New document outlines how groov products are being used in 21 CFR Part 11 approved applications.

If you work in pharmaceutical or biotech manufacturing, you’ve probably had to think about 21 CFR Part 11, the FDA regulation that governs electronic records and electronic signatures.

That’s where Opto 22’s groov platforms come in.

New Who's groovin' video series lets you preview a variety of industrial application challenges and solutions.
