Hench Implements MRD-300Plus Infrared Desiccator for Coastal Laboratory
1月 20, 2026
Customer Background
A leading Southeast Asian polymer materials company specializes in high-performance polymer research and development. Their laboratory is equipped with two Fourier-transform infrared (FTIR) spectrometers and one infrared microscope, primarily used for polymer structure characterization and compositional analysis. The lab routinely stores large quantities of polymer powders, infrared standards, and precision testing accessories.
Located in a coastal region with high humidity and elevated salt levels in the air, the laboratory faced significant challenges in preventing moisture and corrosion. Maintaining precise instruments and sample integrity was critical to ensure accurate testing and efficient R&D operations.
Core Challenges
Instrument Corrosion and Sensitivity Loss: Coastal high-humidity and salt-laden air caused corrosion on optical components of FTIR instruments, reducing sensitivity. Detecting low-concentration components became unreliable, delaying R&D.
Sample Moisture and Aggregation: Polymer powders absorbed moisture and clumped together, making uniform tablet pressing difficult. Infrared test results were inconsistent, leading to repeated formulation errors.
Inefficient Conventional Dehumidification: Traditional dehumidifiers required constant operation, consuming high energy. When full, they slowed down dehumidification, preventing new samples and accessories from reaching stable humidity levels quickly.
Hench’s Solution
Hench provided a customized MRD-300Plus infrared desiccator (compatible with Thermo IS50) tailored to the client’s coastal laboratory environment. Key product features included:
Sealed Design: Gas-tight closure with imported silicone gaskets, providing strong anti-oxidation protection and excellent internal sealing.
Robust Construction: Cabinet body made from 1.5mm rolled steel with a 5mm reinforced load-bearing base coated with anti-static and flame-retardant spray. Internal joints sealed with cured adhesive for optimal airtightness.
Advanced Dehumidification: Smart humidity sensing modules with high-capacity absorbent molecular layers and microcomputer-controlled operation. Automatic dehumidification starts when humidity exceeds the set threshold, without consumables, ensuring long-term reliability.
Power Failure Protection: During power outages, chemical absorbents maintain moisture protection, limiting humidity rise to less than 10% within 24 hours.
Results After One Month
Instrument Performance: FTIR optical components remained free of corrosion and moisture. Sensitivity returned to near-new levels, with low-concentration detection accuracy exceeding 95%.
R&D Efficiency: Polymer powders stayed dry, ensuring smooth tablet formation. Infrared testing became precise, reducing formulation adjustment cycles from 15 days to 7 days, accelerating R&D progress.
Environmental Adaptation: The desiccator maintained stable humidity during typhoons and heavy rain, preventing salt corrosion. Samples and accessories were safely stored.
Cost Control: Reduced replacement of damaged samples and instrument maintenance saved approximately ¥3,000 per month and lowered instrument upkeep costs by 70%.
