A schematic diagram of a completely assembled VSC-33 analyzer is presented in Figure 3. Specific pipette filling instructions, given below, are designed to facilitate the absorption of carbon dioxide, oxygen, and carbon monoxide in sequence.. - Page 12 8. Connect the burette and the absorption pipettes together using the 1 1/2 inch pieces of the supplied rubber tubing. Check to ensure that the absorption pipettes are securely attached to the support clamps and that the stopcock bodies are free of debris to form leak-free seals. APEX INSTRUMENTS, INC.
