Electronic Pipette (dPette)

Electronic Pipette (dPette)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Motor-Driven Precision for Diagnostic Assays

• Primary Use: Provides a motor-driven, digitally controlled single-channel electronic pipette that ensures high accuracy and repeatability for clinical diagnostic applications such as ELISA, PCR setup, and sample preparation.

• How it helps: For the clinical laboratory scientist and molecular biologist, the dPette’s high-performance stepper motor eliminates manual pipetting errors caused by hand tremors or inconsistent speed, delivering systematic error of ≤ ±1.0% and precision (CV) of ≤ 0.8%. For the patient, this precision translates directly to reliable and reproducible diagnostic results, reducing the risk of pre-analytical errors and the need for repeat testing.

2. Ergonomic Design to Reduce Repetitive Strain Injury (RSI)

• Primary Use: Features a lightweight (110 g) , streamlined, ergonomic design that combines the natural feel of a manual pipette with the effortless operation of an electronic system, significantly reducing hand fatigue during prolonged use.

• How it helps: For the laboratory technician and healthcare worker, the ergonomic grip and minimal operation force help mitigate the risk of Repetitive Strain Injury (RSI), which is common in high-throughput labs where thousands of pipetting actions are performed daily. This design allows for fatigue-free, comfortable operation even during extended tasks like filling an entire 96-well plate. For the patient and the clinician, a comfortable and well-rested technician is better able to maintain focus and precision, ultimately supporting a higher standard of patient care.

3. Adjustable Speed for Versatile Liquid Handling

• Primary Use: Allows users to independently adjust aspiration and dispensing speeds across multiple levels to accommodate a wide variety of liquid types and volumes, from viscous solutions to foaming reagents.

• How it helps: For the pharmaceutical QC chemist and research scientist, this feature provides critical versatility. For instance, slower speeds can be set to handle high-viscosity liquids like serum or glycerol, ensuring accurate aspiration and preventing air bubbles, while faster speeds can be used for standard low-viscosity buffers to improve workflow efficiency. For the patient, this flexibility ensures that even challenging sample types are processed correctly, maintaining the integrity of diagnostic results.

4. Intuitive User Interface for Error-Free Operation

• Primary Use: Equipped with a large LCD screen and dual rotary knobs, the interface replicates the familiar logic of a manual pipette, making it easy to set parameters and switch between functions 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 dual knobs allow seamless control over volume adjustment, mode selection, and function settings, with all critical parameters displayed clearly on the screen. For the patient, this user-friendly design helps ensure consistent and reliable sample preparation across different operators, directly contributing to the accuracy of their diagnostic tests.

5. Rechargeable Battery and USB Connectivity for Continuous Operation

• Primary Use: Features a built-in lithium-ion (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 pipette 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 the patient, this reduces the risk of process delays and ensures that laboratory equipment is always ready for use, supporting timely diagnostic workflows.

6. Multi-Functional Modes for High-Throughput Workflows

• Primary Use: The advanced dPette+ model adds multi-functional capabilities beyond standard pipetting, including Mixing, Stepper (sequential dispensing), and Dilution modes.

• How it helps: For the clinical researcher and high-throughput laboratory staff, these modes are designed to dramatically improve efficiency. For instance, the Stepper mode is ideal for preparing a series of dilutions across a row of tubes, while the Dilution mode streamlines complex protocol steps. According to validation data, using an electronic pipette to fill a 96-well plate can reduce the time from 7.5 minutes to less than 3 minutes, an efficiency increase of over 60%. For the patient, these efficiencies translate directly to faster turnaround times for diagnostic test results, enabling earlier clinical decision-making.

SECONDARY & SUPPORTIVE USES

1. Molecular Biology Setup (qPCR, PCR): Ideal for accurately dispensing master mixes, primers, and probes, ensuring consistency across thousands of reactions.

2. Immunoassay (ELISA) Processing: Suitable for sample and reagent addition in 96-well plate ELISA workflows, where reproducibility is critical.

3. Genotyping and Sequencing Library Prep: Employed in genomics workflows to prepare samples and reagents with high precision and parallelism.

4. Quality Control (QC) and Pharmaceutical Testing: Used for the precise preparation of standards, controls, and dissolution media in regulated QC laboratories.

5. Cell Culture and Media Exchange: Suitable for adding dosing reagents and aspirating cell culture media in biological research and production.

6. Toxicology and Drug Screening: Prepares calibration curves and dispenses extraction solvents for LC-MS/MS analysis.

7. Food and Beverage Quality Testing: Used in food safety labs for standard solution preparation and sample extraction.

8. Environmental Testing Laboratories: Ideal for preparing reagents for water and soil sample analysis protocols.

9. Educational and Academic Research: Serves as a versatile teaching tool for training students in accurate liquid handling techniques.

10. Veterinary Diagnostic Testing: Supports reagent preparation for assays used in animal health testing.
