Objectives

The primary objective of this tender is to procure reliable, high-quality chemical reagents for municipal water quality testing. The municipality seeks to maintain uninterrupted laboratory operations for manganese and iron analysis by securing a qualified supplier capable of delivering standardized analytical kits at competitive rates, while complying with national preferential procurement policies.

Scope

The scope encompasses the supply and delivery of three categories of laboratory reagent kits, bundled into a single procurement lot. Tenderers must provide a consolidated lot price covering all specified quantities. Deliveries must align with the municipality's standard supply chain protocols, and successful bidders must be registered on the municipal supplier database. All quotations must remain valid for a minimum of thirty days from the submission date.

Technical Requirements

• Manganese Reagent Set LR (Low Range): Five (5) kits, each containing 10ml volumes in packs of 50. Each kit must include alkaline cyanide reagent (50ml) and ascorbic acid powder.
• Manganese Reagent Set HR (High Range): Five (5) kits, each containing 10ml volumes in packs of 100. Each kit must include citrate-type buffer (pack of 100) and sodium periodate solution (10ml, pack of 100).
• Ferrover Iron Reagent: Five (5) packs of 100, including pan-indicating solution (50ml, 0.1% concentration).
• All reagents must meet analytical-grade specifications suitable for spectrophotometric water testing.
• Pricing must be submitted as a single lot total; individual item pricing will not be evaluated separately.
• Submission must be completed electronically via the designated online portal. Fax submissions are explicitly prohibited.

Skills Requirements

While no formal academic or professional certifications are mandated, suppliers are expected to possess demonstrated experience in chemical logistics and laboratory supply chains. Key competencies include safe handling and transportation of sensitive analytical chemicals, adherence to hazardous material storage and delivery standards, and familiarity with municipal procurement compliance. Suppliers must also maintain robust inventory management and reliable last-mile delivery capabilities to prevent laboratory downtime.

Explanation of Specialized Terms

• 80/20 System: Refers to South Africa's Preferential Procurement Policy Framework Act (2022), which allocates scoring out of 100 points: 80 points for price competitiveness and 20 points for socio-economic transformation targets (e.g., black economic empowerment, local business participation).
• Ferrover Reagent: A proprietary colorimetric test kit used to quantify dissolved iron concentrations in water samples through spectrophotometry.
• LR/HR Reagent Sets: Low-Range and High-Range analytical kits calibrated for detecting different concentration thresholds of manganese, ensuring accurate measurements across varying water treatment stages.
• Pan Ind Solin: Abbreviation for pan-indicating solution, a chemical indicator that changes color upon reaction with iron, enabling visual or instrumental quantification.
