Discover how BIOSTELLAR optical dissolved oxygen measurement works and how it differs from the conventional polarographic method. With no oxygen consumption during measurement and no electrolyte replenishment, optical DO technology is a practical option for low-flow water, small-volume samples, aquaculture and environmental monitoring.

The BIOSTELLAR D-500 High Shear Homogenizer is ideal for laboratory homogenization, solid-liquid dispersion, and emulsification in pharmaceutical, biotechnology, cosmetics, food, and chemical applications. With interchangeable dispersion heads, it accommodates different sample types and volumes. This guide helps you choose the right configuration for your needs.

Discover how the BIOSTELLAR EC10 conductivity meter, paired with the DDJS-0.01VTK low-conductivity electrode, supports routine testing of pure and ultrapure water. Featuring a 3.5-inch TFT color display, storage for up to 3,000 data sets, flexible calibration functions and IP57 protection, EC10 is designed for laboratory workflows in pharmaceutical, semiconductor, water treatment and research applications.

BIOSTELLAR provides integrated pharmaceutical QC laboratory solutions designed for tablet quality evaluation, injectable drug analysis, and contamination control. The solution covers essential testing processes including tablet hardness, friability, disintegration, osmotic concentration analysis, and liquid particle inspection, helping pharmaceutical manufacturers build efficient and reliable quality control workflows.
