My orders are failing but my card is showing a charge?

You may be entering the wrong address without even knowing it. Our payment processor uses AVS (address verification) for all charges and will refuse a charge if you enter the wrong billing address.

Sometimes the address that the bank has on file is a variation of your actual address. Even cards that normally pass AVS might fail our processor’s particularly strict AVS. If you have tried multiple variations of your address without success, please contact your bank and check to see which address they use for validating credit cards.

Keep in mind that the bank may have both a mailing and a billing address on file for you. Please be sure that you are entering the correct billing address.

Each time you submit a transaction and use the wrong address, YOUR bank will put a hold on the card/funds to cover the transaction, but since your address does not match we reject that transaction. YOUR bank may hold your funds up to 30 days, normally they are released within 3-5 days.

Even if stored properly, research chemicals are known for falling out of suspension. This can be easily fixed by running the chemical under hot water and shaking lightly.

A research chemical I ordered shows distinct separation – why is this?

Chemicals are not suspended unless they are water soluble. Shake rigorously and the precipitate will disperse back into the solution. Apply gentle heat.

What are you research chemicals suspended in?

Polyethylene glycol (PEG) 300.

What kind of glassware do you use for your peptides?

The ideal container for peptide manipulation should be clean, chemically inert and optically clear & strong.

We pride ourselves in only using high quality specialty glassware to inhibit the adsorption to surfaces which would grossly distort subsequent results.

What is the proper storage and shelf life on your research chemicals?

We recommend storing out of direct sunlight, at room temperature and avoiding any fluctuations in humidity. By conservative estimates, this should prevent any degradation for several years.
