Positive displacement pipettes are a highly advantageous tool in laboratory settings, offering unparalleled accuracy when handling viscous or volatile substances. With each stroke of our Rainin capillary-piston, a precise volume is dispensed, ensuring exact executions throughout the entire process. This not only minimizes errors but also reduces re-work time. Moreover, positive displacement pipetting places safety at the forefront by mitigating the risk of contamination and exposure to hazardous materials. Disposable tips are replaced after each use, thereby preventing cross-contamination and the need for repeated attempts. The combined benefits of accuracy, safety, and efficiency make positive displacement pipetting the preferred method for precise liquid handling, meriting their wide use in research, clinical testing, and other scientific endeavors.
