Pipette Tips deliver high performance with exceptional value. A perfected balance between raw materials and efficient manufacturing process results in superior low retention. Pipette Tips are universal fit and compatible with major pipettes. Pipette Tips have smooth, hydrophobic surfaces to ensure accurate pipetting. Filters reduce cross contamination and prevent damaging aerosols from penetrating into the pipette, and are positioned to allow extra headspace when pipetting maximum volume. Molded volume reference markings offer a quick double check opportunity. Hinged lids on rack are designed for easy one-handed opening, making it easier to access repeatedly. Lids have stacking feature for added stability and a secure locking tab. Lightweight lid design prevents tipping when open. Interior support ribs prevent racks from warping. RNase/DNase free and non-pyrogenic. Every case is printed with the lot number for quality traceability. Packed sterile, 96 tips/rack, 960/case.
