Dr. Win-Piazza;
We have plastic 4 step stairs available with a 500# capacity available from most industrial suppliers such as Grainger<https://www.grainger.com/product/DPI-Box-Steps-WP6591503/_/N-/Ntt-4+step+ladder+plastic?NLSCM=46&optOut=0&sst=subset&s_pp=false&picUrl=//static.grainger.com/rp/s/is/image/Grainger/38GU03_AS01?$smthumb$> on both our VNMRS 600 and one of our Inova 500s. The picture shows the stairs before we installed a grounding system which dissipates the static charge generated when the person climbs the stairs. It's better to receive a shock on the bottom of the stairs than to get a shock on top of the magnet dropping the sample and breaking it there ... and perhaps falling. They are expensive and you might want to shop around.
Also depending on whether you have a shielded magnet or not we recommend going to Ace Hardware<http://www.acehardware.com/home/index.jsp?prof=52&affcode=130566> and getting some non-magnetic stainless steel bolts and nuts to replace the ferrous hardware.
Enjoy NMR,

Subject: AMMRL: Ladder for NMR
Hello Ammrl,
A few users have fallen off from wooden NMR ladder. So, I am looking for a study ladder with hand rails. Will you please recommend a few vendors and model out there? I am thinking aluminum ladder with working platform. What material would you recommend? I have 500 MHz oxford magnet. Thank you.
