如果测试失败：
1.应确认：
◦TVK校准是最新的。
◦探头无破裂或损坏。
2.在棉签上滴2-3滴矿物油。用棉签在每个探头的圆锥表面涂上薄薄一层油，改善热量传递。
3.重复 多探头温度验证试剂盒使用指南(https://tools.thermofisher.com/content/sfs/manuals/4460108A.pdf)里“运行96孔仪器测试之前”的步骤。
4.应确认：
◦探头牢固固定在合适的检测孔里。
◦电缆与端口牢固连接。
◦带状电缆平放在热熔保险器下方并且无折叠。
◦加热盖关闭并锁住。
5.重复 多探头温度验证试剂盒使用指南(https://tools.thermofisher.com/content/sfs/manuals/4460108A.pdf)里“运行测试”步骤。
请注意，如果检测再次失败，请发送邮件至instrumentservices@thermofisher.com联系Thermo Fisher Scientific。

带有96孔（快速与标准）模块的Veriti热循环仪拥有创新的VeriFlex模块用于增强PCR功能。六个独立的Peltier模块提供最大的配置多样性和灵活性，并提供两个关键优势：
1.PCR条件优化：每一模块均可单独设置一个特定温度，非常适合用户在PCR条件优化过程中对温度进行精确控制。
2.运行更多实验条件：六个Peltier模块也可用于在同一反应中设定六个不同的退火温度。
Auto Delta特性能够帮助您在循环阶段中逐渐增高或降低每一循环某一步骤的温度。其中一个常见应用就是降落PCR（touchdown PCR）。

The heated thermal cycler lid is designed to make sure that optimized pressure is applied on the microplate for an efficient PCR reaction. When using PCR tubes, excess pressure on the tubes, from the heated lid can cause deformation of the tubes. To avoid this, we recommend using the Tray/Retainer set, as shown below:
Cat. No. 4381850, MicroAmp 96-Well Tray/Retainer Set for Veriti Systems – This Tray is for use with MicroAmp Strip Tubes (or MicroAmp Reaction Tubes without Caps, 0.2 mL), with the Veriti Thermal Cycler, SimpliAmp Thermal Cycler, and Proflex PCR System.
Cat. No. 403081, MicroAmp 96-Well Tray/Retainer Set – This Tray is for use with MicroAmp Strip Tubes (or MicroAmp Reaction Tubes without Caps, 0.2 mL), with the 7000 System, 2720 Thermal Cycler, and GeneAmp PCR System 9700.
Cat. No. 4379983, MicroAmp 96-Well Tray for VeriFlex Blocks – This Tray is for use with MicroAmp Strip Tubes (or MicroAmp Reaction Tubes with Caps, 0.1 mL), with the Veriti Thermal Cycler, Veriti Fast Thermal Cycler, SimpliAmp Thermal Cycler, and Proflex PCR System.
Please take a look at this video: How to Use Adapter Tray Retainers in Thermal Cycler Starter Kits (https://www.youtube.com/watch?v=1uh2ZxZJtgs).

If the test fails:
1.Verify that the:
-Calibration of the TVK is up-to-date.
-Probe tips are not cracked or damaged.
2.Dispense 2 to 3 drops of mineral oil onto a cotton swab. Use the swab to apply a thin film of oil to the cone surface of each probe to improve heat transfer.
3.Repeat the steps in “Before You Run 96-Well Instrument Tests” from the Multiprobe Temperature Verification Kit User Guide (http://tools.thermofisher.com/content/sfs/manuals/4460108A.pdf).
4.Verify that the:
-Probes are seated securely in the appropriate test wells.
-Cables are connected securely to the ports.
-Ribbon cable lies flat under the thermal cutout and is not crimped.
-Heated cover is closed and locked down.
5.Repeat the steps in “Run the Test” from the Multiprobe Temperature Verification Kit User Guide (http://tools.thermofisher.com/content/sfs/manuals/4460108A.pdf).
Please note, if the test fails again, contact us at instrumentservices@thermofisher.com.
This can happen if the wrong plastics are used, or if the tubes are not being used with the correct tray/retainer set. Check the manual for directions on appropriate loading of the sample. Also, you can check for compatible plastics from here (https://www.thermofisher.com/us/en/home/life-science/pcr/pcr-plastics.html).

The Veriti Thermal Cycler with a 96-well block (Fast and Standard) features innovative VeriFlex Blocks for enhanced PCR functionality. Six separate Peltier blocks provide maximal versatility and flexibility and offer two key benefits:
1. PCR optimization: each block can be set with a specific temperature, which is ideal for precise control over PCR optimization.
2. Run more experiments: the six Peltier blocks can also be used to run up to six different annealing temperatures in the same run.
The AutoDelta feature allows you to incrementally increase or decrease the temperature or hold time with each cycle for a given step within a cycling stage. One common application for this is touchdown PCR.
The 96-Well Block has a 3.9 degrees C/sec max block ramp rate, the 96-Well Fast Block has a 5.0 degress C/sec max block ramp rate, the 384- Well Block has a 3.7 degrees C/sec max block ramp rate, and the 60-Well Block has a 3.3 degrees C/sec max block ramp rate.
The plates and plastics will be specific to the block type. Choose the appropriate block type below for a list of the compatible tubes, plates, and films.
-Veriti 60-Well
-Veriti 96-Well 0.1 mL
-Veriti 96-Well 0.2 mL
-Veriti 384-Well
The Veriti Thermal Cycler is available in four formats:
Veriti 96-Well Thermal Cycler (a 0.2 mL or 0.1 mL)
Veriti 384-Well Thermal Cycler
Veriti 60-Well Thermal Cycler
Veriti 96-Well Fast Thermal Cycler
The recommended conditions are determined to ensure no static discharge (low humidity) occurs.
Recommended Conditions:
- Veriti: 20-80% humidity
- VeritiPro: 15-80% humidity
We have not tested Veriti and VeritiPro thermal cyclers in low humidity, below 20%, therefore we cannot recommend using them in those conditions.

There is no universal ramp rate for a thermal cycler because both the block and sample ramp rates are different for each thermal cycler. The sample ramp rate changes with the volume of the sample since more time and energy are required to heat higher sample volumes. The ramp rate may also need to be changed for a particular PCR assay or primer pair if you are trying to use the same PCR assay on two different thermal cyclers, for example.
As a reference, the block ramp rate commonly used with DreamTaq Polymerase on the MiniAmp thermal cycler is 3.0 C/sec. In a 50 µL PCR reaction, this translates to a sample ramp rate of ~1 C/sec.
