When To Replace Your Biological Safety Cabinet

Use of modern day Biological Safety cabinets (BSC’s) began in the early 1970’s with BSC’s that were manufactured to the NIH-03-112C Standard and subsequently the NSF Standard 49. BSC’s manufactured in the 70’s, 80’s and early 90’s have provided over 15 years of service.

Several considerations should be made of BSC’s in this age group. Will the BSC need extensive service? (i.e. HEPA filter replacement, blower/motor replacement, will the electrical wire harnesses need replacement? etc.). Can an older BSC be commissioned after it has been in storage or purchased as a resale? Will original test reports be available or will the BSC be commissioned to current NSF Standards?
