300Microns

300MICRONS is a specialized tools and consumables company focused on the high-growth 3D cell culture market. Its core technology involves microscale thermoforming of thin, transparent polymer films into microwell arrays with unique round bottoms, which can be further functionalized with pores or surface modifications. The company serves both academic and industrial customers in drug discovery, toxicity testing, and tissue engineering through standard products and custom OEM solutions. As a private SME, it operates in a competitive but expanding niche critical for advancing more physiologically relevant in vitro models.

Proprietary microscale thermoforming of thin polymer films to create microwell arrays for 3D cell culture. Platforms can be functionalized with ion track-etched micropores, nanotopographies, and adhesive patches to control the cellular microenvironment.

Competes in the 3D cell culture consumables market against giants like Corning (Elplasia plates), Merck (Ultra-Low Attachment plates), and Greiner Bio-One, as well as specialized firms like MicroTissues (now part of Sigma-Aldrich) and Insphero. Differentiates through its unique round-bottom, ultra-thin film design and exclusive porous microwell technology.
