Portescap’s 20DAM Linear Stepper Actuator: A Perfect Fit for Electronic Pipettes

In the fast-paced world of laboratory research and diagnostics, precision, reliability, and efficiency are paramount. One critical tool that embodies these qualities is the electronic pipette, an essential instrument for accurately measuring and transferring small volumes of liquid. A key component driving the performance of these pipettes is the linear actuator, and Portescap’s 20DAM linear stepper actuator stands out as an ideal choice. Here’s why:

Precision and Accuracy
Electronic pipettes demand high precision to ensure accurate liquid handling. Portescap’s 20DAM is designed with a linear resolution of down to 25.4 µm per step, that allows for fine control over movement. This high resolution ensures that the pipette can deliver precise volumes, which is crucial for experiments requiring exact measurements. The stepper motor's ability to move in discrete steps allows for repeatable positioning, minimizing errors and enhancing reliability.

Compact and Lightweight Design
Laboratory environments require repetitive tasks to be completed throughout the day, highlighting the need for optimum ergonomics in their devices. Portescap’s 20DAM’s compact size and lightweight construction make it an excellent fit for electronic pipettes. Its small diameter of 20mm allows for a slim and therefore ergonomic pipette design, ideal for users of all hand sizes. A low weight of 25g helps in reducing user fatigue during prolonged use over several hours. The captive design allows designers to utilize direct linear motion for fluid dispensing, further reducing the overall size of the pipette.

High Efficiency and Low Power Consumption
Efficiency and power consumption are critical factors in the design of battery powered electronic pipettes. This efficiency is vital for laboratory settings where electronic pipettes are used extensively throughout the day. The high linear force of the 20DAM requires lower energy consumption for dispensing and aspirating liquids, translating to longer battery life and enabling operation throughout the day.

Customizability and Versatility
The diverse applications in modern laboratories require versatile equipment that can be tailored to specific needs. This linear stepper actuator offers a range of customizable options including windings options for various battery sources, flange removal for a streamlined design and electrical connections to facilitate easy installation. These options allow manufacturers to tailor the 20DAM to the exact requirements of their design.

Conclusion
The 20DAM linear stepper actuator is a solid choice for electronic pipettes in labs. It’s precise, easy to handle, and energy-efficient, making daily tasks smoother for researchers.
