Testing aquarium water, such as freshwater and saltwater (natural or artificial seawater), with reliable instruments is necessary to create a clean and safe environment for your aquatic species.
Maintaining proper aquarium water chemistry is essential for the well-being of fish and other aquatic species. Aquarium enthusiasts utilise saltwater, whether it's natural or artificial seawater, in...
Water testing is important when maintaining a pool or hot tub to make sure the water is safe to be in. The water can end up having too many or too little chemicals in it which can affect the pools hygiene and bacteria levels. The most frequently tested parameters are pH, chlorine (free and total), bromine, alkalinity and calcium hardness. Camlab have created water testing kits for testing thes...
Ever wondered which pH test strips were best in terms of accuracy and usability? Macherey-Nagel have completed a study into their pH test strips against a comparators test strips to help answer this question!
Macherey-Nagel (MN) completed a comparative study with their pH-Fix test strips 0-14 against a competitor manufacturer of 0-14 pH test strips. These pH test strips were tested for thei...
Why is the pH Important?
The correct mix of feedstock such as slurry, food waste and processed plant material is important to ensure efficient biomethane production.
This combined feedstock (media) is broken down by microorganisms in a series of steps, resulting in the production of methane (methanogenesis).
The pH of the media is an important consideration during this process. Values...
Hach have just launched their new HQ meters - a range of robust portable electrochemistry meters ideal for use in the field and beyond. Models are available with up to three input channels and have advanced features that you would not normally find in a portable meter.
The HQ range by Hach are robust, portable electrochemistry meters.
Features
Simple and easy calibration - most measur...
pH in simple terms, is a measure of how acidic or alkaline something is. It is measured on a logarithmic scale of 0-14, where 0-6 is considered acid, 7 is neutral and 8-14 is alkaline. Using test strips and papers is the simplest way to quickly measure pH. Although basic, they are ideal for many applications and are also suitable to use as an indication prior to more accurate pH testing (i.e us...
The Ultrameter II 6PIIfce from Myron L is a versatile, fully waterproof multi-parameter meter, which can measure the following parameters: conductivity, TDS, resistivity, pH, ORP, free chlorine and temperature. The ultrameter has many applications including pool monitoring and measuring the conductivity of ultrapure water.

Conductivity (also called electrical conductivity or EC for short) is a measure of a substances ability to conduct an electrical current and this can be measured using a conductivity meter. In the farming and the agriculture industry, conductivity can be used as an indicator of overall soil nutrient levels.

The FOS/TAC ratio is a commonly used indicator for assessing the fermentation process within biogas reactors, where FOS is a measure of the volatile organic acids (measured in mg CH3COOH/l) and is TAC is a measure of the total inorganic carbon i.e. the alkaline buffer capacity of the system (measured in mg CaCO3/l). In simple terms, this ratio looks at acid vs alkaline in the system which helps...
In the food industry, pH monitoring may be required during the production or pre-production process for a number of reasons including for microbe monitoring and taste purposes. In baking and bread-making there are a number of reasons why you would wish to know the pH - having a low pH in sourdough inhibits growth of pathogenic bacteria and in bread dough pH control agents (preservatives) may be...

Many pH meters also have a separate reading range which gives results in mV. This can be used for a range of applications.
1.) Checking your pH electrode calibration. Most meters automate the calibration of pH which makes it simple to perform and ensures consistency in results. However, when issues ar...
Camlab provide a wide range of non-bleeding pH Strips from Macherey-Nagel, as well as our own great value range. The Camlab range of pH indicator sticks are great value, non-bleeding pH indicator strips for rapid reading of weakly buffered or strongly alkaline pH solutions. Advantages: •Unlike conventional pH papers the indicator dyes used in these Camlab test sticks are fixed to the cellu...
Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
