Electronic Single-Channel Pipettor (dPette-S)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Precision Liquid Handling for Clinical Chemistry and Immunoassays

• Primary Use: Provides a motor-driven, single-channel electronic pipettor designed for accurate and reproducible liquid handling in clinical diagnostic workflows such as reagent preparation, sample transfer, and assay execution .

• How it helps: For the clinical laboratory scientist and medical technologist, the dPette-S eliminates manual pipetting variability by using a high-precision stepper motor with built-in error correction . This ensures reproducible results for critical diagnostic tests like ELISA, clinical chemistry panels, and immunoassays . For the patient, this precision reduces the risk of erroneous results due to volumetric inconsistencies, supporting accurate diagnosis and appropriate treatment decisions.

2. Motor-Driven Operation to Reduce Repetitive Strain Injury (RSI)

• Primary Use: Features a lightweight (approximately 110g), ergonomic design with motor-driven, digital control, reducing the manual effort required for repetitive pipetting tasks .

• How it helps: For the laboratory technician and healthcare worker, the streamlined body and effortless electronic operation help mitigate the risk of repetitive strain injury commonly associated with prolonged manual pipetting. The intuitive dual rotary knob interface allows seamless control without awkward hand positioning . For the patient, a comfortable and well-rested technician is better able to maintain precision and focus, supporting a higher standard of patient care.

3. Adjustable Speed for Optimal Liquid Handling

• Primary Use: Allows independent adjustment of aspiration and dispensing speeds to accommodate a wide variety of liquid types, from low-viscosity buffers to high-viscosity solutions such as serum, glycerol, or protein solutions .

• How it helps: For the pharmaceutical QC chemist and research scientist, slower speeds can be set to handle viscous liquids, preventing air bubbles and ensuring accurate volume aspiration, while faster speeds can be used for standard buffers to improve workflow efficiency. For the patient, this versatility ensures that even challenging sample types are processed correctly, maintaining the integrity of diagnostic results across a broad range of clinical specimens.

4. Intuitive User Interface for Error-Free Operation

• Primary Use: Equipped with a large LCD screen and dual rotary knobs that replicate the familiar logic of a manual pipette, making it easy to set parameters and access the mixing function without navigating complex menus .

• How it helps: For the busy laboratory professional, the intuitive interface minimizes the learning curve and reduces the potential for operational errors. The large screen displays critical parameters at a glance, ensuring consistent technique across different operators . For the patient, this user-friendly design contributes to the overall reproducibility of diagnostic assays, reducing variability in test results .

5. Rechargeable Battery and USB Connectivity for Continuous Operation

• Primary Use: Features a built-in rechargeable Li-ion battery that supports extended operation and can be conveniently recharged via a desktop stand or a USB cable, ensuring minimal downtime .

• How it helps: For the laboratory manager, the dual charging options and long battery life provide operational flexibility, allowing the pipettor to be used continuously throughout the day without interruption. The USB connectivity also facilitates automatic calibration via a computer, eliminating the need to send the device off-site for service . For the patient, this reduces the risk of process delays and ensures that laboratory equipment is always ready for use, supporting timely diagnostic workflows.

6. Convenient Mixing Function and Autoclavable Components

• Primary Use: Provides a mixing function that allows users to homogenize samples or reagents directly in the pipette tip, eliminating the need for separate mixing steps . The lower portion of the pipette is also autoclavable for aseptic applications .

• How it helps: For the molecular biologist and cell culture specialist, the mixing function streamlines protocol steps such as resuspending cell pellets or mixing PCR components. The autoclavable tip cone assembly ensures sterility, preventing cross-contamination between cell culture lines or sensitive DNA/RNA samples . For the patient, these features minimize the risk of sample contamination and simplify complex laboratory protocols, leading to more reliable test results.
