Rollers

Rollers are laboratory mixing devices that keep liquid samples in gentle, continuous motion by rolling tubes or vessels on a set of rotating bars. They are used to resuspend cells, blood and other particle-laden fluids without the shear that vortexing introduces, which makes them a standard fixture in cell culture and sample preparation work. On Questpair, new, used and refurbished rollers are listed side by side across this category: of the 301 current entries, 88 percent of the listings are used. The 264 used units sit alongside 37 new ones from 12 verified suppliers and distributors in 8 countries. Prices run from EUR 49 to EUR 10.983, with an average around EUR 1.145.
