Advantec Polypropylene Filter Holder for 47mm Membranes, 1/pk, 43303020

I use it to filter small amounts of wine for lab analysis. I hate the single use membranes because they don't filter much volume, 47 mm gets me all I need. The Advantec is the same as comprable units for a quarter of the price.

Bought this for building a Silt Density Index tester. It works as well as expected and have had no issues with the connections to it or its seals.

Excelent

great price.

There is something suspicious about this product. The add on Amazon's page says cost is $37.42 ($7.20 / 10 items), and further down, in specifications, it says Number of items 52. HOWEVER, the site of the manufacturer has the same price for ONE SINGLE UNIT of this product... My guess is the add in Amazon is wrong and misleading... how can they offer 52 units for the price of 1??? I would appreciate a clarification from Amazon...
