Abstract
This invention generally relates to a device for preparing and transferring a monolayer or thin film. In particular this present invention is a device for preparing and transferring a monolayer or thin film to a substrate using an improved version of the Langmuir-Schaefer technique, which incorporates in situ thermal control, for instance to heat the supporting substrate before and/or during the transfer process.

A device for transferring a monolayer or a thin film comprising
- a) a magnetic sample disc;
- and
- b) a heater body encompassing
- i. a cartridge heater operatively connected to a temperature controller for heating and temperature control;
- and
- ii. a thermocouple operatively connected to the temperature controller for heating and temperature control;
- and
- c) a magnet positioned at one end of the heater body to provide sufficient force for picking up said magnetic sample disc without physically touching the magnetic sample disc.
