Common questions

Where do you ship, and what does it cost?
Across the EU, insulated and tracked, dispatched from within the Union. Free over €150; below that, a flat €12.99. The batch reference travels on the packing note, and the certificate reference with it once a certificate exists for that batch.
Can I return an order?
Your statutory right of withdrawal applies. It does not extend to sealed items whose seal has been broken, because those cannot be returned to stock. The full terms are in the right of withdrawal notice.
What exactly am I buying?
Laboratory reagents supplied for in-vitro research use only. Not for human or veterinary use, not food, not cosmetics, and not medicinal products. We sell to research professionals and institutions, and you confirm that at checkout.
Who manufactures the material?
We do not publish that, and this site used to. Sourcing that is published is sourcing that is copied, which is why almost nobody in this category discloses it. What replaces it on a listing is the specification: CAS number, sequence, molecular formula and molecular mass, each with the date it was recorded from a primary source. Where that source is a public chemical registry the page links it, so the figure can be checked without taking our word for it. Where it is a manufacturer’s own specification sheet, the page gives the date and not the sheet.
Do you tell me what these compounds do?
No. Listings carry specification, provenance and assay data. Where a compound has a research literature, we link to it and let it speak for itself. We are not permitted to characterise these materials any further and we are not going to imply it sideways.

Ordered on a Tuesday, the parcel was in Munich by Thursday. Tracking worked the whole way.

M. KellerMunich, DE

Plain box, correct invoice, no drama at customs. Exactly what it should be.

S. LindqvistUppsala, SE

Asked a question about storage conditions before ordering and got a plain, sourced answer the same day — not a sales pitch.

J. van der BergUtrecht, NL

Fast dispatch to Vienna, and the bundle price matched the arithmetic on the product pages to the cent.

K. BergerVienna, AT

Second order. Same packaging, same turnaround, same paperwork. Consistency is the review.

P. JansenAntwerp, BE

I compared five EU storefronts for documentation before ordering. This was the only one where every identity figure carried a source and a date. That decided it.

Dr E. FarkasBiochemistry dept, Budapest

Emailed to change the delivery address an hour after ordering. Fixed within the afternoon, confirmed in writing.

C. DuboisBrussels, BE

Stock levels on the site were accurate; nothing on my order went missing or on backorder after payment.

H. SørensenAarhus, DK

Their FAQ answered the payment and shipping questions honestly enough that I did not need to contact support at all.

G. NovakLjubljana, SI

Parcel to rural Ireland in five business days, tracked the whole way. No complaints.

D. O'BrienCo. Galway, IE

The specification page listed the CAS number, sequence and mass with sources and dates before I asked. That is the level of documentation I wish every vendor treated as normal.

Dr A. NowakCell biology lab, Kraków

The concentration calculator with the printable per-graduation table saved me a spreadsheet. Small thing, kept me on the site.

T. MoreauLyon, FR

Vials arrived exactly as photographed, labels legible, batch details on the paperwork. Reordering was two clicks.

Materials group, LeipzigDE

What convinced me was the quality page saying plainly what they do and do not publish. No inflated promises, just the record. The order itself was uneventful in the best way.

L. ContiBologna, IT

The listing said 2–5 business days to Spain and it was four. Tracked door to door.

R. OrtegaValencia, ES

Checkout was clear about VAT and shipping before the payment step, not after. Appreciated.

N. KowalczykWrocław, PL

The vials match the catalogue photography exactly — same label, same format. Sounds trivial until you have received enough parcels where it does not.

F. MeierZurich, CH

Straightforward. Ordered two reagents, both arrived within the stated window, sealed and cold to the touch, paperwork complete.

A. FerreiraPorto, PT

The restriction notes on the product pages are unusually direct for this category. I would rather buy from a shop that states them than one that hides them.

Dr I. PetrovaAnalytical chemistry, Sofia

Every question I had before ordering was already answered somewhere on the site — the spec table, the quality page, the FAQ. The order matched the listing exactly. That is the entire job, done properly.
