摘要:
A method for rapidly and uniformly mixing solutions within a biochemical analyzer by rapidly and repeatedly moving a sampling probe in generally lemniscate shaped pattern within the solution is provided.
摘要:
A method and apparatus for adjusting the height of a tip of a mixing element, such as a needle probe, compares the mixing efficiency observed at two heights separated by a predetermined distance. The heights can be incrementally adjusted to determine the location of the bottom of a mixing vessel and, by extension, the approximate location for placing the mixing element for efficient mixing of solutions in the mixing vessel.

摘要:
Cleaning a liquid sample probe with a cleansing station having sources of air, cleansing solution, bath and shower water in a two-well cleansing body. The cleansing body comprises a multifunctional plate having features to provide both a wall of shower water and thin sheets of high velocity air that provide thorough cleaning of the sample probe
摘要:
Performing antibiotic testing on samples contained in test arrays by orienting the arrays relative to the direction of gravity so that test solution within the microwells is drawn downwards and air within the microwells is forced to the uppermost portion of the test array. Antibiotic testing is conducted using an interrogating beam of radiation passing horizontally through the microwells at locations devoid of air bubbles.

Analyzing the pressure profile generated during a predetermined period of time prior to the end of an aspiration or dispensing process and comparing a pressure reading to predetermined values to determine if the aspiration or dispensing pipette was free of clogs.

A method for rapidly and uniformly mixing solutions within a biochemical analyzer by rapidly and repeatedly moving a sampling probe in a two-dimensional boomerang-curved pattern within the solution.
摘要:
A sampling aliquotter for aspirating aliquot portions of sample fluid from a closed container and for dispensing aliquot portions into a vessel using horizontal and vertical drives to drive a probe into the closed container, to position the probe above the vessel, and to lower the probe into a cleansing module.
摘要:
A microbiological test array with a plurality of microwells connected by a microchannel to a solution reservoir. Subsequent to filling the microwells, the microchannels are sealed to protect the integrity of the solution in the test microwells.
