HI-781-25 Hanna Low Range Nitrate No3 Reagents

Product details

HI-781-25 Hanna Low Range Nitrate No3 Reagents are replacement, pre-measured chemical reagents made for use with the Hanna Instruments HI-781 Marine Nitrate Low Range Colorimeter. These reagents support accurate nitrate testing by using a colorimetric reaction: when nitrate in a seawater sample reacts with the reagent, the sample develops a pink/violet tint that can be read with the colorimeter. If you’re running low on test chemicals or replacing a previously opened kit, this refill helps you keep your nitrate measurements consistent and repeatable for aquarium and marine water monitoring.

Features:

• Pre-measured reagent packets help streamline nitrate testing with the HI-781 colorimeter
• Uses a colorimetric method where nitrate drives a pink/violet color change in the sample
• Designed for seawater nitrate colorimetric testing with the HI-781 system
• Each packet is clearly marked with lot number and expiration date for traceability
• Reagents are prepared with high-purity chemicals
• Includes paper filters to support sample clarification as part of the test workflow
