Laboratory Equipment Suppliers Help
Hi all,
My first post and I'm struggling to find decent glassware suppliers at reasonable prices.
Any pointers please anyone? Any help would be much appreciated.
Thanks

I remember some venn diagram like this: you can only pick 1 from good and cheap. Impossible to have both in real life.

I will give you a condensed version of the many many threads here:
It goes without saying that SAFETY IS FIRST. Make damn sure you know what you're doing and buy the protective gear first, before you buy the glass.
Get good quality and comfortable googles and use them EVERY TIME. If you don't have to be told to take off the googles because you are so used to them
being there, you aren't wearing them enough. Same applies to gloves: before you so much as sit on the stool the gloves need to be on. Wash your damn
hands!!! I could spend 10 pages here yelling at you to make safety first and it wouldn't be enough. Don't think it can't happen to you: it will. The
only thing you can do is make sure you are protected and that you know what to do in the case of an accident. SAFETY FIRST!!
Chinese glass : use name branded glassware. Sellers like Deschem, Laboy, Nanshin sales and Synthware are known good glass brands.Kantuu200 was a good
seller but I don't know if they are still selling.
US brands like Pyrex,Kimble, Ace, Chemglass, Wilmad labglass, are the gold standard. Chemglass tends to be thicker than other brands so heating and
cooling need to be done slower. Avogadro's on eBay is a great seller as well. You are not going to get the finest ground joints but they will work for
general & non extreme preparations. I wouldn't trust them blindly for things like distilling mercury metal, but it is possible.
Used glass can be great (see the thread from Dr. Bob "Science equipment looking for a home") but carries risks. Bruised glass is a real threat and
it can't be seen with the naked eye. Chips are a nuisance, and for the most part getting cracks repaired is not an option unless you have a scientific
glassblower available.

It is amazing we all survived befor half the crap was even invented.
Just make sure glass is borosilicate, all ways heat and cold test with water, then dry heat stress it, by then if it will break it'll do it in a
harmless fashion. 1H in the library will save you 4 in the lab.
I recommend Daschem fast shipping, great entry level quality thus far, I have distilled sulfuric acid several times from his gear.
Never fear chemicals, respect them but don't fear them, and if you do fear them don't play with them till it is gon as some one scared is dangerous.
when you respect them and know how to handle them you will rarely ever need to wear an environmental suite behind a blast shield to measure out some
kno3.
Back in the day we "Ghasp" Handled Mercury, could by a ton of stuff over the counter and safety what? Yet we're all alive. This obsessive fear culture
I loath as it actually makes it more dangerous in the trades!
Just understand the stuff which you use to the point you have healthy respect for it and no fear of it, and have a clear head and be methodical, be
prepared for accidents.
Use what is needed, as the saying goes use the tools the job demands and no more, other wise you just end up cluttered and hampered from a fast
response.

Hi thanks for the replies and comments on safety and glassware brands. I only knew of Pyrex as a decent brand so Funjerman23 thank you and thank you
for the idea of the Venn diagram fusso lol.
I'd like or should have perhaps mentioned I am studying chemistry and biology but this has come as a complete career change from IT because I started
basic home chemistry to teach my children and I fell back in love with the subject myself. It's worked as well. My eldest has moved up a set in
science and my youngest won an award from the headmaster who phoned the house personally to tell us. I personnaly am off to university next year at
the ripe old age of 40. Ish.
Rouge Rose, I have glassware I've purchased from eBay such as boiling tubes, flasks e.flasks and vacuume funnels etc. I even have a vacuum dessicator
but twice it arrived from Asia broken. Hence I could really do with a faster delivery of any kind of apparatus from the EU or preferentially UK.
What prompted me for this question was that I couldn't find any 24/29 glass thermometer wells/stems. It's not just these items it's lots.
So suggestions are welcome and those mentioned I shall checkout thanks,
ClF3

Daschem packs his stuff amazingly well, usual arrival time in Canada is 2 weeks or less some times!

In UK I have not found a better source of equipment than eBay,
new glassware from China and used Quickfit glassware within UK,
new Quickfit here https://www.scilabware.com/en/brand-group/quickfit
I suggest that you pay a little extra and purchase glassware with ground joints for future flexibility,
Erlenmeyer/Round-bottom/Flat-bottom flasks and ,if applicable ;
side-arm test tubes, funnels, filter funnels, ... almost anything with a hole in it.
Jointed glass thermometers are lovely but unless you are lucky, they are horrendously expensive.
I was lucky and bought one from a member, two are still available I believe
https://www.sciencemadness.org/whisper/viewthread.php?tid=98...
There are thermometer pockets/adapters/wells available via eBay uk at the moment.
I bought used Quickfit rather than new cheap-Chinese thermometer pockets - for better sealing joints.

I can also recommend Scientific Glassware Laboratories for new high-quality UK-made glassware.

These suggestions are great, thank you for your input you're a good bunch ![:)](./images/smilies/smile.gif)
I'll reference these next payday for a good shop around.
The only problem with the Chinese gear, for example is my £123 vacuum dessicator that arrived damaged and totally imploded at 50 KPa though they said
it was rated to 6 KPa. It's the back and forth wait you see of returns and replacements etc.
Anyway you've all answered my questions kindly and thoroughly so thank you and I look forward to my next shop hooray!

I don't follow this. At eight times (approximately) the rated pressure the desiccator failed? Would this not be unsurprising?
Although I have issues with various items of Chinese gear, I have generally (but not always) had satisfactory resolutions to my complaints to the
venders.

I know the pain they have caused all too well. I didn't know anything about the OP, and for years we would get preteens& teenagers here who where
eager, but careless, so a little of that old habit showed in my writing. Back a few years ago Bfesser would have linked to all the good threads here
on these topics but I never did get him to tell me how he had them handy. I do genuinely want to help, so please accept my apologies.

I believe that the pressure ratings are absolute,
so 50 kPa is c0.5 ATM and 6 kPa is c45 mmHg.
so about twice the force is exerted on the glass at 6 kPa compared to 50 kPa.

No problems mate, had some OH&S Twat tell me I should be wearing gloves while working a lath once asked him what is worse, a gash to a hand or a
removed hand! Problem is you got people who never touched a thing in their life making rules on what to do with them.
Just some thing that's been pissing me off more and more as of late
Respect your craft and safety will follow, they are under the delusion that if you cram more stuff on some one it will make it safer but in the end
stupid all ways finds a way!
Long story short nothing personal, cheers.

I was also looking for some glassware to update my permanent distills and the Schlenk line. The vacuum manifolds can be pretty expensive so I was
looking for a cheap vendor. I ended up ordering everything from the China-based Laboy glass because I found several threads on this forum
complimenting the quality of their glassware.
I placed my order 2 months ago and received the confirmation of payment soon after the transaction. I also received the order confirmation from the
company a day later or so. Unfortunately, I have not received the order or heard from them ever since. I tried to contact them a few times by email
but their customer service is not responding. I'm still hopeful that I would receive the order one day, but after two months, it starts to seem
hopeless. Therefore, I cannot recommend to order from this company although their prices are pretty competitive.

Just to give a short update on my previous post, my order finally arrived after ~3 months from ordering. I finally received the tracking number after
2.5 months from ordering and after that the order arrived within a week. The glassware was properly packed and in good condition. I must say that I'm
pretty happy with the double vacuum manifold that normally costs around 1000$. From Laboy, I was able to get it for a quarter of the price. Also other
glassware ordered (Schlenk tubes, some round bottom flasks etc) seems pretty decent quality and I have no complaints so far. Only problem with this
company is that their customer service is pretty much non-existing. I sent them several emails asking about my order and never heard anything back
from them. I guess it would be much safer option to order Laboy glassware through eBay or other company because then you are protected by their
customer service in the case something goes wrong.

Three weeks is reasonable, three months is not.
I Like Deschem. In Portland, Oregon..... Stuff arrives within three weeks.
Excepting, of course, those times when items arrive after only 5 to 7 days.
Close to China.
