Strengths and Purposes of Graduated Cylinders and Beakers

Strengths and Purposes of Graduated Cylinders and Beakers
Graduated Cylinders and Beakers are both common pieces of laboratory equipment. A Graduated Cylinder has a narrow cylindrical shape with each marked line showing the volume of liquid being measured. While they are generally more accurate and precise than laboratory flasks and beakers, they should not be used to perform volumetric analysis. They are also sometimes used to measure the volume of a solid indirectly by measuring the displacement of a liquid. Whatever your use may be, these varieties can handle the task.

Water Aspirators vs Vacuum Pumps

Water Aspirators vs Vacuum Pumps
Water aspirators were once a staple in many biology and chemistry labs but are becoming an increasingly uncommon sight as they are being replaced with vacuum pump aspirators. Water aspirators are designed to connect to a lab faucet and allow water to flow through a tube inside of the aspirator, thereby creating a vacuum. While this type of aspirator is inexpensive and has done a decent job for a very long time, you may want to think about upgrading to a vacuum pump aspirator. Why? Let’s take a close look at the environmental impact, performance, and lifetime cost of a water aspirator as compared to a vacuum pump.

Measuring Water Quality with pH Meters and Colorimeters

Measuring Water Quality with pH Meters and Colorimeters
The proper and accurate measurement of pH is one of the most critical factors in any laboratory procedure. At Next Day Science, we offer pH meters and colorimeters that meet even the most demanding pH measurement requirements. In addition to checking general acidity and alkalinity, our specialized meters measure the pH of silica, chlorine, phosphate, phosphorus, bromine, calcium, chromium, and ammonia, From bench top to portable to pocket pH meters, you are sure to find the right meter for your laboratory needs.
