As of June 2022, Cole-Parmer have undergone a rebrand of some of their brands and equipment in order to be more efficient. The units themselves have remained the same but the design and model numbers have been updated to fit the Cole-Parmer theme. Below is a list of some brands that have been rebranded and an overview of their new model numbers.

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...
Flame photometers function on principle of atomic excitation and de-excitation followed by light emission to measure the levels of particular elements (including K, Na, Li, Ca and Ba). Over particular ranges, the intensity of the light emission is directly proportional to the number of atoms of that type present in the sample. Also known as flame atomic emission spectroscopy, it is a branch of ...
If you're looking at new lab equipment or instruments, you will probably shop around and research the options before you buy. But how can you get a more in depth feel for the products before you buy?
Jumping straight to a live demo of the equipment is not always the best way - this can delay the process if you need to wait for an appointment, so there could be faster ways of getting the info...
The team at Jenway have described a method to determine calcium level in milk samples using their PFP7 Flame Photometer. Calcium is usually present at about 120mg per 100ml milk, or 0.11%, but this varies with the type.
The method and equipment required are summarized below to test milk samples for calcium content.

To replace the very popular Jenway 370 handheld pH meter, two new models have recently been released.
[caption id="attachment_10353" align="aligncenter" width="621"] The Jenway 370 (left) has now been replaced by the Jenway 550 (centre) and the Jenway 570 (right) pH meters[/caption]
The Jenway 550 and 570 models offer the same portable, flexible and low cost handheld meters we expect, wit...
Soil is a mix of organic matter, minerals, air, liquids and other organisms. It is vital in supporting life on Earth by allowing plant growth as well as storing, supplying and purifying water. As rocks break down into particles of sand, silt and clay mineral particles are released and they are then available to support plant life. It is important to determine the amount of potassium naturally a...
How can I measure the caffeine content in drinks? Caffeine is a naturally occurring molecule found in various plants worldwide, and found in beverages such as tea, coffee and soft drinks. [caption id="attachment_9540" align="aligncenter" width="290"] A wide variety of drinks contain caffeine - UV spectroscopy allows you to measure the amount present[/caption] The amount of caffeine present i...
Spectrophotometers are relied on by a wide range of laboratories, for tests ranging from specific parameters, like chlorine or metals concentrations, right through to complex analyses of reaction kinetics. When choosing a spectrophotometer the range of specifications and price is vast, so take the time to list the features you need before you buy and make sure you choose the right one. [c...

Jenway are pleased to announce the introduction of two new micro-volume conductivity probes into the range. Following several inquiries for narrow conductivity probes to measure either small volume samples or samples in small vessels, we are pleased to be able to offer a 4mm and 6mm diameter probe to m...
A question often received by the Technical Support team is what to do if the flame goes out after the ignition switch is released. If you find this is the case, first of all please ensure the burner is the correct way round with the flat side pointing up and the cone pointing into the mixing chamber. The correct orientation is shown in the Fig. 1.

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...
