DEFINITION

Classification: 422/50

ANALYZER, STRUCTURED INDICATOR, OR MANIPULATIVE LABORATORY DEVICE:

(under the class definition) Apparatus for quantitative or qualitative chemical analysis and laboratory devices.

SEE OR SEARCH CLASS

73, Measuring and Testing, for apparatus for making tests and measurement not otherwise provided for. See particularly

38, for testing illuminating fluids for flash point, vapor

pressure, and end point.

137, Fluid Handling,

88+, for systems for controlling the mixture of a plurality of fluids in response to the sensing of a condition or characteristic of the mixture, note particularly subclass 93 in which the control is in response to a sensing of a chemical property.

196, Mineral Oils: Apparatus, 132, and 141 for combinations of apparatus for making a test or measurement and means for controlling a reaction provided for in that class.

204, Chemistry: Electrical and Wave Energy,

400, 435 for apparatus specialized for the determination of a hydrogen ion concentration of solutions.

324, Electricity: Measuring and Testing, appropriate subclasses for apparatus for testing an electrical property or condition of a material by electrical means, even though the results of the test may be used as an indication of some other physical or chemical property or condition.

346, Recorders, for recording apparatus, per se.

374, Thermal Measuring and Testing,

8, for flammability testing; and subclasses 31+ for calorimetry.

436, Chemistry: Analytical and Immunological Testing,

1+, for similar processes.

588, Hazardous or Toxic Waste Destruction or Containment,

260, for the sensing, detecting, or monitoring of hazardous or toxic waste during storage or containment.
