Immunoassay Substrate and Components

亚博最新客户端 is committed to serving medical diagonostic and biotechnology firms worldwide. We supply precision-made, custom-produced beads for use in diagnostic, research and development, protein purification applications with associated components manufactured in a Class 8 Clean Room.


Exacting Quality and Visual Inspection Systems:
To assure uniform coating of beads and repeatability of test, we use automated visual inspection systems.  This ensures repeatable quality standards for identical shape and surface finish.

We recognize the critical importance of lot traceability and product verification for the medical diagnostic and biotechnology industries. Therefore, complete documentation and certification for all materials and manufacturing lots is assured.

Custom Manufactured to Your Specifications:
Product is tailored to your specifications, with sizes as small as 2.0mm and with medical-grade surface finishes from 10-280 Ra (other surface finishes also available). Beads are molded from polystyrene, with other materials available per your specifications. Small quantity product samples are available to assist you in selecting the solid phase bead with the ideal physical adsorption properties for your application.

We are committed to a continuing research and development program, pursuing further refinements in surface finishes and developing additional materials for diagnostic applications.

Flexible Lot Size Capabilities:
With our flexible production capabilities, we can supply the quantity of beads that meets your requirements. 25,000 - 1,500,000 piece batches.

Pre-shipment Samples Available:
To verify that beads conform to your specified parameters, pre-shipment sampling for approval is available in the quantities that you request.

Precise, Durable Packaging:
Every shipment, including preshipment samples, contains complete and accurate labeling and full documentation. Packaging construction is sturdy, damage-resistant and guaranteed to preserve the integrity of these precision-manufactured beads.

Efficient Shipping Services:
From the manufacturing facility in Michigan, we provide efficient, timely shipping services, utilizing expeditious air-freight routes for all overseas shipping.  Customers with JIT inventory systems will appreciate our inventory capacity, which allows us to ship in multiple releases on committed manufactured orders.
