SEPARATING AND MIXING
 B01
PHYSICAL AND CHEMICAL PROCESSES AND APPARATUS (IN GENERAL) (furnaces, kilns, ovens, retorts, in general F27)
 B01B
BOILING; BOILING APPARATUS

 B01D
SEPARATION (separating solids from solids by wet methods B03B, B03D; by pneumatic jigs or tables B03B; by other dry methods B07; magnetic or electrostatic separation B03C; centrifuges, vortex apparatus B04)
 B01D

Note(s)

  1. The processes covered by this sub-class include evaporation, distillation, crystallisation, filtration, dust precipitation, gas cleaning, absorption, adsorption.
  2. This sub-class also includes similar processes which are not concerned with, or limited to, separation (except in the case of absorption or adsorption).
  3. The word "filtration" and related words should be interpreted as embracing straining liquids from solids.
  4. For apparatus used in drying or evaporation, F26 takes precedence over B01D.

    The following note is of interest in considering the sub-divisions of this sub-class:

    Group B01D 59/00 takes precedence over the other groups of this sub-class and over other sub-classes.

 B01F
MIXING, e.g. DISSOLVING, EMULSIFYING, DISPERSING

 B01J
CHEMICAL AND/OR PHYSICAL PROCESSES, E. G. CATALYSIS, COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS

 B01K
ELECTROCHEMICAL PROCESSES AND APPARATUS; ELECTROPHORESIS (isotope separation B01D 59/38; electrolytic and electrothermic production and refining of metals C22D)

 B01L
CHEMICAL OR PHYSICAL LABORATORY APPARATUS FOR GENERAL USE (apparatus for medical and pharmaceutical purposes A61; apparatus for industrial purposes and laboratory apparatus whose construction and performance are comparable to that of similar industrial apparatus, see the relevant classes for industrial apparatus, particularly sub-classes of B01 and C12; separating or distilling apparatus B01D; mixing or stirring devices B01F; atomisers B05B; vibrating devices. e.g. shaking tables B06B; sieves B07B; corks, bungs B65D; handling liquids in general B67; vacuum pumps F04; siphons F04F 10/00; taps, stop-cocks F16K; tubes, tube joints F16L; apparatus specially adapted for investigating and analysing materials G01, particularly G01N; electrical or optical apparatus, see appropriate classes in Sections G and H)
 B01L

Note(s)

This sub-class is intended to take only laboratory apparatus which is either applicable solely to laboratory purposes or which, by reason of its simple construction and adaptability, is such as would not be suitable for industrial use.
