1) What steps does Burke Herring take to limit its environmental impact from ASHRAE 110 Testing?
Burke Herring uses tracer gases with low global warming impact indexes. We do not use the high global warming impact gas, SF6, and our principal member, Martin J. Burke pioneered the use of N2O as a replacement gas for SF6 after CAL/EPA prohibited SF6 use for routine ASHRAE 110 testing. We offer both N2O and FM200 gases for these tests, which have been rigorously tested and proven to be just as effective.
2) Do you employ NSF-accredited technicians?
Yes. In fact, our principal member, Martin Burke is the second-most senior NSF-accredited technician.
3) How often do biological safety cabinets (BSCs) need to be certified?
This varies from company to company. In R&D, most companies choose to certify their BSCs annually. FDA Aseptic Processing Guidelines recommend that manufacturing facilities and their equipment be certified semi-annually.
Our prices are very reasonable, typically 30% below our competition, and our standard certification is the most comprehensive available.
4) How much does BSC certification cost?
5) What tests are included in Burke Herring's BSC certification?
Downflow and inflow velocity tests using only primary test methods (flow hood), exhaust/supply HEPA filter leak tests, smoke tests, site assessment tests, particle counting to ISO Class 5, illumination, UV lighting, and electrical safety tests. We offer free example certification reports upon request!
