Why You Should Use a Biometra T-One Thermal Cycler

Thermal Cycler

A thermal cycler sometimes called a PCR machine or DNA amplifier, is an essential machine in biochemistry labs. They are used to facilitate temperature sensitive reactions. In molecular biology they are used for DNA sequencing, cloning, generation of probes, quantification of DNA and RNA, studying patterns of gene expression, and detection of sequence-tagged sites. They are most often used however to amplify segments of DNA via the polymerase chain reaction (PCR) and also used in restriction enzyme digestion and rapid diagnostics.

Description of a Thermal Cycler

The top or front of the device has a thermal or heating block with holes where test tubes or other sample vessels, holding the reaction mixtures are inserted. The thermal cycler then raises and lowers or cycles the temperature of the block in distinct, pre-programmed steps. For reactions to work properly, the block must change temperature at exact times, and spend exact durations of time at precise temperatures. The scientist programs the temperature cycling information into the thermal cycler either by computer or via a console on the instrument, or uses a pre-programmed routine built into the machine.

High quality units like the Biometra T One Thermal Cycler are equipped with a heated lid that presses against the lids of the reaction tubes. This prevents condensation of water from the reaction mixtures on the insides of the lids. They also have silver blocks to achieve fast temperature changes and uniform temperature throughout the block. And finally, they have multiple blocks with high heat capacity, each of which is kept at a constant temperature, and the reaction tubes are moved between them by means of an automated process.

When a lab is seeking to purchase thermal cyclers, there it must consider its current and future needs. Key questions include:

  • Types of PCR protocols used
  • The level of sensitivity required
  • The number of samples to be amplified at one time
  • The range of sample volumes (analytical to preparative)
  • Trade-offs between yield and specificity
  • Whether gradient capability is required
  • Protocol run times (e.g., for fast PCR)
  • The number of users

A wonderful choice that will fit the above requirements is the Biometra TOne Thermal Cycler. Economical, quiet in operation and high-performance, Biometra TOne Thermal Cyclers are ideal for complex PCR optimization and routine lab work.
