How do you clean and sterilize an electronic pipette?

Cleaning an electronic pipette usually involves wiping the exterior with mild detergents or disinfectants and occasionally removing the shaft or ejector components for a more thorough cleaning. Most models can tolerate routine exposure to common lab cleaning agents like 10% bleach, 70% ethanol, and UV light, although autoclaving depends on the specific design and manufacturer guidelines. We have created a lab poster with guidelines for cleaning Rainin pipettes.

What are the most common errors when using electronic pipettes and how can they be avoided?

Common pipetting errors often come from technique issues such as holding the pipette at an incorrect aspiration angle or immersing the tip too deeply, both of which can affect accuracy and reproducibility. Reviewing proper technique and following Rainin Good Pipetting Practice (GPP ) guidelines can significantly reduce these problems.

How do you troubleshoot common issues with electronic pipettes?

Most common issues like inconsistent volumes, dripping, or leaking usually come from tip fit problems, worn parts, or calibration drift rather than the electronics themselves. Making sure the correct tips are used and keeping up with routine calibration and pipette service will often fix the problem. Software issues are usually handled by checking the user manual or contacting technical support.

What safety precautions should be taken when using electronic pipettes?

Users should follow their institutional safety guidelines, including wearing appropriate PPE, avoiding over-immersion of the shaft, preventing aerosol generation, and handling hazardous liquids within biosafety guidelines. As with any pipette, proper tip disposal and routine cleaning are essential.

Choosing an Electronic Pipette

Selecting the right electronic pipette depends on your volume needs, how intuitive the software feels, overall ergonomics, weight, tip compatibility, and whether the pipette fits smoothly into your daily workflows. Many labs also look at durability, service options, and how easy it will be to train new users.

When working with challenging liquids such as highly viscous or highly volatile solutions, a positive displacement repeater pipette is often the better choice because it delivers more reliable performance.

What Are the Advantages of Using an Electronic Pipette over a Manual Pipette?

Electronic pipettes are essentially digital versions of handheld instruments commonly used in academia, biotech, pharmaceutical, and other labs to transfer precise amounts of liquid from one container to another.

Electronic pipettes use a motorized system to control aspiration and dispensing, allowing for consistent settings and repeatable pipetting actions. Instead of relying on manual force, the pipette automates plunger movement for higher reproducibility. By eliminating manual force, electronic pipettes reduce hand strain, improve reproducibility, and make high-throughput or repetitive workflows easier by automating aspiration, dispensing, and mixing steps.

Because manual technique has more inherent variability, especially during repetitive tasks, electronic pipettes generally provide higher accuracy and reproducibility by reducing user-dependent variation. By enabling users to create and save frequently used pipetting protocols, they can also reduce errors and increase reproducibility.

Rainin Electronic Pipettes: Pipetting Innovation Since 1984

Rainin has always been at the forefront of electronic pipette innovation, releasing the world’s first electronic pipette in 1984 and has continued to push the technology forward delivering pipettes with great performance, reliability, and ergonomics.

Rainin electronic pipettes feature large color screens, joystick control, and intuitive graphic interfaces to make moving between functions and operating the pipette effortless.
