Patent number: 9737891Abstract: A thermocycling device and method of operating a thermocycler instrument, the instrument including a sample holder, at least one thermal cycling element, and at least one first and second temperature sensors, for causing the sample holder containing the at least one sample to undergo polymerase chain reaction amplification by repeated cycling between at least a denaturation heating stage and an annealing cooling stage. The first temperature corresponding with the temperature of the sample holder is monitored using the at least one first temperature sensor, and a second temperature corresponding with the temperature external of the sample holder is monitored using the at least one second temperature sensor. Based upon the first temperature and the second temperature, the power that is delivered to the at least one thermal cycling element of the instrument is dynamically controlled.Type: GrantFiled: May 31, 2012Date of Patent: August 22, 2017Assignee: STRECK, INC.Inventors: Joel TerMaat, Scott E.

Publication number: 20170065971Abstract: 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.Type: ApplicationFiled: June 30, 2014Publication date: March 9, 2017Inventors: Matthew R. Kreifels, Scott E.

Patent number: 8889086Abstract: An improved tube including a closure portion, a strap integrally connected to the closure portion and being configured for defining a living hinge, a body portion having a longitudinal axis and an outer wall generally circumscribing the longitudinal axis, and being integrally and hingedly connected with the closure portion by way of the strap. The body portion including a sample portion being generally elongated along the longitudinal axis and being configured for elastic deformation along a portion of its length, including in a direction that is generally transverse to the longitudinal axis so that at least a portion of the wall structure compressively and resiliently deforms and engages a wall defining an opening in a sample block of a polymerase chain reaction amplification device, and the first outer wall dimension of the sample portion reduces to a smaller second outer wall dimension.Type: GrantFiled: April 20, 2012Date of Patent: November 18, 2014Assignee: Streck, Inc.Inventors: Hendrik J.
