Profile: United Scientific Products, Inc produces & supplies pipette tips, microtubes, PCR tubes, tube racks and lab gloves. All of our pipette tips are developed using the highest quality virgin polypropylene available in the industry and molded to exact standards to ensure precise measurements. Our complete line of pipette tips includes standard or beveled, smooth or reference lined, regular and small orifice, flattened gel loaders, as well as barrier filter pipette tips. Our PCR tubes are designed for optimal fit with all leading thermal cyclers. The thin tube walls accelerate heat transfer which provides shorter cycle times. Our 64-well freezer rack works with most cryovials and screw cap tubes. Each well is alpha-numerically coded, so that samples can be transferred without confusion.
