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