Desalting/Buffer Exchange 1 Concentrate sample to desired level or at least 5´. 2 Empty filtrate container. 3 Refill concentrator with an appropriate buffer. 4 Concentrate the sample again and repeat the process until the concentration of the contaminating species is sufficiently reduced. Typically three wash cycles will remove 99% of initial salt content. See Notes on next page. Instructions – 15 mL Concentrators Equipment required Centrifuge Rotor type Minimum rotor angle Rotor cavity 30,000 Molecular Weight Cut-Off (MWCO) 15 mL Spin Concentrator, Part No. 5188-2799 15 mL Spin Concentrators, pack of 10 Swing bucket or Fixed angle 25° To fit 30 x 114 mm conical bottom tubes or 29 x 104 mm round bottom tubes (50mL) 1,000 g 2,000 g 3,000 g Minimum effective speed Recommended speed Maximum speed Concentrate recovery Pipette type Fixed or variable volume Recommended tip Thin gel loader type Technical specifications Concentrator sample volume capacity Swing bucket rotor 2-15 mL Fixed angle rotor 2-8 mL Dimensions Total Length 76 mm Width 25.5 mm Active Membrane Area 4 cm2 Hold-up volume of membrane <20 µL Dead stop volume 50 µL pH range pH 1 – 9 Materials of construction Body Polycarbonate Filtrate vessel Polypropylene Concentrator cap Polycarbonate Membrane Polyethersulfone Concentrating Proteins with 15 mL Concentrators: 1 Fill concentrator with sample within the working volume capacity range noted in the table above, taking care not to touch the membrane surface, and then close the hinged lid (ensure that the lid is fully seated). 2 Place concentrator into 50 mL centrifuge tube (filtrate collection vessel – not supplied, user must provide). 3 Insert assembled concentrator into centrifuge (when fixed angle rotors are used, angle the concentrators so that the printed windows face upwards/outwards). Spin at recommended speeds, taking care not to exceed the maximum g force indicated in the table above (20-40 minutes is common). 4 Once the desired concentration is achieved, remove assembly and recover sample from the bottom of the concentrate pocket with a pipette.

Re-use is not recommended. · For research use only. · Select the most appropriate membrane cut-off for your sample. For maximum recovery, select a MWCO at least 50% smaller than the molecular size of the species of interest. · These concentrators are designed for use with biological fluids or aqueous solutions only, not for organic solvents or strong acids or bases. · Flow rates are affected by MWCO, porosity, sample size, concentration, viscosity, centrifuge force, and temperature. Adjust centrifuge force and time accordingly for your samples. · Do not autoclave. Sterilize with a 70% ethanol solution.
