The Biomeme Pre-Filter Pack consists of 30 1mL syringes and 30 syringe driven pre-filters. Choose from 1, 50 and 300 μm (micrometer) filters to meet your application needs.
In general, if your sample prep column clogs, we recommend using a finer pre-filter pore size. If the pre-filter clogs, we recommend using a larger pre-filter pore size. You can also use these pre-filters in succession (i.e. stepping down).
1μm: typically used for fine particulates (e.g. silty water, homogenized soil)
50μm: typically used with eDNA samples (depends on the body of water being sampled)
300μm: typically used for fibrous homogenates (e.g. leaves, plant matter)
If you are still struggling to determine which pre-filter is best for your use case, you can email firstname.lastname@example.org or try our Pre-Filter Variety Pack.
To use the column filters, draw your liquid sample into the provided 1 mL syringe, install the pre-filter onto the syringe tip’s luer lock, and then slowly push down on the syringe plunger to filter your sample into the punctured hole of your Biomeme M1 Sample Prep Cartridge.
