Should I Buy a Manual Bottle-top Burette?

Before nails, bolts, and screws, carpenters had to find other ways to get buildings to stand up without collapsing. Mixing mud or cement takes extra labor, so does carving notches into each and every post and beam. The hammer-and-nail did wonders in terms of saving time, money, and labor. There’s a device that performs a…

Avoid Temperature Overshoot on Hotplate Magnetic Stirrers

 Hotplate magnetic stirrers allow researchers to conduct mixing and stirring experiments at various temperatures to establish optimum processing recommendations for later scale-up. While today’s hotplate magnetic mixers permit close control over temperatures set by lab technicians a malfunction in the unit’s thermostat could result in a potentially dangerous situation should a hotplate temperature overshoot occur.…

How to Achieve Magnetic Stirrer Temperature Control

Setting and assuring solution temperature set points with minimum overshoot when using a hotplate magnetic stirrer in R&D lab and small pilot plant operations is visually demonstrated by using a Pt-100 temperature probe in this video produced by CAT Scientific.  Using MCS78 programmable hotplate magnetic stirrer as a model CAT Scientific’s Steve Gold takes you…

Tips on Selecting a High Performance Overhead Stirrer

Overhead stirrers are highly popular mixing instruments used to blend ingredients in research laboratories and pilot plants.  These units operate by means of motor-powered impellers of different configurations that perform the mixing operation. Being motor powered they can handle samples of higher viscosity than standard or hotplate magnetic stirrers operated with a different technology. In this…

How to Clean Lab Homogenizer Dispersing Tools – Video

Laboratory homogenizers are used in a variety of application, among which are included mixing, emulsifying and dispersing lab samples. Whatever the application one point remains constant: a lab homogenizer must be cleaned before it is used to perform another processing function. This avoids the potential of cross-contamination between samples being processed. Cleaning is particularly critical…

How Dynamic Viscosity Overhead Stirrers Work

Dynamic viscosity overhead stirrers are designed, in slang terms, to “go with the flow.”  What we mean here is that their power systems can accommodate an increase (or decrease as the case may be) of sample viscosity. In this post we’ll take a look at what goes into these precision lab devices and how they…

Understanding Overhead Stirrer Terms

What’s “fuzzy logic?” It’s not a description of the “thinking” that seems to go on in Congress, but instead a term applied to a way technical equipment is automatically controlled.  In this post we list many of the terms you’ll need to know when you shop for an overhead lab stirrer.  Why You Should Understand…

How to Automate Overhead Stirrer Operations

Overhead stirrers are called upon to perform multiple mixing tasks in R&D labs.  When several of these versatile overhead mixers such as offered by CAT Scientific are employed in the lab the researchers’ monitoring tasks are greatly simplified if the equipment is managed by a PC.  This post describes how to automate overhead stirrer operations.…

How to Maintain Laboratory Overhead Stirrers

Laboratory overhead stirrers are one of two widely used instruments to mix ingredients in product research labs. CAT Scientific lab overhead stirrers, also called overhead mixers, have motor-powered stirring tools immersed in the sample beaker*.  The configuration of the stirring tools – generally termed impellers, paddles and blades – is selected based on the task…
