PCR tube racks here all come from Globe Scientific and hold PCR plates, strips and tubes. 96 well work racks come five to a pack in fluorescent colors, and one set is stackable. PCR cold work racks keep samples at 4C and change color, green to yellow or purple to pink.
Cold racks keep master mix and enzymes chilled during PCR and qPCR setup, and two use an SBS / ISBER footprint. A lidded rack doubles as a microcentrifuge tube rack for 0.2mL, 0.5mL and 1.5/2.0mL tubes.
