SPAN TABS
Water Baths/Incubator
My name is Brad Callen and I represent the company of CR CALLEN LLC. I have received requests to update one of our most popular products. The product’s name is Span Tabs. Span tabs are used in your water bath/incubator environment’s to prevent many forms of algae’s, bacteria’s, and fungi from growing and infecting what you are trying to culture. Span tabs come packaged in bottles of 75 blue tablets. How many tablets you use depends upon the size of the incubator/water bath. As the blue color fades you just drop-in another tablet! This saves you the expense of having to clean your baths out monthly, etc.
CR Callen has sold Span Tabs and our other lab tested cleaning products worldwide in many high tech Cancer Research Centers, the Bio-Tech field, and now we are being used in Stem Cell research enviroments.
