Hey there! As a supplier of deep well plates, I often get asked whether these plates are suitable for storing biological samples. Well, let’s dive right into it and explore the ins and outs of using deep well plates for sample storage. Deep Well Plate
First off, what are deep well plates? They’re basically multi – well plates with deeper wells compared to standard microplates. These plates usually come in different well numbers, like 96 – well, 384 – well, and even 1536 – well formats. The depth of the wells can range from a few millimeters to over a centimeter, which gives them a larger volume capacity.
One of the big advantages of using deep well plates for storing biological samples is the high – throughput aspect. If you’re working in a lab that deals with a large number of samples, say in genomics research or drug discovery, deep well plates are a godsend. You can store a whole bunch of samples in one plate, which saves a ton of space in the freezer or storage area. For example, in a 96 – well deep well plate, you can store 96 different samples side by side. This is way more efficient than using individual vials for each sample.
Another plus is the compatibility with automated systems. Most modern labs use automated liquid handling systems to process samples. Deep well plates are designed to fit these systems perfectly. The robotic arms can easily pick up and dispense liquids into the wells, which speeds up the sample handling process. This not only saves time but also reduces the risk of human error.
Now, let’s talk about the material. Deep well plates are typically made from polypropylene. Polypropylene is a great material for storing biological samples because it’s inert. It doesn’t react with most biological substances, so it won’t contaminate your samples. Also, it has good chemical resistance, which means it can withstand exposure to a variety of chemicals that might be used in sample preparation or analysis.
Temperature stability is also crucial when it comes to storing biological samples. Deep well plates can handle a wide range of temperatures. They can be frozen at ultra – low temperatures, like – 80°C, which is common for long – term storage of biological samples such as DNA, RNA, and proteins. And they can also be used at room temperature or even in incubators at higher temperatures for short – term storage or sample processing.
But it’s not all sunshine and rainbows. There are some potential drawbacks to using deep well plates for sample storage. One issue is the risk of cross – contamination. Since the wells are close together, there’s a chance that a sample from one well could spill over into another well, especially if the plate is not handled carefully. This can be a real problem, especially in sensitive research where accurate sample integrity is crucial.
Another concern is the evaporation of samples. The relatively large surface area of the wells in deep well plates can lead to evaporation, especially if the plates are stored for a long time without proper sealing. Evaporation can change the concentration of the sample, which can affect the results of subsequent experiments.
To address these issues, there are some solutions. For cross – contamination, you can use well – designed sealing mats or caps. These can prevent any spillage between wells and keep the samples isolated. And for evaporation, you can use sealing films that are specifically designed to reduce evaporation. Some of these films are even breathable, which can prevent condensation inside the wells while still minimizing evaporation.
In addition, proper labeling is essential. You need to clearly label each well with the sample information, including the sample ID, date of storage, and any other relevant details. This helps to avoid mix – ups and ensures that you can easily identify and retrieve the samples when needed.
So, are deep well plates suitable for storing biological samples? The answer is a resounding yes, but with some caveats. They offer a lot of benefits in terms of high – throughput storage, compatibility with automated systems, and material properties. However, you need to be aware of the potential issues like cross – contamination and evaporation and take appropriate measures to address them.
