Buchi Packing B-440 049981

The Wet Digester B-440 is a laboratory pre‑incineration unit designed for ecological and safe pre‑incineration and ash determination of different sample types. It provides programmable temperature/time profiles for reproducible determination of ash, sulfated ash and loss on ignition, and captures acid fumes with a glass hood that can be connected to the Scrubber K‑415 for neutralization and removal of harmful vapors.

Key Features:

• Model: B-440; manufacturer part code: 049981
• Adjustable temperature range: 10–600 °C
• Adjustable time range: 0–240 minutes
• Holding capacity: 4 or 6 crucibles (parallel ashing)
• Programmable and storable temperature/time profiles
• Glass hood for fume capture; compatible with Scrubber K-415
• Compliance: U.S. Pharmacopeia <281> and <733>

Advantages:

• Reproducible results through programmable and storable temperature/time profiles for consistent ash and loss on ignition determinations
• Enhanced safety by capturing acidic fumes under a glass hood and enabling neutralization/removal via the Scrubber K‑415 to reduce corrosive vapors and environmental emissions
• Fast and flexible processing with rapid heating of individual crucibles and the ability to ash multiple, differently sized crucibles in parallel
• Regulatory suitability for pharmaceutical and raw material testing through compliance with USP <281> and <733>
