LIVERMORE, CA, MARCH 11, 2026 -- FormFactor, Inc., a leading semiconductor test and measurement supplier, today introduced the Flatiron Dilution Refrigerator, a new benchtop millikelvin platform designed to simplify sub‑kelvin optical and electrical measurements and accelerate quantum device development, characterization, and chip-scale validation. The Flatiron enables researchers and engineering teams to perform millikelvin experiments in a compact, lab‑ready system that integrates easily into modern laboratories, reducing experimental overhead and time‑to‑data for both research and industrial quantum technology development.

Traditional dilution refrigerators often require large lab footprints and time‑consuming disassembly to change samples or reconfigure experiments, slowing research cycles and increasing the cost of testing. The Flatiron Dilution Refrigerator addresses these challenges with a novel horizontal benchtop architecture that provides ergonomic sample access, faster sample exchange, and easier integration with optical tables and standard lab equipment. By enabling frequent thermal cycling and rapid experiment iteration, Flatiron supports rapid hardware validation and characterization without the long cooldown cycles of full-scale systems, delivering faster insights at sub‑kelvin temperatures.

The Flatiron Dilution Refrigerator’s key features include:

• Millikelvin performance in a benchtop system, reaching base temperatures down to ~30 mK for advanced quantum device and materials measurements
• Faster time-to-data through a horizontal benchtop design with quick, top-plate sample access, eliminating the need to remove multiple vacuum cans and radiation shields
• Easy lab integration with a compact footprint of approximately 150 cm x 80 cm, designed to fit alongside optical tables and standard laboratory equipment
• Integrated optical access via four cryogenic windows, supporting optical and electro-optical measurements at sub-kelvin temperatures

“Millikelvin measurements are critical not only for fundamental research, but increasingly for fast, cost-effective validation of quantum hardware,” said Thomas Fries, Vice President and General Manager, Emerging Growth Business Unit at FormFactor. “With Flatiron, we make sub-kelvin measurements easier to access, easier to integrate into existing labs, and ready for industry use. The result is a benchtop platform that supports the rapid iteration and throughput required for modern quantum technology development and provides this growing industry with valuable tools for building out the ecosystem.”
