Electronic Pipettes

Electronic pipettes resemble mechanical pipettes in many ways. The main difference is that electronic pipettes are more versatile tools, thanks to electronic aspiration and dispensing and multiple pipetting modes. Also electronic pipettes help reduce human variance.

An electronic motor drives the piston up or down to aspirate or dispense, and when desired amount has been reached brake system precisely stops the piston at correct position. The operating buttons and display are used to program desired volumes and operating modes. Electronic pipettes have multiple pipetting modes to speed up work. However, it is important to note that there can be some differences between different models.

The main difference is with electronic pipettes the user does not move the piston to aspirate or dispense, or eject tips, but the pipette does it for the user with a help of a motor by click of a button.

They reduce human variance as they take care of aspiration and dispensing. Their multiple pipetting modes speed up work. Also electronic pipettes offer security features, like calibration reminders and password protection for saved programs.

Basic maintenance and calibration is very similar to mechanical pipettes. The lower part of electronic and mechanical pipette resemble each other. The main difference is that every now and then you also need to replace the battery.

Single-channel pipettes are great when you need to pipette to and from different kinds of tubes and vessels. Also, for large volume pipetting (1.2-10 ml), single-channel pipettes are the only choice. However, when you work with large number of samples in 96-well or 384-plates, the multichannel pipettes are a better option.

Volumetric pipettes: Volumetric pipettes are typically made of plastic or glass and have graduation marks. Their volumes generally range between 1mL - 100mL. Volumetric pipettes rely on users for measurement of volume and require a separate device for aspiration and dispensing - such as the Midi Plus pipette controller.

Mechanical / manual pipettes: A workhorse of most laboratories and widely used in various applications. Manual pipettes aspirate and dispense liquid with piston system driving air cushions. These pipettes always use disposable pipette tips. User is able to set volume and use a plunger to aspirate and dispense liquid.

Electronic pipette: The basic operating principle of electronic pipettes is the same as with mechanical, but all actions are handled by an electronic system inside. The user only has to press a button to start aspiration, liquid dispensing or tip ejection. Electronic pipettes typically reduce human variance, improving accuracy and reproducibility.

Automation pipettes: Automation pipettes are similar to electronic. The key difference is they are controlled by automation software and typically have mounting points for automation instead of handles for humans. 

Dispenser / positive displacement pipettes: Positive displacement pipettes rely on syringe-like consumables for aspiration and dispensing. Available in mechanical and electronic form.

An automatic pipette, also known as an electronic pipette, is a laboratory instrument used to measure and transfer precise volumes of liquid. These are widely used in various fields such as biology, chemistry, and pharmaceuticals, where precise liquid handling is crucial.

Some key features:

• Adjustable volume: Users can set the desired volume before starting to pipette.
• Programmable functions: Performing complex pipetting protocols, such as multi-dispensing or sequential pipetting steps.
• Consistency and Precision: Automatic pipettes offer high precision and consistency for pipetting, even minimizing operator variance.
• Ergonomic pipetting: Automatic pipettes require minimal thumb pressure to operate. Especially helpful for work which requires a lot of repetitive pipetting.
