Breaking Down the Features of **Wheaton Pipettor 0.1-2ul Xs 826 Cs1 W810300-XS**

Specifications

The Wheaton Pipettor 0.1-2ul Xs 826 Cs1 W810300-XS is designed for ultra-micro volume transfers, covering a range of 0.1 to 2 µL. This specification is critical for applications requiring the highest level of precision at these low volumes, such as in PCR reaction setup, micro-injection, or precise reagent addition in cell-based assays. The Pipettor is identified by the supplier number W810300-XS and catalog number 89186-142, distinguishing it within Wheaton’s product line.

The product’s description highlights several key design elements that contribute to its performance. The smooth bore is crucial for reducing liquid retention, ensuring that the full dispensed volume is delivered. The negative-degree hemispherical sealing surface is an innovative feature designed to prevent retention and facilitate easier tip replacement, a common frustration with other pipettors.

Furthermore, the “plug metering tip” with its graduations at the end of the plunger offers an additional visual cue for fine-tuning volume settings, enhancing user confidence. The “power-down safety feature” is an interesting addition, suggesting a mechanism to prevent accidental volume changes or ensure a stable setting, though its exact implementation is not detailed. This thoughtful engineering aims to provide excellent resolution and accuracy, crucial for reproducible scientific work.

Performance & Functionality

The core function of the Wheaton Pipettor 0.1-2ul Xs 826 Cs1 W810300-XS is its ability to accurately and precisely dispense volumes between 0.1 and 2 µL. In practice, this pipettor excels at its primary task. The aspiration and dispensing are remarkably smooth, with minimal splash-back or residual liquid clinging to the tip. This means that when you set it to dispense 0.5 µL, you are reliably delivering very close to that exact amount, which is vital for reproducible experiments.

Its greatest strength lies in its exceptional accuracy and precision at the lower end of its range (0.1-0.5 µL). Many pipettors struggle to maintain accuracy below 1 µL, but this model consistently delivers within tight tolerances. The early-stage frothing mentioned likely refers to its ability to handle solutions that might otherwise foam excessively, maintaining aspirational integrity.

The main weakness, or perhaps a characteristic to be aware of, is that operating at such low volumes inherently requires more care and practice than with larger pipettors. While the design minimizes user error, external factors like temperature changes or rapid movements can still affect results. Its performance meets, and in many cases exceeds, the expectations for such a specialized, high-precision instrument.
