In most cases, a 2000g, 6000 rpm minifuge is all you need for mini preps and pelleting DNA. Galaxy VWR minifuge for this is $422, brand new, from VWR. This kit is $260. You can pick up minifuges at used resellers for &lt;$50. A basic Dremel tool is about $50. A replacement rotor for the galaxy microfuge (hint, hint) is $70.<div>
<br></div><div>To Patrik&#39;s point: how much is your eyesight worth? Be careful out there. When making plastic covers, use highly resistant materials, like polycarbonate laminates (e.g. MAKROLON). Metal rotors are probably a better idea than plastic ones. IMO, the brand new minifuge is not so expensive and has clearly traceable product liability. DIY in this case might be a great learning tool, if by &quot;losing an eye&quot; you learn what not to do.</div>

<div dir="ltr"><div><div>I would also want to see what happens to that thin acrylic cover when a fully laden tube ejects from the rotor at full speed. High speed centrifuges are explosion-prone devices, and need to be tested as such. Flying shards of acrylic are no fun...<br>

<br></div>The typical recommendation for using the dremelfuge are to hold it inside a metal cooking pot - at least that will give you some serious protection.<br><br></div>Patrik<br></div><div class="gmail_extra"><br><br>

<div>Thanks Jenny! Typically for DNA work centrifuge speeds need to be approx. 13000rpm/18000xg</div>
