CELLTREAT Scientific Products Pipette Tips deliver high performance with exceptional value. A perfected balance between raw materials and efficient manufacturing processes results in superior low retentionPipette Tips have smooth, hydrophobic surfaces to ensure accurate pipettingMultiple Pipette Tip sizes are available, including extended length tips (10μL and 1000μL) to allow better access to the bottom of test tubes, reagent bottles, flasks and other vessels200μL filter tip is longer than standard tips for better access to vessels and increased headspace to filterPipette Tip racks feature hinged lids that are designed for asy one-handed opening, making it easier to access repeatedly Pipette Tips are universal fit and compatible with major pipettesFilters reduce cross contamination and prevent aerosols from penetrating into the pipette, and are positioned to allow extra headspace when pipetting maximum volumeFine tip for improved accuracy and precision
