DEFINITION

Classification: 435/287.1

Including measuring or testing:

(under subclass 283.1) Apparatus with means to test or measure a condition or property in a sample.

(1) Note. This subclass excludes mere means for measuring temperature or pH in combination with bioreactor structures. See this class, subclasses 289.1+ for this subject matter.

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.

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,

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 result 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,

31+, for calorimetry.

422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing, particularly
