I've noticed that Bruker changed the sample depth gauge from a cylindrical acrylic (identical diameter as a spinner) with metal leadscrew depth stop, to a cast acrylic square fixed gauge, to a adjustable cylindrical acrylic gauge with hexagonal bottom fitting. I suspect the changes over the years have been to make it impossible to drop a depth gauge down the bore of a magnet.
If you're lucky, there's no metal inside the depth gauge then a stiffer piece of 1/4" PP tubing or 3/8" tubing should be enough to push it out without scratching the upper half of the BST. You can get this from the Home Despot or your local hardware store, typically used for plumbing ice makers, water coolers, humidifiers, etc.
If you're unlucky and it's a gauge with ferromagnetic adjustment screw, then you might have to resort to carefully removing the entire upper BST (if you know how) with gauge inside just to get it out (might as well clean the spinner jets while you're there!).

Subject: AMMRL: Gauge in magnet
A user put the gauge and sample into my DRX 400. The sample came up but the gauge didn't. After I removed the probe I tried pushing up from the bottom with stiff plastic air line but I think the natural bend in the air line is causing it to get lodged on the shelf and not get to the center where the gauge is. Pushing up with Tygon has the same bend problem.
Thank you in advance.
