Centrifan TM PE Personal Evaporator 2-1
Chapter 2 Installation
2.1 Overview
Note: The Centrifan TM PE Personal Evaporator is designed to be installed by the
user.
This chapter describes general information about the location and the physical
requirements of the system.
2.2 Location of the System
The Centrifan TM PE Personal Evaporator should be installed in a facility with the following
environmental conditions:
• The temperature range of the laboratory should be between 15 o C and 25 o C (59 o F -
77 o F). The system should be installed in an area in which the temperature range is
fairly constant (the suggested temperature variation is +/- 2 o C/hr (+/- 5 o F/hr)).
• The system should not be placed near a window, air conditioning duct, etc. or any
device in which significant temperature changes may occur (e.g. an oven). The
relative humidity of the area should meet the ASHRE standard for human comfort.
• If flammable solvents are to be used at any stage of the operation of the system,
suitable ventilation should be provided and open flames must be prohibited in the
laboratory.
• Corrosive vapors, solvents and dust should not be allowed in the laboratory as these
can affect system performance.
The general guidelines provided above apply to typical installations. In certain special
applications such as drying proteins and peptides, it may be desirable to place the unit in
a refrigerator to maintain near-0°C conditions to minimize degradation.
The unit has been tested at the aqueous freezing point and the heater has sufficient
power to raise the temperature about 35°C above ambient. In other words, to achieve a
peptide evaporation environment of 9°C the Centrifan
TM PE could be placed in a 4°C
refrigerator and the temperature controller set for 9°C.
2.3 Space Requirements
The dimensions of the Centrifan TM PE Personal Evaporator are 12” (30.5 cm) W x 18”
(45.7 cm) H x 8” (20.3 cm) D. Some clearance to the front of the unit should be provided
to set the temperature control and to operate the lid latch for the loading and unloading of
sample vials.
