The Low Diffusion PE Liquid Scintillation Counting Vial carries a micron thin PTFE®-type coating on the inside surface, reducing the diffusion of classical type solvents. The cap is lined with aluminum foil as a barrier. The Low Diffusion PE Vial was developed for long term low level measurements as a cost effective alternative to very expensive PTFE counting vials
PerkinElmer offers high quality glass and plastic vials. The best vial to choose is dependent on the type and volume of sample to be counted and the cocktail that will be used.
幸运8平台彩票Plastic vials are injection (blow) molded to exacting specifications from virgin high-density (linear) polyethylene (HDPE). Caps are recessed to assure reliable loading and transferring in automatic sample changers without skipping or jamming. Since polyethylene vials are produced from petrochemicals, they contain no measurable background and are preferred for low activity counting applications.
For over 50 years PerkinElmer has been a leading supplier of radiochemicals, liquid scintillation cocktails, vials and nuclear counting detection instruments. Today is no different. We have always been committed to providing you products for all of your radiometric needs and we are still committed today.
