Dymind DF55 5-Part Auto Hematology Analyzer
The Dymind DF55 is a compact, economic 5-part hematology analyzer providing 27 parameters + 4 histograms at 60 tests/hour with 20 µL sample volume. Optimized for small hospitals and clinics, it integrates laser scatter + flow cytometry for WBC diff, impedance for RBC/PLT, cyanide-free HGB, independent BASO channel, and 10.4-inch touchscreen with 100,000-result storage and built-in printer. Supports venous, capillary, and pre-diluted modes for accurate, efficient blood diagnostics.
Description
5-Part Differentiation: Detailed White Blood Cell Subpopulation Analysis The Dymind DF55 employs laser scatter and flow cytometry with chemical dye to deliver true 5-part WBC differentiation, including neutrophils (NE# and NE%), eosinophils (EO# and EO%), basophils (BA# and BA%), monocytes (MO# and MO%), and lymphocytes (LY# and LY%). This advanced segmentation, enhanced by an independent basophil channel for superior accuracy, enables precise identification of subtle abnormalities like eosinophilia in allergies, basopenia in acute infections, or monocytosis in chronic inflammation, supporting comprehensive hematologic evaluation in oncology, immunology, and infectious disease management.
Parameters Measured: Measures 27 parameters (23 reportable), encompassing full CBC and diff: WBC, NE#, EO#, BA#, MO#, LY#, NE%, EO%, BA%, MO%, LY%, RBC, HGB (via cyanide-free spectrophotometry for environmental safety), HCT, MCV, MCH, MCHC, RDW-SD, RDW-CV, PLT, MPV, PDW, PCT, P-LCR, and P-LCC. Generates four histograms (WBC, BASO, RBC, PLT) and a 2D scattergram for intuitive visual analysis, with automated flags and alarms for atypical cells, blasts, or immature granulocytes, aiding in early detection of leukemias or reactive thrombocytosis.
Sample Requirements: Requires only 20 µL of sample, minimizing patient discomfort in routine or pediatric testing. Accommodates three modes—venous whole blood for standard labs, capillary whole blood (e.g., fingerstick for rapid screening), and pre-diluted for high-volume or specialized assays—ensuring adaptability without manual adjustments or additional equipment.
Throughput: Achieves up to 60 samples per hour with fully automated processing, ideal for mid-sized clinics or satellite labs managing 400–700 tests daily. The seamless sample-to-result pipeline, including auto-rinsing and no-clog design, supports uninterrupted operation during busy shifts, reducing TAT to under 60 seconds per sample.
Technology: Utilizes tri-angle laser scatter + flow cytometry + chemical dye for WBC differential, electrical impedance for RBC/PLT counting, and cyanide-free colorimetric method for HGB to eliminate toxic reagents. The independent optical BASO channel minimizes interference, while digital pulse processing and sheath flow enhance resolution for low-count samples. Dual-channel architecture and AI-assisted flagging deliver CVs <2% for key parameters, with built-in linearity checks up to 100 x 10^9/L for WBC, ensuring robust performance in diverse populations.
User Interface and Storage: Features a high-resolution 10.4-inch TFT touchscreen with graphical workflows and multilingual support (up to 10 languages, including English, Spanish, Russian, and Chinese) for intuitive, error-free operation. Stores up to 100,000 results with integrated patient data, histograms, scattergrams, and QC logs, searchable by ID or date. Built-in thermal printer outputs customizable templates, complemented by 4 USB ports, 1 LAN for HL7 LIS integration, and export options in PDF/CSV for seamless EMR connectivity and remote review.
Reagent System: Open system compatible with Dymind’s low-cost, high-stability reagents (e.g., DYM-Diff Lyse for 5-diff, DYM-Diluent), with dedicated positions for diluent, lyse, and cleaner to prevent carryover. Low reagent usage (up to 50% less than competitors) and automated two-level QC extend calibration to 48 hours, while wider dynamic ranges reduce dilutions, optimizing costs and simplifying supply chain for resource-limited settings.
Dimensions and Portability: Benchtop unit measures 260 × 385 × 435 mm (W × D × H) at 28 kg, designed for easy placement in compact labs or mobile units. Operates quietly (<55 dB) on AC 110–220V with low power (≤150 VA), tolerating 10–40°C ambient temperatures and 30–85% humidity for reliable deployment in varied global climates.
