Abstract:
Disclosed herein are systems and methods for the developing of immuno-stained biological samples. The systems disclosed herein are automated and are configured to control one or more steps of the developing procedure. Reagents may be added using automatic syringe dispensing. Reagent temperature, reagent stirring, and wash procedures are programmable and can be separately controlled for separate immuno-staining procedures that are performed at the same time.
Abstract:
Disclosed herein is a modular test tube rack. The rack contains multiple sub-racks that can be coupled together to form the test tube rack. The sub-rack can be designed to fit into a variety of scientific instrumentation including a fixed rotor centrifuge. The assembled test tube rack can be of a format and size that allows use of standard array pipetters. Thus, a system is provided allowing use of standard array pipetters and high g centrifugation.

Abstract:
A device for characterizing the biological properties of cells can include a plurality of dual-compartment assay chambers wherein the compartments of each chamber are separated by a cell layer across which ions can flow. The biological properties of the cell layer in the presence or absence of experimental compounds can be determined by measuring an electrical gradient across the layer. A individual dual-compartment chamber of this type may be referred to as an “Ussing chamber.”
Abstract:
An air displacement pipetter comprises a guidance sleeve positioned within a hole in a cylinder block and a piston within a portion of the guidance sleeve a piston penetrating the cylinder block, a spring energized seal disposed within the cylinder block, a seal capture plate contacting the spring energized seal, a carrier plate, a pipette tip attached to the carrier plate, and a manifold plate between said carrier plate and said cylinder block.
Abstract:
An apparatus for high-throughput screening and generation of chemical libraries. The apparatus comprises computer controlled mechanical displacement devices and storage queues capable of managing a large number of source well plates and target well plates. In one aspect of the invention, precession alignment mechanisms are provided for efficient transfer of liquid from source well plates to target well plates. The apparatus may be configured such that any source fluid in any of the source well plates may be transferred to any target location within any of the target well plates in any sequence defined by the user. The computer controller may track the location of all the source well plates and target well plates and allow user defined association of any source well with any target well in any order defined by the user, thus providing an effective platform for chemical and biochemical synthesis and screening.
