Folks,

I was looking for propionic acid (both to make esters/perfumes and to use as a solvent in nitrosations) and I found this website:

https://www.laboratoriumdiscounter.nl

I saw this website mentioned once in this section, but without any opinion. Has anyone already ordered anything from them? Any experience with delivery delays or purity of reagents? They don’t seem to be too costly, and have a fair range of alcohols/organic acids, which is nice to prepare esters.

Thanks!

They ship fast and have good prices, especially on their own brand chemicals.

I have ordered two times from them and my experience was good. Fast shipping and decent prices. I only ordered from their own brand chemicals (copper sulfate, hydrochloric acid 37%, sodium chlorite, potassium hydroxide, potassium chloride). Nothing really special, just replenishing stocks with cheap replacements. Purity of the materials is good.

Quite a few chemicals, however, are not shipped to private persons (e.g. nickel salts, cobalt salts, chloroform).

Ok, thanks a lot! I don't intend to buy anything fancy from them, just a couple of alcohols and organic acids and things of that ilk.
Basic stuff, the same as you. Thanks for the advice. Dank U veel!

labshop.nl is also a good shop for basic things. I would try to compare the prices but they are quite different - some things a more expensive, some things are less. The assortment is a modest one but the strong point is that usually everything is at home by the next day.

Their website is in Dutch only?

Yep, this is a usual thing for the internet shops here. The exceptions are extremely rare.
They speak English quite fluently by phone & email.

Agreed, but that doesn't make navigating the thing any simpler. By chance, German serves quite a lot, when you have learnt what the correspondances between Dutch (~ Platt Deutsch) and German (~ Hoch Deutsch) look like…

Well, my native language is Russian (also I can easily understand many eastern-european), so on this basis I can compare Dutch, German and English chemical nomenclature unbiased. And I would say that the Dutch looks quite OK for me, but German and English names for compounds look quite strange. (These unique names for elements like Sodium, Potassium, Tungsten in English for example, and when I try to search compounds on es-drie (it also only in German) web site I feel lack of a true gothic keyboard).

Of course German was an official language of chemistry in the past, so the most texts will be never translated, and now this is my motivation to study German - otherwise I think my knowledge of chemistry will never get a good basis.

But Dutch shops are easy to navigate for me - if I need Natrium I go to letter N.

Coming from French, English and German names are pretty familiar to me, but neither are Natrium, Kalium or Wolfram. Anyways, the differences are minor. French has also 'azote' instead of nitrogen. Anyways, thanks for the tip!

Apfelsäure, Schleimsäure... *cough*

Strange, I just got told about this shop very recently, and was astonished about the cheap prices for certain solvents.
Also, I got told it is a fine supplier.

Haven't ordered yet, but the damn prices!
Absolutely great!

Tsjerk - 3-8-2021 at 13:44

Also a nice supplier, just be a bit careful when ordering chemicals they label is possible drug precursors, you might have to explain what you are planning on doing with them. Also some chemicals require an end user statement.

Fyndium - 3-8-2021 at 14:13

It is good chemistry knowledge to be informed of common alt names, at least for the most common stuff, like potassium(kalium), sodium(natrium), tungsten(wolfram), etc.

Whatever, copy-paste it to google and it will likely give you a lot of hints what it is better known to you.

draculic acid69 - 3-8-2021 at 16:40

Looked at the site and clicked on the letter P and first thing that I can see is palladium so I click on it and there is some very expensive palladium powder that looks very black.
My palladium powder is still a dull grey. I don't think it is supposed to be as dark
as it is in the picture . Then I clicked on propionic acid and it says €8 for a litre.
That sounds very cheap. I do not think I could buy it from China for that price. Then I clicked on acetic acid and its more expensive than the propionic acid then I clicked on platinum and for Pt powder there was the same black charcoal powder picture they had for Pd powder. These are what I would think are red flags usually but there's ppl above in the post saying that they have successfully ordered from there before so maybe they are all good.
Also if anyone wants platinum or palladium I can beat there prices by a lot. U2u for details if interested

Google has whole website translation while you use it, even easier. I have used it on Russian forums, even the posts are very readable that way.

metalresearcher - 3-8-2021 at 22:38

Site looks nice, but they are more expensive than Onyxmet.

And under 'Elements' there are some errors: https://www.laboratoriumdiscounter.nl/en/chemicals/elements/

wrong symbols for two elements. F = Phosphorus, Pd = Lead ???

teodor - 4-8-2021 at 01:39

Some hint. When I need to know the name of a compound in different language I just go to wikipedia on this language (let say, wikipedia.de) enter the compound formula (let say, H2SO4), press "search" and then I get the compound article with the name as a title (Schwefelsäure).

Fyndium - 4-8-2021 at 02:11

In wiki, you can also just move your cursor over different languages and see the name of the page.

There are also some details of interest in different language, for example I like to check German wiki because sometimes it has some nice data about compounds and reactions that English doesn't.

I’m not sure I'd judge the purity of a powder out of a picture. There are too many parameters that can go wrong in colour rendition for it to be a good tell-tale of quality. Besides, it might just be a generic picture – spilling out platinum or palladium powder just to take a picture is taking a risk of losing some, to quite an appreciate financial loss.

Properly what I wanted. I’m pretty happy with their prices for propionic acid and isopropyl alcohol that I use for household cleaning, too.

Obviously they are no chemist's, phosphorus in Dutch is fosfor. Maybe the also have wrong pictures for some of their compounds, for example the palladium.

I got a bottle of their barium hydroxide, I believe the label said it was the octahydrate, and when I obviously used too much it turned out be the monohydrate, while the CAS number was for the anhydrate...

Fyndium - 4-8-2021 at 07:46

Reference pictures are just.. reference. Any white, grey or black powder will look just like that, same goes for any colorless liquid. Easier to just leave the pics off, because no one really cares about looking at those.

But messing up with hydrates and CAS numbers is a more serious matter in my books.

I agree. I've ordered a couple of commonplace chemicals. I’ll see what I get. Thanks for your inputs.

Tsjerk - 4-8-2021 at 11:03

Ah, I just checked that bottle, the CAS was correct for the monohydrate label, but it turned out to be the octahydrate...anyway, it was mislabeled.

Order placed on the first of June, called on the 13th to say hello and get to know them.
I was told my order would leave the next day as they were waiting on ampoules.

Today is 7th of July, my order hasnt been shipped yet.

I'm pissed off and pretty sure I wont ever do business with them if they actually manage to ship me my order someday.

I don’t think they should be held responsible. Frankly, delays have increased exponentially lately, and so did lead times. I had to wait quite a lot for my bottle of phosphorus pentoxide. It came from Roth. When I checked on the Roth website, directly, I saw that the lead time wasn't even available.

There’s shortage of everything these days. Now, what I do is ask them beforehand what they do have in stock in a list of reactants I want, and more or less tailor my orders to fit their own supplies. That way, I don’t have to wait.

Herr Haber - 7-7-2022 at 06:48

In the meantime I dropped a message on their chatbot and got a tracking number.
I hope their packaging is good. Those 144 ampoules were not cheap !

Tsjerk - 7-7-2022 at 07:03

Their packing is OK. I also got to know their shitty "yes, we are shipping tomorrow" which actually means next month. But in the end they ship...

Actually they even send me some items that were on backorder twice... The first time I got a package out of the blue. Normally they send a tracking number when actually sending something. Two weeks later I got a tracking number for the same parcel. I thought it was probably a late processing of the first order or something. But the next day I actually got the package a second time....

I didn't tell them, if they would have perfect spot-on customer service every time I probably would. But they even screwed me by combining two orders and then delaying the one order with the item of the separate order... So no, this double delivery is mine.

I don't know how easily deoplosmiddelspecialist sends abroad, and they also put items on backorder, but at least they ship what they have got and don't delay the complete order because one item is not available.

Laboratoriumdiscounter is quite good to my opinion. I wrote a review about that shop and gave them 7 out of 10 points and told that if things were organized better, then they would get 9 or even 10 points. The quality of their products is good, or sometimes even excellent. One of my recent orders contained HBr 48% for a very competitive price and the liquid really is clear, just a very very pale yellow, when you are looking through a liter of liquid in the long direction of the bottle. I have had HBr 48% before from other sellers and the liquid I obtained always was looking like piss. I have similar experience with their CuSO4.5H2O and their DMF. No smelly shitty half-decomposed stuff, but nearly odorless, perfectly colorless.

I placed several orders. With two of them, I had to wait and send reminders, or I received a partial shipment and had to wait a long time for the remaining part. The other orders just went fine, I received them in two days. I told them in my review, that it is my impression, that if things go according to the standard order handling process, then things are fine, but if an exception occurs somewhere in the process, then their organization is not prepared to handle the exception in the right way. They must improve that. I received a positive response to my review and they admitted that things could be improved. Since then, I already ordered two times again (one order of DMF and methanol, and some pyridine and diisopropyl ether), and both orders went smoothly.

I also have good experience with deoplosmiddelspecialist. They even sell 30% NaClO3 (solution in water). This is within EU-regulations, but allows hobbyists to obtain pure chlorates at a decent price. I intend to use it for experiments in making perchlorate of it by means of electrolysis. Unfortunately, deoplosmiddelspecialist hardly ships anything abroad. Only really innocuous things are shipped abroad. Inside the Netherlands they ship nearly everything for very reasonable shipping costs. Only some items need ADR-shipping, e.g. NaBH4.

Keras - 7-7-2022 at 23:17

To top it up with their slightly messy way to handle things, I happened once to order calcium hypochlorite and received potassium nitrate instead. Since ordering KNO₃ requires normally an EUA, I was happy to keep it and just ordered calcium hypocrite again, which I received fine at the next shipment.

They must be quite a few working there, and they have considerably expanded their offer, which inevitably leads to mishaps and blunders. The non-chemical stuff they sell is not as attractive, though. Some items are fairly priced, but most of them are very dear, even by ‘current’ standards.

All things considered, a normal experience so far.
Everything you mentioned: from "yes we ship tomorrow" to having to wait a month wondering if anyone has seen my order I have experienced personnally from several big lab suppliers. It's *not* a Laboratoriumdiscounter thing only.
Sometimes I've received a little bit more (actually, everyone from whom I bought 2.5 liters of anything ended up sending me 3x1l. Shame, I could reuse 2.5l jugs for liquid waste.)
Other times I received the wrong items, partials were sent without notice (up to 4 for 1 order from my main supplier but they know me best). When I order several size HDPE jars with inner lids and caps and all 3 arrive in separate parcels I wonder what kind of dope their logistics department runs on ! :mad:

But back on the order. I assume they didnt ship because some chemicals were missing. And... uh... 10 disposable scalpels. I couldnt have thought these would be on backorder :)
The missing chemicals are quite common so a bit of a suprise aswell. Oh well, I can do with alternatives for a while.
As Tsjerk said, the packaging is OK. Actually, I would call that excellent and it's one of my main criteria when I decide if I want to continue working with a supplier.
My next order will include ADR and a couple of "intent of use" (for acetone ? really ?). I guess I'll see how they deal with that.
I was surprised the 0.5L THF was sent in an UN HDPE bottle instead of a metal can (and no ADR though the same amount of diethyl ether would be). I know these things are sturdy but against THF ?
I'm thinking about repackaging this to an Al bottle.

Agree with your ratings and reasons Woelen. I would compare them to APC Pure (UK) I saw you mention their HBr but already have a little bit. Enough for the little bromate I have.
Not nearly enough to fill 144 ampoules with bromine :)

Those 10ml ampoules are just beautiful, excellent, perfect quality. Thinking about all the possibilities I now have makes me giddy. Displays, gifts, pre-weighting sensitive chemicals... Oh, that's gonna be fun !
Price is high but it'll save so much time, hazards, thinking over test tubes that It's a non issue.
But all that will have to wait ! Vacation time next week !
