1. Introduction

Water Bath Concentrator is mainly used for the concentration or preparation of large quantities of samples (such as drug screening, hormone analysis, liquid phase, and sample preparation in mass spectrometry analysis). Working principle: By blowing nitrogen into the surface of the heated sample, the solvent in the sample is quickly evaporated and separated, so as to achieve the purpose of oxygen-free concentration of the sample and keep the sample more pure.
This product has the following characteristics:
★ Elegant appearance, with elevation operation panel, embedded flowmeter, waterproof button, safe and reliable.
★ Good compatibility, suitable for test tubes (diameter 10 ~ 29mm), conical flask, centrifuge tube, the sample capacity of 1 ~ 50ml.
★ Free up and down needle valve tube, independent adjustable needle valve,controls gas flow at each sample location
★ Circular turntable structure, 360-degree rotation, convenient sample support into and out of thewater bath, easy to operate.

3. Basic Operation Instruction

This chapter will introduce the construction of the Instrument, operation panel and the function of all buttons as well as preparing work before starting-up. You should be familiar with this chapter before starting-up when you use the Instrument first time.

3.1 Construction

Front Side

Back Side

3.2 Instrument Installation

3.2.1 Purge gas path installati Installation steps:
1) Put the purge frame vertically on the table.
2) Loosen the holddown nut and insert the telescopic rod into the holddown nut.
3) Connect the gas pipe on the air chamber and the needle valve on the top of telescopic rod, completely inserted the gas pipe into the needle valve.
4) Install the rest 11 telescopic rods in the same way.
5) screw in the gas needle counterclockwise into the bottom of the telescopic rod according to drawing, tighten it with your hands.
3.2.2 Rotating purging frame installation


Installation steps：
1）Put the installed rotating purging frame with gas pipe and gas needles into the inner tank, the support frame base must stack into the Inner tank circle.
2）The height of the purge frame to can be adjusted, release the knob, press down the knob, the purge frame fall, tighten the knob while it down to the appropriate position. If you want to rise, release the knob, the internal spring will automatically raise the purge frame.

3.3 Gas source connection

1) Connect one end of the connect gas pipe to the air chamber inlet joint and the other end to the gas outlet joint behind the control box. The connecting pipe must completely inserted into the air chamber inlet joint and the gas outlet joint.
2) Gas joint is equipped with quick connection function, the user can easily and quickly turn on and off the gas source. Operation is as follows:
As shown in the figure below, press the 2 (Connector) position by hand, then stuffed the 1 (Gas inlet) with the force toward A direction, and the spring component in the connector will automatically clamps against the 1 (Gas inlet). When it is necessary to separate the gas pipe from the gas distribution chamber, simply press and hold the 2 (Connector) to push it toward to B direction, and the spring component in the connector will automatically disengaged from 1 (Gas inlet).

3) Connect the other end of the gas source connection pipe to the gas supply.
4) The steps to connect the gas source is as follows:
A) Adjust the flow adjustment knob first, adjust the size of the total gas inflow volume, counterclockwise rotation to increase the flow, clockwise rotation to reduce the flow until the closure.
B) Adjust the needle valve of any single gas path to turn on or off this gas path, turn counterclockwise to increase the flow, turn clockwise to decrease the flow until it closes. So by adjusting the needle valve can also adjust the size of the gas flow of that gas path.

C) Open the input gas supply valve, turn on the gas, adjust the "flow adjustment knob" and "needle adjustment knob" to the appropriate flow rate as needed.
Note: the pressure of the input gas should not be more than 0.2Mpa, too much pressure of the gas source will make the gas chamber seal bad, so that the gas chamber leak, thus wasting air.
5) After the gas path is connected, add pure water to the water bath and the liquid is about 30mm from the top of the tank.

3.3 Operation panel / Button instruction

Decreasing button: decrease the figure set;
Increasing button: increase the figure set;
START/STOP Run/stop button: Run when you press the button once after setting the temperature and the time. Stop when you press this button for 2s.
Mode When the time is in the timer state, press this key for the untimed status, and display OFF, pressed became timer status when in OFF status.

4. Operation Guide

4.1 Temperature and time set:

a). The LED will display “ ” as the chart when the Instrument powers on and the Instrument goes into the initial state with the sound of “du…”.

b). About 2s later, the figure 28.5 is the block’s current temperature; 00:35 in the time display is the last set time.

Press or near the word “Temp” and keep off at once. Now, the value in the temperature display is the former setting temperature. As shown in the left drawing, the last digital of the setting temperature is flickering. If you want to set the temperature to 55.5℃，do as follows:

Keep pressing , when it reach 55.5°C, stop Pressing , it will auto save as 55.5°C
Keep pressing the above keys for 2 seconds. We can modify the value fleetly. It is very convenient.
c). Press or near the word “Time” and keep off at once. Now, the value in the time display is the former setting time. Shown in the left drawing is 00:35 (35minutes). At same time, the last digital is flickering. If you want to change the time to 01:20, do as follows:

Keep pressing , when it reach 01:20,
stop Pressing , it will auto save as 01:20,
Notes: If the time setting is 00:00, meaning the time of operation is forever, the Instrument run constantly in setting temperature.

4.2 Operation and stop:

a) After accomplishment of the temperature and time setting, press the button of START/STOP and keep off at once, the Instrument begins operating. The temperature rises with the sound of the “du...”.

Meanwhile, there is current temperature in the temperature display, and the radix point is flickering regularly during the rise process.

When the timing is stopped, the operation is also stopped. The buzzer alarms. Current temperature in the temperature display and “ ” in time display mean “over”, the complishment of the operation.

b). After accomplishment of the operation, the instrument is in standby mode waiting for new declaration. Then pressing the keys near “Temp” or “Time” can reset the temperature or the time. Pressing START/STOP, it will operate according to last setting.
c). Press START/STOP for 2s during the operation, it will stop running. Press this button again, operation will continue.
