Longer BT100-3J Basic Peristaltic Pump

Overview

The Longer BT100-3J Basic Peristaltic Pump is a benchtop, speed-controlled pumping system designed for laboratory liquid transfer, circulation and experimental fluid handling. It operates at 0.1–100 rpm and supports interchangeable pump heads and tubing configurations, providing a manufacturer-specified flow range of 0.0002–380 mL/min across compatible setups. Local keypad operation, external control options and an RS485 communication interface make it suitable for manually operated experiments and compatible automated systems.

How the BT100-3J Works

The BT100-3J uses a motor-driven pump head to compress flexible tubing progressively, moving liquid through the tubing as the rollers rotate.

The liquid remains within the tubing during pumping, rather than contacting the drive mechanism. This can simplify fluid-path selection and maintenance, provided the tubing and other wetted components are compatible with the liquid.

The BT100-3J controls motor speed, not a directly calibrated flow-rate setpoint. Actual liquid flow depends on pump speed, pump-head geometry, tubing dimensions, fluid properties and system resistance.

Key Features

• Adjustable speed: 0.1–100 rpm with 0.1 rpm setting resolution.
• Reversible operation: Clockwise and counter-clockwise rotation.
• Interchangeable pump heads: Supports specified YZ, YZII, BZ, DG, DG15 and DMD15-13 configurations.
• Maximum flow: Up to 380 mL/min per channel with a suitable pump-head and tubing combination.
• Local operation: Membrane keypad and three-digit LED speed display.
• External control: Supports start/stop, direction and speed control using compatible control accessories.
• Communication: RS485 interface for integration with suitable control systems.
• Prime function: Provides rapid filling or emptying of the tubing.
• Parameter memory: Retains operating settings according to the manufacturer's specified behaviour.

Pump Heads and Tubing Configurations

The BT100-3J can be configured with different compatible pump heads to accommodate different tubing sizes and flow requirements.

Compatible pump-head example	Manufacturer maximum flow
YZ1515x / YZII15	380 mL/min
YZ2515x / YZII25	270 mL/min
DMD15-13-B / DMD15-13-D	350 mL/min
DG series, 6-roller configuration	48 mL/min per channel

These are manufacturer reference maxima for specified configurations, not guaranteed flow rates for all liquids or tubing selections.

The required pump head, tubing and accessories should be confirmed before ordering. They must not be assumed to be included with every drive configuration.

Typical Applications

The BT100-3J can be considered for:

• Laboratory liquid transfer and recirculation
• Experimental flow-cell liquid circulation
• Reagent feeding into compatible laboratory reactors
• Analytical and sample-preparation workflows
• Teaching laboratories and method development
• Compatible electrochemical and flow-chemistry experiments

For electrochemical electrolytes or chemically aggressive liquids, the tubing material, connectors, allowable system pressure and operating conditions must be reviewed before use.

Selection and Integration Guidance

When selecting a BT100-3J configuration, first establish the required flow range, liquid composition, tubing dimensions, expected operating duration and whether reversible flow is needed.

The pump can be operated locally or integrated with suitable external controls. Analogue-control modules, communication accessories and external equipment compatibility should be confirmed for the intended installation.

For applications requiring direct flow-rate setting, calibration or programmed volume dispensing, a dedicated flow-rate or dispensing pump may be more appropriate.

Frequently Asked Questions

What is the maximum flow rate of the BT100-3J?

The manufacturer specifies up to 380 mL/min per channel when a suitable pump head and tubing configuration is used. Other configurations have different flow limits.

Does the BT100-3J directly control flow rate?

It primarily controls motor speed. Actual flow rate depends on the head, tubing and operating conditions. The manufacturer does not specify built-in flow-rate calibration for this model.

Can different pump heads be fitted?

Yes. The manufacturer lists several compatible pump-head families, including YZ, YZII, BZ, DG and DMD15-13. The exact head must be selected for the required tubing and flow range.

Is the pump suitable for electrochemical flow cells?

It may be suitable for compatible flow-cell circulation experiments. Tubing chemical resistance, required flow, backpressure and allowable pulsation must be assessed for the specific setup.

Can the pump be controlled remotely?

The BT100-3J provides RS485 communication and supports external operating signals through applicable interfaces and accessories. Integration requirements must be confirmed.

Does the pump automatically dispense a precisely programmed volume?

The BT100-3J is primarily a speed-controlled pump. For applications needing calibrated flow-rate control or programmed dispensing volumes, another pump family may be more suitable.

What information is needed for a quotation?

Provide the liquid being pumped, required minimum and maximum flow rates, tubing preference, operating conditions, number of channels and whether manual or external control is required.
