Product Description
LTM20I Laboratory Ultra-Pure Water System
Dual-Stage RO Filtration for Precision Water Quality
Product Overview
The LTM20I is a high-performance water purification system engineered for laboratory, clinical, and research applications. Featuring dual-stage reverse osmosis (RO) technology, intelligent monitoring, and CE certification, it delivers consistent pure and ultra-pure water that meets strict international standards.
Key Features▶ 7-Inch Touch Human-Machine Interface with Dual Water Intake Modes
A design with both mechanical and touch-based water intake methods for flexible operation.
Real-time monitoring of RO conductivity, UP resistivity, and water flow.
Stores water intake records, water quality data, and equipment alarms for traceability.
▶ Advanced Dual-Stage RO Filtration
Dual-stage membrane system: First-stage recovery >30%, second-stage reuse for higher efficiency.
Proprietary RO membrane with ≥99% desalination rate, anti-pollution coating, and long service life.
Terminal 0.22μm bacterial filter ensures particle count
▶ Sterile Water Storage & Optional Upgrades
Mirror-finish stainless steel sterile tank (15L capacity) with built-in UV sterilizer (microbial count<0.1CFU/ml).
Optional features:
185/254nm dual-wavelength UV for TOC reduction (≤2ppb under specific conditions).
Leak detection alarm for enhanced safety.
▶ Smart & Customizable Operation
Targeted water intake by quality: Set target resistivity (≥18.2MΩ•cm) for automatic stop when reaching the standard.
Quantitative water intake: Preset volume options + custom input for personalized usage.
Automatic RO membrane flushing and UV sterilizer cycle cleaning.
▶ Compact & Reliable Design
Split-type structure: Main unit (337×450×628mm) fits on lab benches; tank (200×360×482mm) stores in cabinets.
Disposable consumables for tool-free replacement, minimizing downtime.
High-quality pipe fittings ensure leak-free operation and long-term stability.
