Do you have a Hach DR900? Have you lost the ability to view and access it's stored programs?
There is a potential for the Hach DR 900 to lose the ability to view and access its stored programmes. This is a result of the internal data log overwriting the stored programme file. This will most likely occur on instruments that have performed in excess of 1,700 tests. In addition, th...
Hach have released the following statement around a temporary change to the printing on packs of their powder pillows.
The manufacturer of the ink used on powder pillows has a component shortage, caused by a Covid-19 supply chain issue. This is temporarily affecting what is printed on powder pillows. Pillows now temporarily have only the product identifier (i.e.) M# printed on them.

As of April 2021, Hach have implemented a design changed to their 16mm COD supplied in Europe. These are beginning to hit the supply chain now so you may notice a difference in your tubes.
The main changes are as follows:
The updated 16mm COD vials will have a round bottom to the cuvette with a larger opening simplifying handling and pipetting of your sample. Reagent formulations, calib...
Let us first look at the probe. The Hach dissolved oxygen probes are equipped with a measuring LED that emits a pulse of blue light and a photodiode as a light detector. The probes are also equipped with a sensitive luminescent coated spot that is exposed to the sample.
The measuring LED emits a pulse of blue light which irradiates the back of the oxygen-sensitive spot. The coating mate...

Turbidity is a measure of the cloudiness of water and is used as a key water quality indicator. This can then be used to quantify the amount of particles disrupting light passing through a liquid. For example, muddy water has a lot of small soil particles. This disrupts light going through it and makes it very cloudy and turbid. However spring water tends not to have many particles in and so is...
SpecCheck standards are solid gel secondary standards produced by Hach. They are for use with their photometers. They are presented in sealed glass cells, so they are ready to use out of the box, with no preparation. Within each pack of standards, 4 vials are provided. One is a blank along with 3 coloured gel standards. They are available for a number of parameters including chlorine...

The DR300 by Hach is a robust, portable single parameter colorimeter. It is the follow on from the Pocket colorimeter II which has been discontinued for most parameters - offering improved waterproofing, a large display and ergonomic design combined with optional Bluetooth and system integration. This unit is available in two formats – a single wavelength (either 500, 528, 600, 655nm) or pre-pr...
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...
