DRK-SPE216 Automatic Solid Phase Extraction Instrument

Main functions and features
Number of channels:
The instrument host adopts a modular design, supports the number of on-site upgrade channels, and supports
1/2/4/6/8 multiple channel combinations;
Continuous processing capacity:
Maximum continuous processing of 52 samples;
Robotic arm:
The X/Y/Z/H three-dimensional four-axis mechanical arm design takes into account flexible movement and precise positioning, and the operating noise is less than 50dB. X/Y axis linkage improves operation efficiency; H axis is used to seal the extraction column to ensure the parallelism and reproducibility of samples;
Sample pump:
Accurate sampling, solvent corrosion resistance, high pressure resistance (pressure resistance above 1Mpa), and compatible with large and small sample loading;
Injection needle:
316L stainless steel material, solvent corrosion resistance; support liquid level following function; unique side-bottom opening method to ensure that all samples are loaded; highly integrated functions, can be used for liquid channels, gas channels, and also used for extraction column sealing;
Puncture sampling:
It can realize puncture sampling, avoid sample volatilization loss, protect the health of operators, and be green and environmentally friendly;
Remote connection and control:
The instrument is equipped with a router as standard, which can be connected via Wi-Fi or a network cable, which fully realizes the whole process of automation and unattended operation;
Sample volume and receiving volume:
All products support 10-20ml sample tubes, 50ml and larger sample tubes within two channels; receiving volume 10-15ml, 50ml and larger collection tubes within two channels;
Emergency stop button:
The instrument has an emergency stop button, which can be stopped in an emergency with one button to maximize user safety;
Flow rate control:
The instrument achieves high-pressure sealing through independent sealing cover and pan-plug sealing docking technology. At the same time, each channel is equipped with a pressure sensor, and the push column pressure realizes closed-loop fuzzy control, so that the solution passes through the extraction column at the set flow rate, ensuring good parallelism and reproducibility ;
Pressure Sensor:
With overpressure alarm and termination of the experiment function;
Solvent management system:
Support 8 kinds of reagents; real-time monitoring, prompt of insufficient remaining capacity;
Infiltration and incubation:
After the activation solvent or the elution solvent is loaded on the extraction column, the liquid level can be kept above the packing for a certain period of time to ensure full activation or elution, and to ensure that the ideal experimental results are obtained;
Cleaning mode:
Nitrogen purge, solvent cleaning, blowing and stirring cleaning and other modes are used to clean the inner and outer walls of the sample needle to avoid cross-contamination;
Waste discharge channel:
Support environmentally friendly recycling of waste liquids, and realize separate treatment of waste liquids of different properties;
Extraction column specifications:
Compatible with conventional l/3/6/12ml extraction columns, other specifications of extraction columns can be customized according to requirements;
Multi-scheme extraction:
Support different specifications of extraction columns and different processing items to set up and run at the same time, without waiting, improve the efficiency of continuous processing;
A/B column extraction:
Support multiple modes of string column extraction, and automatically identify the A/B column extraction scheme;
On-line drying/dewatering:
Support dual modes of nitrogen purge and online anhydrous sodium sulfate dewatering;
Online enrichment:
Support in-situ nitrogen purging and concentration, the concentration time can be edited, and the auxiliary concentration can be realized automatically;
Large volume injection:
Support the continuous and stable loading of samples above 500ml, without interruption, particle wear resistance, corrosion resistance, without any consumables and regular maintenance;
cloud service:
Support upload and download plans and parameters; support online technical support and communication;
Remote monitoring:
The instrument is equipped with a router as standard, which can be connected remotely via WiFi or network cable, which fully realizes the whole process of automation and unattended operation;
Appointment start:
After the experiment plan is edited, you can make a self-booking start time according to the analysis instrument machine time;
Intelligent self-check and alarm:
After the parameter setting is completed, the software self-checks whether there is a logic error, and promptly reminds the modification; the intelligent fault alarm system chooses to continue or stop according to the fault level;
