Multi-functional Electronic Pipette (dPette+)

Multi-functional Electronic Pipette (dPette+)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. High-Precision Sample Preparation for PCR and qPCR Assays

• Primary Use: Provides a motor-driven, single-channel or 8-channel electronic pipette with high-performance stepper motor technology, designed for accurate and reproducible liquid handling in molecular diagnostic workflows such as PCR, qPCR, and sequencing library preparation.

• How it helps: For the molecular biologist and clinical laboratory scientist, the dPette+ eliminates manual pipetting variability caused by hand tremors or inconsistent technique. The stepper motor ensures precise volume delivery across all channels (systematic error ≤ ±1.0%, random error ≤ 0.8%), which is critical for the reproducibility of diagnostic amplification assays. For the patient, this precision translates directly to reliable PCR and qPCR results, reducing the risk of false negatives or inconclusive findings that would delay diagnosis and treatment.

2. Multi-Functional Modes for Workflow Efficiency

• Primary Use: Features four programmable operating modes – Pipetting, Mixing, Continuous Distribution (Stepper), and Dilution – allowing users to perform complex liquid handling protocols with a single instrument.

• How it helps: For the clinical laboratory scientist and research technician, the Stepper mode enables sequential dispensing of the same volume into multiple tubes or wells, while the Dilution mode automates serial dilution preparation. This reduces manual steps, minimizes calculation errors, and significantly improves throughput. Comparative studies have shown that using an electronic pipette to fill a 96-well plate can reduce the time from 7.5 minutes to less than 3 minutes – a 60% increase in efficiency. For the patient, faster sample processing reduces turnaround time for diagnostic test results, enabling earlier clinical intervention.

3. Adjustable Speed for Versatile Liquid Handling

• Primary Use: Allows independent adjustment of aspiration and dispensing speeds across multiple levels 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. Ergonomic Design to Reduce Operator Fatigue

• Primary Use: Features a lightweight (approximately 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 laboratories where thousands of pipetting actions are performed daily. The lower section can rotate 360°, accommodating both right-handed and left-handed users. For the patient, a comfortable and focused technician is better able to maintain precision and accuracy, supporting a higher standard of patient care.

5. 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 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 speed settings, with all critical parameters displayed clearly on the screen. For the patient, this user-friendly design ensures consistent and reliable sample preparation across different operators, directly contributing to the accuracy of their diagnostic tests.

6. Rechargeable Battery and USB Connectivity for Continuous Operation

• Primary Use: Features a built-in lithium-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 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.

SECONDARY & SUPPORTIVE USES

1. ELISA and Immunoassay Plate Filling: Used for precise dispensing of reagents, wash buffers, and substrates across 96-well microplates, ensuring consistent well-to-well reproducibility.

2. Next-Generation Sequencing (NGS) Library Preparation: Accurately transfers adapters, indexes, and master mixes for NGS workflows, where microliter precision is critical for sequencing success.

3. Cell Culture and Media Exchange: Suitable for adding reagents, seeding cells into multi-well plates, and aspirating culture media in biological research.

4. Toxicology and Drug Screening: Prepares calibration curves and dispenses compounds for high-throughput screening assays.

5. Quality Control (QC) Sample Preparation: Used in pharmaceutical QC laboratories for the precise preparation of standards, controls, and dissolution media.

6. Serial Dilution and Standard Curve Preparation: The Dilution mode automates the preparation of standard curves for quantitative assays, ensuring accurate concentration gradients.

7. Protein and Enzyme Assays: Dispenses reagents for enzyme-linked immunosorbent assays (ELISA), Bradford assays, and other protein quantification methods.

8. Microbiology and Antimicrobial Susceptibility Testing: Used for inoculating multi-well plates with bacterial cultures for MIC testing.

9. Food and Beverage Quality Testing: Prepares standards and extracts for food safety testing in quality control laboratories.

10. Environmental Testing: Used for preparing reagents for water and soil sample analysis in environmental monitoring laboratories.

11. Biobanking and Sample Aliquoting: Facilitates the rapid splitting of large-volume biological samples (plasma, urine, serum) into multiple replicate tubes or plates for long-term storage.

12. Flow Cytometry Sample Preparation: Dispenses antibodies and staining solutions for cell surface and intracellular staining protocols.

13. Veterinary Diagnostic Testing: Supports reagent preparation for assays used in animal health testing and infectious disease diagnosis.
