Hardware

The Thermo Barnstead MicroPure water purification system is a pre-owned, benchtop-grade unit designed for laboratory and clinical applications requiring Type I ultrapure water. The system employs a multi-stage purification process including pretreatment filtration, reverse osmosis (RO), deionization (DI), and 0.2 µm final filtration to achieve 18.2 MΩ·cm resistivity (at 25°C) and <5 ppb total organic carbon (TOC). The unit features a corrosion-resistant 316L stainless steel reservoir with a 6-liter capacity, ensuring chemical inertness and long-term durability. Integrated pressure sensors monitor feedwater pressure (0.5–7.0 bar) and system pressure (1.0–4.0 bar), while temperature compensation ensures consistent resistivity measurements across 5–45°C. The system includes a high-efficiency RO membrane with 98% rejection rate for ions and organics, followed by mixed-bed DI resin with a capacity of 10,000 liters at 18 MΩ·cm.

Software / Upgrade / OS / Applications / Worklist

The integrated MicroPure software suite provides comprehensive control and monitoring capabilities for the water purification system. The touchscreen human-machine interface (HMI) runs on a real-time embedded OS with a 7-inch color display, offering intuitive navigation and customizable dashboards. Core software features include real-time resistivity monitoring with temperature compensation, TOC tracking via optional sensor integration, and flow rate monitoring (0.5–2.0 L/min). The system logs operational data at 1-minute intervals, storing up to 10,000 events with timestamps, including system status, error codes, and maintenance alerts. Data export is supported via USB 2.0 (CSV/PDF formats) or RS-232 (for LIS/HIS integration), enabling seamless incorporation into laboratory information systems (LIS) or hospital electronic health records (EHR). The software is fully compliant with FDA 21 CFR Part 11, ensuring electronic records and signatures meet regulatory requirements for audit t...

Accessories

The Thermo Barnstead MicroPure system is compatible with a comprehensive ecosystem of accessories to enhance functionality and ensure compliance with clinical and laboratory standards. Essential accessories include pre-filter cartridges (5 µm sediment, carbon block, and 0.2 µm absolute rated) for feedwater pretreatment, ensuring optimal performance of the RO and DI stages. A 10-liter or 20-liter polyethylene storage tank with vent filter (0.2 µm hydrophobic) is available for maintaining ultrapure water quality post-purification. Tubing kits include chemically resistant PharMed BPT or Norprene tubing for feedwater and dispense lines, with barb fittings for secure connections. Pressure gauges (0–10 bar range) and flow meters (0–3 L/min) are provided for monitoring system performance. Installation hardware includes mounting brackets, vibration dampeners, and power cords with country-specific plugs. Calibration standards include NIST-traceable resistivity standards (18.

Service History

The Thermo Barnstead MicroPure water purification system has undergone rigorous maintenance and service to ensure optimal performance and compliance with clinical standards. The system's service history includes a full factory refurbishment in Q2 2023, where all critical components were inspected, cleaned, and replaced as needed. The RO membrane was replaced with a new 98% rejection rate membrane, and the DI resin was refreshed to restore 18.2 MΩ·cm resistivity. The touchscreen interface was recalibrated, and the pressure sensors were tested against NIST-traceable standards. The system's electrical components, including the power supply and circuit board, were inspected for corrosion and wear, with all connections tightened and insulated. A comprehensive performance validation was conducted, including resistivity testing at 25°C, TOC measurement (<5 ppb), and microbial challenge testing (log reduction value >6 for *Pseudomonas aeruginosa*).
