Company needs materials laboratory for Failure Analysis Testing of welded seam strength in air supported structures made out PVDF 28oz vinyl fabric. The seams of the fabric are RF welded together to create the structure and we have been having some issues with our seam strength lately
Environmental Microbiology Laboratory needed for efficacy study for the usage of choline dioxide gas in the deactivation of mycotoxins, specifically tricothecene, aflatoxin, ochratoxin, and gliotoxin. Additionally, what is the chemical make up of the fragments left after oxidation.
Laboratory needed for quantitative analysis of DEHP and DEHT. Must extract a resin from peristaltic pump tubes and then within that resin find the DEHP and DEHT levels in ppb. The resin is approximately 3% of the tubing composition and the DEHP and DEHT is approximately 1% each of that.
Microbiology laboratory needed for microbiological testing of production facility including water testing and air testing of various areas around production lineincluding plastic closures, preforms and conveyors.. Microbiology testing to include mold/yeast, total bacterial, and coliform separately. Tap water in the production area will also be tested in the production area.
How do you go about and do these test. Does one of your technicans come on site or do I provide the samples?
USA Microbiology Laboratory needed for microbiological analysis:for validation the bacteriostatic properties of filters using microbiological test agents like aerobic mesophilic bacteria, fungi / yeast (Botrytis), and Listeria monocytogenes. 2) ALso, testing for the validation of the application of filters under strict operating conditions and will require proof of the following: a. A hood or container where it can perform a microbiological load, or bioburden natural environment is taken b. That bell or container must be allowed to have 2 rooms separated by the filter and allow re-circulation of air c. measurements should be made of the bioburden of the air before filtering and after filtering d. recirculate air and pass it through the filter, microbiological components go through the filter and are retained and destroyed e. Thus, the comparison of measurements over time, allow to observe the reduction of bioburden. For reference, a test according to DIN 71460-1 conducted in Germany described that instead of a pre-cleaned air, environmental spray test room with natural exposure to bacteria and germs such as spray test is used. With the corresponding samples is performed a selection of specific bacteria in culture media used for the subsequent incubation of the microorganisms collected. The flow rate is in turn 354 m3 / h, but we suggest a rate of 5 m3 / h. In each case six samples are collected in the contaminated side and the filtrate side, for a period of one day. Thus they are determined in each environment (contaminated and filtered) CFU / m3 (colony forming units) and thus reducing the number of germs occurred by the filter or filtration is determined. Taking air samples it is done with the device microbiological air sampling MAS-100 of the Merck brand. The culture medium is subjected to a sample volume of 100 liters or 250 liters. To determine bacterial counts in the culture medium, it is evaluated according to the above method, after 3 days incubation at 30 °C. The detection limit of the sub-search method is 4 to 10 CFU per m3.
Contract Laboratory needed for evaluation of the efficiency of air filtration media at adsorbing common gas phase pollutants. We are particularly interested in nitrogen oxides, carbon monoxide, and sulfur dioxide. The test must quantify the upstream challenge to the air filtration media and quantify the efficiency at which the media absorbs the pollutants. A face velocity of 5.7 cm/sec is the desirable flow rate but we will likely alter this for future testing. Please specify your ability to adjust temperature and humidity.
USA Laboratory needed for smoke testing of lamiar flow hoods to of pump hardware that need to be aerodynamic such that it does not create dead spots in a laminar flow hood. We need to tests whether it create dead spots in the laminar flow hood. This is determined using a smoke test.
