- container 4 can be drained to separate solid phase- bound intermediates that are retained in the container by the filter substrate 16, from excess reagents, solvents and byproducts.
- the reaction container can also be drained to isolate the desired synthesized molecules from the retained solid phase support in a cleavage step.
- the barrel drain 34 can also be rotated to a second position wherein the outer surface of the body 38 of the barrel drain blocks passage of reagents or products from the container 4 by preventing fluid communication between upper and lower portions 28 and 30 of vertical bore 24.

- borosilicate materials in the construction of the container 4 also facilitates formation of the protruding elongate conduit 10 which extends from the bottom of the container, i.e., because borosilicate structures can be formed by glass drawing techniques that are routine in the art. Further, this process readily allows the addition of the integral filter substrate 16 in the container 4 during formation of the reaction container.
- the filter substrate can be comprised of any material capable of retaining common solid supports on which chemical syntheses .are conducted.
- the filter substrate material should also be chemically inert with respect to the reagents used in the chemical syntheses conducted in the reaction vessels, durable, reusable and generally nondeformable over multiple uses.
- the filter generally has a mesh size ranging from about 10 to about 50 ⁇ m, although much larger mesh sizes are equally suitable for use in vessels where "pins” or “crowns” are to be used as the solid support.
- filter substrate 16 is a glass frit having, for example, a 16 to 40 ⁇ m filter size.
- valve body 18 can be formed from any suitable chemically inert polymeric material that is also substantially rigid and nonexpanding.
- the valve body can be formed from a poly(chlorotrifluoroethylene) such as Kel-F® or the like.
- substantially rigid, nonexpanding materials in the construction of the valve body 18 allows for compression fitting of a compressible barrel drain 34 within the horizontal bore 26 of the valve body. More specifically, the material used in the construction of the barrel drain should have good frictional characteristics relative to the valve body material.
- a compressible barrel drain for use in a valve body comprised of a substantially rigid material, one is able to achieve a positive pressure- and liquid-tight seal between those components by compression fitting the compressible barrel drain 34 within the horizontal bore 24 of the rigid valve body 18.
- Selection of a barrel drain material that has good frictional characteristics relative to the valve body material enables rotation of the barrel drain within the valve body without compromising the sealing between those materials.

- the key bores depicted in Figure 1 are disposed on opposites sides of the drain bore in the barrel drain.
- the key bores allow actuation of the barrel drain between its first and second positions by a turning key that fits within the bores.
- Such key bores can be configured in any suitable geometry, such as oval, semi-circular, C-shaped or D-shaped to accommodate complementary-shaped turning keys.
- the actuation means 40 can comprise a single key bore shaped as described above, or a plurality of bores arranged on one or both sides of the drain bore.
- a linear array of modular valve bodies is generally indicated at 52.
- the array comprises a plurality of valve bodies 54 having barrel drains 56 disposed within horizontal bores 58 extending through the valve bodies 54.
- the barrel drains contain drain bores 60 which allow communication between upper and lower portions of vertical bores 62 which extend through the valve bodies 54.
- the barrel drains also contain first and second key bores, respectively indicated at 64 and 66, which cooperate with a turning key 68 capable of simultaneously actuating the barrel drains 56 in each of the valve bodies 54 disposed in the linear array 52.
- the turning key 68 is formed from a suitable material that exhibits little or substantially negligible twist such that the turning key can simultaneously actuate each of the barrel drains 56 to accurately align the drain bores 60 with the upper and lower portions of the vertical bores 62.
- the turning key 68 can be formed from two tungsten/carbide rods which extend through the key bores 64 and 66. Tungsten/carbide materials are selected herein due to the high modulus of elasticity of such composite materials; however, any other material having a high modulus of elasticity can be substituted therefor in the construction of the turning keys.
- another component interface in the modular reaction vessel 2 comprises the mating surface between the elongate conduit 10 and the valve seat 32 in the valve body 18.
- this interface provides a sealing surface that needs to be both liquid- and pressure-tight in order to facilitate use of such reaction vessels in common solid phase synthesis processes.
- the valve body is comprised of a substantially rigid polymer such as poly(chlorotrifluoroethylene)
- the container 4 can be formed from a substantially rigid borosilicate and configured such that the external diameter of the elongate conduit 10 and the internal diameter of the valve seat 32 provide for a tight compression-fit between the elongate conduit and the valve body.
- a biasing means such as a spring clip or other tensioning device, can be used to maintain the conduit firmly in place within the valve seat 32 to provide a liquid-tight and/or pressure-tight seal.

- the barrel drain can be switched between a first position in which a drain bore 222 extending through the barrel drain is aligned with the vertical bore 216 extending through the valve body 214 thereby allowing communication of contents from the container 204 through the valve body, and a second position which prevents communication through the valve body as also described hereinabove.
- the array 202 of modular reaction vessels is maintained in linear spaced apart relation to each other within a rack 224 having a plurality of receptacles 226 configured to retain the array of reaction vessels.
- An actuation means 228 is provided which enables simultaneous actuation of the barrel drains 220 (e.g., between their respective first and second positions) in each reaction vessel arranged in the linear array 202.
- a number of like arrays can be retained within the rack 224, wherein the barrel drains in each of the vessels present in discrete linear arrays can be simultaneously actuated by an individual actuation means.
- a matrix can be formed by a plurality of linear arrays of two or more such modular reaction vessels. Chemical synthesis steps can be conducted in parallel in each discrete linear array.
- the rack 224 also contains openings 230 which accommodate the insertion of actuation means 228 for each linear array.
- the openings 230 also allow metallic or semi-metallic actuation means to be readily removed from the arrays, such as where it is desired to insert the rack 224 and reaction vessels into a microwave for a quick temperature adjustment. After heating, the actuation means can be easily reinserted.
- the present invention thus provides a method for carrying out parallel reaction steps in the solid phase chemical synthesis of a plurality of compounds, said method comprising:
- each vessel contains a substrate bearing a solid phase on which the reaction steps are carried out and (b) has associated with it a valving means configured to yield a first position allowing drainage of the vessel and a second position preventing drainage of the vessel;
- linear arrays of reaction vessels can be comprised of any number of individual containers, and matrices formed from such linear arrays can be comprised of any number of discrete linear arrays.
- the spacing between vessels in each linear array, and between linear arrays of vessels in a matrix can be adjusted to accommodate the use of various liquid handling devices such as multi-channel pipettors, aspirators and the like which can have a wide degree of variation in the spacing of individual liquid channeling means.
- the vessels can be arranged relative to each other in such a way as to facilitate the placement or removal of screw-cap closures for the containers, where it is convenient to have adequate finger space between vessels in order to manipulate individual caps.
- the vessel array depicted in Figure 4 is designed for ready use with associated devices, such as vacuum manifolds which facilitate the simultaneous draining of reagents from linear arrays of vessels, collection racks which can be used to retain filtrates from the vessels and temperature control devices which can be used to provide various reaction conditions for chemical syntheses conducted within the reaction vessels.
- associated devices such as vacuum manifolds which facilitate the simultaneous draining of reagents from linear arrays of vessels, collection racks which can be used to retain filtrates from the vessels and temperature control devices which can be used to provide various reaction conditions for chemical syntheses conducted within the reaction vessels.
- a rack 252 which contains a plurality of linear arrays of reaction vessels 254, wherein all of the barrel drains in each linear array are individually actuated by an actuation means 256 coupled to that array.
- the rack 252, containing one or more linear arrays of reaction vessels, can be placed upon an associated vacuum manifold 258, having means 260 for connecting the manifold with a vacuum source.
- the rack 252 can be placed in vacuum-tight relation with the vacuum manifold 258 which is then evacuated to provide a vacuum under the reaction vessels contained within the rack.
- the barrel drains in each of the reaction vessels can be opened, thereby allowing communication of excess reagents, solvents, byproducts from the reaction vessels to drain into the vacuum manifold for collection by an associated waste receptacle during washing steps.
- a gasket 262 such as a closed-cell foam comprised of a polyethylene, can be placed between the rack 252 and the lid 264 of the vacuum manifold 258 to improve the vacuum-tight seal between those components.
- a collection rack 266, containing a plurality of collection vials that correspond to each reaction vessel 254 included in the rack 252, can be inserted into the vacuum manifold 258 prior to placing the rack 252 into operative position with the vacuum manifold. In this manner, the filtrates from each reaction vessel can be individually collected and retained by the collection vials.
- a temperature control element 270 configured to fit over the top of each reaction vessel 254 in the rack 252, can be applied to regulate or adjust the temperature in the reaction vials.
- the temperature control element 270 is comprised of an aluminum block having heating elements attached thereto which can be placed over the reaction vials 254 to incubate the vessels at elevated temperatures.
