3A molecular sieves joint purchase?

GammaFunction - 26-2-2013 at 16:50

This is a long shot, maybe won't work, but I'll try.

I wanted to buy some 3A molecular sieves. Some as drying agents, more to store with tools. Ebay doesn't have them, except for one seller in Japan.

However, deltaadsorbents.com sells them at 5 lbs for $42, 10 lbs for $60 and 25 lbs for $100.

But I'm not in mainland USA, so shipping would kill me because they don't ship USPS.

So anyone want to split an order to take advantage of bulk pricing?

(I can also trade some 22/29 and 24/40 Teflon sleeves, on the off chance you need any.)

Also, there is CRL molecular sieve for putting inside sealed windows on Amazon and ebay. The shipping charges are not great but OK for my island location.

Though they don't tell you when selling it, CRL's website says that it is a 3A sieve, but with a small 1mm grain size, unlike the big convenient pellets that the normal stuff comes in. So I'd like to avoid it.

once in a while you can find it on ebay. I did. I will try and find the order and get back with you.

This is from the UK, so the problem is exorbitant shipping charges.

Some other ebay guy occasionally sells 'ethanol grade' A3 sieves, but he seemed dodgy, seemingly catering to moonshiners/fuelmakers.

Very nice. And they ship USPS, which turns out to be more important than the actual price.

What a strange assortment of products, however.

I just yesterday got an offer from a polish company which is producing molecular sieves 3A/4A and others sizes. They want 10€ + shipping for a 5kg pack and are offering discount on bigger batches.

Shipping from Germany would be not really cheap, 45€ for 10 kg, Poland I dont know, and this would be not insured (actually unnecessary with the item I would believe).

The company has other highly interesting items too, id somebody is already selling (semi)professionally stuff on Ebay or elsewhere, then there is an opportunity here. They are starting international business just now and will be glad to get a foot in the door by any means. Prices are great.

That they are just starting is obvious when you look at their
alibaba page. But I vouch for them being real and very friendly. I have no personal financial interests here and I am not connected to them except for having bought these column fillings which are otherwise hard to get and very expensive. Here one liter of the rings 3x3mm costs me 48€ + shipping.
Gets much cheaper if you buy more. actually 1kg of the sieves costs 15€. 5kg original pack costs 10€. Its no typo, I asked.

There must be cheaper but slower ways for shipping methinks.

But actually the best, fastest and cheapest way to ship from anywhere in the world to the US is the US Army. If you would know somebody in the army with a little brain then he/she will find you the transport in no time. Without being in europe or whereever necessarely, also the army is a family regarding this, that I learned times ago.


Ok. Interested? PM me if you like, I will help to smooth things out so thats wanted.

regards

What payment methods do they accept?
Do you have an eBay link to an auction or their eBay shop?

I've sent them a message several days ago. Unfortunately no reaction...
