Laboratories Desiccators

Eureka Electronic Desiccator Cabinets for Laboratory and Educational Institutions

 Eureka electronic desiccator for microscopes in schools and labs   

Electronic Desiccator with automatic and renewable desiccant by Eureka Dry Tech.

 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.

  •  Common and traditional methods for moisture control in laboratories are desiccators made with heavy glass. These types of desiccators contain silica desiccant to absorb moisture.The downside to these traditional desiccants is the lack of control of relative humidity levels. Additionally, silica desiccant must be replaced regularly in order to remain effective.
  •  Other desiccator cabinets utilizes desiccants, nitrogen gas purge, or a combination of both desiccant and nitrogen to maintain a controlled environment. These cabinets are costly to purchase and maintain.

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.

Eureka Dry Tech's Auto Desiccator Products will provide:

  • 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. 

Moisture Controlled Storage for Hygroscopic/Deliquescent Agents, Standards and Chemical 

There are various types of hygroscopic materials in the lab. Any unintended exposure to moisture will affect the purity of the chemical or agent. Accuracy of the measurement will be affected since any moisture absorbed wil add to the weight. Hygroscopic powder material will tend to cake or clump when exposed to moist air. Excessive moistures in polymers will also result in unexpected affect during material processing.

​Eureka Dry Tech provides stable storage in ambient temperature environment for all types of chemical materials, agents, and samples in the laboratory. With wide range of  sizes & capacity and controllable relative humidity levels to <5%RH, Eureka Dry Tech has the perfect solution to meet your storage needs. Cabinets with custom features such as nitrogen purge, HEPA filter and windowless for photosensitive materials are also available.

Precision instruments in the lab are also sensitive to moisture. 

Excessive exposure to ambient humidity and high moisture levels 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. 

  • 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. 

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.Why allow these preventable damages to occur?
