The Duo Digital Dispenser™ Enables Low Volume Delivery Of Proteins In Aqueous Solutions

Delivering proteins and aqueous solutions at ultra-low volumes, without surfactants, is now possible with the Duo Digital Dispenser™ and its T8sf and D4sf cassettes. This advancement eliminates the need for surfactants, which can interfere with sensitive assays or compromise compound stability. The system enables precise dispensing down to 8 picoliters for aqueous fluids and 10 picoliters for proteins, with consistent CVs under 8% across a range of volumes. Ideal for antibody-drug conjugate testing, immunoassays, and other surfactant-sensitive workflows, the dispenser supports a wide range of plate formats and fluid types. With no calibration required and minimal contamination risk, it streamlines workflows while preserving sample integrity. For labs seeking reproducibility and flexibility in low-volume dispensing, this application note offers a detailed look at performance metrics and use cases.
