  • Publication number: 20100080733
    Abstract: A needle assembly has at least one guide member supported by a first body for sliding movement between an extended position and a retracted position. A second body is attached to the guide member. A biasing member biases the guide member to the extended position. A liquid handling needle is coupled to the first body so sliding movement of the guide member toward the retracted position retracts the second body relative to the liquid handling needle. The second body is adapted to contact a sealed receptacle. The biasing member urges the guide member toward said extended position during insertion and during said removal of the needle from the receptacle whereby the second body remains in contact with the sealed receptacle as the guide member moves from its extended position to its retracted position during said insertion and from its retracted position to its extended position during said removal.

  • Patent number: 7597852
    Abstract: Apparatus and methods for screening a library of materials. Materials are provided in a plurality of locations on a substrate. The locations include first regions that are sufficiently transparent to a first form of radiation to permit analysis of the portion of the sample material supported in the first region using a first analytical technique, and second regions that are sufficiently transparent to a second form of radiation to permit analysis of a portion of the sample supported in the second region using a second analytical technique, but are insufficiently transparent to the first form of radiation to permit analysis of the portion of the sample material supported in the second region using the first analytical technique. Sample materials are screened at one or more sample locations of the substrate using the first analytical technique in the first region and the second analytical technique in the second region.

  • Patent number: 7549978
    Abstract: A needle assembly has a first body and a guide rod supported for sliding movement between an extended position and a retracted position. A second body is attached to the guide rod. The second body is relatively farther from the first body when the guide rod is in the extended position and relatively closer to the first body when the guide rod is in the retracted position. The guide rod is biased to the extended position. The second body supports a venting needle that extends beyond the second body by a fixed length. A liquid handling needle is coupled to the first body. Sliding movement of the guide rod toward the retracted position retracts the second body and the venting needle relative to the liquid handling needle.

  • Patent number: 6939515
    Abstract: The invention provides methods, apparatus, and systems for performing high-throughput preparation and screening of salts and polymorphs of drug candidates. The invention is directed towards enhancing the pre-formulation discovery process used for drug development. In particular, processes that determine suitable salts and processes that discover substantially every polymorph that can form from a particular drug candidate are provided. The processes are performed using several apparatuses that are specifically configured to carry-out various steps in a high-throughput characterization process. One such apparatus is configured for synthesizing a plurality of library members based on, for example, a library model generated by a computer system. Another apparatus may filter the synthesized solution to provide a substantially pure mixture that can be subjected to salt or polymorph testing.

  • Publication number: 20040219602
    Abstract: The present invention relates to the field of research for drug formulations. More particularly, this invention is directed toward an apparatus and method of performing parallel synthesis and screening of multiple drug compositions for stability and compatibility when exposed to various conditions over time, including various environmental and/or chemical conditions. In one aspect, the invention includes a method of testing for effects of a condition on a drug sample. The method includes providing an array of drug samples, simultaneously exposing a first plurality of the drug samples in the array to a first controlled condition for a period of time within an exposure period, and evaluating a plurality of the exposed drug samples at a first time and a second time using a non-destructive test in order to determine whether the condition has an affect on one or more of the drug samples over time.

  • Patent number: 6792563
    Abstract: An electronic component for failure detection and analysis of bus activity comprises configuration circuitry, a buffer, and read circuitry. The configuration circuitry, the buffer, the read circuitry and the bus being tracked are on the same die. The configuration circuitry identifies one or more modes, one or more triggers, and one or more responses associated with the triggers. The buffer stores transactions on a bus according to the configuration circuitry. The read circuitry reads data from the buffer. A method of tracking bus activity comprises configuring a bus activity tracking component; monitoring an interface for a trigger event; and performing associated responses upon the occurrence of the trigger event.

  • Patent number: 6667009
    Abstract: Methods and devices for rapidly analyzing groups of reactions are disclosed. The method includes the steps of contacting a fluid sample from one of the reaction mixtures with a sorbent, trapping at least one component of the fluid sample on the sorbent, and detecting the at least one component of the fluid sample trapped on the sorbent. The contacting step, the trapping step, and the detecting step are carried out at least once for each of the reaction mixtures in rapid serial or parallel fashion. The present invention is useful for screening combinatorial libraries, especially libraries of catalysts made through parallel synthesis, but the disclosed methods and devices can be used to analyze a broad spectrum of chemical transformations.
