Improved sample tube with transparent tip having particular utility for nucleic acid amplification

摘要: An improved sample tube that includes a body portion having longitudinal axis and wall generally circumscribing the axis. The terminates in distal tip dimple. at least one transparent (e.g., tip) is adapted for transmitting light. wail configured elastic deformation along feast of its length, including direction transverse to axis, so it compressively resiliently deforms engages defining an opening block PGR amplification instrument. may be made by injection molding polymeric material thermoplastic.
