Electronic Bottle-Top Dispenser (dFlow)

Electronic Bottle-Top Dispenser (dFlow) 

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Precision Dispensing of Clinical Laboratory Reagents

• Primary Use: Provides a motor-controlled electronic bottle-top dispenser with a volume range of 0.1-99.9mL, 16 adjustable speed levels, and a TFT display module, designed for accurate, fatigue-free dispensing of reagents, buffers, and chemical solutions directly from laboratory reagent bottles .

• How it helps: For the clinical laboratory scientist and medical technologist, the dFlow electronic dispenser eliminates manual pipetting fatigue by using a high-quality stepper motor that provides smooth, consistent dispensing with precision accuracy (10mL: R=0.5%, CV=0.3%) . The external remote control panel allows operation without manual disturbance, reducing the risk of repetitive strain injury . For the patient, precise reagent dispensing ensures that diagnostic test results are accurate and reproducible, reducing the risk of analytical errors that could lead to misdiagnosis or incorrect treatment decisions.

2. Two Operating Modes for Versatile Laboratory Workflows

• Primary Use: Features two operation modes – dispenser mode (single-volume dispensing) and stepper mode (continuous multi-volume dispensing) – allowing users to select the appropriate mode for different laboratory applications .

• How it helps: For the clinical laboratory scientist and research technician, dispenser mode is ideal for routine aliquot preparation where consistent single volumes are required, while stepper mode allows programming of multiple dispenses of the same volume sequentially, significantly improving workflow efficiency for high-throughput tasks . The TFT display provides clear visualization of volume settings and mode selection . For the patient, efficient laboratory workflows reduce turnaround times for diagnostic test results, enabling earlier clinical intervention.

3. Recirculation Feature to Minimize Reagent Waste

• Primary Use: Incorporates a reagent recovery feature (recirculation mode) that allows unused reagent to be returned to the bottle, minimizing costly reagent waste and reducing environmental impact .

• How it helps: For the laboratory manager and quality control officer, the recirculation feature allows priming of the dispensing tube without discarding expensive reagents into waste containers—particularly valuable for costly diagnostic reagents, antibodies, and pharmaceutical preparations. For the patient, efficient reagent use helps control laboratory operating costs, which can contribute to more affordable diagnostic testing.

4. Adjustable Aspiration and Dispensing Speed

• Primary Use: Allows independent adjustment of aspiration and dispensing speeds across 16 levels, enabling optimization for different liquid viscosities and volumes .

• How it helps: For the clinical laboratory scientist handling diverse reagent types, the variable speed control accommodates both low-viscosity liquids (e.g., water-based buffers) and high-viscosity liquids (e.g., glycerol, protein solutions, concentrated reagents). This prevents issues such as splashing, foaming, or incomplete aspiration that could affect volume accuracy. For the patient, proper handling of diagnostic reagents ensures that test results are not compromised by pre-analytical variables.

5. Stepper Motor for Smooth, Accurate Dispensing

• Primary Use: Utilizes a high-quality stepper motor drive system that provides smooth, vibration-free operation and precise volume control with a resolution of 100μL .

• How it helps: For the clinical laboratory scientist, the stepper motor eliminates the variability associated with manual pipetting, ensuring consistent volume delivery across hundreds of dispenses. The motor-driven operation reduces physical fatigue during repetitive dispensing tasks. For the patient, consistent volume accuracy ensures that diagnostic test results are reliable and reproducible, supporting accurate clinical decision-making.
