Perfect Seives, Resuable as well. Great value.
These sieves are a godsend, after having to deal with counterfeit ones before it's nice to see a good product. these sieves pass the hand test, two or three balls on your hand wet with a single drop of water will sizzle and get noticably warm in your palm. regenerating them is as easy as a little ceramic crucible and a microwave on medium setting, stir every 30 seconds to a minute to vent moisture, wear gloves they get hot. Don't let them get too hot though. I got 10 re-generations out of a batch before I accidentally scorched them while working. you could possibly get more uses out of a batch, however you get a good value for your money.

Amazing!
These molecular sieves are amazing! Leaps and bounds better than plain silica gel. Perfect for 3D printer filaments.

Gutes Produkt schlecht geliefert.
Als die Molekülarsiebe endlich bei mir angekommen sind (ohne zu klingeln vor die Haustür geschmissen wurden) war die eigentliche Verpackung schon kaputt und die Perlen waren großteils in der Tüte/Verpackung. Zum Glück hatten die Molekülarsiebe aber noch nicht so viel Wasser gezogen und wahren für mich, nach umfüllen, noch brauchbar. Sonnst kann ich mich bis auf den Staub bei der erstn Nutzung über nichts beschweren. Ich habe die Perlen genutzt um von meinem Lösemittel den Wassergehalt zu reduzieren. Hat gut funktioniert.
