Statutory Authority: This acquisition is conducted under the authority of the Federal Acquisition Regulation (FAR) Part 13—Simplified Acquisition Procedures, Subpart 13.106-1 (b) (1), Soliciting from a single source and is not expected to exceed the simplified acquisition threshold. Contracts awarded using FAR Part 13—Simplified Acquisition Procedures and at a dollar value less than the simplified acquisition threshold are exempt from the requirements of FAR Part 6—Competition Requirements.

This notice of proposed acquisition is posted as an intent to award a FFP contract on a non-competitive basis to VWR International LLC to purchase the objectives, condenser, and fluorescent LED cubes for the REVOLVE R4 Upright & Inverted Capability microscope.
Background/Description of Requirement

This acquisition is being conducted under Federal Acquisition Regulation (FAR) Part 13 - Simplified Acquisition Procedures, and FAR Part 12- Acquisition of Commercial Items, and the resultant contract award will include all applicable provisions and clauses in effect through Federal Acquisition Circular 2023-05 dated September 7, 2023.

The National Institute on Aging (NIA), Laboratory of Genetics and Genomics (LGG) owns a Revolve Microscope Echo and require the components and objectives. This Microscopy has been a cornerstone of scientific exploration for centuries, enabling researchers to observe and analyze intricate structures at the cellular and subcellular levels. The REVOLVE Echo Microscope provides exceptional image clarity and resolution, allowing users to observe samples at the cellular and even subcellular level. The microscope is equipped with multiple imaging modalities, including brightfield, darkfield, phase contrast, and fluorescence microscopy. This versatility allows users to examine a wide range of specimens and adapt the imaging technique to suit specific research needs. With advanced technology for live-cell imaging, the REVOLVE Echo Microscope enables researchers to study dynamic processes in real-time. This is particularly valuable for understanding cellular behavior, cell interactions, and various biological mechanisms. Motorized turret accommodates up to four LED Light Cubes (DAPI, FITC, TEXAS RED and Cy5) which have exceptional performance in capturing images with 5 MP monochrome sCMOS camera and no darkroom required during visualization. Different optics helps to visualize cultured cells, nuclei, and others. The in-built intelligent Nosepiece informs software which objective is in use. 

Salient characteristics:

CUBE4001/DAPI: DAPI emits blue fluorescence when bound to DNA, and it is used to visualize cell nuclei.

CUBE4002/FITC: Fluorescent dye in molecular and cell biology experiments. FITC emits green fluorescence when excited with a specific wavelength of light.

CUBE4004/TxRED: Designed to excite a red-fluorescent dye called TxRED for visualization and analysis of fluorescently labeled samples.

CUBE4005/CY5: Designed for excitation (EX) and emission (EM) of a cyanine dye called CY5.

Objective 10X Fluorite PHS NA 0.30 10 mm: 10X (10 times magnification), Fluorite lens, which is a type of optical glass used to reduce chromatic aberration and improve image quality.

Objective 40X Fluorite PHS NA 0.75 0.51 mm: 40X (40 times magnification), Fluorite lens for improved image quality and reduced chromatic aberration. Numerical Aperture (NA): 0.75, indicating a higher light-gathering and resolving ability compared to the 10X objective. Working Distance: 0.51 mm, indicating a shorter working distance, which may be suitable for specific applications. Application: Suitable for higher magnification imaging and detailed examination of specimens.

Objective 4X Fluorite Phase NA 0.13 17 mm: Magnification: 4X (4 times magnification). Lens Type: Fluorite lens for reduced chromatic aberration. Numerical Aperture (NA): 0.13, which suggests a lower resolving power but a larger field of view. Working Distance: 17 mm, providing a significant distance between the objective lens and the specimen. Application: Potentially used in phase contrast microscopy for low magnification examination.

Objective 20X Fluorite ELWD NA 6.6-7.8 mm: Magnification: 20X (20 times magnification). Lens Type: Fluorite lens designed for enhanced image clarity. Numerical Aperture (NA): Range of 6.6-7.8 mm, suggesting good light-gathering capability. Working Distance: Variable, ranging from 6.6 mm to 7.8 mm, which can be helpful for imaging thicker samples. Application: Likely used for higher magnification imaging with increased working distance.

SCND1001/ELWD Universal Condenser: Designed for use with objectives that have longer working distances and potentially suitable for phase contrast or brightfield microscopy.
