SSA - Mettler Toledo Rainin pipette tips

The Idaho Department of Administration, Division of Purchasing, is approving a sole-source authorization for the Idaho State Police to purchase Mettler Toledo Rainin pipette tips from Mettler Toledo - Rainin, with a challenge period closing September 27, 2026 (five business days after the September 22 notice-closing date under Idaho Code section 67-9232(4)).

This is a sole-source procurement. The Idaho State Police Forensic Services DNA Unit requires Rainin-branded pipette tips for use with Rainin pipettors in validated DNA laboratory testing and analysis. The ISP justifies sole-source procurement on the grounds that Mettler Toledo Rainin is the sole manufacturer and distributor of tips compatible with the laboratory's validated testing processes. The agency researched alternative suppliers, including Fisher Scientific and VWR, which offer Rainin-compatible products; however, ISP determined that these alternatives have not been validated for the laboratory's specific DNA testing procedures and that substituting unvalidated tips could compromise testing accuracy and reliability. Revalidation would require significant laboratory resources and costs. Mettler Toledo Rainin's supporting letter confirms that the company can only guarantee the accuracy and performance of Rainin instruments when used with Rainin original-equipment-manufacturer consumables, and that Rainin is the sole authorized provider of repairs, preventive maintenance, and calibration services for Rainin instruments in the United States.

The anticipated total cost is $50,000 over a three-year contract term with no specified renewal options. Interested vendors may challenge this sole-source determination by submitting timely notice to purchasing@adm.idaho.gov within five business days after the closing date.
