General Description
The Stuart sample concentrator, when used in conjunction with a Stuart block heater accelerates the evaporation
process of samples of solution for analysis. With the heat generated from the block heater and the steady flow of
gas above the surface of the sample, to carry away evaporated products, the rate of sample concentration is
significantly increased. The Stuart sample concentrator is only compatible with the three block, SBH130D/3 or
SBH200D/3, models of Stuart block heater.
The sample concentrator is made up of gas chamber sited on a height adjustable stand, to allow accurate
positioning above the samples. Hyperdermic needles penetrate a membrane within the gas chamber and carry the
gas from the chamber into the sample test tubes.
Safety Advice Before Use
Care should be taken when using hot apparatus, high temperatures can cause serious burns and ignite
combustible material
Never move or carry the unit when in use
Always use a gas regulator to control the flow of gas to the sample concentrator, do not exceed 2 psi at the
intake valve
Do not put hot objects near combustible objects
Do not place liquid directly into your block heater
Installation
To help reduce packaging material the sample concentrator is delivered in three parts; the base board, the column
and carriage, and the gas chamber. Follow the instructions and diagram below to reassemble:
1.
Unscrew the fastening knob at the rear of the base board, locate the column on the two pins in the
support bracket. Tighten the fastening knob to secure the column in place.
2.
Insert the locating pin at the rear of the gas chamber into gas chamber location hole on the carriage,
taking care to line up the positioning pin, tighten the locking nut at the side of the carriage to secure the
gas chambers position.
