EUROPLEX® COC FILMS FOR MICROFLUIDIC APPLICATIONS

Technical Information

Product Characteristics

High transmission

EUROPLEX® COC Films for microfluidic applications provide excellent light transmission and brilliance due to a low intrinsic absorption.

Chemical resistance

EUROPLEX® COC Films exhibit outstanding chemical resistance for a variety of solvents, e.g. acetone, ethanol, isopropanol, ethyl acetate, as well as very good acid and base resistance.

Thermal stability

Two types of EUROPLEX® COC Films are available with glass transition temperatures of 78°C and 142°C, respectively. This helps customers to realize applications with various requirements in thermal stability.

Biocompatibility

With regard to the composition, the applied COC polymer material complies with the regulations of the European Pharmacopoeia, Monograph 3.1.3. “Polyolefines”.*

Processability

EUROPLEX® COC Films can be easily processed by laser cutting and laser welding.

Bonding-process

The following bonding-processes are suitable:

  • Laser welding
  • Thermal bonding
  • Solvent bonding, e.g. using cyclohexane or toluene
  • Ultra sonic welding

Service

Clean-room conditions

An important point for microfluidic devices: Röhm produces under clean-room conditions.

Masking-films on both sides

Masking-films can be applied per customer’s needs.

In-house cutting

The customer asks and Röhm delivers. In-house cutting by Röhm allows customers to have their individual requirements met. The customer receives an all-in-one quality product and service by Röhm.
