Pipetting Practice—
Super Value Laboratory Kit
By: The Flinn Staff
Students often have a very difficult time loading samples into agarose gel wells. Improperly loading will adversely affect the experiment. It is strongly recommended that students practice pipetting techniques before experimenting with real, very expensive test materials. In this kit, the wells are constructed of a unique gel material that is not easily destroyed by micropipet tips. The tough polymer material can also be rinsed and reused many times. The well holes are slightly oversized so students will be successful with their first pipet transferring experience. The reusable quality makes them a real bargain!
Super Value Kit is complete for 10 student groups. All materials are reusable. Micropipets are available separately.
Electrophoresis Buffer—
Demonstration Kit
By: The Flinn Staff
Dramatically demonstrate the chemical activity at the anode and cath- ode of your electrophoresis apparatus. The color changes at the two ends of the electrophoresis tank will be very striking when no buffer is used. When you add buffer solution during the follow-up run, the color will not change! Students will quickly understand why a buffer solution is used in an electrophoresis apparatus. Enough materials are provided for seven demonstrations.
Concepts: pH, buffer system, electrophoresis.
Time Requried: 20 minutes
Materials Provided: Universal indicator, sodium chloride solution, electrophoresis buffer solution, hydrochloric acid solution, sodium hydroxide solution, Beral-type pipets.
Note: Requires electrophoresis apparatus and power supply.

     Electrophoresis
In Five Simple Steps
Electrophoresis is one of the most popu- lar and versatile analytical techniques in research and industry. Bring the topics and techniques of today’s biological research to your students!
After gel has solidified, remove the end caps and pull the combs straight up from the gel.
1
Place rubber gaskets/caps on ends of tray.
Submerse the gel in the buffer-filled chamber and deliver the samples into the wells.
Prepare the gel solution and cast the gel.
Attach the safety cover, connect the power source and run the electrophoresis.
