Its primary volume range is 50-200 µl, making it suitable for a wide array of common laboratory tasks. The instrument boasts a unique multi-channel head with four distinct operational positions, each catering to different dispensing needs.

• Channel 1: One-Shot Capability: This channel is dedicated to single, precise aspirate and dispense actions. It’s ideal for applications where a single, accurate volume transfer is required without any deviation.
• Channel 2: Dual Independent Speeds: This position offers two adjustable speeds for dispensing. This feature is invaluable when dealing with different liquid viscosities or when the experiment demands a controlled, gradual release of a reagent.
• Channel 3: ‘Off’ Position with Dual Stowage & Adjustable Dead-Man Height: This unique channel includes an ‘off’ position for safety or when not in use, dual stowage options, and an adjustable “dead-man” height. The dead-man feature likely refers to a mechanism that requires continuous user input to maintain operation, preventing accidental discharges and offering fine control.
• Channel 4: Three Silicon Valves with “Choking” Capability: This position utilizes three silicon valves that can be adjusted to “choke” or restrict airflow. This allows for very precise control over air displacement, useful for applications like gas transfer or fine-tuning liquid aspiration.

The power switch is ergonomically placed on the side of the housing, easily accessible for quick activation and deactivation. The handpiece construction is designed to maintain a comfortable and familiar feel, even under varying temperature and humidity conditions, which is crucial for extended pipetting sessions in dynamic lab environments.

Performance & Functionality

The core function of the Wheaton Pipettor 50/200ul Xs 826 Cs2 W810309-TXS is precise liquid handling, and in this regard, it excels.
