Specifications

The Wheaton Pipettor 50-1000ul 926xs Cs1 W870916 is a single-channel, positive displacement pipettor with a volume range of 50 to 1000 µL. Its unique design is centered around the “CSO method with CMO” (Cell Suspension Optimization with Cell Media Optimization), which leverages a specific air-driven mechanism. This system forces all air into the tip to push it through a slipper valve stem, facilitating accurate dispensing without aspiration or over-injection issues. The pipettor features a wide-mouth design for easy droplet delivery of various viscosities and includes an angled neck to improve handling of these fluids. Clear volume markings are present on the tip, and the inclusion of graduations in both millilitres and teaspoons offers versatility for easy volume calculations and dilutions. A key feature is the removable dropper stem, which can be easily cleaned with alcohol, ensuring prompt reuse. The device is CE marked, indicating compliance with European safety, health, and environmental protection standards.

Performance & Functionality

This pipettor excels at its primary function: accurately dispensing a defined volume of liquid, especially viscous ones. The positive displacement mechanism is the star here, ensuring that the full volume is delivered consistently, regardless of liquid properties. This is a significant advantage over air-displacement pipettors when dealing with solutions that might adhere to the tip or have high surface tension. The smooth, controlled dispensing achieved through the wide-mouth design minimizes splashing and tip burning, which is critical when working with sensitive cell suspensions or volatile reagents. It meets and often exceeds expectations for its specialized application; for general liquid handling, it might be overkill, but for its intended use, it performs exceptionally well.
