Profile: Detection Limits LLC is a supplier of PFA labware, PFA sample introduction systems for ICP-OES and ICP-MS, PFA bottles, and acid purification systems. Savillex PFA bottles are manufactured from the highest purity PFA resin. A proprietary two stage molding process produces a unique smooth surface finish, which reduces the possibility of trace metals plating out and being trapped on the surface. The bottles feature a wide mouth GL45 opening with unique lip design that eliminates drips, and the cap seals so effectively that no secondary seal (insert) is required. They are available in 100 ml, 250ml, 500 ml, 1 L, and 2 L sizes. The smaller sizes are ideal for making intermediate stock solutions of multi-element standards. Also 500mL size is used for storing calibration blank or diluent solutions. The 1 L & 2 L sizes are useful for supplying autosampler rinse ports with acid wash solution.
