1. The MicroSprayer® Aerosolizer and Dry Powder Insufflator™ and other accessories of Penn-Century are designed for pre-clinical in vivo and in vitro research.  Our hand-held aerosol devices are custom-made to order and are based on patented technology. We are not aware of any comparable handheld atomizer for precise intratracheal administration of liquids or dry powders in aerosol form.
  2. Our devices are very different from one another.  The liquid MicroSprayer® Aerosolizer is air-free and Dry Powder Insufflator™ is air-driven.  Each model type is based on very different operating principles, methods of use and requirements for cleaning.  If you have had previous experience with other atomizer devices, that is no guarantee of correct use of these devices.
  3. Each model of our devices requires specific instructions and accessories that we provide when the devices are sold to assure correct and proper use and maintenance.
  4. As manufacturers, we have no way to validate the condition of devices after they are sold or analyze what materials were used in the device.
  5. Our devices have been cited in more than 1,500 peer-reviewed publications and drug patents using a very wide range of pharmaceutical, biologic or toxicological materials.  Researchers use our devices to develop new therapies and vaccines, as well as to create models of infectious or genetic diseases, or toxicological models of exposure to environmental, occupational or biowarfare agents.
  6. If our devices are not properly used, cleaned or stored, they may contain residue from prior use that may be hazardous to subsequent users, or contaminate the results of subsequent research. 
  7. In addition, in order for our devices to work properly, the user must carefully follow the manufacturer’s instructions for proper handling, operation, cleaning and storage.   If that has not happened during previous use, it is likely the device will not work properly. 
  8. If essential accessories are missing, or parts of the device are blocked, worn or damaged, it is not possible to achieve the precise results that the devices were designed to obtain.
  9. If you are using borrowed or previously used devices of Penn-Century, make sure you look closely at the Product Descriptions and Instructions for Use for those devices on our website.  If possible, try to determine the date of purchase, how the devices were used, with what materials, and how they were cleaned.
  10. Ultimately, the end user must apply the same vigilant attention to the condition and care of their Penn-Century equipment as they do to all other aspects pertaining to the integrity of their scientific inquiry.


  1. Penn-Century was founded in 1985.  Throughout our history, we have remained the exclusive manufacturer and supplier of our technology.  We are not aware of any other comparable hand-held precision device for intratracheal aerosol administration.
  2. From the beginning, our precision aerosol devices and laryngoscopes have been exclusively made in our manufacturing facility in Pennsylvania (USA) under consistent and rigorous quality controls.
  3. Our methods of manufacturer are complex and highly specialized.  During our history, we have never assigned them to another manufacturer.

Note: The MicroSprayer® Aerosolizer and Dry Powder Insufflator™ are patented devices of Penn-Century, Inc.  Their design and their names are protected by international patents and trademarks.  Unless a public announcement is made by us concerning the sale or transfer of our technology, buyers should assume that any devices that bear our name that are sold after January 2016 by anyone other than Penn-Century, Inc. have either been previously used or were not manufactured by Penn-Century, and are purchased at the buyer’s risk.
