Your Guide To Different Types of Laboratory Stirrers

There are many different kinds of stirrers available to be used in the laboratory. Each stirrer comes with a unique quality that makes it suitable for a specific application. Here are the different kinds of stirrers available and what they are used for.

Magnetic Stirrers

Magnetic stirrers employ a rotating magnetic field that causes a stirrer bar of a flea, which is submerged within a liquid, for spinning, and hence, stirring. Generally, magnetic stirrers are suitable for stirring small volumes of liquids with low viscosities. There are models, however, that have been designed to handle high viscosity and volume.

Magnetic stirrers usually have ceramic or stainless steel plates.

Stirrer Hotplates

Stirrer hotplates combine a stirrer and a hot plate. Both functions can be used independently or together.

There are many types of stirrer hotplates, but the main difference is the material used for the top plates:


The chemical resistance of ceramic top plates makes them ideal for use with corrosive chemicals that might splash onto the plate surface. Their higher temperatures can reach around 450°C and they are easy to clean.


In comparison with ceramic plates, aluminum top plates are more robust and are more resistant to accidental knocks.

Overhead Stirrers

An overhead stirrer comprises the stirrer, rods, paddles, and stands, and is generally more durable than a magnetic stirrer.

They are most commonly used for large volumes or viscous solutions.

A variety of paddles can create different stirring motions that are suitable for different applications:

  • Paddle
  • Centrifugal
  • Turbine
  • Dissolver
  • Propeller
  • Anchor

Specialty Stirrers

Submersible Stirrers

Submersible stirrers are sealed stirrers that are used for being submerged in water or oil, as well as being used at a wide range of temperatures. They are ideal for being used in water baths, ovens, incubators, etc.

Biological Stirrers

Biological stirrers are designed specifically to stir biological samples, like cell cultures. They offer gentle and heat-free stirring and are free from dust and germs.… Read More...

March 22 (Reuters) – Nvidia Corp (NVDA.O) on Tuesday introduced new chips and technologies that it reported will boost the computing velocity of significantly complex artificial intelligence algorithms, stepping up competitiveness versus rival chipmakers vying for lucrative data heart small business.

The corporation offered details of new graphic chips (GPU) that will be at the main of AI infrastructure, releasing the H100 chip and a new processor chip named the Grace CPU Superchip, centered on British chip company Arm Ltd’s know-how. It truly is the initial Arm-based chip from Nvidia to be unveiled considering the fact that its deal to purchase Arm fell aside final thirty day period.

Nvidia also declared its new supercomputer “Eos”, which it reported will be the world’s swiftest AI method when it commences procedure later on this 12 months.

The military’s newest robot technological innovation desires to make your salad

At Travis Air Pressure Base, in Fairfield, Calif., the U.S. armed service has just set up a new piece of robotic engineering. It is not a killing machine, or a piece of armor, or even definitely everything connected with war or protection. The new robot makes salad.

Perched on a counter surrounded by tubs of components in the base’s eating corridor, the robotic swivels all-around and grabs utensils with 1 arm, scooping lettuce and tomatoes into a bowl in the other. It is automating a comparatively uncomplicated kitchen responsibility in a cafeteria that consistently serves hundreds of men and women a day—and is beginning to present how kitchens of the upcoming could be reshaped by robotic cooking technology.

The salad making robotic is known as Alfred, and it was built by Dexai Robotics. The corporation just acquired a $1.6 million deal with the Office of Protection to put in 10 Alfreds in army dining facilities about the U.S. Its very first, at Travis Air Force Base, produces salads for seize-and-go food items provider for the base’s active obligation staff.

“They have about a thousand men and women that arrive as a result of there a day. So they’re serving a lot of foodstuff to hungry folks,” says David Johnson, Dexai’s cofounder and CEO. The Alfred robotic is a way to speed up the process of serving these individuals. It is also a way to fill in a labor hole.

“When we initially commenced [the company], there was a enormous labor trouble now in the market, and this was two to 3 a long time ago,” claims cofounder Anthony Tayoun.

WHO performs to unfold COVID vaccine technological innovation to a lot more nations

GENEVA (AP) — The Globe Overall health Business is generating a international teaching heart to assistance poorer nations around the world make vaccines, antibodies and most cancers therapies utilizing the messenger RNA technologies that has properly been made use of to make COVID-19 vaccines.

At a press briefing in Geneva on Wednesday, WHO Director-Normal Tedros Adhanom Ghebreyesus stated the new hub will be in South Korea and will share mRNA technologies currently being created by WHO and companions in South Africa, wherever scientists are performing to recreate the COVID-19 vaccine created by Moderna Inc. That hard work is having put devoid of Moderna’s help.

“Vaccines have aided to alter the training course of the COVID-19 pandemic but this scientific triumph has been undermined by vast inequities in accessibility to these existence-conserving instruments,” Tedros claimed.

It’s the first time that WHO has supported these kinds of unorthodox initiatives to reverse-engineer a commercially-offered vaccine, earning an stop operate close to the pharmaceutical marketplace, which has mostly prioritized supplying abundant countries over poor in the two revenue and production.

Both equally Moderna and Pfizer-BioNTech, makers of the two approved mRNA COVID-19 vaccines, have declined to share their vaccine recipe or technological know-how with WHO and its companions.

WHO mentioned the shared know-how would with any luck , outcome not only in coronavirus vaccines, but would also be useful in making antibodies, insulin and treatment plans for health conditions including malaria and most cancers.

WHO’s main scientist Dr. Soumya Swaminathan estimated that the attempt to recreate Moderna’s vaccine would in all probability not generate any usable shots right until late next yr or even 2024, but mentioned that timeline could be shortened considerably if the maker agreed to support.

The world disparity in entry to COVID-19 vaccines is great. Africa at this time produces just 1% of the world’s COVID-19 vaccines and only about 11% of its population is immunized.
