Digester for the pharmaceutical industry B-440

laboratoryfor environmental analysiswet

Overview
The Wet Digester B-440 is an ecological pre-incineration unit designed for ash determination across various sample types. It offers a wide programmable temperature range up to 600 °C and reproducible, storable temperature/time profiles to support standardized ash, sulfated ash and loss on ignition procedures.

Key facts

• Adjustable temperature range: 10 - 600 °C
• Adjustable time range: 0 - 240 min
• Holding capacity: 4 or 6 crucibles

Benefits

• Fast and flexible: Each crucible rapidly reaches the set digestion temperature; supports parallel ashing with different crucible sizes for efficient throughput.
• Safe: Glass hood captures acid fumes; integration with Scrubber K-415 enables withdrawal and neutralization of acid fumes to reduce corrosion and environmental impact.
• Reproducible: Programmable and storable temperature/time profiles (programmable incineration ramps) ensure consistent digestion suitable for regulated environments.

Features

• Ecological pre-incineration design optimized for ash determination workflows.
• Programmable temperature/time profiles with storage for individual methods.
• Wide temperature range up to 600 °C and time control up to 240 min.
• Supports 4 or 6 crucible configurations.
• Glass hood for fume capture; option to connect and control Scrubber K-415 for automatic neutralization of fumes.
• Parallel ashing capability and minimal heat loss design.
• Suitable for determination of ash, sulfated ash and loss on ignition.

Accessories & related instruments

• Activated charcoal granules (150 g) for adsorption and aerosol recondensation.
• Scrubber K-415 – fume neutralization unit (integrates with the B-440).

Applications

• Environmental analysis: sulfated ash, ash determinations.
• Pharmaceuticals and raw materials: ash, sulfated ash and loss on ignition according to pharmacopeia methods.

Technical specifications

• Temperature range: 10 °C to 600 °C
• Time range: 0 to 240 minutes
• Crucible capacity: configurable for 4 or 6 crucibles
• Programmable and storable temperature/time profiles (incineration ramps)
• Fume management: glass hood captures acid fumes; compatible with Scrubber K-415 for neutralization
• Measured / supported analyses: ash, sulfated ash, loss on ignition
• Compliance: meets requirements for controlled/regulatory environments (references on page to USP procedures)
