Objectives

The primary objective of this tender is to procure a Gel Documentation System suitable for PCR applications. The system aims to enable visualization, capture, and analysis of DNA/RNA fragments post-gel electrophoresis, as well as verifying PCR reaction success by confirming amplified DNA bands. Additionally, the system should support documentation and analysis to facilitate laboratory workflows and ensure compliance with technical standards.

Scope

The scope encompasses the supply, delivery, installation, testing, calibration, and commissioning of the Gel Documentation System for PCR at the designated laboratory facilities within the KwaZulu-Natal Department of Health. It includes providing necessary accessories, manuals, training, and support services for the system's operational readiness and ongoing maintenance. The tender also covers optional accessories, future upgrade policies, and compliance with relevant safety and technical standards.
