Reduce breakage and chipping of glass pipette tips with the Thermo Scientific™ Nalgene™ Polypropylene Pipette/Instrument Sterilization Tray. The horizontal design allows the pipette to be completely immersed in the disinfectant. Rigid plastic pans are stackable, lightweight, quiet, and less expensive than stainless steel. The lid fits into grooves in the pan to minimize the spillage of hazardous materials.
