Multiple chemical reactions are performed in a plurality of reaction vessels (12) mounted in inlets in a manifold valve block (30). The manifold valve block (30) is connected to a channel block (34) which is utilized in conjunction with a solvent delivery system (21) as part of the reaction cycle. The solvent fluid is drained from the reaction vessels (12) when valves in the manifold valve block (30) are opened while applying a vacuum thereto. Optionally, a thermal block (40) may be utilized in conjunction with the manifold valve block (30) and the channel block (34) to facilitate the reaction. Upon completion of the reactant cycle, the manifold valve block (30) is disconnected from the channel block (34) and connected to a cleavage block assembly (120, 121) which contains vials (128) for collecting reaction products. The cleavage product is drained from the reaction vessels (12) through the manifold valve block (30) into the vials (128) upon opening the valves in the manifold valve block (30) and applying a vacuum to the channel block (34).
On peut procéder à des réactions chimiques multiples dans une pluralité de réaction (12) placés dans les entrées d'un bloc (30) de valves collectrices. Ledit bloc (30) est relié à un bloc (34) de canaux associé à un système (21) de distribution de solvant utilisé pour le cycle de réaction. Le solvant fluide est extrait des récipients de réaction (12) lorsque les valves du bloc (30) s'ouvrent sous l'effet d'une dépression. On peut facultativement utiliser un bloc thermique (40) associé au bloc (30) de valves collectrices et au bloc (34) de canaux pour favoriser la réaction. A l'issue du cycle de réaction, le bloc (30) de valves collectrices est déconnecté du bloc (34) de canaux et connecté à un ensemble de blocs (120, 121) de clivage pourvu de flacons (128) recueillant les produits de réaction. Le produit de clivage sort des récipients de réaction (12) par le bloc (30) de valves collectrices et passe dans les flacons (128) lorsque les valves du bloc (30) de valves collectrices s'ouvrent et qu'on soumet le bloc (34) de canaux à une dépression.
