Eppendorf Reference 500µL Pipette: Precision, Ergonomics, and Reliability in One

The Eppendorf Reference 500µL pipette is a leading choice in laboratories worldwide, recognized for its superior accuracy, ergonomic design, and long-lasting durability. As part of the Reference Series, this pipette embodies the commitment to quality and precision that Eppendorf is known for. Ideal for a wide range of scientific applications, the Reference 500µL combines innovative design features with rigorous quality standards to provide reliable performance in any laboratory setting.

The Eppendorf Reference 500µL is a piston-stroke pipette that employs the air-cushion principle. This method relies on a cushion of air between the piston and the liquid, which minimizes contact with the sample, thus reducing the risk of contamination and ensuring high levels of precision in liquid handling. The air-cushion system makes it particularly suitable for working with aqueous solutions, offering consistent accuracy across repeated measurements.

The pipette's multi-functional control button simplifies laboratory workflows by offering versatile operation with different control depths. Depending on how far the button is pressed, the pipette can execute various functions, making it easy to aspirate, dispense, and eject tips with a single control. This design reduces hand strain, enhances workflow efficiency, and supports a variety of techniques in pipetting procedures, from routine tasks to more complex assays.

The name "Reference" reflects the pipette's extraordinary precision and accuracy. Each pipette in the Reference Series, including the 500µL model, undergoes rigorous testing according to ISO 8655 standards for piston-stroke pipettes with an air cushion. With a systematic approach to testing—employing degassed, bidistilled water at 20°C to 25°C—Eppendorf guarantees that each pipette meets or exceeds the expected performance levels for accuracy and precision.

To maintain accuracy, adjustments can be made to account for environmental factors such as altitude and air pressure. When used at high altitudes, the air cushion may be affected due to changes in ambient air pressure. The Reference 500µL can be recalibrated to accommodate these variations, ensuring that its performance remains consistent even in challenging environments.

Long pipetting sessions can lead to user fatigue, which is why the Reference 500µL features an ergonomic design that minimizes hand strain. The pipette's lightweight construction, combined with a smooth operating mechanism, supports prolonged use without compromising comfort. 

The Reference Series includes both fixed-volume pipettes, like the Reference 500µL, and adjustable-volume pipettes. This flexibility allows users to choose the model that best suits their needs. While the fixed-volume model is ideal for standardized assays requiring precise, repeatable measurements, adjustable models offer the flexibility to handle a range of volumes with a single instrument, making the series versatile for various applications.

Constructed from durable materials, the Eppendorf Reference 500µL is built to withstand the rigors of everyday laboratory use. Its robust design ensures a long service life, making it a cost-effective choice for laboratories that demand reliable equipment. The pipette is easy to maintain, with readily available accessories and spare parts that further extend its usability.
