Two different instruments of Molecular Reality Corporation have carried the name, each as the first model of the company's MR series. Both use an ESP32-S3 microcontroller and an LMP7721 amplifier chip; their designs are otherwise unrelated.

• MR1 Nanopore Reader, an open-source design for a desktop nanopore instrument, released on October 16, 2026, and in the public domain under CC0 since October 21. It was earlier called the Sentinel Nanopore Reader and Daemon Pore. Its status line reads "Designed. Simulated. Built and measured: not yet."
• MR1 Molecular Streaming Device, an earlier handheld research device about the size of a large smartphone, also called the MR1 Handheld Molecular Streamer, which the company describes as "one of several prototypes the team has built over the years"

• MR1 (gene), the human gene for the MHC class I-related protein, which presents vitamin B metabolites made by bacteria to mucosal-associated invariant T cells
