Compared to other handheld pipettors I’ve used, like the Eppendorf Easypet 3 and the Sartorius Tacta, the pipetus-junior stood out for its simplicity. While the Eppendorf and Sartorius offered more advanced features, they also came with a higher price tag and increased complexity. I opted for the Hirschmann model because it offered a balance of performance and affordability, perfect for my specific needs.
My first impression was one of cautious optimism. I was eager to put the pipetus-junior through its paces and see if it could live up to its promise of reliable performance. It seemed well-built, but the true test would be in the laboratory.
Real-World Testing: Putting Hirschmann pipetus-standard and pipetus-junior Pipettors, Hirschmann 9902000 pipetus-junior to the Test
First Use Experience
I first tested the pipetus-junior in a mobile water quality testing lab, focusing on applications requiring precise dispensing of standards for calibration. Conditions were varied, ranging from temperature fluctuations to potential exposure to moisture. I also tested in more controlled laboratory environments.
The pipetus-junior performed admirably under different temperature and humidity conditions. The single-button operation, while simple, provided surprisingly good control over aspiration and dispensing. There was a slight learning curve to mastering the valve system, but after a few practice runs, I was able to achieve consistent and accurate results.
One initial surprise was the relatively strong aspiration power for such a compact device. This allowed for quick and efficient pipetting, reducing the overall time spent on sample preparation. No immediate issues arose after the first use, and the pipettor felt comfortable and balanced in my hand.
Extended Use & Reliability
After several weeks of consistent use in a variety of analytical chemistry procedures, the Hirschmann 9902000 pipetus-junior has proven to be a reliable workhorse. I have found it to be crucial in many quality control and assurance tests in my lab.
Despite frequent handling and exposure to various chemicals, the pipetus-junior shows no signs of significant wear and tear. The plastic construction is resistant to staining and corrosion, and the internal components continue to function smoothly. The simple design makes cleaning and maintenance straightforward, requiring only occasional wiping with a damp cloth and replacement of the PTFE filter.
Compared to previous manual pipettes I’ve used, the pipetus-junior offers a noticeable improvement in terms of ergonomics and efficiency. The reduced hand strain and faster pipetting speeds have significantly improved my overall productivity. It has exceeded my expectations in terms of reliability and ease of use.
