Greetings from Oz
I had similar issues with an unstable step, so purchased this ladder which is also used at the University of Sydney NMR Facility:
http://www.ladders4u.com.au/product/platform/pro-series-aluminium-platform-ladder-5-2-(2ft-0-6m-platform-)/114
There were a number of ferromagnetic components that I had our mechanical workshop strip out and replace since it was to be used next to an unshielded Oxford 400 MHz magnet. Doubled the cost of the ladder but gave me peace of mind! One thing though is to think about the platform height - it's great for putting samples in/getting them out, but one of our staff found it a bit low for doing helium fills (he struggled to get the transfer line out at the end of the fill).
Kind regards

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.
