Yarong SZ-96A Quartz Glass Distillation Apparatus

Overview

The Yarong SZ-96A Quartz Glass Distillation Apparatus is a benchtop, electrically heated purification system engineered for the reliable production of high-purity distilled water in research laboratories, quality control environments, and small-scale analytical workflows. Designed around a vertical single-stage distillation principle, it employs resistive heating via enclosed quartz tube elements to vaporize feed water without direct metal contact—minimizing ion leaching and ensuring consistent purity output. The apparatus operates under atmospheric pressure and utilizes gravity-driven condensate collection, with thermal and hydrostatic feedback loops enabling autonomous termination at defined endpoints. Its all-quartz and high-density borosilicate glass construction eliminates metallic contamination pathways, making it suitable for applications requiring low-conductivity water (e.g., trace elemental analysis, buffer preparation, and reagent-grade solvent generation).

Key Features

• Quartz tube heating assembly: Provides stable, uniform thermal input with rapid response and no metallic sheath—critical for maintaining ultra-low background conductivity in distilled output.
• Metal-free condensation pathway: Entire vapor-to-liquid transition occurs within quartz and borosilicate glass components; cooling water circulates externally via a sealed, non-contact jacket—preventing cross-contamination from copper, stainless steel, or nickel alloys.
• Dual-mode endpoint detection: Integrated temperature controller monitors vapor-phase temperature rise (indicating dry-out), while a reed-switch-based water level sensor detects falling reservoir level; both signals trigger relay cutoff to halt heating automatically.
• Relay-protected electrical architecture: Includes over-temperature cutoff, short-circuit protection, and fail-safe power interruption—compliant with IEC 61010-1 safety requirements for laboratory equipment.
• Compact footprint and modular design: 70 × 20 × 68 cm dimensions accommodate standard lab benches; lightweight (5.4 kg) construction facilitates repositioning without structural reinforcement.

Sample Compatibility & Compliance

The SZ-96A accepts municipal tap water, deionized water, or pre-filtered feed sources with total dissolved solids (TDS) ≤ 500 ppm. It is not intended for seawater, highly saline brines, or organic solvent mixtures. Output water typically achieves resistivity ≥ 1.0 MΩ·cm (25 °C) when fed with low-TDS source water and operated under controlled ambient conditions. While not certified to ISO 3696 or ASTM D1193 Type II/III specifications out-of-the-box, the apparatus supports GLP-aligned operation when paired with documented calibration of temperature sensors and routine verification of distillate conductivity. No regulatory certification (e.g., FDA, CE, or UKCA) is provided by the manufacturer; users are responsible for site-specific validation per internal SOPs.

Software & Data Management

The SZ-96A is an analog-controlled instrument with no embedded microprocessor, digital display, or data logging capability. All operational parameters—including heating activation, endpoint sensing, and power cutoff—are managed through discrete electromechanical components (bimetallic thermostats, magnetic reed switches, and electromagnetic relays). Consequently, no software installation, firmware updates, or computer interface is required or supported. This architecture ensures long-term reliability, immunity to electromagnetic interference, and compatibility with environments where IT infrastructure is restricted (e.g., radioisotope labs, explosion-proof zones). Process documentation must be performed manually using lab notebooks or external data acquisition systems connected to auxiliary temperature or flow sensors.

Applications

• Preparation of low-conductivity water for atomic absorption spectroscopy (AAS), inductively coupled plasma mass spectrometry (ICP-MS), and ion chromatography (IC) mobile phase dilution.
• Generation of purified water for pharmaceutical QC testing where metal-free steam is not required but residual ion content must remain below method-defined thresholds.
• Supporting educational laboratories in teaching fundamental separation principles—including phase change thermodynamics, latent heat transfer, and vapor–liquid equilibrium behavior.
• On-demand distillate supply for calibrating conductivity meters, preparing electrophoresis buffers, and rinsing high-sensitivity optical components.

FAQ

Is the SZ-96A compliant with ISO 3696 or ASTM D1193?
No—this unit lacks third-party certification to either standard. Users must validate output water quality against their own acceptance criteria using calibrated conductivity/resistivity meters.
Can it distill seawater or brackish water?
No. Feed water TDS should not exceed 500 ppm to prevent scaling, premature sensor fouling, and reduced distillate purity.
Does it support continuous unattended operation?
Yes—its dual-sensor endpoint control enables safe overnight or extended runs, provided ambient temperature remains stable and coolant circulation is uninterrupted.
What maintenance is required?
Quarterly descaling of the quartz boiling chamber with dilute nitric acid (≤5% v/v), annual inspection of reed switch alignment, and biannual verification of thermostat setpoint accuracy using a traceable NIST-calibrated thermometer.
Is replacement quartz tubing available as a spare part?
Yes—Yarong supplies OEM quartz heater assemblies (P/N: QH-SZ96A-01) and condenser tubes (P/N: CT-SZ96A-02) under standard distributor channels.
