Cards in this deck (8)
- 1Microfuge tubescontain a small amount of substance | there is a cap to prevent spillage and evaporation of content
- 2Petri Dish | Culture DIshused to house mediums | culture medium provides nutrients to help growth of bacteria
- 3MicropipettesMeasure a small volume accurately
- 4Micropipette (part 2)comes in different models and volume range | dispenses liquids in microlitres
sizes:
p1000: 100-1000
p100: 10-100
p10; 0.5-10 - 5Autoclave Machineused high heat and pressure to sterilise equipment or culture medium before use | kill harmful organisms to prevent contamination and inaccurate results
- 6Laminar Flow Cabinetan enclosed bench that provides sterile air to the work space|air is drawn through a HEPA filter and blown in a very smooth, laminar flow towards the user| filters off dust particles, bacterial and fungal spores|the air blown from the HEPA filter is 99.9% pure air|has a UV-C germicidal lamp to sterilize the bench when not in use
- 7ultracentrifuge/microcentrifugeuses a high speed motor to separate mixture|the heavier molecules will be spun down and collected as a pellet|the clear liquid on top is the supernatant
- 8Vortexer/Vortex Mixerconsists of an electric motor cupped to a rubber piece|as the motor runs, the rubber piece oscillates rapidly|when a microfuge tube is pressed into the rubber cup or touches the edges, the motion is transmitted to the liquid inside and a vortex is created |for mixing substances|re-suspending pellets or cells|dissolving solids in a liquid
