Unlike other manufacturers, Brandel uses a variable frequency sine wave drive to reduce pulsations inherent in other syringe pumps using pulsed stepping motor drives. Variable selection of flow rate is provided by a ten-turn potentiometer and counting dial with 1,000 divisions. You can also choose among five fixed rates of 0.375, 0.75, 1.5, 3.0 and 6.0 ml/min. The Syringe Pump can be used in any of three operating modes: • manually, as a stand alone unit; • start-stop remote, by TTL level signal or; • by remote: remote clock pulses for speed (delivery rate) and TTL level signals for direction, start and stop control. Models SYR-101 Syringe Pump BR-184X Density Gradient Fractionator The Brandel density Gradient fractionator for 5-40 ml liquid displacement (formerly Isco) produces a continuous absorbance profile as the gradient is collected in precisely measured fractions. Zones that are undetectable by other methods are resolved, and their exact locations plotted. Fractionation is performed by introducing a dense sucrose or other chase solution into the bottom of a centrifuged tube, thereby raising the gradient intact by bulk flow. Chase solution is injected either by piercing the bottom of the tube with a short needle, or through a needle from the top.
