Peristaltic pump with triangular channels and roller mechanism
A recently granted patent (Publication Number: US12011716B2) discloses a novel peristaltic pump design featuring a cartridge with channels having a triangular cross-section and a surface layer to seal off the channel openings. The pump includes a roller, crank-and-rocker mechanism, roller arm, and hinge with a spring. The pump is capable of transporting fluids with high precision, ranging from less than or equal to 1000 microliters to as low as 50 microliters, making it suitable for sample preparation tasks such as analysis, sequencing, or identification of biological materials like nucleic acids, proteins, and tissues.
Furthermore, the peristaltic pump allows for easy cartridge replacement, with the option to switch between different cartridges. Each pump cycle can transport a specific volume of fluid, ranging from greater than or equal to 1 µL to less than or equal to 10 µL, with a stroke length between 10 mm and 20 mm. The design ensures efficient fluid transport while maintaining a high level of precision, making it a versatile tool for various laboratory applications requiring accurate fluid handling capabilities.
