Wet Digester B-440

The BUCHI Wet Digester B-440 is an ecological pre-incineration unit dedicated to ash determination in pharmaceutical raw materials, foodstuffs and other sample types. It enables parallel ashing of differently sized crucibles at minimal heat loss and supports programmable incineration protocols for reproducible results. A glass hood captures acid fumes, and with the optional Scrubber K-415 accessory harmful vapors are neutralized in four stages before release – dramatically reducing fume hood corrosion and environmental impact.

Key specifications:

• Temperature range: 10 - 600 °C

• Time range: 0 - 240 minutes

• Crucible capacity: 4 or 6 crucibles

• Accommodates differently sized crucibles simultaneously

• Programmable incineration profiles for reproducible digestion

• Integrated glass hood for acid fume capture

• Optional Scrubber K-415 – four-stage fume neutralization controlled via the digester interface

• Compliant with U.S. Pharmacopeia standards <281> and <733>

Applications:

• Ash determination in pharmaceuticals and raw materials

• Sulfated ash testing per USP 281, European and Japanese Pharmacopoeias

• Loss on ignition (LOI) determination

• Environmental sample pre-treatment

• Pre-incineration prior to trace metal analysis
