Let’s Dive into Eppendorf Pipette Res Plus Fixed 25ul 3121000058
The Eppendorf Pipette Res Plus Fixed 25ul 3121000058 is a single-channel, fixed-volume pipette designed for precision liquid handling. Manufactured by Eppendorf, this pipette boasts a spring-loaded tip cone and optimized piston, aiming for ultimate ergonomics, accuracy, and precision. Considering the critical nature of accurate measurements in research, I was eager to see if this pipette lived up to its promises, especially with its hefty price tag.
My lab needed a reliable and precise pipette for dispensing small volumes of reagents in our PCR setup. We were struggling with inconsistencies using our older, less ergonomic pipettes, leading to variations in our experimental results. The Eppendorf name is synonymous with quality in the lab equipment world, and the “Research Plus” line promised improved ergonomics and accuracy.
Unboxing the Eppendorf Pipette Res Plus Fixed 25ul 3121000058, I was immediately struck by its lightweight design and the feel of the materials. It seemed robust, yet comfortable to hold. The spring-loaded tip cone felt like a significant upgrade compared to our older pipettes, promising a more secure and consistent tip attachment.
We also considered the Gilson PIPETMAN Neo Fixed Volume Pipette and the BrandTech Transferpette S Fixed Volume Pipette. We opted for the Eppendorf due to its reputation for superior ergonomics and the spring-loaded tip cone feature, which neither of the other pipettes offered.
My initial impression was cautiously optimistic. The build quality seemed excellent, and the ergonomics felt noticeably better than our existing pipettes. I was excited to see how it performed in real-world lab conditions, but the price gave me pause; it needed to perform exceptionally well to justify the investment.
Real-World Testing: Putting Eppendorf Pipette Res Plus Fixed 25ul 3121000058 to the Test
First Use Experience
I first tested the Eppendorf Pipette Res Plus Fixed 25ul 3121000058 in our molecular biology lab, performing PCR reactions and dispensing enzyme solutions. The lab is climate-controlled, but temperature fluctuations can still occur, especially during busy periods. The pipette immediately felt more comfortable to use for extended periods.
The fixed volume made dispensing repetitive tasks quick and straightforward. The spring-loaded tip cone worked flawlessly, consistently ejecting tips with minimal force. There were no issues, and the Eppendorf performed as expected, giving me confidence in its accuracy.
