spatulas are used to transfer
samples or chemicals from their original containers to weighing paper, weighing boats, weighing bottles, weighing funnels, or other vessels or containers for weighing
19
A wash bottle is a squeeze bottle with a nozzle, used to rinse various
pieces of laboratory glassware, such as test tubes and round bottom flasks, and to add distill water into a container or to clean an insoluble product.

Test tube racks are laboratory equipment used to hold upright multiple test tubes at the same time. They are most commonly used when various different
solutions are needed to work with simultaneously, for safety reasons, for safe storage of test tubes, and to ease the transport of multiple tubes. Test tube racks also ease the organization of test tubes and provide support for the test tubes being worked with.

It is used to make up a solution to a known volume. Volumetric flasks are used to measure volumes much more precisely than beakers or Erlenmeyer flasks.
Filtering flasks are used in numerous general laboratory procedures for rapid filtration of liquids.

The use of mortar and pestle is to grind, mesh or crush various
ingredients. One of the key applications and use of mortar and pestle is to transform
ingredients into fine powder and paste.
NATURAL RUBBER PIPETTE FILLER
Rubber bulbs are pieces of lab equipment used to create suction in pipettes or
burettes in order to fill said glassware with a solution of a liquid reagent.
31. PESCA IMANTS- MAGNETIC RETREIVER
A very strong magnet
placed inside the head of the hammer can be used as a tool for looking for lost magnetic items or for retrieving those objects from less accessible
places.
to remove a stir bar from all glass and plastic containers
32.PINCES-TWEEZERS
A small piece of equipment made of two narrow strips of metal joined at one end. It is used to pick up small objects by pressing the two strips of metal together with the
fingers.
FORCEPS
33.CLAMP/PINÇA(ABRAÇADERA)
It is used to hold round
laboratory glassware, such as a beaker, and flasks, etc. This type of clamp is made from stainless steel.
34.PINCES DE BURETA- BURETTE CLAMP
A burette clamp is an
essential tool for any lab that requires heating a
solution with a burner and ring stand. This metal tool attaches to the stand to hold a glass burette, test tube, flask, etc.
Burette clamp is a
scientific equipment which used specifically to hold and secure a burette on a stand, so that a burette is fixed and more convenient for the experiment. ...
Usually burette clamps come in doubles, which means they can hold two burettes

Laboratory tongs are large pincers for grasping and lifting vessels of heat-resistant material used in high temperature chemical reactions.
39. Pipeta aforada
Volumetric Pipette: allows extremely accurate measurement of the volume of a solution.
are designed to very accurately transfer a specific amount of solution.
40. Pipeta d’un sol ús
Disposable pipette
disposable plastic pipets used to transfer small volumes of liquids.
A refrigerant tube or condenser is a laboratory apparatus, made of glass, that is used to condense the vapors that come off the distillation flask, by means of a refrigerant liquid that circulates through it, usually water.

Wire gauze is an important piece of supporting
equipment in a laboratory as glassware cannot be heated directly with the flame of a Bunsen burner, and requires the use of a wire gauze to diffuse the heat, helping to protect the glassware.
The main purpose of a rubber stopper is to prevent a gas or liquid from escaping from its container during a science experiment. The rubber stopper can be used to seal a bottle
because the user wants to mix the content, or to store it and prevent loss and contamination.
PLASTIC CAPS Tap de plàstic
49. STOPPER
A metal structure for holding glass tubes and other equipment during scientific test and experiments
While a lab thermometer can measure how hot or cold a sample or
environment is, the range of
measurement can vary widely between models.

Rubber tubing is used in flow lines for fluids and gases between lab
glasswares and lab porcelains. Base burette, glass condenser and many other experimental apparatus need rubber tubing.

Goggles or safety glasses are forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates water or chemicals from striking the eyes. They are used in
chemistry laboratories and in woodworking. Working in a lab where you dont want chemicals splashing in your eyes.
56. vareta d’agitació
A glass stirring rod is used to stir or mix solutions.
One of their main uses is to “scratch” the side of
glassware (such as an Erlenmeyer Flask) to start the crystallization process in many experiments.
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.
57.BEAKER/ VAS PRECIPITATS
A beaker is a cylindrical glass or plastic vessel used for holding liquids. It is a multi- purpose piece of
equipment used for containing a chemical reaction, measuring liquids, heating them over a Bunsen
burner's flame or collecting them in a titration experiment.
58.VIAL AND SCREW CAP/VIA AMB TAPA DE ROSCA
Screw caps deliver leak-proof seal for all types of contents, ideal for life science
reagent or solution. All vials are available in skirted and conical interiors to allow full recovery of samples stored.
Vials are small bottles or containers made from either plastic or glass.
They’re used to store medicines in liquid form, and they can even store powders or tablets.
A watch glass is a
circular concave piece of glass used in
