Bulk Test Tubes are neatly packaged in heavy duty boxes of 250 and are shrink wrapped to keep them particle free. The boxes are compact and designed to fit into most test tube dispensers. Ideal for tissue culture and blood banks. Tubes feature well-rounded bottoms and smooth fire-polished rims. Made from chemically inert borosilicate glass to reduce pH changes and contaminants that are potentially leached from tubes made from soda lime glass. Produced in an ISO 9001:2008 certified factory.
