Overview
The HS.Z68-5 Stainless Steel Electrically Heated Distillation Apparatus (Standard Model) is a benchtop-scale, continuous-feed steam-distillation system engineered for reliable production of Type III purified water in academic, pharmaceutical, and industrial quality control laboratories. It operates on the principle of thermal phase separation: feed water is heated to boiling within a stainless steel evaporation chamber; steam rises through a vapor path into a cooled condenser coil, where it undergoes phase reversal into liquid distillate. Non-volatile impurities—including ions, organic residues, endotoxins, and particulates—are retained in the boiling chamber and periodically drained during maintenance cycles. This physical separation method ensures consistent removal of >99.9% of dissolved solids, silica, heavy metals, and microbiological contaminants—making the unit suitable for preparing rinse water for glassware, reagent dilution, buffer preparation, and non-critical instrument feed applications.
Key Features
- Construction from fully welded AISI 304 stainless steel throughout all wetted surfaces—including evaporator chamber, condenser housing, and collection vessel—to ensure long-term corrosion resistance against chlorinated tap water and mild alkaline/acidic feed conditions.
- Integrated dry-run protection circuitry that de-energizes the heating element upon detection of low water level, activates an audible alarm, and initiates automatic refill via solenoid-controlled inlet valve before resuming heating—minimizing thermal stress on the heater sheath and extending service life.
- Dedicated LED status indicators for power supply engagement, active heating cycle, and low-water condition—enabling rapid operational verification without instrumentation dependency.
- Optimized vertical condenser geometry with high-surface-area copper-alloy cooling coils, passively air-cooled or optionally connected to a recirculating chiller (not included), ensuring stable condensation efficiency across ambient temperatures ranging from 15 °C to 32 °C.
- Front-access drain port and removable scale-collection tray facilitate routine descaling and chamber inspection in accordance with laboratory preventive maintenance schedules.
Sample Compatibility & Compliance
The HS.Z68-5 accepts municipal tap water, softened water, or pre-filtered feed sources with total dissolved solids (TDS) ≤ 500 ppm and free chlorine ≤ 2 ppm. It is not intended for direct use with seawater, brackish water, or wastewater streams. The distilled output meets or exceeds the specifications for Type III water defined in GB/T 6682–2008 (equivalent to ISO 3696:1987 Grade 3), including maximum conductivity ≤ 0.5 mS/m (at 25 °C), silica ≤ 0.1 mg/L, and oxidizable substances ≤ 0.4 mg/L KMnO₄. While not certified to ASTM D1193 or USP , its design supports GLP-aligned documentation practices when paired with manual logbook entries for batch number, start/stop time, operator ID, and output volume.
Software & Data Management
This apparatus operates as a standalone analog-electromechanical system with no embedded microcontroller, firmware, or digital interface. All operational parameters are fixed at factory configuration; no software installation, calibration files, or data export capability is provided. For regulated environments requiring audit trails (e.g., FDA 21 CFR Part 11 or EU Annex 11 compliance), users must implement external procedural controls—including handwritten logs, time-stamped photographic records of indicator states, and periodic conductivity verification using a calibrated handheld meter (e.g., Mettler Toledo SevenCompact™ S220). Optional third-party data loggers may be interfaced via dry-contact relay outputs (available upon request).
Applications
- Preparation of rinse water for volumetric glassware cleaning in teaching and research laboratories.
- Generation of solvent-grade water for HPLC mobile phase preparation where ultrapure (Type I) water is not mandated.
- Feed water supply for autoclaves, humidifiers, and environmental test chambers requiring low-mineral content.
- Supporting routine QC testing in chemical manufacturing facilities compliant with ISO 9001:2015 clause 8.5.2 (Identification and traceability of monitoring equipment).
- Backup distillation capacity during maintenance of central purified water systems in multi-user core facilities.
FAQ
What feed water quality is required to ensure optimal performance and longevity?
Tap water with TDS below 500 ppm and residual chlorine under 2 ppm is recommended. Pre-filtration through a 5-micron sediment filter and activated carbon cartridge significantly reduces scaling and extends time between descaling intervals.
Can this unit produce water suitable for cell culture or molecular biology applications?
No. The HS.Z68-5 delivers Type III water only. Applications requiring endotoxin-free, nuclease-free, or ultra-low-organic-content water (e.g., mammalian cell culture, PCR, or LC-MS) require additional purification stages—such as reverse osmosis, deionization, UV oxidation, and 0.22 µm filtration—provided by dedicated Type I ultrapure water systems.
Is routine maintenance documented in the user manual?
Yes. The supplied English-language operating manual includes step-by-step instructions for daily visual checks, weekly drain-and-rinse procedures, monthly descaling using citric acid solution, and annual inspection of gasket integrity and electrical continuity.
Does the unit include a built-in water storage tank?
No. The HS.Z68-5 is a continuous-output apparatus designed for direct collection into external containers. Users must provide compatible borosilicate glass or HDPE carboys rated for hot liquid handling.
What safety certifications does this model carry?
It conforms to GB 4706.1–2005 (Chinese national standard for household and similar electrical appliances – General requirements) and carries CCC (China Compulsory Certification) mark. CE marking is not applicable as it is manufactured and certified for domestic PRC market use only.
