Whilst most commonly associated with the monitoring of biochemical oxygen demand (BOD), the OxiTop system can be used for many types of respirometric testing including OECD biodegradability tests, soil respiration and biogas testing. The classical OxiTop heads have been around for many years and are tried and tested. This year, they have been modernised with two new groups of heads being releas...
Turbidity measurements are of extreme importance in quality monitoring in water, wastewater, beverage production, electroplating and petrochemical applications. Light passing through a liquid that contains undissolved solids, such as algae, mud, microbes and other insoluble particles, is both absorbed and scattered. Turbidity increases with the amount of undissolved solids present in the sample...
WTW has developed an innovative reagent free system to measure COD, Nitrate and Nitrite without the need for vials.
The OptRF system is built in to some of their spectrophotometers, and provides calculation of the results based only on absorbances in the UV wavelength range.
However, this system is only applicable to some samples and should be evaluated before changing from traditional CO...
Offering the unique combination of photometry, pH and turbidity measurement the pHotoFlex Turb by WTW consists of a compact and easy to use device for water analysis. This robust unit, ideal for the field, fits the spec of an everyday-use photometer but with the added option of using an infra-red light source for nephelometric turbidity measurements and adding a pH probe. We were ...
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...
