Overview
The ANYAN AYAN-DC60S Visual-Window Water Bath Nitrogen Evaporator is an engineered solution for high-throughput, reproducible solvent removal in analytical laboratories. It operates on the principle of gentle, inert gas-assisted evaporation—introducing precisely regulated nitrogen flow across the surface of heated liquid samples to accelerate solvent volatilization without thermal degradation. Unlike rotary evaporation or vacuum centrifugation, this method enables parallel processing of up to 60 samples under tightly controlled thermal and gaseous conditions. The water bath heating system ensures exceptional temperature homogeneity (±1 °C) across the entire sample block—critical for applications requiring strict thermal consistency, such as pesticide residue analysis, pharmaceutical stability testing, and clinical biomarker quantification. The dual transparent acrylic side panels provide real-time visual monitoring of sample status, tube positioning, and water level—enhancing procedural transparency and reducing operator intervention during extended evaporation cycles.
Key Features
- 60-position modular configuration with universal compatibility for tubes (10–29 mm OD), centrifuge vials, and conical flasks (1–50 mL capacity)
- Dual-side optical-grade transparent windows enabling unobstructed observation without opening the chamber or interrupting temperature/gas stability
- 7-inch capacitive touchscreen interface supporting 50-segment programmable temperature ramps, independent gas pressure control per channel (0–0.8 MPa), and timer-based endpoint termination (0–999 min)
- Stainless steel water bath tank with anti-corrosion coating and integrated water level sensor; compatible with ice-water mixtures for sub-ambient cooling applications
- Built-in axial exhaust fan and dual-sealed insulated door to minimize ambient moisture ingress and maintain consistent internal vapor environment
- Over-temperature cut-off, grounded 220 V/50 Hz power supply, and IP20-rated electrical enclosure compliant with IEC 61010-1 for laboratory equipment safety
Sample Compatibility & Compliance
The AYAN-DC60S accommodates a broad range of sample containers—including borosilicate glass tubes, polypropylene centrifuge vials, and screw-cap conical vials—without requiring dedicated adapter blocks. Its open-bath architecture eliminates dimensional constraints associated with dry-block systems, permitting heterogeneous tube geometries within a single run. The instrument meets general requirements for GLP-compliant sample preparation workflows when operated within validated SOPs. While not intrinsically 21 CFR Part 11 compliant, its digital log export capability (via USB) supports audit-trail documentation when paired with LIMS-integrated lab notebooks. It is routinely employed in methods aligned with AOAC Official Method 2007.01 (pesticide multiresidue analysis), EPA Method 525.3 (drinking water contaminants), and USP <467> residual solvents testing—where precise, low-thermal-stress concentration is essential.
Software & Data Management
The embedded firmware provides non-volatile storage for up to 20 user-defined protocols, each containing multi-step temperature profiles, gas pressure setpoints, and timed hold phases. All operational parameters—including actual bath temperature, elapsed time, and active alarm status—are continuously displayed and timestamped on-screen. Event logs (e.g., over-temperature events, door openings, power interruptions) are stored internally and exportable in CSV format via USB flash drive. No proprietary software installation is required; data files are human-readable and compatible with standard spreadsheet or ELN platforms. For regulated environments, users may implement external validation protocols covering temperature mapping (per ISO/IEC 17025), gas flow calibration (using traceable mass flow meters), and timer accuracy verification.
Applications
- Residue Analysis: Concentration of extracts from fruits, vegetables, cereals, and environmental water matrices prior to GC-MS or LC-MS/MS detection
- Clinical Toxicology: Preparation of plasma, serum, and urine samples for therapeutic drug monitoring and forensic screening
- Food & Beverage Quality Control: Solvent removal after QuEChERS extraction of mycotoxins, veterinary drugs, and flavor compounds in milk, beer, and fruit juices
- Pharmaceutical Development: Parallel evaporation of reaction intermediates and purified fractions during synthetic route scouting and impurity profiling
- Environmental Monitoring: Pre-concentration of semi-volatile organic compounds (SVOCs) from solid-phase extraction (SPE) cartridges in soil and sediment leachates
FAQ
Can the AYAN-DC60S be used with flammable solvents such as hexane or diethyl ether?
No. Due to the presence of heated water and electrical components, it must not be used with substances having flash points below 100 °C. Always consult SDS and operate inside a certified fume hood.
Is the water bath resistant to acidic or alkaline solutions?
The stainless steel tank is passivated and coated but not chemically inert to strong acids (e.g., concentrated HCl) or bases (e.g., >1 M NaOH). Use only deionized or distilled water; avoid direct contact with aggressive reagents.
How often should the water bath be cleaned and refilled?
Daily visual inspection is recommended. Replace water after every 3–5 runs or immediately if discoloration, scaling, or microbial growth is observed. Use biocide-compatible descaling agents if mineral buildup occurs.
Does the instrument support individual channel gas flow calibration?
Gas flow is regulated at the manifold level using precision needle valves. While per-channel flow cannot be digitally measured onboard, external mass flow meters (e.g., Brooks 5850E) may be installed for validation per ISO 5167.
What maintenance is required for long-term reliability?
Monthly inspection of seals, fan operation, and touchscreen responsiveness; annual verification of temperature sensor accuracy against NIST-traceable reference thermometers; biannual cleaning of exhaust ducts and condensate traps.
