Victorville, CA. Excel Scientific’s redesigned 50 mL Serological Pipets are constructed from high clarity virgin polystyrene.
They are certified RNase-, DNase-, pyrogen-free, and non-cytotoxic.
The smooth non-welded tip eliminates sample hang-up, leakage, and breakage. A 3 mm I.D. opening minimizes shear.
Sterile, individual one-side-paper, one-side-plastic packaging is easily opened by peeling or pushing through the paper.
A colored woven polypropylene plug provides easy size identification. There are forward and reverse 0.5 mL graduations with printed volumes at 1 mL intervals and negative graduations to -5.5 mL. Accuracy is ± 1.5 % and sterility better than 10-6.
