Yarong SZ-93 Quartz Glass Distillation Apparatus

Overview

The Yarong SZ-93 Quartz Glass Distillation Apparatus is a benchtop laboratory distillation system engineered for the production of high-purity water in analytical, pharmaceutical, and quality control laboratories. It operates on the principle of thermal phase separation—boiling feed water to generate steam, followed by controlled condensation into liquid phase—ensuring removal of non-volatile contaminants including ions, organic particulates, and microbial residues. Unlike stainless-steel or borosilicate-only systems, the SZ-93 integrates fused quartz heating elements and quartz-lined vapor pathways, minimizing trace metal leaching and eliminating metallic ion contamination during distillation. Its closed-loop condensation circuit ensures that distilled water never contacts copper, nickel, or other conductive metals commonly found in conventional condensers—making it suitable for applications requiring ultrapure water specifications per ASTM D1193 Type I or ISO 3696 Grade 1.

Key Features

• Quartz tube heating element with uniform thermal distribution and rapid response time, enabling stable boiling without localized superheating or quartz fracture risk.
• Metal-free condensation pathway: Entire condenser assembly—including cooling jacket, condensing coil, and collection tubing—is constructed from fused quartz and fluoropolymer-lined components, preventing ion exchange and maintaining low conductivity (< 0.1 µS/cm typical after stabilization).
• Dual endpoint detection system: Combines a calibrated platinum resistance temperature sensor (±0.3 °C accuracy) with a hermetically sealed reed switch water level sensor to monitor both vapor temperature rise and reservoir depletion, triggering automatic power cutoff before dry-run conditions occur.
• Integrated relay-based safety circuit with thermal cut-off and overcurrent protection, compliant with IEC 61010-1 requirements for laboratory electrical equipment.
• Modular frame design using 304 stainless steel structural supports and chemical-resistant engineering plastics (e.g., PTFE-reinforced polypropylene), facilitating cleaning, maintenance, and long-term corrosion resistance in humid environments.

Sample Compatibility & Compliance

The SZ-93 accepts deionized, tap, or pretreated municipal water as feedstock. It is not intended for direct distillation of organic solvents or high-salinity brines. The apparatus meets essential mechanical and electrical safety standards applicable to Class II laboratory appliances under GB/T 22264.1–2008 (Chinese national standard aligned with IEC 61010). While not certified to UL or CE for export markets, its architecture supports validation protocols required under FDA 21 CFR Part 11 (when paired with compliant data logging software) and GLP/GMP documentation frameworks. Routine operation aligns with ISO/IEC 17025 clause 5.5.2 regarding equipment suitability for intended use.

Software & Data Management

The SZ-93 operates as a standalone analog-electronic unit without embedded microprocessor control or digital interface. Temperature setpoint and power activation are managed via front-panel potentiometer and toggle switch; no firmware, USB port, or network connectivity is present. For regulatory traceability, users may integrate external calibrated thermocouple loggers (e.g., Omega OM-DAQPRO-5300) connected to the sensor output terminals. All endpoint events—power interruption, temperature excursion, and water level trigger—are recorded via mechanical relay state changes, enabling integration with programmable logic controllers (PLCs) or building management systems (BMS) for audit-ready event logging.

Applications

• Preparation of reagent-grade water for HPLC mobile phase preparation, atomic absorption spectroscopy (AAS), and inductively coupled plasma mass spectrometry (ICP-MS).
• Generation of calibration blanks and matrix-matched standards in environmental testing laboratories accredited to ISO/IEC 17025.
• Water purification for cell culture media formulation where trace metal interference must be excluded.
• Supporting USP “Water for Pharmaceutical Purposes” requirements when used as part of a multi-stage purification train (e.g., preceding ultrafiltration or UV oxidation).
• Routine QC water production in food safety labs performing AOAC 971.27 or ISO 5725-2 traceability workflows.

FAQ

Is the SZ-93 suitable for continuous unattended operation?
Yes—when fed from a pressurized reservoir with stable inlet pressure (0.1–0.3 MPa), and when ambient room temperature remains between 15–30 °C to ensure consistent condenser efficiency.
Can the unit be validated for GMP compliance?
It supports IQ/OQ protocols through third-party calibration of temperature sensors and relay timing verification; however, formal PQ requires integration with documented water quality testing (e.g., TOC, conductivity, bacterial endotoxin assays).
What maintenance intervals are recommended?
Quartz components require quarterly visual inspection for haze or microcracks; condenser coils should be flushed monthly with 5% citric acid solution to prevent scale accumulation; relay contacts should be verified annually for contact resistance (< 50 mΩ).
Does the system include a built-in water quality monitor?
No—conductivity or TOC monitoring must be performed offline using dedicated meters; the SZ-93 delivers purified water meeting baseline purity thresholds but does not provide real-time analytical feedback.
Is replacement quartz tubing available as a spare part?
Yes—Yarong supplies OEM quartz heater tubes (part number QH-SZ93-01) and fused quartz condenser sections (part number QC-SZ93-02), each individually tested for thermal shock resistance up to 1000 °C ΔT.
