The present invention relates to cost effective analytical instruments for determining the presence or amount of an analyte in a sample. The analytical instruments utilize an assay cartridge which has a sample receiving port and a rotatable carousel containing a plurality of reagent wells. Each reagent well includes a piston element for delivery of reagent to a test surface. The instrument is capable of indexing the assay cartridge to deliver sample and reagents to a test surface in a predetermined and flexibile manner, thus providing an assay protocol which is specific to the type of sample under analysis. The invention also relates to components, features, disposables, reagent delivery systems, accessories, and methods for using such instruments. Appropriate applications include infectious disease testing, cancer detection and monitoring, therapeutic drug level monitoring, allergy testing, environmental testing, food testing, diagnostic testing of human and veterinary samples, and off-line process testing.

The present invention relates to a instrument for use in an air abrasion dental instrument that allows direct contact between a nozzle which delivers a stream of abrasive particles directly through a primary opening to a tooth surface. As the primary opening if the nozzles of this invention are in continuous close contact with a tooth surface, exhaust amounts of abrasive-laden fluid escape secondary openings at a direction lateral to the tooth surface. The invention also embodies removable nozzle covers having both primary and secondary openings that enable prior art nozzles to be easily converted to contact nozzles. Both the nozzles and removable nozzle covers of this invention define areas for dental restoration that remove a minimal amount of healthy tooth structure. The invention allows the comfort of air abrasion dentistry to the patient as well as both visual and tactile feedback to the dentist, the latter filling a long felt need of the practicing dental community.
