Is the temperature measurement accuracy of PCR instrument insufficient? Tongzida Medical PT1000 ± 0.02 ℃, helps with genetic testing

In genetic testing, the temperature cycling accuracy of PCR instrument directly affects the amplification effect. It is necessary to maintain ± 0.1 ℃ accuracy in the cycle of 95 ℃ denaturation, 60 ℃ annealing, and 72 ℃ extension. Traditional sensors often fail to detect due to insufficient high-temperature stability. The PT1000 temperature sensor of Tongzida PCR instrument is specially customized for genetic testing equipment, and has become the industry benchmark with ultra-high precision and high temperature stability.

H2: Core technical requirements for temperature sensors in PCR instruments

The temperature cycling process of PCR instrument requires sensors with a wide temperature range (-50~150 ℃), high temperature stability (drift ≤ 0.05% for 1000 hours at 95 ℃), fast temperature response (≤ 1 ℃/s), and strong anti-interference ability (suitable for laboratory environment). The PT1000 temperature sensor of the PCR instrument perfectly meets these requirements with its high temperature coefficient and precision packaging process.

H2: Tongzida PT1000 overcomes three major technical pain points of PCR instrument

1. High temperature stability: Using pure platinum leads and ceramic substrate packaging, the PCR instrument PT1000 temperature sensor is stable for a long time at a high temperature of 95 ℃, with drift ≤ 0.04%, ensuring precise and controllable amplification process;

2. Rapid response capability: The thermal response time is as low as 0.3 seconds, which is suitable for the rapid temperature rise and fall requirements of PCR instruments and shortens the detection cycle;

3. Anti interference design: Shielding layer packaging technology effectively resists laboratory electromagnetic interference and ensures accurate temperature data.

H2: Research institutions have measured that the success rate of genetic testing has increased by 20%

A certain biological research institute once used imported sensors, but 15% of the detected samples failed due to high temperature drift. After replacing the PT1000 temperature sensor of the Tongzida PCR instrument, the detection success rate increased to 99.8%, and the experimental efficiency was significantly improved. The stability of sensors directly determines the reliability of experimental data, and Tongzida's products are completely comparable to imported brands

H2: Four key indicators for selecting PCR instrument sensors

H3: Temperature range: Select a wide temperature range of -50~200 ℃, covering the entire PCR process;


H3: High temperature drift: prioritize models with ≤ 0.04%/1000h to avoid frequent calibration;


H3: Response speed: ≤ 0.5s, suitable for fast temperature rise and fall requirements;


H3: Calibration certificate: A traceable calibration certificate is required to meet the requirements of scientific research data.
