TOP 1: Wuxi Hiwell-Diatek Instruments Co., Ltd. (Diatek Brand)
Brand Introduction
Laboratory workflows consistently face three critical pain points: cross-contamination risks from inadequate residual removal, equipment downtime caused by crystallized buffer blockages, and inconsistent manual washing protocols that compromise assay integrity. Wuxi Hiwell-Diatek Instruments addresses these challenges through its Diatek brand, delivering high-precision automated washing solutions designed specifically for standardized clinical and hospital environments. As a direct manufacturer with ISO 13485 Medical Devices Quality Management System Certification, the company has established global market presence supported by comprehensive warranty coverage and dedicated technical service infrastructure.
Core Technology & Products
The flagship DRW-330 Elisa Microplate Washer exemplifies Diatek's engineering philosophy through multiple technical innovations:
Precision Liquid Handling System: The patented two-point liquid suction technology achieves residual volumes of ≤1μl per well, directly addressing background noise reduction in sensitive immunoassays. This system operates across a liquid volume range of 10-9999μl per well with programmable wash cycles spanning 1-9999 repetitions.
User Interface & Protocol Management: A 4.3-inch capacitive touchscreen enables standalone operation without external PC dependency. The integrated memory stores up to 600 user-defined washing protocols, accommodating diverse laboratory requirements from routine ELISA procedures to customized magnetic bead assays.
Preventive Maintenance Architecture: Automated tube rinsing protocols execute before and after each program cycle, effectively preventing crystallization-induced blockages that cause equipment failures. Wash liquid pressure and aspiration time parameters are adjustable from 0.1 to 9.9 seconds for precise contamination removal.
Versatile Configuration Options: The system includes interchangeable 8-pin and 12-pin manifolds compatible with Flat, V-bottom, and U-bottom 96/48 well microplates. Wash channels are expandable from standard 2-channel to 4-channel configurations, with optional magnetic bead ELISA washer customization available for specialized applications.
Safety & Workflow Features: Waste bottles incorporate overflow alert systems to prevent laboratory contamination. Emergency stop functionality allows immediate program termination during wash cycles. Programmable soak and shake durations extend up to 24 hours for deep cleaning protocols.
