Clamps and ring stands are used to hold glassware and apparatuses in place. For example, clamps are frequently used to hold round-bottom flasks, condensers, thermometers, addition funnels, etc. Ring stands may be used for larger diameter items, including separatory funnels, filter funnels, wire gauze etc.
Clamp stands are use to hold, for example, glass flasks, test-tubes, and other apparatus commonly used in a laboratory.
The term pcr in biology stands for polymerase chain reaction. It stands for a process that biologists use in DNA sequencing, allowing them to make DNA copies more efficiently.
I went to the nail salon and asked them to push back the cuticle on my ring finger.
your middle finger If your vagina is wide enough use two fingers(i suggest middle and index or middle and ring finger)(at once)
The early stage of vomiting causes metabolic alkalosis
Mostly X-ray diffraction patterns, basic knowledge of chemistry (neither were chemists), and simple guess work. There exists a bit of controversy over how much credit they (and others) should be given for this discovery.

It's been a lot of years since I worked in a lab, but if my memory serves me correctly, a pinch clamp is used on tubing to control the flow of a liquid through the tubing.j3h.

Chemists are trying to stop CFC use. these are the chemicals that destroy ozone.
They're used for removing clamps on washing machine hoses.

I think you are mistaken, a chemist (that is a chemists shop or pharmacy) will use its landlines (telephone) during the day to speak to customers.
Chemists use various kinds of technology. They use spectrometers to measure color changes. They also use computer simulation programs to avoid dangerous reactions, and lasers for precise reactions.
The term PPM stands for "parts per million." Chemists use this notation to describe the concentrations of things that are diluted. To make it a percentage, 1 PPM is equal to 0.0001%.
