Product Description
Load the right tubes with confidence using racks and caps built to match OHAUS swing-out centrifuge rotors and buckets. Each rack is sized for a specific tube volume and diameter, so samples sit securely and balance properly during every run.
This listing is for OHAUS item number 30314901: Screw Cap for Rack of 250 mL Centrifuge Rotor, Pack of 2. Racks are supplied in pairs so opposing bucket positions can be loaded symmetrically, and screw caps seal buckets or rotor racks to help contain samples. The range also includes rotor lubricant for routine maintenance of rotor contact surfaces. Check tube volume, diameter and bottom style against the listing before ordering. Order it from LIGHT LABS alongside the rest of your OHAUS balances, weights and lab equipment.
