No minimum free shipping requirement and no delivery charge Defined as the scientific study of all life and draws on theories from chemistry and physics , biology is a very expansive and diverse field.

One way of looking at it is like a kaleidoscope, much like the living organisms themselves. Biologists can study forms of life from completely different ends of the scale, from the smallest of cells to entire bionetworks. We have everything you need when it comes to biology supplies and equipment. From microbiology to human anatomy, the study of biology encompasses a wide range of subjects. EduLab have the largest selection of biology supplies and equipment for use in labs and school biology lessons, you could ever wish for.

We can provide any school, laboratory or research facility worldwide with all the necessary tools. When a large number of samples need to be tested and compared, test tubes are used to make this easier. They are also easily capped with a rubber or glass stopper.

They are generally held in a test tube rack specifically designed for the purpose. If the test tubes become unsafe to touch with bare hands whether due to heat or another reason , test-tube tongs can be used to move them.

It can hold a small amount of liquid or solid. They can be used for evaporation purposes and also can function as a lid for a beaker. A crucible is a small clay cup made of a material that can withstand extreme temperatures. They are used for heating substances and come with lids.

A lab funnel is just like any other funnel except that it was designed to be used in a laboratory setting. They can be made of plastic or glass and can have either a short stem or a long stem, depending on what they are needed for. There are several sizes that can be chosen from based on the amount of liquid that needs to go through them quickly.

This is a primary measuring tool for the volume of a liquid. There are several markings up and down the length of the container with specific increments. Graduated cylinders come in many sizes. The smaller they are in diameter, the more specific the volume measurements will be.

When reading the volume from a graduated cylinder, you will notice that the liquid seems to have an indentation. The liquid around the edges will be higher than the liquid in the center, sloping down like the sides of a trampoline when someone is standing in the middle. This is called the meniscus. Line the lowest point of the meniscus up with the nearest marking, keeping the cylinder level to properly read the volume. A volumetric flask is a round flask with a long neck and flat bottom.

It is used to measure an exact volume of liquid. There is a small line on the neck that indicates how far to fill the bottle use the bottom of the meniscus. They come with special caps that will not let anything in or out. Remember that temperature affects volume; therefore avoid using liquids that will fluctuate in temperature hot water that will cool, for example. These are small glass tubes with narrow tips on one end and a rubber bulb on the other. They suck up liquid that can then be squeezed out in small drops.

These can be used to add an indicator to a solution about to be titrated. There are a large variety of pipettes designed to accomplish specific goals. However, they are all for measuring an exact volume of liquid and placing it into another container.

A buret. These are usually attached with a clamp to a ring stand, as shown in the picture below. A buret is a glass tube that is open at the top and comes to a narrow pointed opening at the bottom.

Right above the bottom opening is a stopcock that can be turned to control the amount of liquid being released. There are markings along the length of the tube that indicate the volume of liquid present. A buret is used for extremely accurate addition of liquid. By adjusting the stopcock, the amount of liquid that is released can be slowed to a drop every few seconds.

Burets are one of the most accurate tools in the lab. To determine how much liquid is added, write down how much is initially in the buret. Then when you're finished adding, write down how much is left. Subtract the final amount from the initial amount and you have the volume of liquid added. The ring stand is used to suspend burets, beakers, flasks, crucibles, etc. Always make sure everything is clamped to the stand tightly.

When clamping glass, be careful not to shatter the glass. Only tighten until snug. When using a ring on the stand, there are usually other pieces necessary to accomplish the goal.
