Brady B33-155-490 B-490 FreezerBondz Cryogenic Laboratory Label, 41.28 x 15.24 mm

Brady B-490 FreezerBondz is a matte polyester label made to mark laboratory samples that go into liquid nitrogen and freezers. This listing has four die-cut sizes for B33 series printers, from 41.28 x 15.24 mm to 95.25 x 38.1 mm, on cartridges of 1000 or 1500 labels (manufacturer-stated).

B-490 is 0.07 mm (0.0026 in) thick with an aggressive permanent acrylic adhesive. Brady says it marks lab samples on smooth surfaces in liquid nitrogen and freezer environments, and lists it as chemical, smear, UV and weather resistant (manufacturer-stated). Brady's description gives a working range of -196 to 100 °C, while its specification table shows a higher upper figure, so this page uses the lower range (manufacturer-stated). Brady recommends it for flat, smooth surfaces and does not recommend outdoor use. Brady names B30-R4300 as the ribbon and gives a vial or tube size for each label, from 4 mL to 50 mL (manufacturer-stated). Brady's page title describes this material as cryogenic and does not list autoclave use, so confirm with us before using it in an autoclave. Figures are Brady published values (manufacturer-stated).

Two numbers identify each product. The product code is Brady's alphanumeric part number, and it is the code to search for or quote. The Brady ordering number is the six-digit number Brady uses for the same product. Both are in the table below, and the Product Code shown for each option on this page is the part number.
