Apps for the CAT Lab Grinding Mill
Putting lab equipment to multiple uses is a good thing because it increases your lab’s capabilities while minimizing equipment investments. So it is with the CAT Scientific analytical lab grinding mill designed to pair with CAT homogenizer drive motors when tasks call for reducing particle sizes by grinding, chopping, and pulverizing to prepare samples for…
Read MoreBottletop Burette Operating Tips
Bottletop burettes such as the Contiburette® models offered by CAT Scientific are often preferred over glass tube volumetric burettes and pipettes because of their ease of operation and improved accuracy. Moreover they greatly reduce the incidents of operator error and are much easier to clean. Like all precision lab instruments bottle top burets work best…
Read MoreHow to Prepare Linen for Radiocarbon Dating
Radiocarbon dating is a common technique to determine the age of a sample. Dating ancient linen samples such as found, for example, on mummy shrouds is a complex process involving cleaning the sample to remove neutron contamination on the external layers of the fiber. Such contamination skew results and can occur over the years from…
Read MoreHow to Select a Lab Homogenizer
When you invest in a lab homogenizer the more you know about your needs the better your odds on getting the correct model. That’s why we at CAT Scientific developed our online Homogenizer Questionnaire. When you take the time to complete it you will accomplish two valuable objectives: It will make you think seriously about…
Read MoreWhat to Look For in an Entry Level Bottletop Burette
Digital bottletop burettes are precision dispensing tools in many research organizations. A reason for their popularity is ease of use and high precision when compared to volumetric glass tube burettes and pipettes. They are also easier to clean and maintain, and are not nearly as subject to breakage. Labs contemplating the purchase of a digital…

The Chemists Corner is a site dedicated to cosmetic chemists and written by cosmetic chemists. Its mission is primarily helping chemists get employment and being the best chemists they can. Recently while reading much of what’s on Chemists Corner, I thought we might be able to help out a bit with some of the same…
Read MoreThings to Know about Bottletop Burettes
A bottletop burette is a precision dispensing and titrating tool that offers superior accuracy and ease of use compared to volumetric burettes and pipettes. The latter are typically glass tubes with calibration marks on the side. Volumetric burettes have a valve at the bottom allowing researchers to dispense a determined amount of liquid; pipettes are…
Read MoreHomogenizer Configurations for In-Line Processing
Lab homogenizers are versatile tools used to mix, emulsify, disperse, disrupt and otherwise subject materials to a violent action by passing them through what is called a rotor-stator generator. For simplification we’ll say that homogenizers “mix.” Rotors are powered by a drive motor, most of which have controllable speeds. The processing end of the rotor…
Read MoreHow to Sterilize a Lab Homogenizer
Sterilizing is one of several ways scientists can inactivate potentially infectious agents from laboratory equipment such as homogenizers and flow through chambers by the application pressure and steam. The process can be accomplished in a sealed container called an autoclave using, for example, temperatures to 121⁰C and pressures to 15 psi for 60 minutes. Certain…
Read MoreHomogenizing Acidic Solutions
Laboratory and pilot plant homogenizer rotor-stator generators and companion flow through chambers are typically manufactured of nickel stainless steel such as AISI Type 304 and 316. These are excellent alloys for general corrosion resistance and cleanability. With proper care they can provide years of trouble-free service. The same applies for rotor-stator shaft bearings and seals…
