IsoDry®: The Greatest in Desiccator Design

IsoDry desiccator cabinets are the latest, patent-pending innovation in desiccators from Terra Universal. Desiccators are containers designed to reduce relative humidity (RH) for moisture-sensitive stored items, either by purging the container consistently with nitrogen, using silica gel desiccants or pulling vacuum. The IsoDry desiccators use nitrogen to accomplish this task, both in achieving and maintaining a humidity “set-point.”

Dual Purge™ & NitroWatch™: The Dynamic Duo of Humidity Control

Desiccators are a safe means of storage for highly-sensitive samples or materials. A continuous purge of nitrogen or other process gas creates the positive pressure environment that’s conducive to a contamination- and humidity-free desiccator. But, what if a purging system allowed your desiccator to do more than just store parts? What if it also automatically reduced nitrogen costs and prevented overpressure? Terra’s Dual Purge system does exactly that—and when it’s paired with the NitroWatch humidity control system, the relative humidity percent set-point is automatically monitored and maintained. Keep reading to find out how this dynamic duo has changed the way we use desiccators.

5 Interesting Ways Industries are Using Desiccator Cabinets

Desiccants, more commonly recognized as those tiny packs of silica gel found in new shoes or luggage, have dozens of useful purposes in our daily lives. Some of the most effective desiccant gels can absorb up to 40% of their weight in moisture, protecting our gym bags from mildew or our silver jewelry from tarnishing. Although quite versatile, this household method of dry storage is usually not enough to preserve highly sensitive materials from moisture or contamination. Here are five critical specimens that you’ll find in a high performance, nitrogen-purged desiccator cabinet.

What’s Causing Your Desiccator to Leak, and How Do You Fix It?

When storing sensitive materials in a desiccator cabinet, unnecessarily high gas flow into the chamber or misalignment of the cabinet can lead to costly nitrogen waste. Positive pressure within a desiccator is meant to push unwanted moisture-dense air through the cabinet’s release valves and prevent the ingress of moisture-laden air. This continuous process leaks a small portion of gas, since desiccators are not 100% air-tight systems.  Let’s consider three of the top reasons why your desiccator may be leaking:

Insight Into On-Site Nitrogen Generation

Nitrogen, making up over 75% of the earth’s atmosphere, is our most common pure element. It can also be found in soil, bacteria and fossil fuels. Both plants and animals rely on nitrogen consumption (or its constituents) to maintain life; either in pure form, or when combined with other elements. Over the years, clever scientists and industrialists have found many practical uses for this colorless and odorless gas. Its inert nature makes it valuable for a wide range of applications, as well as safe to manage. The air around us is the most abundant source of nitrogen, and as necessity is the mother of invention, some of those same clever scientists developed ways to isolate and store it.
