Labflow overview - Catalyst’s Labflow product is a cloud-based web app that delivers purpose-built courseware for chemistry and biology lab courses. Labflow delivers safety and instructional videos, digital lab reports and quizzes. It also provides targeted section management and data insights for instructors and TAs. 

Labflow has been built mobile-first so it works on laptops, tablets and mobile devices (without the need for a separate native app)

Integration overview - Labflow’s supported LMS integration approach is accomplished by adding Labflow as an LTI Tool Provider (LTI spec 1.3) and exposing it as an external tool link in the respective D2L courses. This provides SSO and grade synchronization back to your LMS. Labflow is a 1EdTech certified LTI Advantage member.

The integration is accomplished by exposing the Labflow link as an external learning tool inside of a D2L course. This integration is LTI 1.3 and facilitates: SSO, course and activity linking (not 'deep'), and grade return.
