The BVV Large Refinement Filter is a stainless steel filtration system that provides large scale, high flow filtering, with greatly improved functionality compared to a traditional Buchner filter. Utilizing a collection base for vacuum assistance and storage of material, the Refinement Filter allows for benchtop filtration with a longer lifespan and ease of use.

***Note: Unit will come with 12" Single Pin Clamps for easier assembly/disassembly.

Key Features:

• Stainless steel design for greater thermal conductivity and improved lifespan

• Easy to clean and disassemble with Tri-Clamp stainless steel parts

• Small tabletop footprint with wide mouth design

• Secondary collection vessel for vacuum and storage of material

• Liquid dip tube for direct injection into rotary evaporator after filling

Key Specifications:

• Large 12" Diameter x 12" Height Funnel with 12" Filtration Plate
