The TurboVap II sensor is designed to monitor the concentration process. It does this with light and logic. The sample tube stem sits in a light beam at about 0.8mL for 1mL tubes and at 0.5mL for the 0.5mL tubes. Every second, a microprocessor receives an indication of the change in optical density of the solution being concentrated. Small changes in optical density over a thirty second period are registered to memory and become the new initial or zero point for the sensor to look at the next change. When the sample is done and the meniscus crosses the sensor beam, a large change in optical density takes place and the TurboVap II beeps. The change for either dark or clear must persist for several seconds for the sensor to beep. At this point the gas flow stops and an alarm sounds to indicate that the sample is complete. When the attendant looks at the control panel, a blinking light indicates which position is complete.

User Report: V-10, Sumitomo Dainippon Pharma. Sumitomo Dainippon Pharma is recognized worldwide for its highly creative drug discovery program for treating neuropsychiatric disorders, and in specialized areas with high unmet medical needs. Its Genomic Science Laboratories installed the V-10 evaporation system in 2008, which has been used extensively for drying in-house compounds. We asked two researchers at that facility, Mr. Masahiko Ikeda and Mr. Fumitaka Nishino, about their use of the V-10 in their daily work.

This Chemistry Data Sheet describes the use of ISOLUTE® HM-N as a support material for pre-absorption of a
reaction mixture prior to flash chromatography. This approach is used as a solution to loading reaction
mixtures that are only soluble in polar solvents onto an ISOLUTE Flash SI II or Flash NH2 column.

In order to obtain a fast synthesis of an N-unprotected tripeptide, microwave (mw) assisted deprotection, coupling and partial deprotection were applied starting with a purified protected dipeptide [Fig. 1]. The three consecutive mw assisted steps were performed without any intermediate purifications and were accomplished within some 30 minutes. The resulting crude mixture containing the Boc deprotected tripeptide ester was shown to be quite complex [Fig. 2]. The crude product was subjected to automated reversed phase flash chromatography, followed by automated fraction pooling and “thin film evaporation”. The total time for the entire procedure was 1 h 20 min. The purity of the product was > 99%.
