Rainin LTS tip is specially equipped with Rainin pipette adapter pipette, and the tip is installed at the end of the pipette to form an airtight seal. Pipette tips are usually made of polypropylene, disposable, and available in a variety of specifications and volumes to suit specific applications and pipettes. The pipette tip is in direct contact with the sample, so the pipette tip will have a significant impact on the experimental results. Discarding tips between each experimental step helps prevent cross-contamination. BioClean refers to the extremely high standard of testing all BIOFOUNT air displacement tips and finding that they do not contain detectable amounts of specific biological contaminants, such as DNA (human and bacteria), RNase, DNase, endotoxin, protein, protease, ATP And PCR inhibitors.
