Automatic Spray Specimen Preparation Workstation

Labtron’s automatic spray specimen preparation workstation employs precision-controlled pressure regulators linked to high-resolution sensors, ensuring that liquid and atomizing air stay within set tolerances. Nozzles—often servo-driven—operate between defined pressure ranges (e.g., up to 0.7?MPa) to control droplet size and coverage, and spray speed is adjustable (e.g., 0–500?mm/s) to tune film thickness accordingly. Real-time feedback adjusts flow automatically to compensate for viscosity or solvent-level changes. Operators validate performance using reference test panels and record calibration data in the system’s log. Uniform flow ensures reproducible coatings and analytic accuracy. Regular nozzle checks prevent drift from specifying errors. Together, these controls maintain uniform specimen preparation.

Labtron supplies advanced models of automatic spray specimen preparation workstation. After a coating cycle, the workstation initiates a "solvent flush–air purge–rinse–air purge" sequence to clean the application gun. Solvent is pumped from the 5?L reservoir to flush internal channels, followed by compressed-air blast to clear residues. Often a brushing ring or agitation enhances cleaning efficiency. Waste solvent returns to a holding tank for disposal or recycling. Enclosed ventilation captures any vapor, directing it to scrubbers or filters. Every cleaning cycle is digitally logged, with solvent level monitoring triggering refill alerts. This comprehensive protocol mitigates nozzle clogging, ensures spray quality, and supports hygienic operations and operator safety.

The exhaust system integrates wet or spray-tower scrubbers to capture solvent mists and vapors efficiently. Counter current spray schemes direct solvent or water sprays across ventilation flow, capturing droplets in scrubbing towers and using mist eliminators to separate cleaned air. Packed-bed or Venturi-style scrubbers may be employed to enhance removal of fine droplets and VOCs. Periodic automatic purges maintain scrubber efficiency, while sensors track liquid levels, trigger replenishment, and monitor air quality. This design achieves regulatory compliance, keeps lab air clean, and reduces environmental impact.

Labtron supplies advanced models of automatic spray specimen preparation workstation. Immediately after spray application, specimens are transferred into an integrated drying or curing zone—often a heated chamber or infrared dryer capable of reaching ~150?°C, powered around 2?kW. Temperature and duration are pre-programmed and monitored via sensors for repeatability. Automated transfer mechanisms, such as robotic arms or conveyors, minimize manual handling and cross-contamination risks. Every drying cycle, including parameters and timestamps, is logged for traceability. Once cured, specimens are ready for analysis or packaging without further intervention, streamlining workflow efficiency and ensuring consistent preparation standards.

Maintenance follows a scheduled rhythm: weekly tasks include reservoir-level checks, lint trap or filter clearance, and visual inspection of chambers; monthly tasks cover nozzle and sensor calibration, solvent-filter replacement, and scrubber liquid refresh. Quarterly checks involve heating-element diagnostics, fan/filter servicing, and ventilation integrity. Annual preventive maintenance includes full calibration, software updates, and system diagnostics, often performed by certified engineers. All tasks are logged digitally, maintaining audit-ready records. This routine upkeep ensures uptime, consistent output quality, compliance, and safety across operations.
