Ambu® aScope™ Gastro Large

A world of difference with 4.2

The world’s first gastroscope with a 4.2 mm working channel gives you the power of a therapeutic gastroscope combined with the manoeuvrability and precision of a standard one.

aScope Gastro Large delivers approximately 90% higher suction flow compared to the newest therapeutic 3.7 mm channel gastroscope.

In addition, because it is a single-use solution, it is always available, sterile and offers consistent performance. So, there is no more waiting when therapeutic gastroscopes are being used, reprocessed, in quarantine, out for repair, or when reprocessing equipment is broken.

What’s more, with the world’s first bioplastic handle, aScope Gastro Large sets new standards for single-use sustainability.
