Below is a list of Ultracentrifuge manufacturers from Northvale, New Jersey. Ultracentrifuges are scientific instruments designed to facilitate the rapid rotation of objects and suspensions around a fixed axis. Completing up to fifty thousand revolutions per minute, the force created by these mechanisms may be as great as twenty thousand times that of normal gravity. This extreme acceleration provides ample opportunity for research and exploration as suspensions, solutions and even cellular organelles can be separated and sorted based on density and viscosity.
