Ultra-thin wall design facilitates rapid and steady heat transfer. Smooth interior tube surface minimises binding of enzymes and nucleic acids. Raised rims of wells protect against cross-contamination and provide tight seal particularly in combination with BRANDás new sealing mats. The 40µl wells can hold sample volumes of 2µl to 30µl. This helps to reduce reagents costs and shortens cycle times. The plates can be filled using conventional multichannel pipettes or automated systems. Suitable for qPCR (quantitative Real Time PCR).
