Selecting a Dialysis membrane | soma das | 2010-11-24 | Click here to register. |

| My desired compound has a molecular weight of 1986 and its spherical dimension is 1.1 nm. I am searching for membranes and found the: Biotech Dialysis Tubing (Cellulose ester with a MWCO of 500-1000). But am worried since the size of my molecule is very small, it may pass through the pores. In the pore size chart the lowest pore size is 10 nm!!! How can I find a ten times smaller pore size? | | |

 | The pore size chart is to be use for general reference, 10nm is roughly about 100kD MW. Spectrum makes a CE membrane with a MWCO of 100-500D. Please contact Spectrum's customer service at customerservice@spectrumlabs.com for a sample to test with your compound. |
