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 retention Pipette Tips have smooth, hydrophobic surfaces to ensure accurate pipetting Multiple 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 vessels 200μL filter tip is longer than standard tips for better access to vessels and increased headspace to filter Pipette 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 pipettes Filters reduce cross contamination and prevent aerosols from penetrating into the pipette, and are positioned to allow extra headspace when pipetting maximum volume Fine tip for improved accuracy and precision Molded volume reference markings offer a quick double check opportunity
