pipette classification

• Pipettes are used to transfer liquids from one container to another.
• burets used to dispense a particular volume of liquid during a titration
• syringes used to transfer small volumes in blood gas analysis or in separation techniques such as chromatography or electrophoresis
• dessicant is to prevent moisture
• dessicator closed, airtight chamber used with dessicant.
• Class A pipets do not require recalibration
• Distilled water is the calibrating medium for TD pipettes
• Mercury is for the TC pippetes
• Gravimetric and pectometric methods used to verify pipette volume accuracy and precision
• 1 lambda = 1microliter (0.001mL)
• 1microliter = 1.0miligram
• Plastic pipet tips is made primarily of polypropylene
• Acid Dichromate is a cleaning solution for glassware
