PVDF (polyvinylidene fluoride) is a hydrophobic, solvent resistant membrane that exhibits low levels of UV absorbing extractable.
PVDF is useful for HPLC sample filtration, as well as general biological filtration.
PVDF is considered to be one of the low protein binding membranes.
PVDF membranes are not recommended for use with acetone, DMF, DMSO, or bases >6N.

Amtast provides full line of Syringe Filters, if you are new to choose the filters, better to check following questions then choose the proper filters.
If you are still not sure, email us then we choose for you.
1. Compatibility. What kind of solution to filter?
2. Filtration area. The volume of sample to be filtered?
3. Pore size. Sterile filtration or particle removal? Target size?
4. Hydrophilicity & hydrophobicity. Can filter be wetted with the solution or solvent?
5. Sterilization method. Which method do you prefer? EO, gamma radiation or autoclave?
6. Inlet/outlet connection types. Which connection fit? FLL/MLS or MLS/MLS or FLL/MLL?
7. Dimension. Does the filter dimension match?

Das sind die günstigsten Spritzenfilter, die ich finden konnte. Benötigte die 0.22µm Porengröße. Verwende die Spritzenfilter für Behälter mit Nährlösung bei der Pilzzucht, die bei 120°C sterilisiert werden müssen. Das mache ich im Schnellkochtopf. Die Filter überstehen dabei 2 Stunden Kochzeit völlig schadlos. Kaufempfehlung.

Used for LC jars for pleurotus mushrooms. An 1/8" brad point drill worked perfectly to drill nice burr-less holes.1 week after sterilisation they're still clean and ready for some pleurotus mycellium! They've been sitting in an infrequently lit, mildly damp (~45% RH) "cold storage" area under our patio (more like 85°F storage with the heatwaves) to test how well they keep out contaminants.Very happy with the results!Arrived quickly and I bought the larger 25mm size for the larger potential air exchange area.

I like the idea of the product but it wouldn't suction right most of the time and it would bend the needle on the syringe. Maybe a video tutorial would help solve some issues.

Die Filter sind gut druckbelastbar und haben eine relativ hohe Filterleistung. Preis/Leistung ist Okay. Ich würde sie wieder kaufen.

Utiliser pour filtrer des e-Liquides, c'est efficace, mon eLiquide est devenu translucide sans plus aucune matière en suspension mais cela à été très long à passer (1/2h pour 10ml). Un filtre s'est envolé car je l'avais mal serré sur la seringue, il est préférable, mais pas obligatoire, de prendre une seringue avec un mini pas-de-vis comme sur ma photo, toutes n'en ont pas, j'en ai utilisé une de 5 ml qui permet de bien le bloquer en faisant un quart de tour, mais du coup j'ai trop forcé sur le piston et l'un a explosé en deux sous la pression, donc attention à bien les fixer, et ne pas appuyer comme une brute. Les seringues à embout "ordinaire" fonctionnent aussi, mais il faudra le tenir si vous êtes obligé de forcer.La partie reservoir est transparente, avec une graduation circulaire, qui nous permets de voir aisément le taux de remplissage du filtre.

Fast delivery, worked perfectly. High quality plastic casing, each filter identical and really well put together. Filtered solution 100% as expected.
