The National Institute of Allergy and Infectious Diseases (NIAID) intends to negotiate on other than full and open competition the purchase for Leica HyD detector from Leica Microsystems, 1700 Leider Lane, Buffalo, IL 60089. (1)158004385 3151 6640 HyD RLD 2 channel for DMi8: (2) 158004259 3151 6640 External Detection Unit:  (3) 158004254 3151 6640   Blocking Filter SP800 for HyD RLD: (4) 8074321 Installation

Leica HyD detectors improve detection efficiency by 50%, rendering even very weak signals visible.  Installation of these detectors on the SP5 STED confocal will allow the instrument to be used for many new experiments for which it is currently not applicable.  Additionally, the instrument will be able to be used for live cell imaging which requires very low intensity excitation illumination. The microscope system is covered by a service agreement with Leica, and using components other than those bought from Leica will invalidate our agreement. To assure optimal performance and reliability it required a service by specially trained and experienced service engineers. All responsible sources may submit a response that will be considered. The Government reserves the right to make a decision whether this requirement is available for competition. All responses shall be submitted no later than 2:00 PM eastern standard time September 01, 2016 to Lisa Hinton 5601 Fishers Lane, Suite 3A68, Rockville, MD 20852 email, [email protected].
