Digester for the food industry LMD-102

for environmental analysislaboratoryfor the pharmaceutical industry

Overview
Labotemp LMD-102 is a high-pressure microwave digestion system engineered for rapid, safe and reproducible sample preparation under elevated temperature and pressure. Designed for analytical laboratories, the LMD-102 accelerates digestion of complex matrices — environmental, food, pharmaceutical, petrochemical, geological, polymer and fiber samples — and supports workflows for ICP-MS, ICP-OES and AAS. The unit features a true Single-Reaction Chamber (SRC), automated pre-pressurization and comprehensive process control for traceable results.

Key benefits

• High-pressure digestion up to 200 bar and 300 °C for challenging matrices.
• Advanced automation and safety: automated lid sealing, hydraulic clamping, pressure balancing, automatic pressure relief and acid-gas discharge.
• Precise process control via Siemens PLC with real-time monitoring and network connectivity for remote diagnostics and data traceability (21 CFR Part 11 compatible).

Features

• Single-Reaction Chamber (SRC) design for uniform digestion conditions.
• Bottom-emission microwave heating for efficient energy distribution.
• Dual-cylinder hydraulic clamping and fully automated lid sealing.
• Automatic inert-gas pre-pressurization, pressure balancing and controlled relief.
• Platinum resistance temperature sensor with real-time temperature and heating-curve monitoring.
• Automatic acid-gas exhaust and vertical lift door for safe access.
• Biphasic steel cavity and PTFE/PFA-lined working compartment for corrosion resistance.
• Wi‑Fi and wired network connectivity, remote diagnostics and audit trail functions.

Applications

• Environmental monitoring and trace elemental analysis sample digestion.
• Food safety testing and residue analysis.
• Pharmaceutical quality control and regulatory testing.
• Petrochemical, geological and mining sample digestion.
• Materials research and academic laboratory sample preparation for ICP-MS, ICP-OES and AAS.
