Product Description
Precise contained-volume readings and a reliable ground-glass seal make these tubes a good fit for analytical separations. The heavy-duty glass stands up to routine centrifuging and repeated washing. They are well suited to labs that need reusable, sealable tubes. Each tube is reusable after cleaning.
This listing is for Kimble catalog number 45176-13: Heavy-Duty Graduated Centrifuge Tube, 13 mL, Case of 6. Made from borosilicate glass 3.3 meeting USP Type I and ASTM E438, Type I, Class A, they are calibrated to contain and finished for a standard taper flat head stopper. The 13 mL size has a red-stain scale and the 50 mL size a brown-stain scale, both with a sandblasted marking spot. Rated to 2050 RCF; remove the stopper before spinning. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
