Wheaton Pipettor 0.25-5ml 936 Cs=1set W870920-A Review

Let’s Dive into Wheaton Pipettor 0.25-5ml 936 Cs=1set W870920-A

The Wheaton Pipettor 0.25-5ml 936 Cs=1set W870920-A is presented as a precision instrument, designed for accurate liquid handling within a 0.25 to 5 ml range. Manufactured by Wheaton, a company with a long-standing reputation in laboratory equipment, this pipettor distinguishes itself through its all-stainless steel construction, a dual-tip design, and fine graduation markings. Its purpose, unlike my usual foray into outdoor gear, pivots toward laboratory precision, a world where accuracy and repeatability reign supreme.

My interest in the Wheaton Pipettor stemmed from a collaboration with a friend’s research lab, where they were experiencing issues with inconsistent manual pipetting, impacting their experimental results. They needed a reliable, durable tool to ensure accuracy, and this Wheaton model seemed to offer the precision and robustness they required. The promise of a stainless-steel barrel and unique tip-changing mechanism immediately piqued my interest, being reminiscent of the robust construction found in high-quality tactical tools.

Upon unboxing, the first thing that struck me was the pipettor’s solid feel. The stainless steel construction exudes quality, and the weight provides a reassuring sense of stability, a stark contrast to the flimsy plastic pipettes I’ve occasionally encountered. The design is simple, yet purposeful, and the graduation markings are clear and easily readable.

Compared to basic disposable pipettes or even some adjustable volume micropipettes, the Wheaton Pipettor aims for a different level of accuracy and durability. While adjustable micropipettes offer versatility in volume selection, they often require calibration and are prone to mechanical failure. The Wheaton Pipettor, with its fixed volume design and stainless steel construction, promises consistent performance and longevity. I selected this model because of its simple design and the reputation of Wheaton quality.

My first impression was one of cautious optimism. The build quality is undeniable, and the innovative tip-changing mechanism is intriguing.

Real-World Testing: Putting Wheaton Pipettor 0.25-5ml 936 Cs=1set W870920-A to the Test

First Use Experience

The testing ground for the Wheaton Pipettor was, as mentioned, my friend’s research laboratory, specifically in their buffer preparation and serial dilution processes. I observed their technicians using it, focusing on their initial learning curve and how it integrated into their workflow. The pipettor was used with various aqueous solutions, ranging from buffers to cell culture media.

The lab environment maintained a relatively consistent temperature and humidity, but pipetting accuracy would still be vital. The initial learning curve was surprisingly shallow. The technicians quickly grasped the technique required to use both the male luer slip and the passive tip options, appreciate this considering their wide range of lab experience.

One immediate observation was that changing the tip from male luer slip to passive was not quite as smooth as the description implies. While the “light touch” does indeed alter the tip, achieving a precise volume change often required a bit of finesse, and more practice.

Extended Use & Reliability

After several weeks of daily use, the Wheaton Pipettor continued to perform consistently. The stainless steel showed no signs of corrosion or degradation from the chemicals used, a testament to its material quality. Maintenance primarily involved rinsing the pipettor with distilled water and occasionally cleaning the tip with ethanol, a simple and straightforward process.

The pipettor has proved durable and reliable. Its stainless steel construction ensures that. It definitely outperformed the plastic disposable pipettes they were previously using. The consistent volume delivery has contributed to more reliable experimental results, validating the initial investment.

Breaking Down the Features of Wheaton Pipettor 0.25-5ml 936 Cs=1set W870920-A

Specifications

• Volume Range: 0.25-5ml. This range covers a significant portion of standard laboratory pipetting needs, making it versatile for various applications.
• Material: All Stainless Steel. The stainless steel barrel and tip provide exceptional durability, chemical resistance, and ease of cleaning, crucial for maintaining accuracy and preventing contamination.
• Graduation Markings: Double-Sided. These markings enable easy volume measurement from either side, enhancing usability for both right- and left-handed users.
• Tip Design: Changeable from Male Luer Slip to Passive Tip. This feature provides flexibility in dispensing liquids, allowing users to choose the tip that best suits their specific application.
• Filling Line: Removable. The removable filling line simplifies cleaning and maintenance, contributing to the pipettor’s overall longevity.
• Catalog number: 89210-012
• Type: PIPETTORS

These specifications are significant because they directly influence the pipettor’s accuracy, durability, and ease of use. The stainless steel construction ensures that the pipettor can withstand repeated use and exposure to harsh chemicals, while the changeable tip design enhances its versatility. The clear graduation markings and removable filling line contribute to precise volume measurement and easy maintenance.

Performance & Functionality

The Wheaton Pipettor 0.25-5ml 936 Cs=1set W870920-A excels in delivering consistent and accurate liquid volumes within its specified range. Its stainless steel construction minimizes the risk of contamination, ensuring reliable results. The strengths lie in its durability, chemical resistance, and relatively simple operation.

However, the tip-changing mechanism, while innovative, can require a bit of practice to master. Achieving precise volume adjustments using the passive tip requires a delicate touch, and the lack of a clear, definitive “click” or feedback can lead to inconsistencies if the user is not careful. Overall, the pipettor meets expectations for accuracy and reliability, especially when used by experienced technicians.

Design & Ergonomics

The Wheaton Pipettor’s design prioritizes functionality and durability over elaborate aesthetics. The stainless steel construction provides a solid and robust feel, inspiring confidence in its long-term reliability. The weight is balanced, and the overall ergonomics are comfortable for extended use.

The pipettor’s simple design makes it relatively user-friendly, although the tip-changing mechanism does present a slight learning curve. The clear graduation markings are a welcome feature, facilitating accurate volume measurement.

Durability & Maintenance

Given its all-stainless steel construction, the Wheaton Pipettor is expected to last for many years with proper care. The material is highly resistant to corrosion and chemical damage, ensuring its longevity. Maintenance is straightforward, involving simple cleaning procedures to prevent contamination.
