Inquiry (采购产品): Laminar Flow Hood Certification Hello, Can you please send me some more information regarding your hood certifications. An estimate of cost for a certification would also be appreciated. I have an old laminar flow hood (~ 25yr) which will likely need a new HEPA filter. Thanks. **** Hidden Message ***** Tracy Brenner 14456 Company: Cornell University, NYSAES Phone: 3157872266 E-mail: tlb86@cornell.edu **** Hidden Message ***** tlb86@cornell.edu
