Overview
The Anyan AYAN-DC36S Fully Enclosed Water-Bath Nitrogen Evaporator is an engineered solution for high-throughput, reproducible solvent removal in analytical and preparative laboratories. It operates on the principle of inert gas-assisted evaporation: nitrogen gas—preheated to approximately 45 °C—is delivered via precision-controlled, independently regulated channels directly above sample tubes immersed in a thermostatically maintained water bath (ambient to 100 °C). This dual-thermal strategy accelerates solvent volatilization while minimizing thermal degradation, oxidation, or cross-contamination. Unlike open-top or dry-block evaporators, the AYAN-DC36S features a fully sealed chamber with dual transparent viewing windows and a dual-gasket door system, ensuring containment of volatile organic compounds (VOCs), compliance with laboratory ventilation safety protocols, and elimination of ambient air ingress during concentration. Its design reflects collaborative input from academic researchers and QC labs seeking robust, auditable, and operator-safe sample preparation workflows.
Key Features
- 7-inch capacitive touchscreen interface supporting intuitive navigation, real-time parameter monitoring, and multi-user access control;
- 50-segment programmable temperature ramping across five distinct operational modes (e.g., constant temperature, gradient heating, hold-and-ramp), enabling method standardization across diverse analytes;
- Fully enclosed chamber with dual optical-grade acrylic viewing windows (front and side) and integrated LED illumination for unobstructed, parallax-free visual monitoring of meniscus levels and evaporation progress;
- Independent digital mass flow control per channel (0–999 mL/min) with pressure-regulated solenoid valves (0–0.8 MPa), ensuring uniform gas distribution and eliminating inter-channel variability;
- Preheated nitrogen delivery system maintains consistent gas temperature (~45 °C) at the needle tip, preventing condensate formation and reducing risk of sample redeposition or carryover;
- Dual-seal door mechanism combined with an internal recirculating fan and activated carbon–enhanced filtration ensures zero VOC leakage and eliminates dependency on external fume hoods;
- Built-in data logging captures time-stamped records of temperature setpoints, actual bath temperature, gas flow rates, elapsed time, and alarm events—exportable via USB for audit trail generation;
- Modular aluminum heating block (16 mm tube diameter, configurable for alternative diameters) with rapid thermal equilibration and ±1 °C temperature stability across all 36 positions.
Sample Compatibility & Compliance
The AYAN-DC36S accommodates standard 16 mm OD glass or polypropylene test tubes, microcentrifuge tubes (with optional adapters), and HPLC vials. Its sealed architecture supports safe handling of Class II/III solvents (e.g., dichloromethane, ethyl acetate, hexane, methanol) per OSHA 29 CFR 1910.1200 and EU CLP Regulation (EC) No. 1272/2008. The instrument’s temperature control system complies with ASTM E2758–19 for laboratory evaporator performance verification. Data logging functionality supports GLP/GMP environments when paired with user-defined electronic signatures and audit-ready export formats. While not FDA 21 CFR Part 11–certified out-of-the-box, its timestamped event logs and password-protected method storage align with foundational data integrity expectations for regulated QC labs.
Software & Data Management
No proprietary software installation is required—the device operates autonomously via its embedded Linux-based firmware. All operational parameters, method files, and run history are stored internally in non-volatile memory with automatic timestamping. Users may export CSV-formatted logs (including date/time, setpoint vs. actual temperature, flow rate per channel, and error codes) via USB-A port for integration into LIMS or ELN platforms. Up to 100 method templates can be saved and recalled; each includes full temperature profile definitions, gas flow sequences, timer settings, and alarm thresholds. Password-protected administrator mode enables calibration offset adjustments and system diagnostics without exposing routine operators to configuration risks.
Applications
- Residue analysis in food safety testing (pesticides, mycotoxins, veterinary drug residues);
- Environmental sample preparation (PAHs, PCBs, organochlorine pesticides in water, soil, and sediment extracts);
- Pharmaceutical impurity profiling and stability-indicating assays requiring low-temperature, oxygen-free concentration;
- Clinical toxicology workflows involving urine or plasma samples prior to GC-MS or LC-MS/MS analysis;
- Forensic chemistry applications where chain-of-custody integrity and VOC containment are mandatory;
- Academic research labs performing parallel synthesis workups or natural product isolation requiring precise, trace-level solvent removal.
FAQ
Does the AYAN-DC36S support validation documentation (IQ/OQ/PQ)?
Yes—factory-provided calibration certificates for temperature and flow sensors are available upon request. Users may perform OQ using ASTM E2758 test protocols with supplied reference thermometers and calibrated flow meters.
Can the unit operate continuously for >24 hours?
Yes. Designed for unattended overnight operation, it includes over-temperature cutoff, gas-flow failure detection, and automatic shutdown on timer completion.
Is tube size customization supported beyond 16 mm?
Yes—optional interchangeable blocks accommodate 10 mm, 12 mm, and 20 mm diameter tubes; custom machining is available for specialized formats.
How is nitrogen consumption minimized?
Through preheated gas delivery, independent per-channel solenoid valving, and dynamic flow modulation based on real-time evaporation rate estimation—reducing typical N₂ use by up to 40% versus conventional open systems.
What maintenance is required?
Quarterly cleaning of the water bath reservoir and ultrasonic degassing of the heating block; annual verification of temperature sensor accuracy and door seal integrity.
