HHitech Master Touch Series Ultra-Pure Water System

Overview

The HHitech Master Touch Series Ultra-Pure Water System is a modular, GMP-aligned laboratory water purification platform engineered for consistent production of Type I ultrapure water (ASTM D1193-20) and Type II pure water. It integrates multi-stage purification—pre-treatment (PP/KDF/AC), reverse osmosis (RO), dual-wavelength UV photooxidation (185 nm & 254 nm), ultrafiltration (UF), and mixed-bed deionization (DI)—to meet stringent requirements for molecular biology, cell culture, HPLC, LC-MS, and trace elemental analysis. The system employs a closed-loop recirculation architecture with programmable intermittent circulation to suppress microbial proliferation while minimizing energy consumption. All wetted materials—including NSF-certified tubing, quick-connect fittings, and PES membrane filters—are selected to limit extractables and maintain low TOC (<3 ppb) and endotoxin (<0.001 EU/mL) levels in final ultrapure output.

Key Features

• 5.0-inch full-color capacitive touchscreen with animated GUI navigation and real-time system diagnostics
• Comprehensive consumables lifecycle management: configurable service intervals, runtime tracking, and proactive replacement alerts for PP, KDF, AC, RO, DI, UP, UV, UF, and TF modules
• Integrated data logging: one-year continuous recording via internal memory; exportable via USB or SD card in CSV format compliant with GLP audit trails
• Modular pre-treatment unit with tool-free, push-fit connections and field-replaceable 5 µm PP, KDF composite, and coconut-shell activated carbon cartridges
• Four-in-one detachable ultra-purification column assembly using Dow Chemical nuclear-grade ion exchange resins
• Automated RO membrane antiscalant flush cycle with user-defined frequency and duration; manual override available
• Dual-level password protection (factory + user) for system configuration, time/date settings, standby/sleep timers (0–60 min), and scheduled shutdown (0–24 h)
• Full-system sanitization protocols: loop circulation, point-of-use disinfection, tank refilling, manual drain, and termination control
• NSF-certified fluid path components to minimize TOC leaching; all tubing and connectors validated per NSF/ANSI Standard 61

Sample Compatibility & Compliance

The Master Touch Series accepts municipal potable water (5–45 °C, 1.0–4.0 kgf/cm² inlet pressure) as feedstock. Final ultrapure water meets or exceeds ISO 3696:1987 Grade 1, CLSI EP28-A3c, and USP specifications. RO rejection rates exceed 97% for ions and >99% for organics >200 Da. Terminal filtration utilizes hydrophilic PES membranes (0.45 + 0.1 µm) certified for sterile-grade delivery. UF module (5,000 Da MWCO) removes pyrogens to <0.001 EU/mL—validated for IVF and primary cell culture applications. RNase/DNase levels are reduced to <1 pg/mL and <5 pg/mL respectively, supporting sensitive nucleic acid workflows.

Software & Data Management

Embedded firmware supports timestamped event logging—including water quality metrics (resistivity, TOC, temperature), flow volume per dispensing event, consumables usage history, and alarm chronology (e.g., low pressure, high TOC, UV lamp failure). Data export adheres to GLP principles: files include digital signatures, immutable timestamps, and no post-acquisition editing capability. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements for electronic records when deployed in regulated environments. Optional Ethernet/WiFi connectivity enables remote monitoring via secure HTTP(S) interface (not included by default).

Applications

This system serves high-sensitivity analytical and life science applications requiring reproducible water purity: preparation of HPLC mobile phases and standards; buffer formulation for electrophoresis and chromatography; reagent dilution in ELISA and PCR; media sterilization for mammalian and stem cell culture; cleaning of quartz cuvettes and optical components; and calibration of TOC analyzers. Its low endotoxin and nuclease specifications make it suitable for monoclonal antibody production, CRISPR-Cas9 editing, and organoid differentiation protocols.

FAQ

What is the maximum daily output capacity of the Master Touch Series?

Rated at 45 L/hour of ultrapure water (18.2 MΩ·cm @ 25 °C); actual yield varies with ambient temperature, inlet water quality, and consumables condition.

Can the system be integrated with external storage tanks?

Yes—it supports both pressurized air-bladder tanks and atmospheric-level float-switch-controlled reservoirs; optional level sensors and pump controllers are available.

Is UV intensity monitored in real time?

The 185/254 nm UV lamps include integrated radiometric sensors that log irradiance decay and trigger maintenance alerts prior to performance degradation.

How often must the RO membrane be replaced?

Under typical municipal feedwater conditions and with scheduled antiscalant flushing, RO membrane service life exceeds 24 months; replacement interval is tracked automatically based on cumulative runtime and pressure differential.

Does the system support IQ/OQ documentation packages?

Factory-issued Installation Qualification (IQ) and Operational Qualification (OQ) templates are provided; site-specific Performance Qualification (PQ) must be conducted per local SOPs and regulatory expectations.
