Bovine serum albumin (BSA) is used extensively as a carrier protein to dilute antibodies and as a general protein blocking agent in immunoassays and immunodetection protocols. Our IgG-free BSA, which is also protease-free, should alleviate many of the problems associated with using BSA. Many preparations of BSA, even some of the highest purity grades, contain IgG that may become an antigen for cross-reacting secondary an…

These burets are designed for precise analytical methods in microchemistry. Precision bore tubing throughout the body assures accuracy between any two points. Funnel top facilitates addition of reagents by pouring, or by suction from below, through a rubber-stoppered tube. Tips are tapered to assure smooth flow. Stopcocks turn freely, yet give positive control and are of 2 mm bore. The capacity tolerance on these burets is est…

These 100mL PYREX® graduated cylinders are calibrated "to contain” (TC). The scale and figures are durable white enamel, which stand out clearly against the red color-band on these Lifetime Red™ cylinders. This provides clear, accurate measurements for delivering or containing liquids. The 100mL size is made in accordance with ASTM E-133 and E-1272 and is used in ASTM tests D-86 and D-216. Bumper guards are supplied. For repla…

These 100 mL PYREX® graduated cylinders are calibrated (TC). The scale and figures are durable white enamel, which stand out clearly against the red color-band on these Lifetime Red™ cylinders. This provides clear, accurate measurements for delivering or containing liquids. A reinforced bead of glass near the top helps to reduce breakage, if the cylinder upsets. These cylinders are in accordance with ASTM E-133 and E-1272 and…
