VELP reserves the right to modify the characteristics of its products with the aim to constantly improving their quality.

Safety Regulations

Connect the instrument using only the supplied external power supply. The plug disconnects the instrument. Therefore, place the instrument where it can be quickly disconnected.

Position the instrument on a flat surface, with a distance from the wall of 30 cm (at least).

Before placing the tube on the stirring cup, make sure that its cap is tightly closed to prevent sample leakage.

The solution may release toxic, dangerous or poisonous gases. Adequate safety measures must be taken, in accordance with the safety regulations in force, including the presence of hood and personal protective equipment (masks, gloves, goggles, etc.).

Do not use with explosive and dangerous materials for which the equipment is not designed. The stirrer must not be used in explosive atmospheres.

Keep hand/arm vibration to a minimum (Directive 2002/44/EC) when operated manually:

• Keep the sample container as vertical as possible.
• Only exert the minimum pressure necessary for the mixing process.
• Use attachments for multiple samples when there is a large number of samples.

Introduction

Mixing by spinning can be carried out quickly and safely by placing the tube containing the sample on the mixing cup head. The Vortex Mixer with LCD display can be used in automatic (SENSOR) or continuous mode (TIMER): in both cases the mixing speed can be adjusted using the speed selector knob (1).
When the instrument is switch on, it is always set in SENSOR mode. Mixing starts when the test-tube crosses the infrared The instrument is factory set to continuous mode (Timer), mixing starts automatically when the speed selector / settings knob is pressed. To select Sensor mode, rotate the knob to highlight “Sensor” on the display, press the knob to activate the operating mode selected. Mixing starts when the test-tube crosses the infrared sensor field (5) near the mixing cup head (4). The press-on fitting means that the mixing cup head can easily be replaced by any of the various accessories available for test-tubes of different sizes.

Assembly and installation

Check the integrity of the unit after unpacking. The box includes:

• TX4 Digital IR Vortex Mixer with mixing cup head.
• Power supply 100-240V/12V no plug.
• EU adapter plug.
• Instruction manual.

Electrical connections

After having unpacked the instrument, place the unit on the laboratory bench.
Before connecting the instrument to the power supply, make sure that the values on the rating plate correspond to those of the power supply. Connect the unit to the power supply using the transformer supplied.
Ensure that the socket and the relative cut-off device conform to current safety norms and are easy to reach.

Start-up

Check that the mixing cup head is correctly positioned. Also check that the speed regulation knob is turned to “0 rpm”. Use the on-off switch on the front of the unit to turn the unit on (position “ON”). The start-up and the control of the speed are effected with the knob. When switched on the unit will automatically start in the last operating mode set (Timer / Sensor).

Operating controls

Connect the unit to mains and turn it on using the on-off switch. Select the operating mode using the mode select button on the front of the unit.

When Timer mode is selected, the timer can be set and the mixing cup head runs continuously at the set speed.
When the Touch mode is selected, mixing starts automatically when the test- tube crosses the sensor field (infrared optical system) shown in Figure 2.

In both operating modes there is no need for any pressure on the mixing cup head. The sensor field is purpose-designed to detect the presence of any kind of test-tube.
NOTE: in case of black-out, the device will not automatically restart after the break and reconnect the power supply.

SETTINGS KNOB

With the instrument in stand-by, turn the knob to select and modify the operating parameters (rpm, timer, Start and Sensor) (Fig. 3). With the instrument running, turn the knob to increase or decrease the speed from 0 to 3000rpm or from 0 to 800rpm  depending on the full-scale setting. Press the speed selector / settings knob to start or stop mixing in Timer mode (Start or Stop highlighted – Fig 4), to select the operating mode (Sensor or Timer highlighted – Fig 5) and/or to modify speed and time parameters (rpm or timer highlighted – Fig 6 and 7). With the timer highlighted (Fig. 7), turn the knob to set the time from 1 second to 999min. and 59 seconds in Timer mode. During use the display will show the countdown and then END (Fig. 9). To disactivate the time keep the speed selector / settings knob pressed for 3 seconds. The display will show — : –: mixing will be active for an infinite time. When a parameter is highlighted (Fig. 3), keep the knob pressed for 3 seconds to set the max speed (Fig. 8). This function can be used in Timer mode only. Use the 800rpm full scale setting if you are using a platform. When Timer is highlighted (Fig. 5), keep the knob pressed for 3 seconds to set the sensor time from 1 second to 999min. and 59 seconds (Fig. 10), this function can be used in Sensor mode only. The display shows the countdown and mixing stops automatically.

The on-off switch turns the unit on and off. If the switch is in the “OFF” position the unit is off; if the switch is in the “ON” position the unit is on.
Always turn the unit off after use.

Maintenance

No routine or extraordinary maintenance is necessary apart from periodically cleaning the unit as described in this manual. In compliance with the product guarantee law, repairs to our units must be carried out in our factory, unless previously agreed otherwise with local distributors.
To replace the cup head, pull it upwards and off. The other push-fit accessories can then be inserted.
The instrument must be transported in its original packaging and any indications present on the original packaging must be followed (e.g. palletized).
It is the responsibility of the user, to properly decontaminate the unit in case of hazardous substances remaining on the surface or interior of the device. If in doubt about the compatibility of a cleaning or decontamination product, contact the manufacturer or distributor.
