JH-6D Automated Integrated Distillation System by Saprete

Overview

The JH-6D Automated Integrated Distillation System is an engineered solution for reproducible, unattended distillation in environmental, food safety, pharmaceutical, and regulatory laboratories. It operates on the principle of controlled dry-block heating combined with precise vapor condensation and gravimetric or volumetric endpoint detection—enabling standardized distillation per ASTM D129, ISO 6439, EPA Method 1671, and USP . Unlike conventional steam-heated or oil-bath systems, the JH-6D employs a ceramic heating module embedded in an aluminum thermal block, ensuring uniform heat transfer to quartz glass distillation tubes without direct flame or liquid medium contact. This architecture eliminates thermal lag, improves temperature stability (±1 °C), and enhances inter-run reproducibility—critical for compliance-driven workflows requiring audit-ready traceability.

Key Features

• Six independent distillation channels with fully programmable, channel-specific parameters—including target temperature, ramp rate, hold time, and endpoint volume or time threshold.
• Automated quantitative liquid dispensing prior to distillation, supporting pre-set volumes (e.g., 10–250 mL) with repeatability ≤±0.5% RSD across all six positions.
• Triple-mode condensation configuration: user-selectable between ambient tap water circulation, closed-loop chiller integration (with flow monitoring), or air-assisted passive cooling for low-power operation.
• Integrated endpoint determination via real-time condensate collection monitoring—either by weight-based threshold (using internal high-resolution load cell) or time-synchronized volumetric cutoff—minimizing operator intervention and over-distillation risk.
• Self-cleaning liquid pathway: post-run rinse sequence using deionized water or solvent, activated automatically or manually, reducing carryover and cross-contamination between samples.
• 7-inch capacitive touchscreen interface with multilingual OS support (English, Spanish, French), password-protected method libraries, and event-log timestamping compliant with ALCOA+ data integrity principles.

Sample Compatibility & Compliance

The JH-6D accommodates standard 250–500 mL quartz glass distillation flasks and receiver vials (10–100 mL), compatible with aqueous matrices, digestates (e.g., Kjeldahl digests), wastewater extracts, and volatile organic compound (VOC) preparations. All wetted parts are chemically inert—quartz, PTFE, and borosilicate glass—ensuring compatibility with acidic, alkaline, or oxidizing reagents (e.g., H₂SO₄, NaOH, KMnO₄). The system meets mechanical safety requirements per IEC 61010-1 and electromagnetic compatibility per EN 61326-1. Its software architecture supports 21 CFR Part 11-compliant user access control, electronic signatures, and immutable audit trails when connected to validated LIMS or ELN environments.

Software & Data Management

The embedded firmware includes method-driven operation with up to 99 stored protocols, each defining heating profile, distillate volume target, cooling mode, and post-run actions. Raw data—including real-time temperature, condensate mass/time curves, and system status flags—are logged in CSV format with UTC timestamps and exported via USB or Ethernet. Optional PC-based software (Saprete DistillLink™) provides graphical trend analysis, batch reporting (PDF/Excel), and deviation alerting. All data files include embedded metadata (operator ID, method version, instrument serial number), satisfying GLP/GMP documentation requirements for routine QC and validation studies.

Applications

• Determination of ammonia nitrogen (NH₃-N) in water and wastewater per ISO 5664 and EPA 350.1.
• Kjeldahl nitrogen analysis in food, feed, and soil samples following AOAC 984.13 and ISO 8968.
• Volatile phenol recovery from environmental samples (EPA 420.1, ISO 6439).
• Distillative separation of formaldehyde and other low-boiling aldehydes in textile and polymer testing (ISO 105-X11).
• Pre-concentration of trace metals (e.g., mercury, arsenic) prior to AAS or ICP-MS analysis using hydride generation or cold vapor techniques.

FAQ

What types of distillation methods does the JH-6D support?
It supports simple distillation, steam distillation, and vacuum-assisted distillation (when paired with external vacuum controller), optimized for nitrogen, cyanide, phenol, and volatile acid determinations.
Can the system be integrated into a laboratory automation framework?
Yes—it features RS-232, USB Device, and Ethernet (TCP/IP) ports for bidirectional communication with LIMS, SCADA, or robotic sample handlers using Modbus RTU or custom ASCII command sets.
Is quartz glassware included with the base configuration?
Yes—the standard delivery includes six matched quartz distillation tubes (500 mL), six quartz receivers (50 mL), and PTFE stoppers with gas-tight seals.
How is calibration verified and maintained?
Temperature calibration is traceable to NIST-certified reference thermometers; endpoint accuracy is verified using certified volumetric standards (Class A). Annual performance qualification (PQ) templates and IQ/OQ documentation packages are available upon request.
Does the system comply with environmental safety standards for fume management?
While not a fume hood replacement, the JH-6D’s sealed condensation path and optional exhaust adapter enable connection to centralized lab ventilation—meeting local occupational exposure limits (e.g., OSHA PELs) when operated in accordance with ANSI Z9.5 guidelines.
