Caution: 1. It is forbidden for user to open the case and check by oneself in warranty period.
Please contact supplier or manufacturer in time if any failure needs to open the
case to check.
2. Since temperature control characteristics (rate of temperature rise/fall, stability,
fluctuation and etc.) of different brands and each instrument are specific, and
biotic experiment itself has uncertainty and vulnerable to outside influence, PCR
program that runs well on one instrument might fail to reach same effect on
another. Therefore, please adjust PCR running program to get ideal performance
once instrument is changed.
