Electronic Laboratory Desiccator with automatic and renewable desiccant.

Electronic Laboratory Desiccator with automatic and renewable desiccant.

Chemicals in laboratories are hygroscopic and any humidity in the ambient environment will cause contamination to those chemicals when improperly stored or handled. Samples & specimen in the laboratory may also suffer from contamination caused by ambient humidity.

Eureka Dry Tech's electronic desiccators utilizes multi-porous molecular sieves providing renewable and controllable desiccating capabilities. Nitrogen (N2) purging is not necessary for desiccating functions. Eureka Dry Tech's automatic desiccator cabinets are quiet, and consumes minimal electricity and comes in various sizes and shapes, allowing storage of large amounts of samples, specimen, chemicals and other moisture sensitive items in the lab.

  • Ambient temperature dehumidification. Specimens will be protected from qualitative change or condensation damage. 
  • Fully automatic and power-saving (about $50 NT (less than $2 USD  monthly electricity bill) with silent operation. 
  • Specimen storage conditions can be maintained with automatic control of specific humidity range while eliminating specimen contamination.
  • Long-term and stable dehumidification, prevents damages from ambient temperature changes where fluctuation is significant.
  • Safe and continuous protection even during long-term power outages. 

Prolonging Lifespan of Precision Instrument in the Laboratory

Excessive exposure to ambient humidity and high moisture levels can affect research lab instruments such as microscopes and other analytical equipment.

Eureka Laboratory Desiccator Protecting Microscopes from development of lens fungus


In regions where humidity is high, fungus development is common with microscopes lenses. Typically, fungi require relatively high temperature and humidity for optimal growth. However, two strands of the Aspergillus fungus that are adaptable to lower humidity levels and are most common causes of lens deterioration.

Modern variety of professional lenses utilized to improve analytical performance, are coated with multi-layer film composed of a polymer material which provides a wealth of nutrients for fungal growth and reproduction. Once onset, fungi will consume the optical lens surface film and spread on the surface of the lens, interrupting light transmission and image deterioration, until mycelium covers the entire lens.

  • When ambient temperature is above 10 ℃, humidity above 60% of the environment, mold begins to cause harmful damage.
  • When ambient temperature is at 20-35 ℃, humidity at 75-95%, mold growth will become explosive.

Mold spores growth rate based on temperature conditions

Although fungi growth on glass surfaces are not attached by roots and can be wiped off, but residual corrosion marks remain and the original lens performance cannot be recovered and the lens must be replaced. Prevention is the key to effectively avoid fungal damage to optical. Fungal contamination can be minimized by reducing the humidity of the room with costly air conditioning running constantly. Or for the most economical and effective method is to store microscopes in Eureka’s dry cabinet products.

Eureka Dry Tech offer's cabinet in various sizes, shapes and with different desiccating capabilities. If our standard product isn't what you are looking for, we will custom design a cabinet to suit your humidity controlled storage needs.

Laboratory Sampling Instruments

High ambient humidity content can cause issues can cause severe disruption to instruments like  THz Spectrometers when research, analysis and development requires the purest test results. Studies have shown that water vapor in the atmosphere can cause attenuation to electromagnetic waves from low frequencies up to 2 terahertz. Atmospheric humidity changes daily with weather, seasons, fog, rain and temperature. Since it is impossible to control mother nature the only solution would be to control the humidity levels where the terahertz signal transmission occurs.

Other moisture sensitive items in the lab

Many other instruments and accessories are sensitive to ambient moisture & humidity. Rust, oxidation, condensation, fungus and other issues are constantly attacking costly equipment.Why allow these preventable damages to occur?
