Magnetic Stirrer Bar Oval Octagon Cross Star Gear Cylinder Shape for Mixer Stir + Magnetic retriever (White Color, 8 pcs)

Mixed shape creates more turbulence and a stronger vortex..
It is used to stir a liquid or solution in biological, chemical, medical and research laboratory applications..
Teflon (PTFE) casing is chemically inert, can be used with corrosive chemicals, and helps reduce friction and wear while spinning.
Built-in pivot ring helps reduce vibration and wear during stirring.
The stir bar is placed inside a container of liquid or solution that is seated on a magnetic stirrer, which is a laboratory device that creates a rotating magnetic field using a rotating magnet or multiple stationary electromagnets..

Koolance 702 series coolant is used by many industries requiring a high performance, low-toxicity, reliable coolant with corrosion and biological inhibitors..
A high quality coolant is extremely important for addressing dissimilar metals and biologic growth (bacterial and algae) long-term..
Koolance liquids will not clog components and can typically be used for 2-3 years before replacement is recommended..
(Coolant shelf life is 3 years.) This container includes 700ml (24 fl oz) of prediluted coolant and can function as a squirt bottle for convenient reservoir filling..
It’s recommended to replace the coolant at least every 2-3 years, or immediately if there is any change in color or clarity..

Clears pond water with natural bacteria and enzymes.
24 water soluble packets treats 2,000 gallons for up to 4 months.
Seeds and maintains biological filters keeping your pond healthy and balanced.
Concentrated formula, safe for all aquatic lifeDescriptionCrystalClear Biological Clarifier, also known as BioClarifier naturally clears water, removes odors and breaks down suspended dead debris and decaying leaves with billions of bacteria colonies and added enzymes. The natural bacteria enzymes seeds biological filters to maintain a healthy pond ecosystem. The result is a cleaner pond, healthier fish, improved dissolved oxygen levels and reduced ammonia levels. CrystalClear Biological Clarifier comes in easy to use water-soluble packets and can be used in ponds, fountains, bubblers and disappearing waterfall features. Use when water temperatures are above 50 degrees F. 24 packets treats up to 2,000 gallon pond for up to 4 months. Product may come as Biological Clarifier (green label) or BioClarifier (blue label), however it is the same product..

Aquascape BioBalls Biological Filter Media supports effective biological filtration by providing textured surface area for beneficial bacteria to grow and colonize.
Each ball offers 19 square inches of surface area, and the center channel allows the balls to be strung together, making cleaning quick and simple.
BioBalls Biological Filter Media will not break down like traditional biological media options, providing years of trouble-free use without replacement..
The paddle wheel design breaks water flow, helping to de-gas the water and maximize dissolved oxygen levels..
Compact size allows for placement into smaller spaces and each 100 count includes a media net with drawstring..

Used to stir a liquid or solution in biological, chemical, medical and research laboratory applications,it works very great in the flat bottom container.
With acid and alkali resistance, resistant to a variety of organic solvents, almost insoluble in solvents.
With the smallest surface tension in the solid material, no adhesion to any substance.
the lowest coefficient of friction in solid materials..
The stir bar with recessed bezel helps to reduce vibration while stirring.Particularly Useful for Environmental Testing and Life Science Applications in Which Small Sample Volumes Need to be Prepared and Evaluated.
Provides a larger surface area and added turbulence when the smooth surface of the cylindrical rods compared.
