MBP biorobotix tips 200ul clear polypropylene, non-sterile Molecular BioProducts Low retention tips are for applications requiring high accuracy and reproducibility. The delivery of highly viscous liquids can be compromised by sample retention in the pipet tip. Low retention tips reduce sample retention by 3 to 5 times when compared with ordinary pipet tips. Tip is hydrophobic to reduce sample loss due to adhesion resulting in less liquid retention and improved liquid handling. HLT tips are compatible with all major thermal cyclers.
