Sometimes the Microlab 600 instrument is exposed to harsh or dirty environments and maintaining these instruments is a constant task.  This section introduces a series of products designed to protect the instrument when it is exposed to these harsh environments including the AirShield with optional tubing and the Screen Protector.  The AirShield is designed to keep clean air flowing across the instrument and connections to limit corrosion from caustic fumes.  The optional tubing may be used when the instrument is in a more demanding environment which requires the fresh air to be brought in from outside the harmful environment.  In addition there is a Screen Protector that is designed to protect the controller from a chemical spill.

Localized Harsh Environment In many labs the air is relatively clean but samples and reagents placed near the instrument result in a localized environment that can be harmful. For these labs it is sufficient to source clean air from the back of the instrument away from the microenvironment.	Optional Snorkel for External Fresh Air Supply For labs with a more demanding atmosphere it is possible to source clean air via a snorkel that connects directly to the AirShield. Fresh air is then brought from outside the harmful environment to create a shield of clean air around all critical instrument components.
