1. Dear Drugs-Forum readers: We are a small non-profit that runs one of the most read drug information & addiction help websites in the world. We serve over 4 million readers per month, and have costs like all popular websites: servers, hosting, licenses and software. To protect our independence we do not run ads. We take no government funds. We run on donations which average $25. If everyone reading this would donate $5 then this fund raiser would be done in an hour. If Drugs-Forum is useful to you, take one minute to keep it online another year by donating whatever you can today. Donations are currently not sufficient to pay our bills and keep the site up. Your help is most welcome. Thank you.

    Vacuum distillation is one of the fundamental techniques for advanced organic chemistry. When more than one fraction has to be collected from a vacuum distillation, it becomes necessary to use either a fraction cutter or a cow receiver. However, the high cost of a fraction cutter (usually in the range of US$400-500) severely limits its use in undergraduate laboratory teaching. On the other hand, a cow receiver, which is cheaper, can accommodate only three to four fractions and is quite troublesome to set up. We describe here a homemade fraction cutter which can he easily assembled with standard laboratory glassware as shown in the figure.
