The height you set the sash of your fume hood at has an impact on many different things. First and foremost, and the purpose most people associate with the sash height, is that it must be set low enough for proper fume extraction to maintain safe, breathable air throughout the lab. Although the sash height is the determining factor for this, there are a lot of other things that need to be taken into consideration when determining the proper sash height.

Have you ever had trouble locating a sample you need from your labs freezer(s)? Are you running out of space? Whether you are currently experiencing any of these problems or you are looking for ways to get organized so you won’t have storage problems in the future, you’ll be pleased to learn about all of the options that are available to meet your needs.

HPLC is widely used throughout the Biological Sciences. It is used by Biochemists to purify peptides and proteins and used by Molecular Biologists to isolate nucleic acids, oligonucleotides and plasmids. It is also widely used in the biotechnology fields. For most biological samples, reverse-phase HPLC is used. Reverse-phase HPLC consists of a polar mobile phase and an apolar stationary phase.

Welcome back for the second article in our 3-part series about High Performance Liquid Chromatography (HPLC). If you’d like to read the first article, you can find it here. It covers the principles behind HPLC and explains how the most commonly used types of HPLC work. This article focuses on the chemical applications of HPLC and it will explain why HPLC is used so widely in pharmaceutical and food based research. If you’re in the biological sciences, don’t worry, our next article will cover the biological/life science applications of HPLC.

High Performance Liquid Chromatography (HPLC) is a widely used analytical technique that many industries and research fields rely heavily on. In this article you will learn how HPLC systems work and the different types of HPLC machines that are commonly used. This article is the first in our series about HPLC’s and its purpose is to give you a general overview of HPLC systems.

Ultrasonic equipment usage has spiked in recent years in many different fields of research including chemical, biological and engineering. There are a variety reasons for the increased use of the different types of sonication equipment that you may find beneficial for your own experiments. In this article you will learn how the various types of sonication equipment are being used in research today, learn how they work and learn how they can be useful for your research.

The dynamics of a cell culture process are very fluid in nature and its success relies on many different factors. When you have everything set up optimally for your specific requirements the process is more productive, allowing you to focus more on your research. In this article you’ll learn about the factors and conditions that affect the cell culturing process and how you can optimize the parameters to enhance your research.

Hopefully you’re here because you either have an application that requires the use of a centrifuge, or you are looking to purchase a centrifuge but you’re not quite sure which type will best meet your needs. If this sounds like you, then you have come to the right place. After reading this concise yet informative article you will gain an understanding into the different types of centrifuges available, why they are useful and how they work so you’ll have the information you need to choose the best design for your laboratory experiments.

Did you know that it's been 20 years since the birth of Dolly the cloned sheep? Dolly's story made headlines worldwide and stirred some very passionate (heated) debates as it entered the history books, forever altering the future of life as we had known it prior to that. Whether you remember Dolly the cloned sheep or not, read on to find out why she was so important, what happened to her and how the cell reprogramming techniques that created Dolly have led to life changing advancements. All of which were made possible by the groundbreaking research that created Dolly.

Want to know more about cell culture environments and how you can benefit from the plethora of advantages available to you when you cultivate under hypoxic conditions? After reading this concise yet informative article you will gain an understanding of the factors that plague traditional cell culturing and how using hypoxic conditions to cultivate cells will benefit your research by reducing these factors.

To get accurate measurements when you are working with samples that have a low concentration of protein or DNA molecules you’ll need to fully understand the specific fluorescence and absorbance techniques used to measure low quantities of DNA and proteins in order to determine which method is best suited to meet your needs.

Ducted Chemical fume hoods work by extracting air and noxious fumes away from the user and out of the fume hood where the air is filtered and returned to the outside environment by means of a duct system. In this article you'll learn about the different types of fume hoods which are categorized by their air flow properties.

Laminar airflow cabinets (or laminar flow hoods) work by controlling particulates that would otherwise contaminate your work. Removal of particulates provides a sterile, dust-free work area. There are two different types of laminar flow cabinets, which is determined by their directional airflow properties: Vertical laminar airflow hoods and horizontal laminar airflow hoods. Laminar hoods are currently used over a range of industries from medical research to electronics.

Microvolume Spectrophotometers not only allow researchers to do more with less, they allow for faster and more accurate results as well. DNA, RNA and protein quantification has been truly revolutionized by Microvolume Spectrophotometers when compared to the previous spectrophotometer technology available that requires the use of cuvettes or capillary tubes to house samples for testing.

Looking for safety equipment for your laboratory to prevent contamination? Biological Safety Cabinets, Fume Hoods or Laminar Airflow Cabinets? Find out about the different types of hoods and cabinets, what each of them are designed to protect against, their individual features, and the advantages and disadvantages of each of them.

On February 4th, 2016 Steve was involved in a serious snowboarding accident that left him with the substantial brain trauma. Steve passed away from his injuries on February 10th, 2016.

Choosing between the long-term storage benefits that liquid phase LN2 freezers provide and the ease of access that vapor phase LN2 freezers provide can sometimes be difficult. However, if you want to have frequent access to your samples (which will expose your samples to temperature fluctuations anyway) then a vapor phase system will make retrieval easier and much safer.

Biological safety cabinet classes are each responsible for varying levels of protection that safeguard you, your work and the environment against noxious elements and contaminants. Classes are dependent on the hazardous level of potential contaminants you and your work are vulnerable to.

Modern laboratory biology is to a large degree a science of the small. Many important operations take place in the “almost-microscopic” domain. For operations in that domain – dissections, probe construction, etc. – an eyepiece-less stereo microscope can be a very valuable tool.
