A magnetic stir bar, also known as a flea, is typically made of a small magnet coated in PTFE (Teflon) or plastic. The coating is intended to be chemically inert so as not to react to the mixture the stir bar is immersed in. This component is not very large, and ranges in size from a few millimeters to a few centimeters.
A magnetic stirrer DF-101S (Zhengzhou Greatwall Scientfic Industrial And Trading Co., Zhengzhou, China) with a maximum stirring speed of 1,250 rpm was em- ployed for stirring the sample during extraction. Microdetermination of phosphorus from infant formulas, casein and casein phosphopeptides.
A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic field. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example. A magnetic stirring system generally includes a coupled heating system for heating the liquid (Figure 6.5).
A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (or flea) immersed in a liquid to spin very quickly, thus stirring it. ...

Feb 23, 2007 We investigate the flow generated by a magnetic stirrer in cylindrical containers by optical observations, particle image velocimetry measurements, and particle and dye tracking methods. The tangential flow is that of an ideal vortex outside a core, but inside downwelling occurs with a strong jet in the very middle. In the core region dye patterns remain visible over …
Hotplate Magnetic Stirrer LHST-A20 is a compact, tabletop device having magnetic stirrer with heating function, oﬀers rotating speed of 100 to 1200 rpm. Designed with round glass ceramic top plate and octahedral stir bar provides maximum set temperature of 450˚ C. With USB port interface and timer, memory function for stirring speed and setting
Hotplate magnetic stirrers are used for organic synthesis, extraction, analysis of oil products, pH-measurements, dialysis, soil suspending, preparing buﬀer solutions etc. across the ﬁeld of chemical engineering, microbiology, pharmaceuticals, geology, scientiﬁc research etc.
Magnetic heating stirrer is usually suitable for the heating of beakers, flasks, crystallizing dishes and other containers and the mixing of samples. In chemical synthesis laboratories, however, it is often ... Sealed outer shell and isolated critical parts design for enhanced longevity even in a harsh laboratory environment.

May 22, 2010 this is a nice idea of a magnetic stirrer. I use it in labs to mix solutions, i'm also making a centrifuge and a PCR machine and off course magnetic stirrer. let me tell you that magnetic stirrer you want could be of two types. one rotating and other shivering. the rotating type is good to make, but a little costly than the shivering and ofcourse better and preferred. …
Nov 10, 2021 Di era modern saat ini, hotplate stirrer yang digunakan sudah terdapat magnetic stirrer didalamnya. Seperti gambar yang tertera di atas, dapat dilihat bahwa di sebelah kanan pengatur suhu. ... Bagian Bagian Isolated Organ Bath – Halo pembaca artikel alat laboratorium, pada artikel kali ini penulis akan membahas artikel pendek berjudul ...
Oct 07, 2020 First, we have to choose the isolated terpene or terpene profile that we’d love to try and get a glass jar. After pouring the distillate into the jar, we should add one to two drops of terpenes per gram of oil. Before letting the mixture infuse overnight, we have to stir it well. For that, we can either use a dabber or a magnetic stirrer.
The Flinn Hot Plate/Magnetic Stirrer has excellent chemical resistance, high impact strength and an unsurpassed flat ceramic surface. An electrical input controller provides fine temperature control from ambient temperature to 540 C. You can reach a rapid boil in just eight minutes—twice as fast as comparable hot plates! The square top is isolated from the die-cast …
The Flinn Hot Plate/Magnetic Stirrer is a state-of-the-art device. The space-age ceramic top has excellent chemical resistance, high-impact strength and an unsurpassed flat surface. The flatter the surface, the better the heat transfer. An electrical input controller provides fine temperature control from ambient temperature to 540 C.
The RET control-visc is a magnetic stirrer whose remarkable technical functions have been develo-ped for demanding applications. The unit mainly focuses on three core competences: 1. Safety, 2. ... Isolated drain Protection class IP42 C Mode advantages Protected against changes to set values Values are still fixed after restarting
This magnetic stirrer is the lab equipment to mix liquid, mainly used for stirring or heating at the same time liquid of high viscosity or solid-liquid mixture. Its basic principle is repulsive for like charges and attractive for unlike charges. ... One-time injection molding shell is beautiful, corrosion-proof and isolated. Built-in PID ...
To test the hypothesis that both method based errors as well as internal lab errors can influence the accuracy and precision of the magnetic stirrer method for pooled sample digestion (MSM), we initiated a study to evaluate the analytical uncertainty of the MSM.
Trapezius muscle injuries often occur in conjunction with high-grade acromioclavicular joint injuries , but to our knowledge, isolated trapezius injuries have not been described in the literature. We present a case of isolated trapezius strain in a spastic patient with multiple sclerosis documented with magnetic resonance imaging (MRI).
Using a mixer mill at an oscillation frequency of 20 Hz with solid samples of alkenoic acid 1a and NBS, 14% of lactone 2a was produced in 10 minutes (Table 1, entry 1).When the reaction was conducted in dichloromethane, only 10% of 2a was detected even after 2 hours (entry 2). No reaction was observed when the solids of 1a and NBS were mixed using a magnetic stirrer …
