Hi everyone,

Does anyone know where I could purchase some ultralene gridded protective windows (sample temps <150C) for our Tracer III-V+? Bruker is no longer selling them (our instrument is considered obsolete), and we are down to our last one!

Thank you!

Hi Kirsten,

I recently ran into this dilemma with our Tracer III-V+. A colleague recommended using a piece of Dartek and securing it with blue tape. It's a work-around, but it does indeed work!

Thanks,

Colleen

I bought 1 inch wide double sided tape and made an oval cutter using brass tubing (filing down the inside to make it sharp). I use the cutter on the tape and then use any polymeric film - Dartek works, I prefer thinner ones I buy from

Hi!

There are multiple options pending on your setup

Some TRACER III SD or IV have the GRID separate from the window and you can just use a 4 micron PROLNE foil window from the S1 TITAN or make one using PROLENE cut circles from CHEMPLEX and some Scotch tape.

For those with the integrated window you can recycle and remove the grid and attach a new PROLENE 4 micron foil and use tape around it.

If there is no grid left look for the NEW TRACER Vacuum windows for the T5 and adapt them.

I would believe that TRACER IV or III SD windows are also compatible if they have the grid… The latter can be made by yourself out of a sturdy Mylar film.

PROLENE is a trademark from CHEMPLEX in the US and a “clean” 4 micron Polypropylene PP. Check the CHEMPLEX resellers on the website.

Any 4 micron or less CLEAN PP can be used e.g. FLUXANA, SPEX CERTIPREP etc…

There are some with a sticky ring :) called protection windows which are used on the CTX…

Thank you everyone for your responses! This has been extremely helpful! Also thank you to Elliot Blair at University of AL who mailed me some windows from their now-defunct Tracer.
