Inhibition Zone Reader

Science Emporium > Life Science > Inhibition Zone Reader

Inhibition Zone Reader

Detection on all Petri dishes

Scan Automatically detects the peni-cylinders, present or removed, made of steel or plastic. It also reads agar wells or paper disks (any brand). Add/remove disks manually. The inhibition zones can also be resized. Scan 1200 allows reading on blood, chocolate or Mueller Hinton agar.



Scan®is an inhibition zone reader for antimicrobial susceptibility testing. It enables checking the susceptibility of bacteria to antibiotics and offers quick, traceable and complete results to validate a medical choice.

In compliance with CFR 21 part 11, EUCAST, CA-SFM, ISO 7218, ISO 4887-2

Automatic separation of confluent colonies

Automatic elimination of counting grids

21 CFR Part 11 included

The Scan software responds to FDA recommendations, including electronic signatures, audit trails, and security of results. User account management is integrated into the software. The supervisor can manage accounts and passwords directly, without always calling on the network administrator.
