Ohaus Guardian series of hotplate stirrers consists of the 2000, 3000, 5000 and 7000 series. The uses range from being ideal for educational and laboratory applications, to research, academic and industrial applications. This blog will go over their Hot Top Indicator to help increase safety in the lab.

There are many things that can influence the weighing accuracy of a balance. One aspect that can be overlooked are environmental influences. These typically include: temperature, humidity, air-flow, electrostatic charges and vibrations. Here we will outline how these factors may influence readings and possible solutions to overcome these.

Fluctuating temperatures can influenc...
A moisture balance (also known as a moisture analyser) is an instrument that measures the moisture content of a sample. This is done by weighing the sample, then heating it to remove moisture and finally weighing the sample again. The final weight is subtracted from the starting weight and the difference in values is the moisture content. While easy to use, the setup and method development can...
A vortex mixer is a piece of laboratory equipment that is used in the rapid mixing of samples. This type of mixer has a small footprint with a high rpm. Vortex mixers can be used in any laboratory but is mainly used in microbiology, biochemical, bioscience, and analytical laboratories. Vortex mixers mainly mix samples/reagents but they can also be used to suspend cells.

There are many options out there when it comes to laboratory balances. Other than the maximum capacity, one of the main differences you may have seen between balances is their readability. The term readability is often used interchangeably with terms like repeatability (precision) and accuracy. However, they each have different definitions that are important when trying to understand the differ...
Water is essential to life; it plays a critical role in the physical and chemical functions of our bodies, the food we eat, and the materials that surround us. In many industries and industrial processes it is important to measure the water content of substances in order to assess quality. This allows us to adjust manufacturing processes and ensure that products and foodstuffs meet the c...
Moisture balances offer a fast way to analyse the moisture content of food samples, and are ideal for quality control checks during production or before final product release.
However some of the balances contain glass parts, which presents a hazard in food manufacturing areas.
We've found two moisture balances that do not contain any glass, making them suitable for food production areas....
Suspended solids is widely used as an indicator of water purity, particularly in discharge consent. When testing by the full gravimetric method, a balance, oven and desiccator are required to thoroughly dry the isolated solids until a constant weight is found. (For more details on this, see our previous post about the difference between gravimetric testing and other methods.) It may be te...
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...
