Excel Scientific's redesigned 50ml serological pipettes are constructed from high-clarity virgin polystyrene.
They are certified RNase-, DNase- and pyrogen-free, and non-cytotoxic.
The smooth, non-welded tip eliminates sample hang-up, leakage and breakage.
A 3mm ID opening minimises shear.
Sterile, individual one-side-paper, one-side-plastic packaging is easily opened by peeling or pushing through the paper.
A coloured, woven polypropylene plug provides easy size identification.
There are forward and reverse 0.5ml graduations with printed volumes at 1ml intervals and negative graduations to -5.5ml.
Accuracy is +/-1.5 per cent and sterility better than 10-6.
