Legal Notice

The "Digital Lab Techniques Manual" is a series of videos designed to help you prepare for your chemistry laboratory class. Each video provides a detailed demonstration of a common laboratory technique, as well as helpful tips and information. These videos are meant to supplement, and not replace, your lab manual and assigned reading. In fact, you will most benefit from watching the videos if you have already read the appropriate background information. To be a great experimentalist, you must understand both theory and technique! If you have questions about what you see, make sure to ask your TA or your instructor. The full "Digital Lab Techniques Manual" is available in our Supplemental Resources section under Chemistry.

These files are also available on iTunes® and YouTube™.

Note: In 5.301, videos 3, 5, 6, 9, and 10 are used.

VIDEO #DESCRIPTIONFILES
3TLC-The Basics
Thin-layer chromatography is the most commonly used analytical technique in many research labs. This video walks you through every step, from setting up a developing chamber to calculating Rf values.
(RM - 56K) (RM - 80K) (RM - 220K)
5Reaction Work-Up I
Extracting, Washing and Drying: It ain’t over ‘til it’s over. Learn how to "work up" your reaction using a separatory funnel to perform a liquid-liquid extraction. This is one purification technique you don’t want to miss!
(RM - 56K) (RM - 80K) (RM - 220K)
6Reaction Work-Up II
Using the Rotavap: The rotary evaporator is your friend in the lab. This video will ensure that you build a safe and productive relationship.
(RM - 56K) (RM - 80K) (RM - 220K)
9Recrystallization
Recrystallization takes patience, but it’s worth it! This video walks you through the procedure, from solubility tests to cold filtration, with information on one-solvent and two-solvent recrystallizations.
(RM - 56K) (RM - 80K) (RM - 220K)
10Column Chromatography
It takes considerable practice to master the art of "running a column". This video will get you started, with tips on picking appropriate conditions, packing and running a column, monitoring separation, and even making a micro-column from a pipet.
