The QB2-SD Single-Use Precision Micropump from Quattroflow is a game-changer in liquid-handling operations, offering high-precision microdosing for a variety of applications such as cell and gene therapy, laboratory work, and small-scale upstream and downstream processes. This innovative pump operates on the principle of positive displacement with a rotary action, allowing for the gentle transfer of fixed liquid cavities of 25 μl with a maximum flow rate of 2.7 L/hr (0.7 US gph).

Key features of the QB2-SD pump include its lightweight design, high accuracy without the need for additional sensors, high vacuum capabilities and the ability to handle high viscosities. The pump is single-use and can be easily clicked in and out of a motor drive, facilitating quick changeovers, particularly in environments where full personal protective equipment (PPE) is required.
