For many in biologics process development and manufacturing, knowing that your work saves lives, improves health, and alleviates suffering fuels a commitment to quality. But there are times when ensuring quality can feel like it conflicts with the need for speed and efficiency.
Not all osmometers can deliver the same accuracy, precision and speed as those from Advanced Instruments
At Advanced Instruments, we believe that quality and productivity go hand-in-hand and have built a family of products and services to help biologics manufacturers and process developers ensure the yield, purity, and consistency of biopharmaceutical products through osmolality testing..
Whether you need to maintain optimal cell growth, ensure active pharmaceutical ingredient (API) purity and yield, or confirm quality during fill and finishing, we offer an advanced osmometer that will keep your processes productive and on track, saving time and reducing costly re-work.

Busy labs often look to automation to ensure timely sample processing, but analyzing CSF samples – especially those at clinically relevant low cell counts – can be time-consuming and challenging. For labs that want to improve results consistency and turnaround time, there’s an Advanced Solution that meets this need with GloCyte.
Our CSF cell counter automates handling of all CSF samples, detecting down to 1 cell/µL and delivering total nucleated cell (TNC) and red blood cell (RBC) results in less than 5-minutes using only 30 µL per test, GloCyte gives labs a reliable and efficient method for automating analysis of all CSF specimens.
