The Blank Base Chip can be used in combination with the Resealable Chip Interface (Part No. 3000305) and a Top Chip (Part Nos. 3200069-72). The chip is made from glass and requires a Top Chip to create a fluidic seal. There are no etched features on this chip. Examples of use include the deposition of thin layers onto the surface of the chip prior to assembly in the holder for fluidic experiments.
