Compresstome Vibrating Microtome System VF-800-0Z

The National Heart, Lung, and Blood Institute intends to issue a sole-source purchase order to Precisionary Instruments, LLC for one Compresstome Vibrating Microtome System VF-800-0Z, with responses due by September 9, 2026 at 12:00 PM EDT. The procurement carries a sole-source justification centered on the device's patented Auto Zero-Z technology, which eliminates Z-axis deflection to produce smooth, structurally intact precision-cut lung slices from delicate human fibrotic explants; standard microtomes cause severe tissue damage on irreplaceable clinical biospecimens.

The system will support translational research into pulmonary fibrosis pathobiology, molecular assessment, drug testing, and biomarker discovery across fibrosing lung diseases. The Compresstome enables tissue slicing from 40–2,000 micrometers with 1-micrometer resolution and supports up to 10 days of viable pharmacologic testing essential for drug screening. The acquisition includes the VF-800-0Z Vibrating Microtome, Starter Kit VF-800 Domestic, Gooseneck LED Sample Visualization Lamp, and virtual training and demonstration support. Delivery is required to Room 8S205, 10 Center Drive, Bethesda, Maryland 20892. The procurement is conducted under FAR Subpart 12.102(a) for commercial products. Responses must include unit price, list price, shipping and handling costs, delivery period, prompt payment discount terms, F.O.B. point, UEI, TIN, and business size certification. All offerors must maintain active SAM registration. NAICS code is 334516 (Analytical Laboratory Instrument Manufacturing) with a small business size standard of 1,000 employees. The Government reserves discretion to proceed on a non-competitive basis or conduct competitive procurement based on responses received.
