The GD200-1C Low Flow Rate Dispensing Peristaltic Pump is a precise, multichannel general-purpose dispensing pump designed for laboratory microfluidic applications. Available with DG pump heads in 6-roller and 10-roller configurations for 4 to 24 channels.
General
The GD200-1C is a high-performance peristaltic dispensing pump from Longer, engineered for accurate, repeatable liquid handling at low flow rates. It is the successor to the widely used BT100-1L, providing key upgrades such as a built-in dispensing mode and a convenient 5-inch touchscreen combined with four physical buttons for intuitive and efficient control. The pump supports three operating modes: continuous, time, and volume. It can be operated locally or remotely via RS485/Ethernet, external analog signal, foot switch, or voice command. With an operating noise below 50 dB, the GD200-1C is an ideal platform for dispensing, filling, and metering workflows across a wide range of laboratory environments.
Features & Benefits
- Flow rates: between 0.002 and 48 mL/min
- Channels: from 4 to 24 simultaneous
- Intuitive touchscreen interface: flow rate, run status, and accumulated volume display
- Multiple operating modes: continuous, time, and volume dispensing with calibration features
- Versatile remote control: RS485 / Ethernet communication (Modbus RTU), external analog signal (0–5 V, 0–10 V, 4–20 mA), foot switch, and voice control
- Low-noise: operation below 55 dB
- Programmable: store, name, and recall dispensing recipes directly from the volume mode interface
- Anti-drip feature: to ensure accuracy and minimize sample loss
