Why Your Weighing Belongs in a Filtered Hood
Weighing in a filtered fume hood
The purpose of this paper is to show that accurate weighing results can be attained when choosing the proper combination of a balance within the appropriate ductless filtering fume hood.
Weighing requires accuracy, especially when the readability of a balance reaches 0,01 mg or more. In many applications the samples being weighed might be harmful or dangerous for the operator to inhale and the use of a filtered fume hood is required for the protection of the laboratory personnel.
When using a hood, air flow, drafts, and vibrations can adversely affect the weighing performance of a balance and eventually cause errors to the measurement.
ERLAB R&D LABORATORY
The engineers and chemists in our state-of-the-art R&D laboratory understand molecular filtration. We are committed to designing products that are safe and of the highest quality, strive to improve our products, and continuously develop new products that provide greater protection in the laboratory.
STRICT SAFETY STANDARDS
We hold ourselves to the highest standard and adhere to the strict AFNOR NF X 15-211: 2009 filtration safety standard as endorsed by ANSI Z9.5-2012.
A PUBLISHED CHEMICAL LISTING
It all begins here. Without this listing, we are not compliant with AFNOR NFX 15-211. Our in-house laboratory tests, as well as independent testing, to verify the retention capacity of over 700 chemicals for our filters.
INDEPENDENT TESTING
Erlab filters have been independently tested multiple times at various concentrations guaranteeing that our safety solutions all adhere to the strict performance criteria of theAFNOR NF X 15-211:2009 standard assuring that the emission concentration at the filter exhaust will always be lower than 1% of the TLV.
APPLICATION QUESTIONNAIRE (VALIQUEST)
Our laboratory specialists will recommend the appropriate filtration fume hood, type of filter, and personalized advice.
CERTIFICATE OF VALIDATION FOR THE CHEMICALS USED IN THE HOOD
A certified PhD chemist issues a Certificate of Validation with a list of the chemicals approved for use in the hood.
Our Safety Program
We back up our products 100%. This program includes your specialized chemical evaluation, validation of your hood upon installation, and a filtration safety specialist at your service to ensure that your hood is operating to its full potential.
