NanoFab Tool: PDMS Casting Station


The CNST NanoFab PDMS casting station consists of a Hamilton Safeaire fume hood which houses a Smart Coater 100 spinner, a Dataplate digital hot plate, an Ohaus Scout Pro digital scale, and two Bel-Art desiccators. The casting station provides users with all of the tools necessary to mix, de-gas, cast and bake elastomeric polymers, primarily polydimethylsiloxane (PDMS) to replicate master molds using spin-cast and drop-cast techniques. All tools in the casting station can accommodate substrates ranging from 150 mm wafers down to small pieces.

  • Maximum spin speed: 10,000 rpm.
  • Maximum acceleration: 10,000 rpm per second.
  • Time resolution: 0.1 second.
  • 100 spin programs can be defined and saved for future use.

Dataplate 731 Hotplate:

  • Temperature Range: room temperature to 370 °C.
