Sample concentrator BJP 10

proteinlaboratorybenchtop

Product Overview
The BJP 10 is a benchtop static concentrator for laboratory and clinical research use. It concentrates samples up to 10 ml without requiring a centrifuge or additional instrumentation. The dead-stop design enables maximal concentrate recovery and facilitates sample withdrawal without glass Pasteur pipettes. Concentration factors up to 200× may be achieved depending on sample characteristics.

Key Features

• Benchtop static concentrator for laboratory use
• Operates without centrifuge or additional equipment
• Dead-stop design for maximum concentrate recovery and easy sample removal
• Membranes: polyethersulfone (PES) with various MWCO options (example shown: 7,500 MWCO)
• Reservoir material: styrene-acrylonitrile; active membrane area: 25 cm²; dead-stop volume: 50 µl

Applications

• Concentration of biological samples and dilute protein solutions
• Concentration and partial purification of antibodies

Performance (time to concentrate at 20°C and solute recovery %)
Example results for 10 ml start volume using 7,500 MWCO PES:
BSA 1.0 mg/ml (66,000 MW) — 10× concentration: ~100 min (recovery 92%); 50× concentration: ~210 min (recovery 90%).
IgG 0.25 mg/ml (160,000 MW) — 10× concentration: ~110 min (recovery 78%); 50× concentration: ~130 min (recovery 74%).
