Micronic ULT & High-Density Racks

The Micronic ULT series, including the 24-1, 24-2, 24-4, and 48-well racks, is designed for ultimate precision and long-term use in cryogenic storage facilities. The Twist-Lock system prevents tube rotation during capping, while the robust polycarbonate build ensures stability under extreme conditions.

For higher throughput, the Micronic 138-2 HD Rack features a honeycomb design that stores up to 43% more samples than standard racks, the ideal choice for labs that need efficiency without compromise.

Eco-Friendly Racks

Leading the way in sustainable labware, the Micronic EFC Refill Rack and EFC Rack RM are made from 99% renewed or recycled materials, offering an eco-friendly and cost-efficient solution. The EFC Refill Rack allows reuse of the base and cover, reducing material consumption and lowering the carbon footprint by up to 69% compared to traditional racks. Both racks are ACT label certified, ensuring verified environmental performance and full automation compatibility.
