Thermo Scientific Nunc 1.8 mL externally-threaded universal tubes offer versatile storage solutions, whether used in large-scale storage systems or for traditional cryostorage in dewars. They are available in both racked and bulk formats, with options for 2D barcoded or non-coded tubes.
These tubes are designed for scalability, making them suitable for both low-throughput and high-throughput applications. They feature graduated markings and a white patch for manual labeling. Compatible with standard 10x10 cryostorage boxes, their external threading helps minimize contamination. Additionally, they are automation-pickable when used with the Universal Latch Rack.
The innovative universal cap design features a single-piece construction with a molded-in gasket, ensuring a secure seal. The cap cannot be over-tightened, whether manually or with automated capping tools. The thermoplastic elastomer gasket is designed for stability across a wide temperature range, from room temperature down to the vapor phase of liquid nitrogen.
