Spray Specimen Preparation Workstation

Labtron’s spray specimen preparation workstation has calibration hinges on precision-controlled pressure regulators and sensors that maintain both atomization and liquid flow within tight tolerances. Advanced systems employ twin fluid or twin stage nozzles that adjust droplet size via air/liquid ratio and pressure, typically operating between 1–9?bar liquid and 1–6?bar atomizing air. The workstation monitors spray streams in real time, compensating for viscosity or temperature drift. Test panels are routinely used to validate spray uniformity, and calibration logs help ensure repeatability. Finally, nozzles with large free cross-sections minimize clogging and reduce maintenance. This setup ensures reproducible specimen coating critical for analytical integrity.

Once a coating ends, the system triggers an automatic cycle akin to solvent gun cleaners on the market Cleaning-solvent from the 5?L reservoir flushes the nozzle, followed by compressed-air blow out to remove residual droplets. A flow through brush or pulsating fluid enhances the removal of dried material. Venting via enclosed scrubbers captures any solvent mists or VOCs, safeguarding both equipment and user. Each cycle is logged in the control system, and solvent levels are tracked to prompt timely refill.

Labtron supplies premium models of spray specimen preparation workstation. To contain solvent vapours, the workstation integrates wet-scrubber or cyclonic-scrubber technology, where exhaust is passed through liquid sprays that capture particulates and droplets. Venturi-type wet scrubbers (operating at 50–150?cm of water pressure drop) can achieve >?99% particulate removal, with absorption efficiency tunable via liquid to gas ratios. Periodic automatic purges of the scrubbing tower maintain performance, and maintenance schedules include tank refill and drain. This design aids compliance with industrial VOC regulations, while keeping laboratory air clean.

Labtron supplies premium models of spray specimen preparation workstation. Immediately after spray, specimens move into a heating cabinet or infrared dryer integrated within the workstation. Specified parameters—such as 2?kW heat output reaching up to 150°C—are digitally controlled to ensure complete solvent evaporation and coating cure. The system uses sensors to verify temperature and exposure time, logging the cure cycle for process documentation. Automated transfer minimizes manual handling, preventing contamination or damage. Once dry, specimens are ready for downstream analysis or mounting without delay

Labtron’s spray specimen preparation workstation maintenance spans cleaning, inspection, and replacement protocols scheduled across intervals. Weekly checks include fluid-level monitoring, filter changes, and brush assembly cleaning. Monthly, nozzles and pressure sensors are inspected, and scrubber liquid is drained and replenished. Quarterly tasks include heating-element checks, cabinet fan upkeep, and ventilation line cleaning. Annual preventive maintenance covers software updates and full system diagnostics. Detailed logs are stored digitally to support audits, ensure calibration compliance, and prevent downtime.
