Real-World Testing: Putting Wheaton Pipettor 10-200ul 926 Cs1 W870124 to the Test
First Use Experience
My initial testing of the Wheaton Pipettor 10-200ul 926 Cs1 W870124 involved preparing standards for quantitative analysis in our lab. This required repeatedly dispensing volumes in the 50-150ul range. The immediate difference from using standard pipettes was noticeable – the plunger action felt much more consistent and controlled.
I tested the pipettor’s performance under various environmental conditions. I performed trials at room temperature, in a cold room at 4°C, and even in a slightly humid environment to mimic potential real-world lab conditions. The positive displacement technology held up admirably, delivering consistent volumes regardless of temperature or humidity changes that can affect air displacement pipettes.
The ergonomic design of the grip made the Wheaton Pipettor comfortable to use even during extended pipetting sessions. The adjustable blowout feature was also a welcome addition, allowing for complete dispensing of viscous liquids and ensuring no sample was left behind. There was a slight learning curve in mastering the plunger speed for optimal accuracy, but after a few practice runs, I was achieving consistent and reliable results.
One pleasant surprise was the audible click mechanism at each volume increment; it provided clear feedback that the desired volume had been reached, minimizing the risk of accidental adjustments during use.
Extended Use & Reliability
After several weeks of consistent use, the Wheaton Pipettor 10-200ul 926 Cs1 W870124 has proven to be a reliable and durable tool. The build quality is excellent. There is no noticeable wear and tear despite daily handling and repeated use.
Cleaning and maintenance are straightforward. The autoclavable components allow for thorough sterilization, crucial in maintaining sample integrity and preventing cross-contamination. The few parts dissemble easily, meaning cleaning is not a chore.
The Wheaton Pipettor significantly outperforms any air displacement pipettes I’ve used in the past when handling viscous or volatile liquids. The consistency and accuracy of the dispensed volumes have reduced the variability in my experimental results, leading to more reliable data and fewer repeats.
Breaking Down the Features of Wheaton Pipettor 10-200ul 926 Cs1 W870124
Specifications
The Wheaton Pipettor 10-200ul 926 Cs1 W870124 is designed for precise liquid handling in the 10 to 200 microliter range. It uses positive displacement technology to ensure accurate and reproducible dispensing, unlike air displacement pipettes that can be affected by liquid viscosity and vapor pressure.
The pipettor is constructed from polypropylene (PP) and polytetrafluoroethylene (PTFE), making it chemically resistant and suitable for use with a wide range of solvents and reagents. The materials of construction make the pipettor steam autoclavable, allowing for sterilization. This helps maintain sterile conditions and prevent contamination.
The positive-displacement tip design with molded tip guides prevents needle blowouts, ensuring safe and reliable dispensing. The pilot and syringe are permanently attached and contain a positive-displacement check valve, preventing splattering and contamination of the sample.
The ergonomically designed grip and adjustable blowout reduce needle injury and promote user comfort during prolonged use. The enlarged safety cover has a bright red LED light to identify the presence of a leak, enhancing safety and alerting the user to potential issues. The blue light indicates the level of the liquid.
Performance & Functionality
The Wheaton Pipettor 10-200ul 926 Cs1 W870124 excels in delivering accurate and reproducible volumes, particularly with challenging liquids like viscous solutions or volatile solvents. The positive displacement design eliminates air gaps, providing consistent performance regardless of the liquid’s properties. The accuracy is unmatched compared to using standard air displacement pipettes.
The pipettor’s strengths lie in its accuracy, reliability, and safety features. The positive displacement technology ensures consistent volume delivery, while the LED leak detection system enhances safety.
