They are also useful to catch filtrates. Iron Stand is used for holding pieces of glassware in place. Volumetric Flask is used to measure precise volumes or to Triple Beam Balance is used to measure the mass of an object make precise dilutions. that is placed on the pan. It is measured in grams (g). Wash bottles are used for dispensing small quantities of distilled water. Bunsen Burner is a source of heat. Glass Funnel is for funneling liquids from one container to another or for filtering when equipped with filter paper. Test Tube is used for holding small samples or for containing small - scale reactions. Watch Glass is used for holding small samples or for covering beakers or evaporating dishes. Test Tube Rack is used to hold upright multiple test tubes at the same time. Wire Gauze is used on a ring supports beakers to be heated by Bunsen burners Test tube holders are for holding test tubes when tubes should not be touched.

Rapacon Graduated Cylinders are for measurement of an amount of Crucible Tong is used to lift a hot crucible from a furnace or for liquid. The volume of liquid can be estimated to the nearest 0.1 other items which cannot be handled with bare hands. mL with practice. Crucible w/ Cover is a cup-shaped piece of laboratory equipment used to contain chemical compounds when heating them to very high temperatures. Pipettes are used to dispense small quantities of liquids. Test Tube Brush is used for cleaning test tubes and the interior surfaces of other tubes or cylinders with narrow openings, as well as internal threads and drilled holes. Aspirator is used to suck fluids such as water and wet chemicals out of a dry container like bottles, dishes, or teacups. Stirring Rod is used for mixing liquid substances or chemicals. Clay Triangles are placed on a ring attached to a ring stand as a support for a funnel, crucible, or evaporating dish. Tripod Stand is often used in combination with other lab equipment, such as Bunsen burners, hot plates, and wire gauze, to provide a stable platform for heating and mixing chemical substances. Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Spatula is used to transport and distribute dry chemical compounds. BSN 1E : BIOCHEM (LAB) All Rights Reserved. 2  BIOCHEM (LAB) BIOCHEMISTRY (LAB) 1st Term BSN 1E | A.Y. 2024 - 2025 | Neil Bert R. Rapacon Alcohol Lamp is used to produce an open flame. It can be LESSON 2 : made from brass, glass, stainless steel, or aluminum. DIFFERENT TYPES Bullet 1 ○ Bullet 2 Evaporating Dish is used to hold samples of solids and small volumes of liquids. Water Bath is made up of aluminum and it is used to incubate samples at a constant temperature over a long period of time. Mortar and Pestle are used to grind up solid chemicals into fine powder and crush solids into smaller pieces. Laboratory Thermometer is used to measure the boiling point or freezing point during the experiment. Hot Pot is used to perform chemical reactions, to heat samples, and for numerous other activities in the laboratory. BSN 1E : BIOCHEM (LAB) All Rights Reserved. 3
