Frequently Asked Questions
Q: I conduct biological research. Can I autoclave the PDMS micro stamps?
Q: What is the difference between PDMS and Urethane rubber?
A: PDMS is more resilient to harsh chemicals than Urethane rubber is. Many liquids wet Urethane rubber better than they wet PDMS.
Q: Some handling is required for my work. Are the micro structures on the stamps durable? Are the micro stamps flexible?
A: Yes. The polymer micro structures are a durable rubber that withstands physical handling and pressing. They bend but do not break. The stamp itself is flexible and can be bent into curved shapes.
Q: How do the micro stamps arrive to me?
A: They arrive in protective transparent plastic packaging. The pristine micro structures face up, and the smooth back of the stamps are down, pressed against the packaging. There are no adhesives. Van der Waals forces hold the smooth stamp back to the smooth plastic packaging.
Q: Can I send RMS a mold to produce stamps?
A: Yes. Send us a message explaining the mold material(s), size, and shape. We will determine the best way to use your mold.
Q: I know microcontact printing is a powerful technology, but I want a collaborator to conduct the work - not just a supplier. Does RMS collaborate on large R&D projects?
A: Yes. We have collaborated with industry, universities, and national laboratories to create new patterns, devices, and processes. Send us a message describing your needs.
