looking to complete my hobby lab and have found a seller who sells also the more "advanced" reagents and solvents.
He has not everything from my "wish list" and not always the amount I was looking for but some good stuff indeed.
Would you say the pricing is ok?
Names are in German on the list, so please forgive my laziness to translate everthing correctly), prices are converted into EUR, amounts in g,kg or
ml, l.
The bromine seems ridicuolusly cheap, but it's only technical grade as he noted. Otherwise most should be lab or even reagent grade.
Also he mentioned that the Hydroflouric Acid is brown. Anyone have a clue? Haven't found a hint what that could be. Maybe it was used for rust removal
and it is Ironoxide contamination? I guess I have to ask for that once more.
Thank you in advance. woelen - 11-2-2015 at 00:04
In general, the pricing of these chemicals is very good, or even ridiculously cheap. E.g. 500 g sodium for EUR 27 or so is fantastic. The list also
contains some very hard to obtain items, such as PCl5.
I would take everything from this list, except the HF. Do you really want dirty brown 70% HF around in your house? Please stay away from that if you
value your health. You certainly don't want to distill this to make it pure again.
If the bromine is low grade, no problem. Distill it. Bromine is very easy to distill if you have glass apparatus, I have done several times. It is
fantastic to have 500 ml for that price, even if it is impure.

At those prices you should buy two of everything and stock my lab too. ;-)
Seriously, those are some serious chemicals at fantastic prices. I have to concur with woelen on all points.Amos - 11-2-2015 at 06:17
I think I might need to move to Germany...Loptr - 11-2-2015 at 07:20
I just had a friend that moved to Germany because his wife is in the military. I might have to get him to do some shopping for me.

Thank you very much for the input.
To set the record straight, actually it is in Poland. I live not far away from the Polish border.
As for the HF I will reconsider, knowing how dangerous HF is. I already have some 20% solution, also technical but clear. Nevertheless I'll ask him
what this contamination is just out of curiousness.
Also thanks for the tip with the bromine. Of course I have good ole German Schott NS29 destilling equipment.
P.S. Make no mistake, without proper contacts most hazardous chems are very hard to get in todays Germany too. Conc. H2SO4 or reagent grade HNO3 65%
are no problem at all here. Red phosporous and iodine neither. But benzene for example is nearly impossible to get without contacts for normal
citizens.

Germany is going to restrict the 65% nitric acid at some point as it
is an EU directive. I would assume Poland will too, unless both
countries say this doesn't make sense and thumb their nose at the
directive.Schleimsäure - 11-2-2015 at 12:45

Yes, I read about that EU-directive which is already effective in GB. Read also that Germany makes an exception here, can not find the link. I can
still order 1l of reagent grade 65% HNO3 for EUR 10,99 in Chemnitz/Germany. 5l for EUR 47. Of course circumstances are probably subject to change,
that's why I already accumulated some liters.

So I sent the final order list. Unfortunately he mistook PCL5 for P2O5. So I'll only get the P2O5 which is one of the more expensive items.
But anyway, 800 EUR (700 USD) for all this is still good. To the members here, who asked per PM, I will ask him in two weeks, if he ships amounts up
to 10 kilos.
