About BrandTech 732008, 50 Mm. 2-200 UL Non-Sterile
50mm 2 - 200ul Non-Sterile Pipette Tip (Pack of 1000) Bulk: 1 bag x 1000 each All BRAND pipette tips are produced using the most advanced cleanroom techniques to ensure consistently high quality. The tips are manufactured in an environmentally friendly manner using only high-purity polypropylene, free from oleamide and diHEMDA - additives which can interfere with biological tests. Features Manufactured without lubricants Cadmium-free pigments Graduation for quick volume check All rack packed tips are free from DNA(less-than 40fg), RNase(less-than 8.6fg), ATP(less-than 1fg) and endotoxins (less-than 1fg). Autoclavable at 121 degree C (2bar), acc. DIN EN 285 Sometimes you will refer to "yellow" tips and "blue" tips in quotes. Why is that? Originally, all 200 uL pipette tips were colored yellow, and all 1,000 uL tips were colored blue. People would refer to them by their colors, as it was easier than specifying the size. Later it was determined that some of the dyes used to color the tips could interfere with their work. So colorless versions were developed of the tips, but often they were still called "yellow" or "blue" even though the tips were no longer colored. BRAND tips, when purchased bulk are colored for easier identification, but are free of cadmium dyes, which was the most problematic. BRAND tips, when purchased in racks are colorless to ensure no problems. The plates on which the tips are inserted are colored yellow, blue, dark gray or green for easy identification.
