Overview
The Nabertherm Steel Collection Tray is a precision-engineered consumable accessory designed exclusively for integration with Nabertherm’s industrial-grade muffle furnaces — including the L, LT, LE, LV, and LVT series. Constructed from austenitic stainless steel with optimized high-temperature oxidation resistance, this tray serves two primary functional roles: (1) physical containment of crucible residues, ash, or molten spillage during thermal treatment; and (2) structural support for uniform heat distribution across the furnace chamber floor. Unlike generic trays, it is dimensionally calibrated to match the internal geometry and load-bearing specifications of each furnace model, ensuring full compatibility with Nabertherm’s proprietary heating element layout, insulation configuration, and door sealing mechanism. Its design adheres to the fundamental thermomechanical principles governing muffle furnace operation: minimizing thermal bridging, preventing localized hot spots, and preserving furnace calibration integrity over repeated thermal cycles.
Key Features
- Material specification compliant with DIN 1.4845 (X10CrNiSi25-20), offering stable mechanical strength up to 1200 °C in oxidizing atmospheres
- Surface-finished via controlled passivation to inhibit scale adhesion and facilitate post-run residue removal
- Reinforced peripheral rim and cross-braced base structure to resist warping under thermal cycling between ambient and operational temperatures
- Part-number-specific fitment ensures zero interference with furnace thermocouple placement, gas flow paths (in optional atmosphere-controlled variants), or programmable ramp/soak profiles
- CE-certified as a safety-critical component under EU Machinery Directive 2006/42/EC, with documented conformity to EN 60519-1 for electrical equipment used in heating applications
Sample Compatibility & Compliance
The tray is not a standalone analytical instrument but a certified system-level component integral to validated furnace workflows. It maintains full compatibility with standard ceramic crucibles (alumina, silica, zirconia), platinum ware, and graphite boats used in gravimetric analysis, ash content determination (ASTM D3174, ISO 1171), loss-on-ignition (LOI) testing, and thermal decomposition studies. When deployed within Nabertherm furnaces operating under GLP or GMP environments, the tray contributes to method reproducibility by eliminating uncontrolled particulate shedding and maintaining consistent cavity emissivity. Its material traceability (batch-coded upon request) supports audit readiness for FDA 21 CFR Part 11–aligned quality systems where hardware provenance is required.
Software & Data Management
As a passive mechanical component, the Steel Collection Tray does not interface with Nabertherm’s THERMOCOMFORT® control software or the optional LabCom® data logging suite. However, its correct installation is prerequisite for maintaining the thermal stability profile referenced in furnace calibration certificates (e.g., ISO/IEC 17025-accredited calibrations). Users must verify part number alignment during preventive maintenance logs — a step routinely captured in Nabertherm’s service documentation templates and integrated into laboratory asset management systems (LIMS) via configurable accessory tracking fields.
Applications
- Residue containment during ashing of organic matrices (food, feed, pharmaceutical excipients, polymers)
- Support platform for sequential high-temperature treatments in metallurgical sample preparation (e.g., pre-oxidation prior to XRF fusion)
- Thermal barrier between furnace floor and reactive melts in ceramic sintering protocols
- Facilitation of clean transfer in multi-step thermal protocols requiring intermediate weighing without chamber cooldown
- Reduction of maintenance frequency for furnace insulation and heating elements by preventing abrasive or corrosive deposit accumulation
FAQ
Is this tray compatible with non-Nabertherm muffle furnaces?
No. Dimensional tolerances, weight limits, and thermal expansion coefficients are specific to Nabertherm’s furnace chamber architecture. Use with third-party equipment voids warranty and compromises safety certification.
Can the tray be cleaned in an ultrasonic bath?
Yes — only with neutral pH aqueous solutions. Avoid chlorinated or acidic cleaners, which may compromise the passive oxide layer and accelerate intergranular corrosion at elevated temperatures.
Does the tray require periodic recalibration?
No. As a passive component, it does not require calibration. However, visual inspection for warping, cracking, or severe scaling is recommended before each use per Nabertherm’s Maintenance Schedule A-3.
Are replacement trays supplied with material test reports (MTRs)?
Yes — upon request and subject to minimum order quantity, batch-specific MTRs conforming to EN 10204 3.1 are provided, documenting chemical composition and room-temperature tensile properties.
