Description
DG series are designed for small flow and multi-channel fluid transfer, easy to install and replace tubing. Self adapting spring adjusts pressing gap automatically according to the tubing size. The rollers are made of 304 stainless steel. A pump head consists of three parts: frame, roller device and cartridge. According to the numbers of channel, there are DG1, DG2, DG4, DG8, DG12, DG16, DG24.
Features
- Multi-channel transfer
- Change tubing easily

- Occlusion can be adjusted slightly by ratchet wheel to fit different tubing wall thicknesses requirements.
- 6-roller and 10-roller pump heads available.
- More rollers reduce pulsation and flow rates slightly.
- Skillful trigger structure, convenient to eject the cartridges.
