The new single-use Quattroflow® Microdosing QB2-SD Precision Pump operates entirely differently from the legacy line of Quattroflow products. Using the principle of positive displacement with a rotary action, the lightweight QB2-SD precisely transfers fixed cavities of liquid of 25 μl with a maximum flow rate of 2.7 L/hr around a rotor from inlet to outlet.
This provides high levels of precision without the need for additional sensors that are typically combined with peristaltic pumps. The pumps also generate a high vacuum capability and handle high viscosities accurately.
The system allows easy and rapid changeovers since the single-use pumps simply click in and out of a motor drive, which is especially convenient when wearing full PPE.
The QB2-SD Microdosing Precision Pump can be gamma irradiated up to 50 kGy with USP <88> Class VI certified materials, making it an ideal solution for handling biologics, including cells, proteins, mAbs, etc.
