Borosil brand pipettes are manufactured from specially selected heavy-wall machine-drawn borosilicate accurate bore glass tubing. They have precision formed jets and bevel ground ends to resist chipping. The graduation marks are in durable white enamel or amber stain, both are resistant to normal laboratory agents and repeated washing. All the pipettes are individually measured and then marked. Accuracy is ensured between any two readings, because of uniformity of bore. The pipettes can be autoclaved and if necessary can be flamed for sterilization.

Natural resources are created by Earth's processes and used as a source of energy for all life on Earth. While some are created over the course of millions of years, others are continually generated each and every day. In Natural Resources, students will examine both renewable and nonrenewable resources, touching on their sources and many uses. Discover the best methods of conserving nonrenewable resources, including how they are recycled and cleaned. A fun, hands-on investigation illustrates how students can observe the many different kinds of particles that can be found in the air, while a geothermal plant provides the setting for a look at how people can turn volcanic heat into electricity. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
