-
- Commodity name: TSP-2AU, TSP-2BU Dual-Channel High-Precision Microstepping Syringe Pump
Micro-step control, suitable for high-precision, low-volume liquid transfer with a flow rate range of 0.00062 nL/min to 21.83 mL/min.
Product Introduction
◆ The TSP-2AU is a dual-channel infusion-type syringe pump, while the TSP-2BU is a dual-channel withdrawal/infusion-type syringe pump with microstep control, ideal for high-precision, low-volume liquid delivery.
◆ Flow range: 0.00062 nL/min – 21.83 mL/min
◆ Applicable syringes: 0.5 µL – 60 mL
◆ Touchscreen display: 4.3-inch HD touchscreen, simple, clear, and easy to operate.
◆ Syringe Selection: Built-in syringe specifications from major domestic and international manufacturers are available for selection, and custom syringes are also supported.
◆ Calibration function: Supports liquid volume calibration and stores calibration parameters.
◆ Parameter settings: liquid volume, flow rate, injection time, withdrawal time, interval time, number of injections, and other parameters.
◆ Working modes: Four optional working modes—Injection, Withdrawal, Withdraw first then inject, and Inject first then withdraw.
◆ Multiple scenarios can be pre-stored for easy recall.
◆ Reminder function: When the set liquid volume is reached, an audible alarm will sound to notify you.
◆ External Control Start/Stop: External control level signals or contact signals are used to achieve start/stop control.
◆ Communication Control: RS485/USB Optional

Syringe Selection Built-in syringes from major domestic and international manufacturers are available for selection, and custom options are supported. Parameter Settings Liquid volume, flow rate, injection time, withdrawal time, interval time, and number of injections can be set and stored. Scheme storage Pre-store multiple solutions for easy retrieval. Online speed adjustment During operation, if you change the running speed or running time, confirm the changes and then execute using the new parameters. Reminder function Run to the set target liquid volume, with an audible alarm prompt. Appointment feature Automatically start and run at the set date and time. External control function Start-stop control is managed by external signals or contacts; control modes include: high level, low level, and pulse—selectable. Communication control RS485/USB optional; touch-screen settings for address and baud rate.
