Putting the Hirschmann pipetus-standard and pipetus-junior Pipettors, Hirschmann 9905000 pipetus-standard to Work

The Hirschmann pipetus-standard and pipetus-junior Pipettors, Hirschmann 9905000 pipetus-standard are designed for precision liquid handling in laboratory settings. These pipettors offer solutions for both large and small volume applications, catering to diverse laboratory needs. Hirschmann aims to combine reliability and affordability in their liquid handling products.

My work in a high-throughput screening lab requires precise and efficient pipetting, especially with potentially hazardous substances. I needed a pipettor that offered both accuracy and safety, minimizing the risk of contamination and user exposure. The advertised feature of the pipetus-standard with its separate pump for handling toxic liquids caught my attention.

The packaging was straightforward and functional. Upon unboxing, the Hirschmann pipetus-standard felt robust and well-constructed. The handle had a comfortable ergonomic feel, which is crucial for extended use.

Compared to the Eppendorf Easypet 3 and the Brand accu-jet Pro, the Hirschmann pipetus-standard seemed to offer a more modular approach, especially with the external pump. The others felt more integrated but potentially more limiting for specific applications like working in a laminar flow hood. I chose the Hirschmann for its potential versatility in various lab settings.

My first impression was one of cautious optimism. It appeared to be a thoughtfully designed tool with the potential to improve our lab’s workflow, but I was eager to see how it performed under real-world conditions.

Real-World Testing: Putting Hirschmann pipetus-standard and pipetus-junior Pipettors, Hirschmann 9905000 pipetus-standard to the Test

First Use Experience

I initially tested the Hirschmann pipetus-standard in our chemical synthesis lab. We used it to accurately dispense solvents for reactions and for preparing dilutions of stock solutions. The separate pump allowed me to work inside a fume hood without worry of contaminating the lab environment with solvent vapors.

The pipetus-standard performed flawlessly under these conditions, providing smooth and consistent aspiration and dispensing. Getting accustomed to the controls took a few minutes, but the variable speed settings allowed for fine-tuned control. There were no leaks or unexpected issues during the initial testing.

Extended Use & Reliability

After several weeks of daily use, the Hirschmann pipetus-standard has proven to be a reliable workhorse. The ergonomic design has minimized hand fatigue during long pipetting sessions, a significant improvement over previous manual pipetting. The durable construction shows no signs of wear and tear.

Cleaning and maintenance are straightforward. The check valve and membrane filter are easily accessible and replaceable. Compared to our older, less sophisticated pipettors, the Hirschmann offers greater precision, increased safety, and improved user comfort.
