I’ve used it for everything from preparing DNA amplification reactions to dispensing precise volumes of staining solutions for microscopy. Throughout this period, it has maintained its initial smooth operation and accuracy. There are absolutely no signs of wear and tear yet; the plastics feel robust, and the metal components show no corrosion or stiffness. Cleaning is straightforward; a quick wipe-down with an appropriate lab disinfectant and a flush with distilled water is all that’s needed. I’ve found that occasional recalibration, which is a simple process with this model, ensures its continued precision. Compared to some budget pipettors I’ve used in the past, which often become less accurate and harder to operate after only a few months, this Wheaton unit has proven to be a significant step up in terms of durability and consistent performance.

Breaking Down the Features of Wheaton Pipettor 0.5-10ul 926 Cs1 W870114

Specifications

The Wheaton Pipettor 0.5-10ul 926 Cs1 W870114 boasts a precise volume range of 0.5 to 10 µL, a critical specification for micro-volume work. Its design features a blow-type, positive displacement tip which is key to its accuracy, especially with low viscosity liquids. This technology ensures accurate dispensing by directly displacing the liquid with the tip, minimizing residual volumes. The 926 ul single channel designation refers to its standard single-channel design, suitable for most benchtop applications. It incorporates a double-stop mechanism for aspiration and dispensing, offering precise control and preventing over-travel. The construction utilizes a high-grade, polished stainless steel tip wire for the internal mechanism, contributing significantly to its accuracy and long-term durability.

The wide-range tip distribution is a notable feature, designed to ensure the desired volume is delivered without requiring excessive force. This is crucial for user comfort during repetitive tasks, reducing hand fatigue. The catalog number 89209-958 identifies this specific model within the broader Wheaton product line. As a PIPETTORS type instrument, its primary function is accurate liquid handling.
