If you utilize vacuum filtration for your lab research, you can't afford to jeopardize the results. To ensure accuracy, it's crucial that you take the proper steps for each test. Unfortunately, it's not always easy to remember procedures, especially when you're just starting out in the research field. To help you ensure the accuracy of your results, here are four steps you should take whenever utilizing vacuum filtration.
Test Your Vacuum System
If you're going to be using vacuum filtration, you need to make sure that the test field isn't contaminated. Unfortunately, contamination can be a big problem in a busy lab, especially where particulate matter and moisture are concerned. One way to avoid contamination is to test your vacuum system on a regular basis. The best way to accomplish that is through the use of a vacuum filter testing kit. Your testing kit will allow you to test your vacuum filter for signs of contamination, including the presence of particulate matter and moisture.
Choose the Right Filter
When it comes to working with vacuum filter systems, you need to start with the right filter. Choosing the wrong filter for your project will interfere with the accuracy of the results. This is particularly true when choosing the size of the filters to work with. Choosing the wrong sized filter for your testing needs will lead to inaccurate results. For instance, if the filter is too large, gaps can develop due to folding. If the filter is too small, holes may develop in the funnel. Both issues can cause problems with your results.
Ensure Proper Pressure
When utilizing vacuum filters during research, it's important to ensure proper pressure. To do this, you need to make sure that there's a proper seal between the flask and the funnel. If the seal isn't tight, aspiration can occur, which means the gas or liquid will filter back up through the tubes, resulting in problems with accuracy. Not only that, but your test will be contaminated, which means you'll need to start over.
Adjust for Small Samples
Finally, when working with vacuum filters, be sure to adjust for smaller samples. Using standard procedures for smaller samples can affect the overall results of your test. When working with smaller samples, use test tube attachments, rather than the standard vacuum filter flask. It's also important that you reduce the size of your filter paper when working with small samples.
