Precision & Lab Equipment
Precision instruments are sensitive to moisture.
Humidity and moisture are present everywhere and can affect research lab instruments such as microscopes and other analytical equipment.

Microscopes
Recent advances such as the fluorescence microscope in microscope technology has provided some of the most precise optical instruments ever seen in the lab. But with all optical instruments, harmful fungus lurks around to cause damage to the lenses.
In regions where humidity is high, fungus build up 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 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.
This layer of synthetic material provides a wealth of nutrients for fungal growth and reproduction. Optical lens instruments maintained in high humidity areas may unknowingly allow fungus & mold to cultivate.
Once on set, 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.
- Whenambient temperature is above 10 ℃, humidity above 60% of the environment, mold begins to cause harmful damage.
- Whenambient temperature is at 20-35 ℃, humidity at 75-95%, mold growth will become explosive.
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.
THz Spectrometers
High ambient humidity content can cause issues can cause severe disruption 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.
With over 20 year experience in humidity control, Eureka Dry Tech has the capability of custom designing humidity control systems specific to your needs to pair with any terahertz spectrometer systems. Allowing test results to be as pure as possible with minimal atmospheric vapor caused signal attenuation as possible. Contact us today for further details.
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. Often times, it is too late when these damages are discovered. Why allow these preventable damages to occur? Contact us today for details on how Eureka can help you design a moisture controlled laboratory while providing costly laboratory equipment from invisible moisture attacks.
