Pipette Tips deliver high performance with exceptional value. A perfected balance between raw materials and efficient manufacturing process results in superior low retention. 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 max volume. 200¿L filter tip is longer than standard tips for better access to vessels & increased headspace to filter. Molded volume reference markings offer a quick double check opportunity. Hinged lids on rack are designed for easy one-handed opening, have stacking feature for added stability & a secure locking tab. Lightweight lid design prevents tipping when open. RNase/DNase free and non-pyrogenic. Every case is printed with the lot number for quality traceability. Packed sterile, 96 tips/rack, 960/case.
