Products Rotary pump PSG Biotech Quattroflow QB2-SD single-use micropump is ideal for microdosing applications Related To: Watson Marlow Fluid Technology Solutions Nov. 30, 2023 3 min read Add Us On Google PSG Biotech, a provider of pump, flow- sensor and flow-measurement technologies for use in life science and biopharmaceutical process applications, and a brand of PSG, recently announced the availability of the new Quattroflow QB2-Standard (QB2-SD) Single-Use Precision Micropump. The Quattroflow pump family is expanding with the launch of its first QB Series micropump, the QB2-SD. This model is the smallest size in the family of single-use, lightweight and compact rotary microdosing pumps designed for precision and can be used to transfer delicate biologics . The QB2-SD has a minimum resolution of 25 μl and flow rates up to 2.7 liters per hour (91.3 fluid ounces per hour), which makes the QB2-SD pump ideal for liquid-handling operations requiring precise and delicate dosing of products that can be found in , laboratory and small-scale upstream and downstream applications. The Quattroflow QB2-SD Single-Use Precision Micropump works on the positive displacement principle where fixed cavities of liquid are transferred from inlet to outlet around a rotor. This creates high vacuum levels of -0.6 bar (-9 psi) and exhibits back-pressure capabilities up to 0.2 bar (2.9 psi). Lightweight at 6.4 g (0.013 lb.), this single-use pump is highly compact at 38 mm wide (including barbs) and 30 mm high with a depth of only 17 mm , which offers a very low hold-up volume. This micropump features a bi-directional pumping motion, is compatible with gamma irradiation, and can handle viscosities up to 500 cP. Constructed with USP Class VI-certified materials such as MBS, HDPE, and silicone, it meets stringent quality standards. Biopharma certifications include Particulate Testing (sub-visible testing per USP 788), Microbial Ingress, Endotoxin (USP 85), and Bioburden (ISO 11737-1). In addition to the QB2-SD pump, PSG Biotech offers a fully integrated drive device called Q-Drive-Alpha for evaluation, production, and laboratory use. The Q-Drive-Alpha features a stainless-steel body and a 7 inch color touchscreen for programming desired functions such as speed, flow, dose volume, self-priming, cycling, and reverse.
