GROUP 1 Flashcards
Holds small amounts of substances for mixing, heating, or observing reactions. To use, add the substance to the tube. use a test tube holder if heating, and heat gently by moving it in and out of the flame.
TEST TUBE
A clamp used to handle test tubes, especially when they are hot. to use, squeeze the handles to open the clamp, place it around the test tube, and release to secure it. Use the holder to safely handle or heat the test tube.
TEST TUBE HOLDER
A stand that keeps test tubes upright and organized. To use, place test tubes into the rack’s slots to keep them stable and prevent spills. Use the rack for organizing or transporting multiple test tubes.
TEST TUBE RACK
A glass container used for mixing, heating, and pouring liquids. to use, pour the liquid into the beaker, stir if needed, and heat gently on a hot plate or over a Bunsen burner. Use the beaker’s spout for controlled pouring.
BEAKER
A conical flask for mixing, heating, and storing liquids with minimal risk of spills. to use, pour the liquid into the flask, swirl gently to mix, and heat on a hot plate or Bunsen burner if required.
Cover with a stopper or lid when storing.
ERLENMEYER FLASK
A glass rod used to mix or stir liquids. to use, place the rod in the liquid and stir in a circular motion until the mixture is well combined.
Rinse the rod after use to avoid cross-contamination.
STIRRING ROD
A tool for measuring and transferring precise volumes of liquid. to use, squeeze the bulb or plunger to draw liquid into the pipette, then release to transfer the liquid to another container. Ensure accuracy by reading the measurement at eye level.
PIPETTE
Paper strips used to measure the acidity or alkalinity of a solution. to use, dip the strip into the liquid, wait for the color to change, and compare it to the provided pH scale to determine the pH level.
PH METER STRIPS
A paper strip used to measure the ph level of a solution. to use, dip the paper into the liquid, wait for the color to change, and compare the color to the provided pH scale to determine the acidity or alkalinity.
PH PAPER
A container filled with water used to heat substances at a controlled temperature. to use, place the container with the substance in the water bath, set the desired temperature, and heat gently. Ensure the water level is sufficient to cover the substance but not overflow.
WATER BATH
A mesh used to support glassware during heating and distribute heat evenly. To use, place the wire gauze on a ring stand or support, and then place the glassware fe.g., beaker or flask) on top of it before heating.
WIRE GAUZE
tools used to grind solids into powders. to use, place the substance in the mortar and use the pestle to grind and crush the material with a twisting motion until you achieve the desired consistency.
MORTAR AND PESTLE
A precise scale for measuring the mass of substances. to use, place the substance on the balance’s pan, close the cover, and read the mass displayed on the screen. Ensure the balance is calibrated and zeroed before measuring.
ANALYTICAL BALANCE
A tool used to pour liquids or powders into containers with narrow openings. to use, place it in the container, and pour the liquid or powder through the funnel to direct it into the container without spills.
FUNNEL
A shallow dish used to evaporate liquids and concentrate solutions. to use, pour the liquid into the dish and heat gently on a hot plate. the liquid will evaporate, leaving behind any dissolved solids.
