Dispensing Type Peristaltic Pump - Card Structure Four Channel (0.00011–49 mL/min)

Introduction

The BT-F Series is a dispensing-type peristaltic pump, mainly designed for the accurate metering and quantitative dispensing of liquids. It includes three models: BT100F, BT300F and BT600F, with a rotational speed control accuracy of ≤±0.2%, which can meet the precise dispensing requirements from micro to large liquid volumes.
Adopting a dual-operation design of LCD touch screen and physical keys, the pump is equipped with four core operating modes: Volume Dispensing Mode, Time Dispensing Mode, Flow Mode and Programming Mode. Specifically, the Programming Mode enables the implementation of complex experimental procedures through customizing cycle control processes, meeting diverse experimental requirements.
It supports multiple control modes including RS485 communication control and external signal input control, and is integrated with suck-back and flow calibration functions to further ensure dispensing accuracy. Featuring a stainless steel housing with corrosion resistance and easy cleaning, the BT-F Series is widely applicable to fluid handling scenarios in laboratories, industrial production and other fields.

Features

• DG6-4 Pump Head (Shift Type): The Shift Type card features a ratchet adjustment structure with multiple color-coded settings, allowing the pressure tube gap to be easily adjusted for different tube materials and sizes. It helps the pump tube work at an ideal compression gap without complex setup, improving flow stability and extending tube service life. For higher outlet pressure, users can simply reduce the tube gap through the adjustment settings.
• Core Parameters: Compatible with a wide range of pump tubes, including Silicone, Pharmed, PVC, Viton, and more, with wall thicknesses of 0.8-1 mm and inner diameters from 0.13-3.17 mm. With a speed range of 0.1-100 rpm, it delivers an ultra-wide single-channel flow range of 0.00011-49 mL/min, making it ideal for both micro-flow dosing and broader precision fluid transfer applications.
• Humanized Design: Dual-operation with LCD touchscreen and physical buttons for intuitive data display and easy operation. Stainless steel housing: corrosion-resistant and easy to clean.
• Four Working Modes: Volume Dispensing Mode, Time Dispensing Mode, Flow Mode and Programming Mode. Specifically, the Programming Mode enables the implementation of complex experimental procedures through customizing cycle control processes, meeting diverse experimental requirements.
• Wide Voltage Design: Adapts to complex power supply environments. Circuit board with three-proof paint coating for dustproof and moisture-proof performance, ensuring high stability.
• Multiple Control Compatibility: Supports RS485 communication (Modbus protocol), external control signal input (0-5V/0-10V/4-20mA), etc.
• Practical Functions: Equipped with basic suck-back and flow calibration functions. For other settings and functions, please refer to the product manual for details.

FAQ

1.Which card structure is the default for this pump head?

The default option on this product page is Shift Type. If you need Spring Type, please leave a note with your order.

• Shift Type:Features a ratchet-adjustable structure with visible settings, allowing the tube compression gap to be manually adjusted according to tube size, wall thickness, and transfer pressure requirements. It offers greater flexibility for different tubing materials, specifications, and pressure needs. Please refer to the user manual for adjustment instructions.
• Spring Type:Features a self-adaptive spring design that automatically adjusts the tube compression gap according to the tube wall thickness. It is easy to use and requires no manual adjustment, making it suitable for standard applications and fixed tubing setups.

2.How many channels does this peristaltic pump have?

This peristaltic pump is four-channel, equipped with a DG6-4 pump head that can hold 4 tubes at the same time. The flow rate and total volume displayed on the panel are for one single channel, and all channels run at the same synchronized flow rate (no independent control for each channel).

3.What tubing sizes and materials is this pump head compatible with, and what is the flow range?

This pump head is compatible with various tubing materials, including Silicone, Pharmed, PVC, and Viton, with wall thicknesses of 0.8-1 mm and inner diameters of 0.13-3.17 mm. At a speed range of 0.1-100 rpm, it delivers a wide single-channel flow range of 0.00011-49 mL/min. When purchasing this product, you can choose one tubing size and receive a total of 8 meters free of charge (2 meters per channel, 4 tubes in total). Please leave a note with your order indicating the tubing size you need. For supported tubing sizes, please refer to the user manual.

4.What does DG6-4 Pump Head mean?

DG6-4 indicates a pump head with 6 rollers and 4 channels.

5.What type of peristaltic pump is this? What are the four working modes?

The BT-F Series is a dispensing-type peristaltic pump that integrates all functions of basic speed-regulating peristaltic pumps. It mainly supports four working modes:

• Flow Mode:The pump operates continuously at a set flow rate and records the cumulative liquid volume. The flow rate and its unit are configurable, and the flow rate can also be adjusted by setting the rotation speed. Delayed start and timed stop are supported.
• Time Dispensing Mode:The pump automatically calculates and dispenses the liquid volume by setting the operating time and flow rate.
• Volume Dispensing Mode:The pump automatically calculates the dispensing time and dispenses the liquid by setting the target volume and flow rate.
• Programming Mode:The pump automatically executes each pre-set step in sequence by defining the operational steps and cycle count.

6.Does it support external control?

Yes. Please note that the buttons and knobs will no longer work after switching to external control mode. In this mode, only start/stop, direction reversal, and speed adjustment can be controlled externally; the timing function is not supported in external control mode. For any questions regarding external control and communication control, please refer to the product manual or contact our customer service directly.

7.Does it have a timing function?

TYes, it supports timing functions. In flow mode, you can set delayed start and scheduled stop. For example, to start automatically after a 30‑minute delay and stop automatically after running for 1.5 hours, simply tap the time display and set the delay start and running time in the pop‑up dialog box.

8.BT‑L vs BT‑F Series Differences?

BT‑F = dispensing‑type (includes all BT‑L flow‑type functions) + Volume Dispensing & Programming Modes. BT‑L is flow‑type with basic dispensing, a cost‑effective choice.

9.Does it have a anti-drip setting?

Yes, this peristaltic pump is equipped with a basic anti-drip (suck-back) function. When the pump stops working, the motor will rotate in the reverse direction by a certain angle to suck back the liquid in the tubing and prevent dripping. Users can set the suck-back angle (0°, 180°, 360°, 720°, or a custom angle) in the system parameters—setting the angle to 0° will disable this function. Meanwhile, the suck-back speed can be adjusted to meet the suck-back needs of liquids with different viscosities.

10.Does it support flow calibration?

Yes, it supports basic flow calibration (note: manual testing and calibration required). For detailed operation instructions, please refer to the user manual.
