Agriculture analysis is an essential aspect of crop growing. Understanding the soil's current nutrient levels is crucial to increase quality and yields.
LaquaTwin's range of portable meters provides in-field analysis for pH, conductivity, sodium, potassium, nitrate and calcium levels.
The example below uses the LAQUAtwin nitrate and...
Testing of ground and surface water is a key part of routine testing for water companies. Depending on the need, a number of different parameters are often assessed. The Horiba LAQUA range has a meter specifically designed for this type of analysis.
The U-50 series of multi-parameter meters enables the simultaneous measurement and monitoring of up to 11 parameters with one ...
All plants need calcium rich soil to grow. The calcium is used by the plant in developing the plant cell walls and membranes. Furthermore, it is a non-leaching mineral (it will stay in the soil) and will improve water penetrability and reduce soil salinity. It is thus helpful to determine the amount of calcium contained in soil. Generally, Atomic Absorption Instruments (AA) or Inductivity Coupl...
If not prepared properly there is a potential risk that sushi rice will develop bacteria, parasites, and viruses harmful to human health. One of the aspects that must be measured and controlled in preparation of sushi is the rice pH. If the rice has a pH less than 4.5 this will prevent bacteria growth and toxin production. This pH is lowered by the addition of vinegar and salt. ...

Sodium is a mineral required by the body for normal functions, but excessive intake can cause high blood pressure and hypertension. This has lead governments and regulatory bodies to focus on monitoring the levels of salt in foods in order to reduce the risk of these health affects. Canned foods are of particular concern as these often contain relatively high levels of salt. The Horiba La...
Seawater has an average salinity of 35 ppt = 35 parts per thousand (equivalent to 35,000ppm or 3.5%). However the salt level does change depending on rainfall, evaporation, ice thawing or rivers, so the salinity can vary over areas, time or seasons. Camlab can offer two handheld meters which quickly and directly measure salinity up to the high levels required for seawater. [caption id=...
Measuring pH in food is a useful indicator of consistency over batches for quality control but can also be used to monitor foods where the pH changes over time - for example in yogurt production, brewing or to test the freshness of foods. Standard pH electrodes will often struggle when used in food samples, as the reference junction becomes blocked the reaction time will get slower and event...
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...
