Yarong SZ-97 Quartz Glass Distillation Apparatus

Overview

The Yarong SZ-97 Quartz Glass Distillation Apparatus is a benchtop, single-stage distillation system engineered for the production of high-purity water in analytical, pharmaceutical, and clinical laboratory environments. It operates on the principle of thermal phase separation—where feed water is vaporized under controlled heating, and the resulting steam is condensed back to liquid phase in a metal-free pathway—ensuring elimination of metallic ion leaching, organic volatiles, and particulate carryover. Unlike stainless-steel or borosilicate glass systems, the SZ-97 employs fully fused quartz components for both the boiling flask and condenser column, offering superior resistance to alkali corrosion, UV transparency, and thermal shock stability up to 1100 °C. This architecture is critical for applications requiring ultrapure water (Type I per ISO 3696 and ASTM D1193), particularly where trace metal contamination must be minimized—such as ICP-MS sample preparation, cell culture media formulation, and reagent-grade solvent purification.

Key Features

• Quartz tube heating element with precise thermal regulation, delivering uniform heat distribution and eliminating hot-spot formation in the distillation chamber.
• Fully quartz-wetted path: no contact between distilled water vapor or condensate and stainless steel, copper, or nickel alloys—preventing transition metal contamination (e.g., Fe, Cu, Ni) at sub-pptr levels.
• Circulating water condensation system with adjustable flow rate and temperature feedback loop, ensuring consistent condensation efficiency across variable ambient conditions.
• Dual endpoint detection: integrated temperature controller monitors vapor-phase temperature rise (indicating dry-run risk), while a hermetically sealed reed-type water level sensor detects low reservoir level—both signals trigger relay-based power interruption within <1.2 seconds.
• Fail-safe relay protection circuit compliant with IEC 61000-4-5 surge immunity standards, rated for continuous operation at 220 VAC ±10%, 50 Hz.

Sample Compatibility & Compliance

The SZ-97 accepts deionized, tap, or pre-filtered feed water (conductivity ≤5 µS/cm recommended). It is not intended for direct seawater or high-TDS industrial wastewater without prior pretreatment. The apparatus meets structural and operational requirements referenced in ISO 3696:1987 (Water for Analytical Laboratory Use), USP “Water for Pharmaceutical Purposes”, and supports audit-ready documentation for GLP and GMP environments when paired with external logging devices. All quartz components are certified to ASTM F798–22 (Standard Specification for Fused Silica and Fused Quartz) and tested for hydrolytic resistance per ISO 719 Class HGB 1.

Software & Data Management

The SZ-97 is a standalone analog-controlled unit with no embedded microprocessor or digital interface. Temperature setpoint and water level thresholds are adjusted manually via front-panel potentiometers. For regulatory traceability, users may integrate third-party data loggers (e.g., Omega OM-DAQPRO-5300 or Testo 176 T4) to record heater voltage, condenser inlet/outlet temperatures, and cycle duration. The relay cut-off signal can be wired to external PLCs or SCADA systems for centralized alarm monitoring. While the device itself does not comply with FDA 21 CFR Part 11, its deterministic mechanical control logic and physical interlock design facilitate validation under Annex 11 (EU GMP) and ALCOA+ data integrity principles when used with qualified peripheral instrumentation.

Applications

• Production of Type I ultrapure water for trace elemental analysis (ICP-OES, ICP-MS, GF-AAS).
• Preparation of metal-free solvents and buffers for molecular biology workflows (e.g., CRISPR reagent synthesis, qPCR master mix preparation).
• Calibration standard dilution water in environmental testing laboratories accredited to ISO/IEC 17025.
• Pharmaceutical water-for-injection (WFI) backup generation in non-sterile compounding areas (per USP ).
• Teaching laboratories requiring demonstrable separation physics and contamination control principles.

FAQ

Is the SZ-97 suitable for continuous 24/7 operation?
Yes—when operated with stable feed water quality and maintained condenser flow (≥2 L/min), the unit supports unattended 16-hour cycles. Quartz longevity exceeds 5,000 operating hours under nominal load.
Can it be connected to a central cooling water supply?
Yes, provided inlet pressure remains between 0.2–0.6 bar and temperature stays below 25 °C; a pressure regulator and inline particulate filter (≤5 µm) are strongly recommended.
Does the apparatus include a built-in conductivity meter?
No—the SZ-97 delivers distilled output only; real-time purity verification requires external measurement using a calibrated TOC/conductivity analyzer (e.g., Mettler Toledo InPro 7250 or Hanna HI98308).
What maintenance intervals are recommended?
Quartz chamber inspection every 200 hours; condenser tube descaling with 5% citric acid solution every 500 hours; reed sensor functional test monthly.
Is CE or UL certification available for this model?
The SZ-97 complies with GB/T 14710–2009 (Chinese Environmental Adaptation Standard) and meets EMC requirements per GB 4824–2019. CE marking is not affixed, but technical documentation supports self-certification for EU lab use under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD).
