Use laboratory electrodes with pH meters to intermittently test the pH of a solution. Electrodes feature glass or epoxy bodies and come in either combination or half-cell styles. Laboratory electrodes are further categorized according to fermentation, general purpose laboratory,Specialty, and ion-selective applications. Fermentation electrodes resemble Industrial electrodes because they can be used continuously for several days. Fermentation electrodes are rugged, can be hooked up to some pH controllers, and are either autoclavable or in-situ-sterilizable. Beckman Coulter offers Nitrate, Flouride, Ammonia Gas Sensing, Chloride, Ammonium Ion-selective electrodes. There are a multitude of electrodes for your specific application. Here is a table to assist you in selecting the correct electrode for the correct application. *Biological samples, proteins, and tris buffer Calomel (Hg/Hg2Cl2) or double-junction *Pharmaceuticals Calomel (Hg/Hg2Cl2) or double-junction *Drinking water Standard Ag/AgCl with single-junction *Waste water Double-junction *Solutions with heavy metals Double-junction *Soil samples Soil electrode or double-junction *Fruits, cheese, and meat Spear-tip, Ag/AgCl *Flat surfaces, paper, skin Flat-surface

What is the difference between a laboratory instrument and a laboratory apparatus? An apparatus is a set of materials or equipment designed for a particular use. Laboratory equipment refers to the various tools and equipment used by scientists working in a laboratory. These include tools such as Bunsen burners, and microscopes as well as specialty equipment such as a humidity test chambers, Electroporators Hot Plates and Stirrers. Another important type of laboratory equipment is Laboratory glassware and plasticware

Silicone is a polymer incorporating the element Silicon, Si. The general formula is [R2SiO]n where R is an organic group and n represents the repeating nature of a polymer. R can be methyl, ethyl, phenyl... The properties of a silicone compound depends on the crosslinking between polymer chains. Silicone fluids have no crosslinking. Examples of fluids are Dow Corning silicone fluids for high and low temperature baths. Crosslinked silicone can range from a gel, to rubber, to a hard plastic. An example of silicone rubber is silicone pump tubing for peristaltic pumps and silicone clear stoppers. An example of silicone plastic is Saint Gobain Tygon tubing. Silicon is mostly found in silicon dioxide, SiO2. Silicon makes up around 26% of the earth's crust. Silicon is found right under carbon in the periodic table which means it has some of the same properties as carbon. For example silicon has semiconductor properties and it has the ability to combine with carbon hydrogen and oxygen producing silicone compounds. Glass is made from silicates, SiO2 minerals containing other metals such as borosilicate glass. Remember, don't confuse silicone with silicon they are related but not the same.

Three are two definitions of a LABEXPERT that I know of; one is a person who works in a laboratory environment that is very knowledgeable in the their field of work. The other is a Brady LABEXPERT handheld laboratory labeling system. Anyone working in a laboratory environment could use a little help from both LABEXPERT's. The LABEXPERT that I want to focus on here is a handheld printer labeling system that will generate legible lables in a professional appearance for an assortment of lab sample containers. This printer already knows your labeling needs!It will also reduce the amount of time spent on labeling sample containers by hand. Because it is a personal size you can take it with you to different areas of your laboratory. Some of the best features of this printer include, an Auto-serialization feature, it can print 40 lables in less than 2 minutes, time and date stamping, built in bar coding, and Identilab software! This labeler will assist you in ensuring that your test tubes, vials, bottles and jars, even your laboratory notebooks all have a professional appearance!~Now get back to the things you really enjoy doing in the lab!

Cryogenics is the branch of physics that studies the phenomena that occur at very low temperatures. In physics, the production of low temperature systems; in biology, the use of such a system to preserve genetic material, especially in situations where the survival of a plant or animal species that would normally pass on that material in the course of reproduction is endangered. The main use of cryogenics is the fractional distillation of air to produce oxygen, nitrogen, and other gases. This process requires cooling the air to low temperatures to liquefy the gases in it. Natural gas, oxygen, nitrogen, and other gases are often liquefied for storage and transport because the liquid form occupy lesser space than the gaseous form. You might use a Nalge Nunc Dewar Flask or a Taylor Wharton Constant Temperature Refrigerator for the transport of your biological material. Cryogenic temperatures are also used in medicine to preserve certain biological substances, like bull semen (for breeding purposes), whole blood, and bone marrow. There are several uses of Liquefied Gases when dealing in the Cryogenics field. Liquefied gases are used as coolants in various industrial processes. Liquid nitrogen is used to freeze foods quickly. Liquid nitrogen in medicine, it is used to chill a needle like instrument called a cryoprobe. Cryoprobe is used by Doctors to freeze and destroy certain kinds of tissue, including warts, skin tumors, eye tumors etc.
