Introduction

Biotage® Liquid Level Sensor
Using radar technology, the Biotage® Liquid Level Sensor measures the distance between the sensor (mounted on the reservoir cap) and the liquid level, enabling the system to present the actual amount of liquid available in the reservoir in real time. With the liquid level sensor hub installed on your Selekt or Selekt Enkel system, and its functionality enabled in the system settings, the sensors can be used to monitor the liquid levels in the solvent reservoirs and/or the waste reservoir connected to your system (see Figure 1). For the reservoirs to be used with the liquid level sensors, they must be defined and calibrated in the Reservoir Administration view. The software comes with two preconfigured reservoirs supplied by Biotage. Custom reservoirs can be defined and calibrated on one system and transferred to other Selekt and Selekt Enkel systems using a USB memory device or network share (if enabled).

Reservoirs are assigned to the solvent inlets and waste
outlets in the Solvent Setup view; see page 11. The status of the connected liquid level sensors is displayed both in the Solvent Setup view and the About view (see page 12).

Solvent Notifications and Stop Limits Based on Distance
The solvent notifications and stop limits are based on the distance between the solvent surface and the bottom of the reservoir. This optimizes how much solvent that can be used without the risk of aspirating air. For more information, see page 13.

Safety Stop Limit for Waste
To ensure that the waste reservoir cannot be overfilled, the pump operation in progress is immediately paused if the distance between the sensor and the waste liquid becomes smaller than allowed. This is useful if e.g. the operator by mistake is using a waste reservoir that is smaller than the one that has been assigned to the solvent inlet in the software.

Included in the Kit
Five are delivered with the Biotage® Selekt Liquid Level Sensor Kit (P/N 418776) and three with the Biotage® Selekt Enkel Liquid Level Sensor Kit (P/N 418843). Note that the required caps are not included in the kit and have to be ordered separately, see “Consumables and Accessories” on page 16. We recommend that the boxes and packing materials be kept by the customer in case the kit needs to be shipped in the future.

Note: If solvent/waste monitoring is enabled, it is based on the pumped volume. The current liquid level must be entered each time you refill/empty the reservoir. The connected liquid level sensor is open (flipped up) and/or the assigned reservoir is not calibrated (see reservoirs S3 and S4 in Figure 25). The monitoring is based on the pumped volume. The current liquid level must be entered each time you refill/empty the reservoir. The connected liquid level sensor is used. The connected liquid level sensor failed to detect the liquid level. Check the following:

  • Ensure that the reservoir’s liquid level is stable.
  • Ensure that the reservoir is not tilted.
  • Ensure that the tubing is properly inserted into the reservoir and that there is nothing disturbing the sensor; see steps 2 through 4 on page 5.
  • Ensure that there is no liquid on the bottom of the sensor house that can disturb the sensor readings.
  • Dry off any liquid using a clean, lint-free cloth.
  • Ensure that the sensor is properly closed; see Figure 8 on page 6.
  • Rotate the sensor (and tube holder) into another position, e.g. rotate it 90 degrees, to see if that solves the problem.

The monitoring is based on the pumped volume until the problem has been solved. If the problem has not been solved after using 20% of the set reservoir capacity, the run will be paused and the user notified. Resolve the problem or run without the sensor by flipping it up.
Note: To be able to flip up the sensor, push on the tube holder as shown in Figure 29 on page 14. Sensor failure. The sensor must be disconnected from the liquid-level sensor hub. (The user is notified

Solvent and Waste Notifications

When using the liquid level sensors for solvent and waste monitoring:

Notification Description
The solvent surface is 60 mm from the bottom of the reservoir. In this example, the notification is for solvent inlets S1 and S2. When the solvent surface is 30 mm from the bottom of the reservoir, the run is automatically paused and the user will be prompted to refill the solvent(s). The solvent monitoring has been turned off for the rest of the run by the user. The monitoring is automatically turned on again when the run has been completed.

The waste level is above 85% of the set waste reservoir capacity. When the waste level is at 95% of the set capacity, the run is automatically paused and the user will be prompted to empty the waste reservoir. When the distance between the sensor and the waste liquid becomes smaller than allowed, the run is automatically paused and the user will be prompted to empty the waste reservoir. See “Safety Stop Limit for Waste” below.

Safety Stop Limit for Waste
To ensure that the waste reservoir cannot be overfilled, the pump operation in progress is immediately paused if the distance between the sensor and the waste liquid becomes smaller than allowed. This is useful if e.g. the operator by mistake is using a waste reservoir that is smaller than the one that has been assigned to the solvent inlet in the software.

Refill a Solvent Reservoir
Refill a solvent reservoir by flipping up the sensor; see Figure 29 and Figure 30. This can be done at any time without pausing. When the sensor is closed again, the amount of liquid available in the reservoir is automatically updated in the software Figure 29. Push on the tube holder to be able to flip up (open) the sensor. Figure 30. Refill a solvent reservoir at any time using a funnel. Empty the Waste Reservoir Always ensure that the system is idle or paused when emptying the waste reservoir. Empty the waste reservoir by unscrewing the whole liquid-level sensor assembly; see Figure 31. The run is automatically paused when the waste level is 95% of the set capacity. When the liquid level sensor assembly is attached to the reservoir again (with the sensor closed), the amount of liquid available in the reservoir is automatically updated in the software.

2BBWS418536-Liquid-Level-Sensor-for-Biotage-Select-Family-fig-
\(34\)

Replace a Solvent or Waste Reservoir
Always ensure that the system is idle or paused when replacing a solvent or waste reservoir. Either move the whole liquid level sensor assembly to the new reservoir by unscrewing the cap (see Figure 31) or detach the tube holder from the cap (see Figure 32) and attach the assembly to the new reservoir using a GL45 cap (P/N 418528SP) or a 38-430 cap (P/N 418529SP) supplied by Biotage.
Note : When replacing the reservoir with another type of reservoir, ensure to reassign the reservoir type in the Solvent Setup view (see page 11).

Figure 31. Remove the whole liquid-level sensor assembly by unscrewing the cap. The cap rotates freely, independent of the attached tub holder and sensor. Figure 32. Detach the tube holder from the cap. When the liquid level sensor assembly is attached to a reservoir again (with the sensor closed), the amount of liquid available in the reservoir is automatically updated in the software.
