Science

I have purchased all of the equipment from university surplus sales by procurement. liquidation.  My project hasn't fully come into fruition, but it has allowed me to proactively amass capital to begin with.  Only two cons, the time researching, bidding for auctions, and delivery/pick-up.  I still have a biosafety hood covered outdoors as I have to get help moving it, and finding a semi-permanent home for it.  It's so heavy. So decisions with the freight shipment process is a learning curve, or securing help at a pick-up. But the pros are worth it, I recent drove 10 hours round trip for an entire truck full of new, old lab supplies. I highly approve of your plan. If nothing else just to ended the life of perfectly fine equipment, and lighten the load of landfills.

Electronics engineers like 20-40 year old test equipment from name brands
because it usually still works, and often is repairable
more than the current machines. Plenty of mentions of things for sale are allowed and someone made a separate groups.io group
just for selling, with moderation and the same types of listing details as mentioned above:
Item name,
Point of origin
Condition
Willing to ship or not
Dimensions, weight
photos, videos

But they stop short of time consuming anything being required
not Video call demonstration.
not verifying

Those steps are buyer beware. That said, there is a community cohesion and people who have
given bad treatment to buyers in the past have been run out of the group.

So, there is precedent of such listings working well and being valuable, helpful.

Hey Yurij,

I agree with you. Would like to have that option.

If you know how to organize it, would like to help.

Sincerely,
Marko Komlosh

What do you think if this group had a for sale or free section/thread of lab equipment? I ran across some charitable fundraising recently looking for one or two lab tools. Before I knew it, I had an inbox with 10 inventories that had to find a new place before owners rent runs out. These organizations are willing to ship, of course. Some tools are too heavy to be shipped. Others are niche items.

Universities are always shedding some lab tools. Barter systems could work between labs not wanting the clutter.

I am not suggesting the entire deal be in the open thread on this forum, just that its available and declared when it isn't once the deal is agreed upon once done.

I doubt landlords or real estate agents would find their way here but it could also extend to facilities wanting to invite Bio Labs. I know of at least one community lab looking for a new place around NYC's Long Island City.

Thoughts?

I'm in need of a refrigerated centrifuge for my agrobacterium electroporation experiments, but they're difficult and expensive to come by - even used on eBay. They're also super heavy and so shipping is also cost prohibitive. 

I'm considering buying a small mini-fridge and just running a small microcentrifuge inside of it after cooling it down overnight.

I don't think it'll be as efficient as most refrigerated centrifuges have coils tightly wrapped around the centrifuge chamber, but it'll def. be better than nothing.

Has anyone tried this or any other alternatives? 

Best,

Josh

Thanks Srivatsa - that's a great idea.

Hey Josh,

   I do not know the volumes that would be used for centrifugation. 1.5 mL tubes could be centrifuged by placing them inside 50 ml tubes (bigger tubes) along with crushed ice as long as the duration is not very long. The 1.5Ml tubes could also be parafilm sealed.

  Not an ideal solution but could work.

Otherwise, I would buy a mini centrifuge and use it in a fridge as you described.

Thanks,

Sri

Do you have access to a coldroom?
