HPLC filters are used to remove impurities from solvents before they enter the chromatography system. The filtration is important as it avoids clogging the HPLC columns. They are crucial in pharmaceutical and biochemical labs for drug analysis and protein purification.
When selecting a lab pressure filter, there are certain features that one has to consider. Here are the important features.
The precision level will depend on the type of filter that is being used. For example, membrane filters have finer pore sizes than ceramic filters. This is allows them to provide more accurate filtration for delicate applications. On the other hand, ceramic filters are more suited for heavy-duty processes. They can withstand higher pressures.
Lab pressure filters are mostly made from stainless steel, ceramics, polymers, or glass. Stainless steel filters are often used for high-pressure applications. This is due to their durability and resistance to chemical corrosion. Note that steel filters do not degrade under extreme temperatures. On the other hand, ceramic filters are more effective in filtering very fine materials.
The maximum pressure can vary greatly depending on the lab pressure filter model. For example, many membrane filters can operate up to 5 bars of pressure. Meanwhile, high-pressure filters can withstand more than 50 bars. One should consider the pressure requirements of their specific applications. Always choose a filter that can handle the necessary pressure range without risk of failure.
The filtration area of these pressure filters is closely related to their efficiency. Larger filtration areas provide higher flow rates and are more efficient in long-term use. However, in this case, size does matter. The filtration area should be large enough to handle the volume of liquid one filters. It should also fit into the available lab space. Membrane pressure filters usually come with small filtration areas. These filters are ideal for micro-scale experiments.
Automatic filters are equipped with self-cleaning features. This saves one a lot of time during maintenance. That’s one of the reasons why techs prefer filters with easily replaceable components. These kinds of filters are often crucial in laboratories. This is because they reduce downtime and labor costs.
