Ultralab™ systems, composed of Ultrareservoir™ containers and Ultrapump™ II pumps, are designed as a rapid, efficient replacement of dialysis for buffer exchange and desalting of macromolecules.

• Efficient replacement of dialysis
• Airtight lid
• Siphoning action

Systems are specifically designed for use with Ultrasette™ lab tangential flow devices (see 29300-988 series).

Ultrapump™ II has a 0 to 600 rpm rated, ¹/₁₀ hp motor with continuous-duty rated drive, and 0 to 10 dial speed control. Pump size: 16.3×34×13.7 cm (6¹³/₃₂×13¹³/₃₂×5¹³/₃₂"). Maximum pressure: 2.8 bar (40 psi) intermittent, 1.8 bar (25 psi) continuous. Min. recirculation volume: 20–30 ml. Ultrareservoir™ is constructed from acrylic with EPR lid O-ring, stainless steel gauge, and polypropylene valves, barb connectors, and lid.

Airtight lid and siphoning action maintain constant sample volume and eliminate the need for multiple buffer exchanges. Sample port allows maximum sample recovery without decanting. Peristaltic pump action excludes air in the system, reduces foaming, and minimizes shear of sensitive molecules.
