embrittling structure after repeated thermal cycling between ambient and 900 °C
- Low thermal mass enables rapid cooldown upon removal from furnace proximity, reducing residual heat transfer risk
Sample Compatibility & Compliance
This glove is intended for direct handling of ceramic, alumina, and quartz laboratory ware—including crucibles (e.g., Pt, Al₂O₃, ZrO₂), sintering trays, and ashing boats—used in gravimetric analysis, loss-on-ignition (LOI), and thermal decomposition procedures. It complies fully with European PPE Regulation (EU) 2016/425 and carries CE marking under Category III (complex design, high-risk applications). Certification documentation includes full traceability to EN 407:2020 test reports covering flammability (A1), contact heat (C1), convective heat (B1), radiant heat (E1), and small splashes of molten metal (F1). The glove is routinely deployed in laboratories adhering to ASTM E1131, ISO 11358, and USP methodologies where operator safety must be demonstrably integrated into method validation protocols.
Software & Data Management
As a passive PPE component, this glove does not incorporate electronic or software-based functionality. However, its use is formally documented within laboratory safety management systems (LSMS) and integrated into digital audit trails maintained by LIMS platforms such as LabWare LIMS, Thermo Fisher SampleManager, or Agilent OpenLab ECM. Institutions subject to FDA 21 CFR Part 11 compliance maintain glove issuance logs—including part number (491041101), calibration interval (thermal performance verification every 6 months), and user assignment records—as part of their GxP-mandated equipment qualification files. Nabertherm provides a Certificate of Conformance (CoC) with each unit, listing batch-specific thermal stability test data and EN 407 certification reference numbers.
Applications
- Manual insertion and extraction of samples during ashing procedures per AOAC 923.03 and EPA Method 2540E
- Handling of red-hot platinum crucibles during quantitative gravimetric sulfate determination (ASTM D129)
- Safe manipulation of ceramic setters and kiln furniture during materials research in oxide ceramics development
- Thermal stabilization of furnace interior components during maintenance shutdowns at temperatures up to 900 °C
- Supporting ISO 5660-1 cone calorimeter sample preparation under controlled high-temperature pre-conditioning
FAQ
Is this glove suitable for intermittent contact with 1000 °C surfaces?
No. This glove is rated for continuous exposure up to 900 °C and short-term contact up to 1000 °C for ≤5 seconds, as verified under EN 407 Clause 4.6 (contact heat test). Prolonged exposure above 900 °C compromises fiber integrity.
Can it be cleaned in an autoclave?
No. Autoclaving induces hydrothermal degradation of aluminosilicate fibers. Cleaning is limited to dry brushing and compressed air; solvent wiping with isopropanol is permitted only on the leather palm overlay.
Does Nabertherm offer size customization?
Standard sizes are S, M, L, and XL, conforming to EN 420:2020 anthropometric dimensions. Custom sizing requires minimum order quantities and extended lead times—contact technical support for OEM procurement pathways.
How often should thermal performance be re-verified?
Per Nabertherm’s PPE Maintenance Bulletin MB-491041101 Rev. 3, visual inspection is required before each use; formal thermal resistance verification via accredited third-party testing is mandated every six months or after 200 cumulative furnace cycles, whichever occurs first.
