Applications
- Stirring viscous solutions in unique vessel geometry where the stir element can be designed to fit the unique geometry and maximize stirring efficiency.
- Provide maximum magnetic coupling with the drive magnet to effect high RPM stirring.
Solvent Testing
The High Temp 3D resin has been Solvent tested by the source of the resin and by V&P Scientific, Inc. and holds up very well against most common solvents except Chloroform and strong acids. See the tables below and the testing protocols.

Experimental Protocol
- Prepare high-temperature resin cubes of dimensions 10mm x 10mm x 10mm
- Take measurements and the weight of the cube, first measure
- Using a 20mL glass vial, submerge the cube in 10mL of the desired chemical, tighten screw lid
- Wait 24 hours
- Dump chemical waste into a dedicated waste container
- Remove the resin cube and pat dry with a paper towel
- Take measurements and weight of the cube, second measure
