The role of a pass through desiccator is very important in cleanrooms and labs. In fact in any laboratory where humidity and air pressure matters in production and environment control, there pass through desiccators must be used.

And they are common too. Two commonly used makes of pass-through desiccators are PVC made and Stainless Steel Desiccator Cabinets made.

Before you go for testing the performance of pass-through desiccators

Time to time testing of pass-through desiccators is important. If the instruments channelizing transfers between two rooms or compartments in a cleanroom does not gets tested for their ideal conditions, then items transferred may have altered humidity, or air leaking with them may alter environment of the compartment in cleanroom. To test the pass-throughs, you must first therefore know what exactly the instruments is supposed to help you at.

Why test pass-through desiccators

The role of the pass through Plastic Desiccator Cabinets is to give passage or channel between two different rooms or chambers, so that the air pressure, , and humidity levels of the controlled room stays the same and does not get altered due to multiple numbers of transfer of items inside and outside the room. There are two doors on either side of the instrument. When one door is opened to place an item inside the shelves of the storage box, then another door stay auto shut and can't be opened. And when this door is closed, then only the door on the other side can be opened to take out the item. This functionality ensures total control in retaining the controlled settings of the cleanroom.

Therefore, if the pass-through desiccators has to be tested for right performance, then:

  • The humidity of the item being transferred must be checked after transfer, and the humidity of the air inside the pass-through storage box must be checked.
  • The doors must not open together. Hence the door lock must be checked. When one door stays open another should stay auto locked. No force should be able to open the another closed door in any way.
  • There are gaskets on the doors to seal the doors air tight. From time to time these gaskets also need to be checked for their tightness.
  • The SDPVC coating or portion of the door panels must be checked that they are intact. These panels reduce the threat and chances of electrostatic
  • Look for any signs of corrosion or rust in a stainless steel pass-through desiccator.

When you check these things you actually check for the performance of the pass-through desiccator. However, you may need professional assistance in making all these checks.

Getting professional help

If you believe, you would need professional assistance to test the performance of any kind of pass-through desiccator you have, then you may call for testing professionals. They would come to the lab, test it, and give detailed report and certify it for being okay, or suggest needed repairs or replacements. This way also you may pass on the responsibility of testing to experts and stay sure that you are maintaining the optimum conditions in your cleanroom.

The domain of fashion illustration is extremely great but many people out there do not know that. The focus of fashion illustration is not solely bounded to human portraits as objects, jewelry and even anything related to the media is considered a part of it. It is a diverse field and if you begin to explore the realm of the fashion industry then you will be exposed to so many new features and details. The notion of drawing illustrations is becoming the norm now and those who think that they want a fashion illustration for themselves but do not know how to get on can always look for fashion illustrators for hire. Working with professional illustrators can allow you to know about the spectrum of this industry better and in turn, diversify your knowledge as well.

Here is what you need to know to draw illustrations that simply stick out:

Anatomy of the silhouette

The one thing that matters the most in a fashion illustration is the proportions of the silhouette you are drawing. Flaws in the anatomy a drawing are easily observable and correctly them consumes a lot of time. You have to practice thoroughly before you proceed to draw the actual illustration and with every stroke of line, analyze if you have kept the proportions anatomically accurate. Once you know how to master the shape and proportions of the illustration, you can easily add a clothing item and adjust it accordingly. The pose matters too and it varies on the kind of clothing your illustration figure is wearing.

Bring purpose to your illustration

Illustrations are generally static visuals but to make your fashion illustration stand out, you have to add a flair of style and persona to it. If it is like any other static visual then it would look to stagnant and boring to the viewer. Analyze what you want to draw first and who your audience then decides how much space you need on the canvas to make it look visually appealing. From the clothing items to the hair of the silhouette, every such little detail matters. If you are drawing a certain pose then it is important to display movement or the illustration would look unmoving.

Use space wisely

It is an art itself to utilize the space you have wisely. You could be drawing a scene of a park and with the extra details; your main design figure would lose its significance. A background that is cramped with too many details is never considered visually appealing so you have to smartly align the objects on a blank canvas and not necessarily consume any space that you see. Try to keep a minimalistic and simple background so that the attention of the viewer does not divert to the background but sticks to the core figure of your illustration.

Patterns in design

Patterns play a key role in clothing and there are several kinds of it. Some patterns have existed as popular trends throughout history and they are still prevailing. Since these patterns have existed for centuries, each of these also has a story to tell. If you master the notion of understanding patterns and understand how to use them in a certain illustration, the process of illustration creation will become easier for you.

Perception varies

When you look at an illustration, you build a perception about it and it is likely that your observation would not be similar to others and other people would have different views about it. That is why it is said that illustrations entirely depend upon perception and it varies from person to person. The viewer is the one that creates meaning for what he sees but if you are drawing a fashion illustration then it is better to use simplistic visuals and try not to complicate the design too much.

Design optimization

A certain style is more often used for the anatomy of fashion illustrations. Some tend to stick to sleek fashion figures while some illustrators experiment various design styles and merge them together. However, you have to create your illustration in such a manner that it brings the attention of the viewer to the exact element you want his focus to be. The anatomy of fashion illustration varies from the standard proportions and you have to chance those proportions into a design that enhances the average anatomy features that we see.
