Since 1984, Solomon Park has been supplying laboratories across the globe with the highest quality frozen serum and frozen plasma products. Serum and plasma is shipped fresh or frozen and is obtained from donors with known analyte values.
Our draw center, located in Burien, Washington, utilizes a process (C37-A) developed in conjunction with the CDC. The resulting serum and plasma products are highly accurate and almost indistinguishable from a human test sample, as such our products are often used to establish quality controls and to develop standards and proficiency testing materials by outside laboratories.

They are also used by equipment manufacturers to create white-label calibrators and controls.

Solomon Park also provides ultra-low temperature storage space for longitudinal studies. All freezers and facilities are protected by a redundant power source.
