Tips For Selecting A Digestion Block For Your Lab

Selecting the right digestion block for your sample preparation creates a strong foundation for long-term accurate and precise analysis. A range of digestion blocks are available in the market today, each with different features, benefits, and drawbacks. So, how can you determine which system is the right fit for your lab?

Here are some tips to help you navigate the selection process and choose the best digestion block for your needs.

1. Consider your throughput: Determine the number of samples and the sample size you will be processing on a regular basis. If you have a high sample throughput, you may need a digestion block with a larger capacity to accommodate multiple samples simultaneously. If your lab is running multiple sample sizes, a system with modularity or configuration flexibility could be helpful.
2. Define your temperature requirements: The maximum temperature capability of digestion blocks varies. Ensure you select a system that can operate within the temperature range needed for your samples. Additionally, look for a digestion block that offers temperature uniformity of +/-1.5°C or better. Uniformity describes how consistent the temperature is across the block surface. Lower variance of temperature means that samples are all being exposed to the same heating profile which is essential for the reproducibility and accuracy of the sample preparation process.
3. Durability: Since digestion blocks are used with high heat and often corrosive acids, it's important to select a model that is stable in these conditions. Look for digestion blocks constructed from durable and chemically resistant materials to ensure longevity and safety.
4. Understand programmability: The amount of programmability needed for a lab is influenced by the experimental methods in use as well as internal quality programs and industry regulations. To help determine the right functionality for you, consider the following questions: Do your methods require more than one temperature? Do you need the ability to control the temperature ramp? Does your industry or quality program require the ability to view or store experimental data?
   
   If you determine that you need a system with more complex controller functions, look for one with an intuitive and user-friendly interface to simplify operation and minimize the learning curve for laboratory staff.
5. Safety features: Prioritize safety features such as automatic shut-off or visual/audio alarms to prevent accidents and ensure the well-being of laboratory personnel.

By considering these factors and conducting thorough research, you can make an informed decision when selecting a digestion block. Always remember to prioritize quality, safety, and functionality to ensure the smooth operation of your laboratory processes.
