Lab Stands + Questions


How is this for a lab stand?

https://www.ebay.com/itm/Lab-Laboratory-Retort-Stands-Suppor...

It seems pretty inexpensive, I get tired of buying them...

Would this work to hold up a distillation apparatus?

I see online how certain distillation apparatus's are held up with only 1 stand, but 2 clamps -- would this work? If not, what else would I need to setup a distillation apparatus?


I'm really wanting to save money


Also, what diameter ring goes with what separatory funnel?


Hmm...

15*8.5cm base and 30cm height, in my opinion it would be ok for microscale distillation, surely not for a 24/40 set and 500ml flasks.
how is $13 cheap?
buy 3 feet (1m) of 1cm (1/2") steel rod or tube, as a base you can use a wide wooden base, or a smaller steel/iron/concrete/lead base.
with 13 dollars you should be able to build at least 5 of those stands...

i built mines with a 1cm diameter steel rod 60cm high, and one has a wooden base, like 20cm*30cm and the other has a marble base 15*20 (found discarded cuts a build site)

I have always noted retort stands online are unreasonably expensive. It is true that you can easily make something yourself at a fraction of the cost.
I built a rack made from nickel-plated drawer handles.
If I didn't have that, then I would be off to the industrial end of town with a sketch on a piece of paper and a sixpack in hand and asking someone what they could knock up using scrap from the bin, a couple of tacks of a welding stick and a few minutes of their lunch break.

I literally just got one of these but it's so much smaller than I thought it would be and one of the clamps wouldn't lock tightly and slid up and down the steel pole and no matter how tight I turn it it just won't lock to it.also the steel loop isn't big enough even for a 250ml SEP funnel to sit in. Spend a few dollars more and get a bigger one with bigger clamps.

No it's not big enough to hold up a distillation setup unless you're talking microdistillation with 50ml flasks.

Literally done that and got 4x 60cm high stands made up for $20. Only thing is i found out that mild steel rod bends when trying to support a 3 ltd half full flask.so if doing this the rods need to be ss.the base plates can be mild steel though.

what's the diameter of your rods? mine are 1cm in diameter and made of mild steel, i could bend them maybe with my weight, surely not with a half full 3L flask

I saw Dr.Bob posted in a thread like this saying he uses the 2x8 (iirc) and drills a 7/16 hole for a 1/2 rod and presses it in somehow. I'm wondering if it'd be best to have the hole go all the ways through the block? I'll probably do the same thing.

Walmart has 3/8 wooden dowels and other goodies in the arts and crafts diy section

Would a wooden dowels work for a rod or do I need it to be metal? I could glue the would into the hole but it might snap when I press it in. Also, I'm not sure how I'm going to press it into the hole?

They look pretty cheap and nasty to my eyes - probably well worth springing up to around 2x the price to get something better, or get some threaded metal rods and make some nice solid heavy bases to drill the mounting holes into. Then couple your DIY stands with some quality mounts and rings etc.


I particularly like the idea of using marble offcuts for the bases - nice and heavy, looks good and will take spills etc. like a champ. :cool:

I'm not sure how the rod would connect to the marble, I have very limited construction skills. -- would I want to take a carpentry class to learn about screws, tabs, and DIY or some sort of construction gig?

Yeah 1cm. They were not the threaded stuff you get from the hardware store.just normal smooth 1cm 60-90cm tall mild steel rod.they just have too much flex in them
whereas ss won't flex at all.if you keep the flask size under a litre I suppose it wouldn't bend too much if kept low as long as your not distilling mercury.

That would be overkill.just watch a few you tube videos on the subject.
But the idea of using marble is a nice idea.

i only have a hand drill, so i drilled a 9mm hole ( a drill press does the job fast and easy) in the marble slab, drilling by hand the hole got a bit wider than 9mm but still less than a cm in a few places. a light touch with a file and the rod is press fitted in the hole. i drilled an oblique hole though... so my stand has a 10° inclination to one side

I'll probably go with one of these, I wasn't sure what they were called

Also am posting this in case no one else knows of these flange things

Now, is there any additional special hardware one needs to mount these besides some screws and the poles?

Is there a screw recommendation ?

I may go with what Dr.Bob said in another thread, to press the 1cm rod into a 7/16 hole-- this may be the cheaper route, actually I'll probably do this.


Any suggestions for what rod is the cheapest/ where can I acquire one? Links?

And how do I still a hole that is centered???

Placing a RB flask on one of those metal rings and then heating it with a bunsen flame is a great way to break glassware.

in a modern country every hardware store has steel rods, they are not expensive at all.

to drill a straight hole you need a drill press, or a very firm hand, two things i don't have

I know that they're different things, but I can't help thinking that anyone who's of a mind to (attempt to) perform semi-serious home chemistry shouldn't have much of a problem figuring enough simple DIY to make a ghetto but functional lab stand out of bits of scrap.

In suppose let's just thank god we're not in the Before Times of Amateur (& Professional) Natural Science where you had to be half decent at making and hacking your own glassware if you wanted to actually do anything. :cool:

Doesn’t look like something I would ever trust with my glass. Spend a couple extra dollars to buy a decent stands.
This is a solid one that I use for everything.

I think It's a thing that is used on boats or display stands.i know a boating supply would have them in 316ss and I've seen some in hardware stores too.wherever chrome plated mild steel tube is available.ahhhhhh wait a sec curtain rods.there curtain rod mounts.no wait there for the rods you hang your clothes on in the cupboard.i use a floordrobe despite having an empty wardrobe so i forget what you call them .on boats there used for mounting the ss
railings around the boat.

18 bucks isn't a bad price to pay to protect your precious glassware, reagents and health from some avoidable mishaps if you can't be bothered to DIY one IMO. Especially if it's easy to add extra weight to the base with them.
