After your CentriVap has been installed as detailed in Chapter 3: Getting Started,
you are ready to begin using your CentriVap. Read this chapter to learn how to:
• Set operating parameters.
• Operate the controls.
• Properly select and position glassware inside your CentriVap.
• Understand the display.
• Interrupt a cycle after it has begun.
Note: See Appendix C: CentriVap Specifications for electrical requirements.
Note: Do not store or stack supplies or equipment on top of the CentriVap.
Planning
Thoroughly understand procedures and the equipment operation prior to
beginning work. The unique performance of the CentriVap is dependent upon the
proper balance of heat, vacuum and centrifugal force. If the proper balance is not
established, it is possible to damage or lose a portion of the sample. Therefore, if
you are unfamiliar with the CentriVap or are attempting a new protocol, it may be
helpful to make a trial run that is void of the sample you are attempting to
concentrate.
Glassware Selection
Normally, sample tubes should be filled no more than approximately half full.
Select the size of the sample tube so it is compatible with the rotor and the desired
sample size. Tubes should not be loose in the rotor. Rotors are available with
holes for various size tubes. Refer to Chapter 6: Accessories for Your CentriVap
for available rotor sizes.
