DENSO contributes to automation in medical device / medical product manufacturing and drug preparation.

DENSO delivers a robot that meets the strict demands of the pharmaceutical and medical industry. Automation in clean environments prevents the hazards of foreign matter contamination from manual tasks, human error, and operator exposure.

Technical Feature

Sterile environment resistance/Resists Contamination

Robot for use in sterile environments and clean environments that employ H2O2 gas 35% density (dry / wet) and UV exposure.
Smooth surface prevents adherence of dust and dirt. The robot arm is constructed without external screws to maintain high sanitation levels.
Cleanliness : ISO Class 5 Protection level : Wrist IP67 / Unit IP65

Isolation (suitability for sealed environments)

Cables and other connector panels are positioned on the bottom for compatible installation in sealed and quarantine environments


●Design compliant with GMP* (product management and quality control standard). *GMP grade A
●cUL certified products (UL standard / Canada CSA standard) also available.
●Hygiene proven through testing by the Fraunhofer Institute (Report No. DE 1409-725).

Examples of Applications

Automation of cell culture

●The movements of skilled workers are reproduced by robots to realize the automation of high-quality cell culture without variation in quality caused by operators.
●The hazards of foreign matter from manual tasks, human error, and operator exposure are avoided, and a clean and safe system is realized.
●Robots can reproduce the same function as the manual operation by operator, such as opening the pipetting cap, using general-purpose tools.


Electric gripper connection flange specification-A

Internal mount with a gripper cable up to the flange. Suitable for clean environments, eliminates interference with peripherals.
