Gull Laboratories Inc., a Salt Lake-based medical products manufacturer, announced a merger Tuesday with Cincinnati-based Meridian Diagnostics for $3 a share.

Gull's majority shareholder Fresenius AG, of Bad Homburg, Germany, has agreed, subject to certain conditions, to vote its shares in favor of the merger.Earlier this month, Gull Labs announced it expected a substantial lost in second quarter revenues attributed to decreased product prices in Europe and a $500,000 severance payment in connection with the resignations of two executive officers.

Gull Laboratories Inc. manufactures diagnostic test kits for the detection of infectious diseases and autoimmune disorders. Gull also offers a line of instrumentation for laboratory automation and products for blood grouping and HLA tissue typing for transplantation.
