Re: [DIYbio] DIY Refrigerated Centrifuge

Ive had complete success with Peltier fixtures. this $5 semi moves 8 W and has a 8 by 15 mm face...

KW: Thermoelectric Cooler Peltier TES1-03102 TES1-03103 03104 mini 15*15mm low power 3V2A high efficiency Peltier on ali baba but that search will find it in the product pipeline better for your situation, probably.

If its an ONGOING requirement a fixture with a 9 V battery 555 timer and this would make it stand alone entirely from other open issues for temp.

Until the batteries dead, that is ... Low duty cycle is required so the thing lasts awhile... its all about delta T and thermal resistance, little dissappation material aka 'fin'.

Example idea...

Would you be able to get a sacrificial refrigerator and move your centrifuge into it?

I throw mine inside the refrigerator the night before and run it inside.

Greetings fellow researchers! 

I am in need of a refrigerated centrifuge to process some proteins samples extracted from a mammalian cell line. The lab that I currently work does not have a refrigerated centrifuge to accommodate this. Is there any other alternative way to reduce the temperature of the working conditions?

I was thinkin maybe I could suspend a small eppendorf tube inside a bigger tube filled with water and subject it to freezing. However I am not sure how this would affect the centrifugation procedure.

Looking for your valued opinions on this matter!
TIA
