Dolomite Bio Injection Valve and Sample Loop

Dolomite Bio has launched a Injection Valve and Sample Loop for single cell RNA sequencing workflows. The product is a complete four-way valve module which allow barcoded mRNA capture beads in lysis buffer to efficiently flow through the RNA-Seq chip. Its design and simple microfluidic connections enable seamless switching between the injection of the bead suspension and pumping of a driving fluid. This produces minimal dead volume and bead wastage compared to traditional syringe pump methods, the company said.
