Taylor Molybdenum Drop Test Kit, Complexometric (Powder), 1 Drop = 2, 5, 20, or 50 ppm

Taylor Molybdenum Drop Test Kit, Complexometric (Powder), 1 Drop = 2, 5, 20, or 50 ppm

The Taylor® K‑1805P Molybdenum Drop Test Kit is a complexometric titration kit designed for accurate field measurement of molybdenum in industrial water systems. Using a powdered indicator for enhanced stability and sharp color transitions, this kit supports multiple test ranges—2, 5, 20, or 50 ppm per drop—making it suitable for a wide variety of treatment programs. It is ideal for monitoring molybdenum‑based corrosion inhibitors in boiler, cooling, and closed‑loop systems.

Key Features

• Analyte: Molybdenum (Mo)
• Chemistry: Complexometric titration using a powdered indicator for increased stability
• Multiple test ranges: 1 drop = 2, 5, 20, or 50 ppm Mo (procedure‑selectable)
• Clear visual endpoint: Sample shifts from reddish‑orange to match a peach‑colored blank
• Field‑ready kit: Durable case with fitted components for route and plant service work
• Industrial applications: Supports corrosion inhibitor control and treatment verification

Typical Applications

• Boiler and cooling water: Monitoring molybdenum‑based corrosion inhibitors
• Closed‑loop systems: Verifying inhibitor dosage and system protection
• Industrial process water: Routine molybdenum checks in treated water circuits
• Field service and route testing: On‑site analysis for water treatment programs

Kit Components

• Calibrated pipet, 0.5 & 1.0 mL (1)
• Calibrated pipets with caps, 0.5 & 1.0 mL (2)
• 3 mL syringe (1)
• Sample tubes, 25 mL graduated with caps (3)
• R‑0890 Molybdenum Buffer Solution, 2 oz
• R‑0892 Molybdenum Titrating Solution, 2 oz
• R‑0900 Molybdenum Indicator Powder, 10 g
• R‑0901 Molybdenum Indicator Solvent, 2 oz
• Instruction sheet (Procedure #5359)

Test Method Overview

• Indicator preparation: Powder + solvent mixture produces a stable reddish‑orange indicator
• Blank vs. sample comparison: Blank turns peach; sample remains reddish‑orange until titrated
• Titration: Add R‑0892 dropwise until sample matches blank
• Calculation: Drops × selected factor (2, 5, 20, or 50 ppm)

Conversion Factors

• Mo → Molybdate (MoO₄): multiply by 1.7
• Mo → Sodium molybdate dihydrate (Na₂MoO₄·2H₂O): multiply by 2.52

The K‑1805P is a rugged, service‑grade molybdenum test kit engineered for reliable field measurements and industrial water treatment control across a wide concentration range.
