  1. Fun with Volume Measurement Ellyn Daugherty SM Biotech Career Pathway www.BiotechEd.com www.emcp.com/biotech Ellyn@BiotechEd.com www.sargentwelch.com/biotech • Text - Chapter 3 • Lab Manual - Chapter 3 • Student CD Tutorials • Course Planner

  2. Volume Measurement in Biotech 1 Chapter 3

  3. Start with Graduated Cylinders • On all instruments: • What is the total volume that can be measured? • What is the value of each type of graduation?

  4. Review: Metric Measurements and Conversions 1000 1000 • L mL µL 92 mL = _________ µL 357 µL = _________ mL 0.5 L = _________ mL 0.557 mL = _________ µL

  5. Measuring Small Volumes with Pipets • Start with 10-mL pipets • Show it can be read up or down • Show zero, then to tip • Explain “TD” • Demo green pump and drawing up and dispensing • Add 5.60 mL of red solution to tube #1 • Add 2.80 mL of red solution and 2.80 mL H20 to tube #2, cap, mix • Compare tubes with other techs • Use the spec (at 400 nm) to compare them

  6. Measuring Small Volumes with Pipets • Repeat with 5-mL pipets • Show it can be read up or down • Show zero, then to tip • Use green pump • Using 13x100 mm, add 3.60 mL of red solution to tube #3 • Add 1.80 mL of red solution and 1.80 mL H20 to tube #4, cap, mix • Compare tubes with other techs • Use the spec (at 400 nm) to compare them

  7. Measuring Small Volumes with Pipets • Repeat with 2-mL pipets • Show it can be read up or down • Show zero, then to tip • Use blue pump • Using 13x100 mm, add 1.90 mL of red solution and 1.90 mL H20 to tube #5, cap, mix • Using 13x100 mm, add 0.95 mL of red solution and 2.85 mL H20 to tube #5, cap, mix • Compare tubes with other techs • Use the spec (at 400 nm) to compare them

  8. Measuring Small Volumes with Pipets • Repeat with 1-mL pipets • Show it can be read up or down • Show zero, then to tip • Use blue pump • Using 13x100 mm, add 0.90 mL of red solution and 2.70 mL H20 to tube #5, cap, mix • Using 13x100 mm, add 0.45 mL of red solution and 3.35 mL H20 to tube #5, cap, mix • Compare tubes with other techs • Use the spec (at 400 nm) to compare them

  9. Measuring Very Small Volumes with Micropipets • Start with any of the micropipets • Show how to determine its size and range • Show how to hold it so display can be read. • Demonstrate how to read it • Demonstrate first and second stop • Demonstrate how to put a tip on and eject the tip. • Demonstrate how to take up and dispense a sample.

  10. Measuring Very Small Volumes with Micropipets • Using the P-100 and yellow tips • Each partner measures 75.2 µL of one dye into their own 1.7 mL tube. • Demonstrate how to compare tube • Demonstrate to check it by sucking it up

  11. Measuring Very Small Volumes with Micropipets • Using the P-10 and white tips • Each partner measures 9.85 µL of one dye into their own 1.7 mL tube. • Demonstrate how to compare tube • Demonstrate to check it by sucking it up

  12. Measuring Very Small Volumes with Micropipets • Using the P-1000 and blue tips • Each partner measures 333 µL of one dye into their own 1.7 mL tube. • Demonstrate how to compare tube • Demonstrate to check it by sucking it up
