Key Considerations When Choosing a PCR Machine for Labs
Selecting the right PCR machine for diagnostic labs requires careful evaluation of several factors. Here’s what to look for:
1. Throughput and Sample Capacity
High-throughput PCR machines are ideal for laboratories processing large volumes of samples daily. Consider the sample capacity of each laboratory PCR machine—benchtop PCR machines may offer 48 to 384 wells, while modular systems can be scaled up for even greater capacity.
When preparing samples for high-throughput PCR, having the right centrifuges is essential to ensure efficient separation and processing. For more on this topic, check out our Centrifuge Buying Guide and Portable vs. Benchtop Centrifuges.
2. Portability and Space Requirements
If you need flexibility, a portable PCR machine or compact PCR machine is a great choice. These models are designed for point-of-care testing, mobile labs, and facilities where space is at a premium. Benchtop PCR machines, on the other hand, are best for permanent laboratory installations.

3. Speed and Efficiency
A fast PCR machine can significantly reduce turnaround times, which is crucial for clinical diagnostics and urgent testing scenarios, such as PCR machines for COVID-19 testing. Evaluate the thermal cycler’s run time and cooling technology to ensure it meets your workflow needs.
Sample preparation often requires homogenization of tissues or other materials. Explore our range of homogenizers to optimize your nucleic acid extraction process. For more insight, see Best Homogenizers for Food Science and Biotech Labs.
4. Accuracy and Sensitivity
PCR machine accuracy and sensitivity are vital for detecting low-abundance targets and ensuring diagnostic confidence. Look for machines with advanced heating technology and uniform temperature control to support precise results.
Accurate measurement of reagents and samples is critical for reliable results. Equip your lab with precision balances to support your PCR workflows.

5. Automation and Software Integration
Modern PCR machine equipment often includes automation features and software integration. Features like touchscreen displays, automated sample loading, and connectivity with laboratory information systems can streamline your workflow and reduce manual errors.
6. Maintenance and Service
For clinical and diagnostic labs, minimal maintenance is a plus. Some PCR machines are engineered to require less frequent servicing, which is especially valuable for remote or high-throughput settings.
Types of PCR Machines for Diagnostic Applications

- Real-time PCR machines: Also known as quantitative PCR (qPCR) machines, these allow for real-time monitoring of amplification and are widely used in diagnostic labs.
- Digital PCR machines: Offer high precision and sensitivity, ideal for applications requiring absolute quantification.
- Thermal cyclers: The core of any PCR machine, thermal cyclers control temperature cycles to enable DNA amplification.
For safe and contamination-free PCR setup, consider working within a biosafety cabinet, especially when handling clinical or infectious samples.
