The founders of Penn-Century retired and closed in 2015.

Penn-Century’s patented devices are no longer available for purchase from us or any other supplier.
 
Shanghai Yuyan Instruments Co.,Ltd. now provide a self-developed MicroSprayer® Aerosolizer and High Pressure Syringe – Model YAN30012 for fast, precise, targeted, liquid aerosol doses of up to 250µl in mouse, rat or larger animals or custom applications, whitch can be used for replace Penn-Century’s Model IA-1C and FMJ-250.
 
The MicroSprayer® Aerosolizer – Model YAN30012 High Pressure Syringe permits precise administration of a wide range of pharmaceutical, biologic, radiographic and toxicologic formulations in aerosol form directly to the lungs.
 
The MicroSprayer® Aerosolizer – Model YAN30012 High Pressure Syringe is designed for fast, targeted, air-free intratracheal aerosol administration to mouse or rat. The device can be used to administer a precisely quantifiable, highly-concentrated, air-free plume of liquid aerosol directly into the lungs or other locations. It may also be used for intranasal or in vitro applications. It can aerosolize a wide range of liquids or particle solutions/suspensions, including pharmaceutical and biologic formulations, contrast/imaging agents and toxicological materials. (It does not administer dry powders.)
   
For intrapulmonary applications, the tip of the device is gently inserted down the trachea of the anesthetized anima – near to, but not touching the carina (first bifurcation). The portion that is inserted into the trachea measures 1.25″/2″.
 
. Quick, precise aerosol dosing directly to the lungs – with no waste
. Purely mechanical, air-free technology
. Uses no heat, propellant, ultrasound or compressed air. No air burden to subject.
. Unique patented design is light, hand-held, easy to use
. Rounded tip permits safe, gentle intratracheal insertion
. Fully sterilizable, autoclavable and reusable
. Delivers a far higher volume and concentration than is possible with nebulizer/inhalation systems
. Produces a far broader, more uniform distribution than liquid bolus/droplet instillation methods  
Intratracheal use of MicroSprayer® Aerosolizer：
For best results, position the tip of the device near to – but not touching the carina, or first bifurcation.
