Accurate water testing is crucial for maintaining safety and efficiency in various industrial applications. CHEMetrics’ Vacu-vials self-filling ampoules offer a superior solution for testing dissolved substances in liquids, combining convenience with reliability. Here’s why Vacu-vials should be your go-to choice for water testing.
Simplified Testing with Instrumental Accuracy
Unlike traditional visual test kits, Vacu-vials allow you to obtain precise instrumental results. Compatible with CHEMetrics Direct-Readout Photometers or any spectrophotometer that accepts a 13mm diameter round cell, Vacu-vials ensure versatile and accurate testing. Simply set the spectrophotometer to absorbance mode, select the specified wavelength from the Vacu-vials kit instructions, and follow the straightforward test procedure.
For instance, the K-1503 Ammonia Kit is designed to measure ammonia levels in water ranging from 0-7.00 ppm with high accuracy, ensuring you get reliable results every time.
Safe and Reliable Results
Vacu-vials test kits stand out for their simplicity and reliability:
- Reduced Operator Error: The streamlined testing method minimizes steps and preparation, reducing the potential for operator mistakes.
- Stable Reagents: Each ampoule is vacuum-sealed, eliminating inaccuracies from stale or unstable reagents. The reagents are securely stored in the tip of each ampoule, minimizing direct chemical contact.
Comprehensive Kit Contents
Each Vacu-vials kit includes everything you need for accurate water testing:
- 30 Self-filling Ampoules
- 25 mL Sample Cup
- Activator Solution
- Ampoule Blank
- Instruction Manual
Accurate Measurement with the PDTS Method
Take the K-3903 DEHA Kit, for example. Designed to measure DEHA levels in water from 0-2.0 ppm, it employs the PDTS chemistry method. In this process, DEHA reduces iron III (ferric state) to iron II (ferrous state), which then reacts with PDTS to form a pink-purple complex proportional to the DEHA concentration. The results are expressed in ppb (ug/L) or ppm (mg/L) DEHA.
Why Test for DEHA?
Dissolved oxygen in boiler system water can cause corrosion and pitting of metal surfaces, leading to inefficiency, equipment failure, and downtime. DEHA (N,N-Diethylhydroxylamine) is added to boiler water as an oxygen scavenger to reduce dissolved oxygen levels. Regular testing ensures the DEHA concentration is sufficient to maintain boiler integrity.
Easy-to-Follow Testing Procedure
- Prepare the Sample: Fill the sample cup to the 25 mL mark with the water sample to be tested.
- Add Activator: Add 2 drops of the Activator Solution and stir to mix.
- Fill the Ampoule: Place the Vacu-vial ampoule tip-first into the sample cup. Snap the tip, and the ampoule will fill automatically.
- Mix the Ampoule: Tilt the ampoule from side to side, allowing the bubble to travel end-to-end.
- Wait for Color Development: Dry the ampoule and wait 10 minutes for the color to develop.
- Read the Results: Insert the Vacu-vial ampoule into the photometer, flat end first, and obtain a reading in ppm.
Safety Considerations
While Vacu-vials offer convenience and accuracy, safety is also paramount. Warning: This product can expose you to chemicals, including chloroform, known to the State of California to cause birth defects or other reproductive harm. For more information, visit P65Warnings.ca.gov.
