Solid phase extraction instrument (SPE80)

1、 Instrument Introduction

He, SPE80， Specifically addressing these issues:
The flow rate is inconsistent, fast and slow, with one column waiting for a long time;
Uneven pressure, often blocked when passing through the column naturally, and uneven manual pressurization;
The plan was designed and the samples were processed, but it was found that the receiving bottle could not fit in;
Threats to health, severe solvent evaporation, dizziness for half a day after completing the experiment;
The operation is complex, with only three to five samples, and it takes time to operate;
Neglecting one aspect and neglecting another, it is difficult to control the batch flow rate, and there is concern that the solvent may dry out;
Busy and flustered, adding solvents without delay, severe liquid splashing and bottle flipping;
Not supporting large volume water sample loading, some samples cannot be made;

2、 Main functional features:
Supports simultaneous processing of samples through 8 channels, controlled by 8 peristaltic pumps, with each channel independently controlled, ensuring uniform pressure and synchronized flow rate;
By using different connection methods, peristaltic pumps can provide positive or negative pressure without the need for manual pressurization;
The extraction platform has automatic lifting function and is compatible with commonly used extraction columns and receiving bottles in the laboratory;
Adopting automatic liquid addition mode, the entire flow path is sealed and non-volatile;
When the sample quantity is small, the quick manual mode can be used to simplify the operation;
One click pause can control the liquid level height of the small column to prevent solvent from drying out;
Support automatic batch addition of solvents and samples, automatic collection without manual intervention;
Accurate control of column passing speed, with a control accuracy of 0.07mL/min;
Adopting an 8-channel synchronous sample pump, the 8-channel speed is uniformly controlled to ensure good parallelism;
Supports 1/3/6/12/30/60mL extraction columns and 47/90mm extraction disks;
Support multiple specifications of receiving bottles, including conventional 15/50mL centrifuge tubes, chicken heart bottles, rotary evaporation bottles, and other containers;
Configure LED display screen to display real-time flow rate, time, and sample pump speed for easy understanding of experimental status;
Support automatic loading of large volume water samples, with a loading volume of over 500mL;
