Hi all,
I've been searching and posting all over the web about this issue. I apologize for the long question in advance.
I had a 304 tray welded at a welding shop specializing in stainless and laser-cutting. The part is a box about 2' x 1' x 1' with 1.2 mm-thick steel walls (~0.05") and a...
Hi all --
There was a thread on gluing cellophane (i.e. regenerated cellulose) to plastics here about 10 years ago. I've been trying to find adhesives for cellophane, but have failed so far. I am trying to make a small floatation device for dialysis which requires a leak-proof seal between an...
Hi all,
Has anyone have across 2-part epoxy which would not swell/fail upon long-term (ovenright) exposure of acetone? Chlorofrom-resistance would be even better, but I doubt it. We assemble water-resistant cuvettes out of glass pieces using 5-min and a UV-curable NOA-61 epoxy, which allows us...
Hi all,
I am looking for HSS-machinnable, solvent-resistant, transparent (>50% in 400-900 nm) material to make a top plate for microscopy, about 2 x 2 x 0.25 inches. Is there a transparent analogue of PTFE or MACOR? Scratch-resistance is less important, b.c. I can cut a window in the middle...
Hi all,
I run a biochem lab; we do fluorescence microscopy in home-made fluidic flow-cells which we make by sandwiching together two borosilicate coverglasses, separated with a 0.5 mm spacer. The spacer (the gasket) is a small (24x40 mm) rectangle of 3M double-sided 4905 VHB tape, 0.5 mm...
