In laboratory experiments, precision and accuracy are key to obtaining reliable results. Well plate templates, especially for 96 well plates, are vital tools for organizing samples, reagents, and controls. However, even seasoned researchers can make simple mistakes when using these templates, leading to costly errors and compromised data.
In this article, we will explain the common mistakes researchers make when using well plate templates and offer practical advice on how to avoid them. Even if you are conducting high-throughput screening, PCR, or ELISA, this guide will ensure you optimize your workflow and avoid the pitfalls that could hinder your experiment’s success.
What is a Well Plate Template?
A well plate template is a standardized map used in laboratory experiments to organize samples in a multi-well plate. The most common type is the 96-well plate, which contains 8 rows (labeled A–H) and 12 columns (labeled 1–12), resulting in a total of 96 wells. These templates are essential for tracking which sample goes into which well, ensuring proper organization and preventing mix-ups.
Key Uses of Well Plate Templates:
- Sample organization: Helps scientists keep track of each sample and its corresponding data.
- Consistency in experiments: Ensures that all experimental variables are correctly placed in designated wells.
- Reproducibility: Accurate templates allow others to replicate the experiment using the same setup.
Researchers use templates to design their experiments, ensuring that each well is filled with the appropriate reagents, samples, or controls. The template’s map enables easy referencing during the experiment and when analyzing results.
Why Well Plate Templates are Crucial for Laboratory Accuracy
| Mistake Name | Description of Error | Experimental Impact | Prevention Tip | Relevant Application (e.g. HTS, PCR) | Corrective Action (Inferred) |
| Mislabeling Wells | Incorrectly labeling a well or recording the wrong sample in a specific well position. | Leads to invalid experimental results due to untrackable samples and loss of data integrity. | Double-check well labels before starting and use automated software or digital templates to track them. | HTS, PCR, ELISA | Re-map data by cross-referencing remaining sample volumes; repeat the assay if data-to-sample integrity is lost. |
| Incorrect Plate Orientation | The well plate is not aligned correctly with the template (e.g. rotated 180 degrees). | Risk of misplacing samples and reagents, leading to cross-contamination or missing data points. | Verify plate orientation using visual checks or automated software to ensure alignment before loading. | HTS, PCR, ELISA | Identify true orientation via asymmetrical plate markers and computationally rotate the data map if the error is consistent. |
| Edge Effects | Samples in the outermost wells behave differently than those in the centre of the plate. | Inconsistencies in data and uneven results due to temperature gradients or evaporation variations. | Use buffer/media-filled wells at the edges and optimise incubation conditions for even temperature distribution. | HTS, PCR, ELISA | Apply statistical correction factors to edge wells or exclude edge wells from the final dataset during analysis. |
| Overloading or Underloading Wells | Failing to load each well with the precise required volume of liquid. | Overloading causes overflows; underloading results in weak reactions, failed assays, or inaccurate results. | Use calibrated pipettes, follow volume control guidelines, and use templates that include volume markers. | HTS, PCR, ELISA | Normalize data against a reference control or discard wells where overflow/evaporation compromised concentrations. |
| Failing to Update Templates | Using outdated templates that do not reflect changes in protocols, reagents, or sample sets. | Leads to confusion, errors in sample tracking, and lack of consistency across experiments. | Regularly update templates to ensure they remain aligned with current experimental goals and new protocols. | HTS, PCR, ELISA | Manually audit experimental notes against the template used and update the digital record to reflect actual protocols. |
| Using Wrong Plate Type or Format | Using a template that does not match the physical plate format (e.g. using a 96-well template for a 24-well plate). | Mismatch in experimental needs and volume requirements, leading to organizational failure. | Confirm the plate format (e.g. 6-well, 24-well, 96-well) matches the requirements before selecting a template. | HTS, PCR | Transfer samples to the correct plate format if stability allows, or restart with a compatible template. |
Without a well plate template, it would be easy to misplace samples, confuse wells, or skip essential controls. The accuracy of laboratory experiments depends heavily on correctly labeling and placing samples in their respective wells. Well plate templates eliminate these risks by providing a visual map to guide the placement of samples and reagents.
For example, when performing high-throughput screening, where hundreds of samples may be tested at once, well plate templates become indispensable. They ensure that each well is correctly filled, reducing the chances of human error. Similarly, in PCR or ELISA, where sample placement is critical for accurate readings, templates are vital for avoiding costly mistakes.
Benefits of Well Plate Templates:
- Reduces the chances of human error
- Increases experimental reliability and reproducibility
- Saves time and effort by providing a clear, organized structure
Common Mistakes When Using Well Plate Templates
Mistake 1: Mislabeling Wells
One of the most common mistakes when using well plate templates is mislabeling wells. Since most experiments involve placing multiple samples in different wells, incorrectly labeling a well can lead to disastrous consequences. If the wrong sample is placed in a well that is recorded incorrectly, the entire experiment’s results may be invalid.
Mistake 2: Incorrect Plate Orientation
Another common mistake is using the wrong orientation for the well plate. If the plate is not aligned correctly with the template, you risk misplacing samples and reagents. This can lead to cross-contamination or missing data points.
Mistake 3: Overloading or Underloading Wells
Accurately loading each well with the right volume is critical. Overloading or underloading wells can lead to inaccurate results. For example, too much liquid may cause wells to overflow, while too little liquid may result in weak reactions or failed assays.
How to Avoid These Well Plate Template Mistakes
Tip 1: Double-Check Well Labels and Orientation Before Starting
The first step to preventing mistakes is to verify everything before you begin. This includes checking the well labels and confirming that the plate is oriented correctly. Use both visual checks and automated software to ensure everything aligns perfectly. In labs that conduct high-throughput screening or large-scale experiments, this step is crucial to avoid major errors later on.
Tip 2: Use Automated Templates for Accuracy
Digital well plate templates can help prevent common errors like mislabeling or misplacing samples. By using software to generate and track templates, you can automate many of the processes involved in sample organization.

Tip 3: Use Volume Control Tools and Guidelines
Accurate volume control is essential for experiments. Many templates now include volume guidelines, or you can use tools to ensure each well receives the correct amount of liquid. Ensuring that you use a calibrated pipette and adhere to the proper volume for each well is essential for accurate, reliable results.
Tip 4: Verify Plate Type and Format Before Use
Well plate templates are not one-size-fits-all. Different experiments require different plate formats, such as 6-well, 24-well, or 96-well plates. Before using a template, confirm the plate format matches your experiment’s needs. For example, high-throughput screening often requires 96-well plates, while PCR experiments might use 24-well plates.
