Chapter 4: Using Your 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
Appendix D: CentriVap Accessories
for
available rotor sizes.
Loading Glassware Into the
CentriVap
Smooth operation of the CentriVap is dependent upon
proper balance of the machine. Therefore, if less than a
full load of samples is run, it is important to load
samples into the CentriVap in a fairly symmetrical
manner distributing the weight of the samples evenly in
the sample rotor.
Heat Setting Guidelines
The evaporation rate achieved by the CentriVap is
dependent upon a variety of factors. These include the
nature of the solvent, the temperature and the pressure
in the vacuum system.
