Labcon SuperSlik® Protease Free Pipette Tips
SuperSlik® Low Retention tips have a proprietary modified polypropylene surface that limits the adhesion of cells, rDNA, proteins, and other viscous materials. Their accuracy and precision is up to 10 times better with viscous samples than standard non-wettable polypropylene. SuperSlik® tips are made from our own proprietary resin formulation that uses no additives or coatings that migrate into your samples. Unlike low retention tips from many others, SuperSlik® tips use no restricted chemicals and meet RoHS regulations. The resin helps increase the contact angle of fluids and lets you dispense the maximum amount of sticky DNA molecules. These tips were developed in our own laboratory and have been found to be ideal for viscous samples. Low retention tips are best suited for pipetting thick or sticky fluids and may not be appropriate for all uses.
Bulk Pack
Tips are supplied in one large bag inside a corrugated container. These are not recommended for long-term storage due to warping.
