Lab Equipment for Chemistry
Chemistry 1 & AP Chemistry Laura Peck Dickson County High School Dickson, TN ●Micro well plate – small scale reactions.
●Beaker – full scale reactions. Accurate to 10ml for large beakers and 1ml for the smallest beakers ●Pipette – small liquid sample, accurate to .1-.01ml (depending on type of pipette)
●Graduated cylinder – measure liquid. Accurate to . 1ml (depending on skill of lab partner) ●Burette – gravity fed measuring apparatus. Solution is poured in from the top and measured as it drains into flask or beaker.
●- Must be secured to a ring stand using clamps. ● - Is read ‘backwards’. You fill it to 0ml at the top and it drains towards 50ml. ● - You control flow speed by turning the knob at the bottom. Horizontal is ‘off’ and Vertical is ‘fully open’ ● - this is the most accurate measuring device for solutions. ● - For clear solutions, hold a colored card behind for easier reading of meniscus ●Erlenmeyer Flask – heat reactions on hot plate
●Round-bottom flask – heat reactions over flame ●Test tube – small scale reactions.
●Test tube rack – holds test tubes. ●Spatula – scoop solid samples.
●Alcohol burner – heat
●Hot Plate - heat ●Ring Stand – hold test tubes/ flasks over flame
●Stand – hold beakers over flame
●Tongs – Used to pick up hot containers
●Watch glass – hold small amounts of products ●Micro Digital Scale
●Digital Scale
●Triple Beam Balance ●Filter Paper – transport solid samples
●Goggles – Eye protection ●Crucible w/Lid - heat small samples to dry or dehydrate
●Crucible holder triangle - cradles crucible securely over flame.
●Mortar & Pestle - grinds solids into fine powder. ● Gas collecting apparatuses ● - (AP must know)
● Heavier than air gases Apparatus – example is the CO2 Collection Apparatus. No water trough.
● Lighter than air gases Apparatus - Example is the Hydrogen collection apparatus. Uses water trough. ●Buchner Funnel ●(AP must know) ●- used to filter out suspended particles in a solution. ●- Apparatus uses an Erlenmeyer flask w/side arm.
