3,3-Diaminobenzidine (DAB) pure, 98%

The Universal Fit-Neptune 0.5–10 µL XL pipette tips are extra-long tips made from pure polypropylene for accurate handling of very small liquid volumes. They are built to fit most common pipette brands and deliver precise transfer between 0.5 and 10 microliters. The XL length allows access to deep or narrow tubes without contamination from contact with the tube walls. The inner surface is very smooth to prevent liquid from sticking inside the tip, which helps reduce sample loss. These tips are available with or without aerosol barriers and come in sterile or non-sterile formats. Sterile tips are certified free of RNase, DNase, pyrogens, and ATP. They can be autoclaved without melting or warping. The tips come in rack, bulk, or reload packaging and are designed for consistent fit and secure sealing on most pipettes.
