The phenomenon of measurement drift can occur and adversely affect analytical balances when weighing compounds. Read on for our guide on how to prevent this!
Need to get a handle on the fundamental differences between HPLC and GC to pick one for your studies? Here’s a quick explainer!
Do you need to learn about gas chromatography? This article takes you through the basic principles and instrumentation. With illustrations!
In biosciences, we purify our target molecules using chromatography. So, we need a thorough understanding of how chromatography works!
A neglected pH meter means less reliable experiments, poor reproducibility, and your time wasted. So, learn how to use a pH meter correctly!
Purchasing a microscope camera is one of the most daunting tasks you might have to undertake. Before you set out to buy that camera, carefully consider your applications. Things like sample brightness or the speed of the phenomenon you are trying to capture can dictate your choices. Also, this is the time to make peace…
While using human clinical samples in your research can provide robust and heterogeneous results applicable to larger portions of the population, working with these samples presents its own set of challenges. Here are some tricks I have learned to help isolate and grow your cells of interest while eliminating stromal, blood, or other undesired contaminants….
In my last article, I discussed how to best keep your lab’s HPLC running smoothly. However, even the best-maintained HPLCs and columns need periodic cleaning. Today, I’ll describe how to identify and troubleshoot a clogged HPLC column. Columns Are Finite First of all, it’s important to realize that columns do have a finite lifetime. The…
You have probably run a standard agarose gel hundreds of times. They are great for visualizing small DNA fragments up to 10 kb, but what if you want to examine really large pieces of DNA or even whole chromosomes? This is where pulsed field gel electrophoresis (PFGE) comes in! While the equipment required to run…
If you’re anything like me, your biggest lab fear is working with expensive equipment prone to damage. HPLC is a wonderful tool, capable of separating, identifying, and quantifying a vast array of compounds, but it requires an attentive scientist to properly handle and maintain each component. In this article I’ll describe a few basic handling…
Fourier Transform Infrared spectroscopy (FTIR spectroscopy) is a useful and exquisitely sensitive technique used to identify and quantify unknown compounds, as well as study fine molecular details. However, to obtain a meaningful IR spectrum, it is not only important to prepare the sample correctly but also to learn how to clean the apparatus that houses…
Here’s a few things to take into consideration when starting up a new lab. Starting anything new is understandably overwhelming, but let’s break it down and go through the main points of designing your own laboratory. Purpose of Your New Lab The purpose and function of your proposed lab sets the course for the tasks…
Rust spots provide a good shelter for bugs, which will get there one day, and from the rust into your tissue culture. Here’s what you can do to deal with the problem as soon as you see it.
There are some wonderful toys in the lab that enable us to open up a whole new world in science. One of those is a rather pricey and an incredibly sensitive laser-based apparatus capable of counting and sorting cells, detecting biomarkers, and engineering proteins: the flow cytometer. By propelling cells through the path of the…
You had been happily measuring your DNA samples with your NanoDrop for a while, until… you noticed that your results are not reproducible *gulp*.
Read on – here are 10 points that will help you troubleshoot the issue.
When you first start out using a microscope, you might only adjust the eye pieces, objectives, and the focus controls. However, you shouldn’t overlook the microscope condensers as they are an important part of the whole optical system of a microscope.
A new lab toy to make it big in the last 5–10 years is the Accuri C6 cytometer (now under the BD umbrella), a low-cost instrument in comparison to the big boys. Lightweight, with a small footprint and straightforward maintenance, it’s often the cytometer of choice. It may be suitable for those labs that require…
