Type of material

1.- Glass funnel

The funnel is an instrument used to channel liquids and granular solid materials into containers with narrow mouths. It is mainly used in kitchens, laboratories, construction activities, industry, etc.

It could be glass, plastic.

2.- Beaker

A beaker or beaker is a cylindrical container of fine glass that is very commonly used in the laboratory, especially to prepare or heat substances and transfer liquids.

Generally made of glass but there are also plastic and metal.

3.- volumetric flask

What is the volumetric flask for? It is a glass container that is used mainly to contain and measure liquids.

They are used in quantitative chemical analysis operations to prepare solutions of defined concentrations.

What material are volumetric flasks? Glass material.

4.-Reagent bottle

It allows: to save substances to store them, there are amber and transparent ones, amber ones are used to store substances that are altered by the action of sunlight, those of transparent color are used to store substances that are not affected by sunlight.

Glass or plastic material

5.- Spiral condenser

It is used to condense the vapors that emerge from the distillation flask, by means of a cooling liquid that circulates through it, usually water.

Of glass.

6.- Straight Condenser

The Refrigerant Tube or Condenser Tube is a glass device that allows the gases that are given off in the distillation process to be transformed into a liquid phase.It is made up of two concentric cylindrical tubes. The gas to be condensed will circulate through the inner tube of the tube and the refrigerant liquid will circulate through the outermost conduit.

Of glass.

7.-Millimeter specimen

The test tube is a volumetric instrument that consists of a graduated cylinder, that is, a scale is engraved on the outside that allows a certain volume to be measured.It is made up of a generally transparent tube a few centimeters in diameter and has a graduation from 5 ml to the maximum of the test tube, indicating different volumes. The lower part is closed and has a base that serves as support, while the upper part is open (allows the liquid to be measured) and usually has a spout (allows the measured liquid to be poured).

Of glass.

8.- Pipette

 

The pipette is a volumetric laboratory instrument made up of a transparent tube, usually made of glass, which ends in one of its conical tips, and has a graduation (a series of engraved marks) indicating different volumes.It is calibrated in convenient units to allow the transfer of any volume from 0.1 to 25 ml.

Of glass

9.-decantation pear

The separatory funnel is a glass container shaped like an inverted pear or an inverted cone.  This has a drain that allows the exit of the liquids that are to be separated in the lower zone of the container, whose flow can be controlled by means of the use of a valve. In the upper part it has an opening that can be sealed with a lid, which allows its interior to be filled with insoluble or immiscible liquids.

Of glass.

10.- Flat base ball

Flat-bottom flasks are round flasks, usually composed of a single neck, that are used to heat compounds in distillation or other reactions. They normally serve to contain liquids and subject them to high temperatures. 250ml, 500ml, 1000ml, 2000ml.

Of glass.

11.- Alcohol or rum lighter

Alcohol lighters consist of a round glass container with a flat bottom. In its upper part it has a cylindrical projection through which a metal tube of a few millimeters in diameter is screwed. Through this, a wick is inserted whose rear end is in contact with the alcohol contained in the container.

Made of glass or metal.

12.- Bunsen burner

The bunsen burner is an instrument used in laboratories to heat samples and chemicals  The bunsen burner is made up of a vertical tube that is screwed to a metal foot with an inlet for the gas flow, which is regulated through a key on the work table. In the lower part of the vertical tube there are holes and a movable metal ring or collar also drilled.

Of metal.

13.-Asbestos grid

It is responsible for distributing the temperature evenly, when heated with a lighter. A laboratory tripod is used for this, as it acts as a holder when experimenting.

Of metal.

14.-Combustion spoon

The combustion ladle is an instrument used in laboratories, especially in chemistry, to experiment with combustion reactions. These reactions are characterized by releasing heat, so additional safety methods must be employed in order to avoid burns.

Of metal.

15.-Clamps for test tube

Test tube clips are used to hold test tubes while they are being heated or handled. This allows, for example, the contents of the tube to be heated without holding the tube by hand.

Of metal.

16.- Test tube

It is a small glass tube with an opening in the upper area, and in the lower area it is closed and concave.

It is made of a special glass that resists very high temperatures, however very radical temperature changes can cause tube breakage (Pyrex).

In laboratories it is used to contain small liquid samples, and to prepare solutions.

Of glass.

17.- Flask

 

The laboratory flask is a container of cylindrical or conical shape, made of glass, crystal or plastic, finished in a narrow or long tube that mainly serves to contain a certain liquid without the risk that it can be poured.

Of glass.

18.-Watch glass

A laboratory instrument designed as a circular sheet of transparent glass is known as watch glass or watch glass. Its shape is concave-convex and its name comes from its resemblance to the glass that covered the face of ancient pocket watches.

Porcelain.

19.-Slides

Transparent colored rectangular glass sheet used to store samples and objects for viewing under the microscope. The typical dimensions of a slide are 75mm x 25mm, however they may vary depending on the type of object or sample (75 x 50mm slides are usually used in geology).

Of glass.

20.-Crucibles

The porcelain crucible is a laboratory material used primarily for heating, melting, burning, and calcining substances. Porcelain allows it to withstand high temperatures.

Porcelain.

21.-Porcelain capsule

The porcelain capsule is a small hemispherical container with a spout on its side. This is used to evaporate excess solvent in a sample  Porcelain Capsules exist in different sizes and shapes, covering capacities from 10 ml to 100 ml.

Porcelain.

22.-Mortar with pistil

The Mortar is intended to crush or grind solid substances.

The Mortar has a small instrument created from the same material called “Hand or Pilon” and is in charge of grinding.

They are usually made of Wood, Porcelain, Stone and Marble.

 

Made of porcelain or glass.

23.-Gradilla

A rack is a utensil used to support test tubes or sample tubes. It is normally used to hold and store tubes. This is made of wood, plastic, or metal.

Made of plastic, wood, metal.

24.-Caliper

Laboratory tweezers are a type of adjustable clamp, usually made of metal, that is part of the laboratory equipment, by means of which different glass objects (laboratory funnels, burettes …) can be supported or more elaborate assemblies can be carried out (distillation apparatus ). They are fastened by means of a double nut to a foot or laboratory support or, in the case of more complex assemblies (Schlenk line), to a fixed frame or grid.

Of metal.

25.-Swabs

Depending on the diameter, they are used after physics, chemistry or laboratory tests to wash: test tubes, burettes, beakers, erlenmeyer flasks, etc …

Of metal.

26.-Tripod

It is used when you do not have the universal holder to hold objects firmly. It is widely used in various experiments. The purpose it fulfills in the laboratory is only one, since its main use is as a support tool in order to avoid movement. A metal mesh is placed on the tripod platform so that the flame does not hit the glass directly and the heat is better diffused.

Of metal.

27.-distillation flask

The Distillation Balloon or Distillation Flask is an instrument made of glass (Generally Pyrex), which can withstand high temperatures. This is composed of a spherical base, a cylindrical neck and a lateral mouth that originates from the latter.

Of glass.

28.-Circular base ball

The bottomless flask, distillation flask or Florentine flask is part of the glassware. It is a bottle with a long neck and a spherical body. It is thus designed to achieve uniform heating of substances. It is made of glass or special plastic.Its rounded base also allows the contents to be shaken or stirred without spilling any substance out of the container as a precaution.
