BUNDLE TESTING PACKAGES

All of the testing performed by MicroStat Laboratories can be performed as individual tests, allowing the customer to design their own test matrix. However, certain aspects of product testing (new product development, comparative analysis, end-user qualifications) will often require the same group of tests to be performed. MicroStat Laboratories has bundled groups of tests together which will aid in developing product characteristic baselines, allow for comparative analysis versus competitive or current products, provide the typical information required in a product qualification, offered at a discounted price. These groups are typical for the product or for the industries evaluating the product.


CLEANROOM GLOVE TESTING BUNDLE
Gloves act as a barrier to Operator contributed contamination. However the gloves themselves may contribute to the contamination of the environment. The tests listed below are designed to qualify that contribution and allow the customer to determine the difference between products. Since the same glove is typically utilized in many applications, testing is typically conducted in both wet and dry environments, as well as different stress levels.

CLEANROOM GARMENT TESTING BUNDLE
Like gloves, garments provide a barrier to Operator borne contamination, while also having the potential to contribute contaminants. Unlike gloves, garments are not intended to be a complete barrier. They must allow moisture vapor to escape or "breathe" in order to be comfortable to the Operator. The combination of tests listed below is designed to determine the cleanliness of the garment, it's ability to filter out Operator borne contaminants, and it's ability to "breathe".

CLEANROOM BAG TESTING BUNDLE
Like gloves and garments, cleanroom packaging is designed as a barrier between the environment and what is contained within. In this case it is the contents that are being protected from the environment. Since most cleanroom packaging products come into direct contact with the customer's product, it is essential that the contact surface be as contaminant free as possible. Particles and fibers are generated during the manufacture of most packaging product. Laminar flow hoods, mini environments and post production cleaning are typical methods of reducing the contaminants. The tests listed below aid the end-user as well as the manufacturer in determining the effectiveness of the cleaning processes and the suitability of the materials in specific clean packaging operations. For packaging materials used in the electronic and microelectronic industries, ionic contamination and the ability to dissipate an electrostatic charge can be critical to the performance of the package.

CLEANROOM WIPER TESTING BUNDLE

As with most cleanroom consumables, the particle and fiber shedding characteristics of a cleanroom wiper (under varying degrees of simulated stress) are usually deemed the most critical. And since most cleanroom wipers have been designed for both wet and dry wiping applications, the sorbent rate and capacity is invaluable in determining the functionality of the wiper. Cleanroom wipers are typically used in very close proximity to the customer's products, sometimes even wiping the product itself. Knowing the non-volatile and ionic residue can therefore be extremely important to both the customer (in terms of potential contaminants) and the wiper manufacturer (in terms of processing consistency).
