Brookfield GT-400-40 Position Microwave Digestion Vessel Set

Overview

The Brookfield GT-400-40 Position Microwave Digestion Vessel Set is a precision-engineered consumable system designed for high-throughput sample preparation in analytical laboratories performing trace metal analysis, environmental testing, food safety screening, and pharmaceutical quality control. Engineered to operate within certified microwave digestion systems (e.g., CEM MARS 6, Anton Paar Multiwave PRO, Milestone ETHOS UP), this vessel set implements closed-vessel acid digestion under controlled temperature, pressure, and power conditions—enabling complete mineralization of organic matrices while minimizing analyte loss, contamination, or volatilization. Each vessel features a multi-layered construction comprising high-purity quartz inner liners, reinforced PTFE–PFA composite bodies, and torque-sealed TFM® caps with integrated pressure relief mechanisms compliant with ISO/IEC 17025 method validation requirements. The 40-position configuration supports batch processing aligned with ASTM D5173, EPA Method 3052, and USP heavy metals procedures.

Key Features

• 40-position modular rack design compatible with standard rotor diameters (180–200 mm) and automated carousel loading systems
• Quartz inner liners (99.995% SiO₂) resistant to HF–HNO₃–HCl mixtures up to 260 °C and 80 bar internal pressure
• PTFE–PFA hybrid vessel bodies offering superior chemical inertness, low extractables, and thermal stability from –200 °C to +260 °C
• TFM® sealing caps with dual-stage pressure release (mechanical rupture at 100 bar ±5%) and real-time pressure monitoring ports
• Laser-etched alphanumeric identifiers on each vessel base for unambiguous sample traceability and LIMS integration
• Pre-cleaned and certified for ≤0.1 ng/mL blank levels (measured via ICP-MS for As, Cd, Cr, Pb, Hg, Ni)

Sample Compatibility & Compliance

The GT-400-40 vessel set accommodates solid, semi-solid, and liquid samples across diverse matrices—including soil, sediment, biological tissue, polymer composites, catalysts, and herbal extracts—with maximum recommended sample mass of 0.5 g (organic) or 1.0 g (inorganic). All components meet ISO 9001:2015 manufacturing controls and are supplied with CoA (Certificate of Analysis) documenting heavy metal blanks, dimensional tolerances (±0.15 mm), and pressure cycle endurance (≥500 autoclave cycles). The system conforms to GLP documentation standards and supports audit-ready workflows required under FDA 21 CFR Part 11 when paired with validated digestion software platforms.

Software & Data Management

While the GT-400-40 vessels themselves are hardware components, their use is fully integrated into vendor-specific microwave digestion software suites (e.g., CEM iWave, Anton Paar NovaControl). Each vessel’s unique identifier enables automated sample mapping, digestion protocol assignment, and post-run data linkage to instrument logs. The physical design supports RFID tag embedding (optional upgrade) for full chain-of-custody tracking. Raw pressure/temperature/time profiles generated during digestion are exportable in .csv and .xml formats compatible with LIMS, ELN, and statistical process control (SPC) tools.

Applications

• Multi-element quantification by ICP-OES and ICP-MS following EPA 6020B and ISO 17294-2 protocols
• Digestion of NIST SRM reference materials (e.g., 1573a Tomato Leaves, 1643f Trace Elements in Water) for lab accreditation
• Preparation of catalyst ash residues prior to XRF or AAS analysis per ASTM D7348
• Pharmaceutical excipient testing per USP / elemental impurities guidelines
• Regulatory compliance testing for RoHS, WEEE, and China RoHS restricted substances

FAQ

Are GT-400 vessels compatible with non-Binzhenghong microwave digesters?

Yes—mechanical and thermal specifications align with international rotor interface standards (DIN 12878, ISO 13485 Annex B); compatibility verification is recommended per instrument manufacturer’s accessory list.
What cleaning protocol is required between uses?

Rinse sequentially with 10% HNO₃, deionized water (18.2 MΩ·cm), and acetone; dry in Class 100 laminar flow hood. Autoclaving at 121 °C is permitted but not required for routine reuse.
Can vessels be reused after digestion with hydrofluoric acid?

Quartz liners may be reused up to three times with HF-containing mixtures if inspected microscopically for etching; PTFE–PFA bodies are single-use after HF exposure per ASTM E2921 guidance.
Is a validation package available for GMP environments?

Yes—Binzhenghong provides IQ/OQ documentation templates, pressure calibration certificates, and blank test reports upon request for regulated laboratory implementation.
