About Us

We are a manufacturer of high-quality diagnostic stains and laboratory reagents. Founded in 1999 and acquired by Polysciences in 2015, we have spent 20 years committed to excellence in the chemicals industry. Our top priority is to ensure that our customers’ needs are met with timeliness and care in a cost-conscious manner. We continue to proudly serve suppliers, the medical market, and academic community with a commitment to provide superior service and quality products.

Our Commitment to Service
Astral is uniquely positioned to offer highest-level technical support and troubleshooting assistance. As a manufacturer, we have a deep understanding of dye and stain formulations; this also enables us to achieve highest quality standards for our products. Astral products are supported by fully-equipped, on-site laboratories that are staffed with experienced technicians. We understand the laboratory ecosystem, and are able to provide truly authentic support to our customers. We’re happy to assist with product selection or protocol review, and will take our troubleshooting to the bench if a deeper investigation is required.

Our Commitment to Quality
At Astral, quality extends far beyond basic dye formulation and concentration checks. Our fully-integrated program ensures control from start to finish—it begins with raw materials, and encompasses dye and reagent formulation, manufacturing and quality control. Product QC is comprehensive, with performance testing that features actual specimens to ensure that dyes meet expected intensity and cellular component differentiation criteria. For Astral, Quality isn’t simply a claim—it’s the cornerstone of our philosophy and our commitment to you.

At the end of the day, we do all of these things for one purpose: to serve our valued customers.
