Overview
The rLabS4 Four-Channel Independent Peristaltic Pump delivers precise fluid handling with complete channel independence for demanding laboratory applications. This intelligent peristaltic pump system provides exceptional flexibility with DG pump head compatibility and advanced programmable control features, making it ideal for multi-stream fluid delivery and complex dispensing protocols.
Key Features
Compatible with six different tubing specifications (0.13×0.9, 0.5×0.8, 3.17×0.8, 1×1, 2×1, 3×1mm) using standard DG pump heads. Features advanced scheduling capabilities with 10 programmable time segments for flow rate control and 10 preset distribution parameters that automatically stop upon completion. Each channel offers independent calibration for enhanced accuracy and precision. External control interface enables remote operation, while selectable USB or RS485 communication protocols provide seamless integration with laboratory automation systems.
Applications
Perfect for analytical chemistry, bioprocessing, and research applications requiring precise multi-channel fluid delivery. Ideal for automated sample preparation, reagent addition, cell culture media delivery, and continuous flow reactions. The independent channel control makes it suitable for parallel processing, gradient formation, and complex fluid handling protocols in pharmaceutical research, environmental testing, and academic laboratories.

What tubing sizes does the rLabS4 accept?
The rLabS4 uses a 10-roller DG pump head and accepts four tubing sizes (inner diameter × wall): 0.5 × 0.8 mm (0.0013–2 mL/min), 1 × 1 mm (0.006–9 mL/min), 2 × 1 mm (0.022–33 mL/min), and 3 × 1 mm (0.032–48 mL/min). The interface shows the maximum achievable flow for whichever tubing is installed, so tubing can be sized to the flow target before a run starts.
Can each of the four channels run a different program?
Yes. Every channel is fully independent, with its own speed, flow, and calibration parameters. Each channel can be assigned its own work mode (flow, timed + fixed-quantity, timed + fixed-speed, or fixed-quantity + fixed-speed) and run concurrently with the others. Individual channels can be closed from the touchscreen and reopened later without disturbing the rest.
How do I integrate the rLabS4 with a laboratory automation system?
The pump exposes both RS485 and USB communication interfaces and accepts external start/stop via a dedicated control line or footswitch. Because flow and speed can be adjusted online while the pump is running, it can be driven from an external controller — for example, closing a dosing loop based on a pH, OD, or temperature reading.
How precise is flow control at low speeds?
Speed resolution is 0.01 rpm across the full 0.01–150 rpm range, and each channel is individually calibrated. With 0.5 × 0.8 mm tubing this delivers stable flows down to approximately 1.3 µL/min, which makes the rLabS4 appropriate for microfluidic feeding, organoid perfusion, and slow-drip infusion protocols.
Does the touchscreen store protocols between runs?
Yes. Calibration parameters are stored per channel, and the fixed-quantity and timed work modes retain their setpoints, so a protocol configured once can be recalled on the next run. The 5-inch color touchscreen also shows live flow rate and remaining time for timed and fixed-quantity runs, so the pump can be checked against the programmed volume.
Is the pump head included with the rLabS4?
Yes. The rLabS4 features an integrated 10-roller pump head — no separate pump head purchase is needed.
