Overview of adjustable Flow Splitters

We offer adjustable Flow Splitters for analytical, semi-preparative and preparative applications.

Analytical post-column Flow Splitters for flow rates of 0.25 - 5.0 ml/min

The default inlet flow for calibration is 1.0 ml/min. However, please always specify your inlet flow (0.25 - 5 ml/min) before order. This way we can assure optimum pressure drop across the splitter, even if the inlet flow differs from the default calibration inlet flow rate.
For orders of spare parts please provide the part number and the serial number of the splitter.

Semi-preparative post-column Flow Splitters for flow rates of 5.0 - 40 ml/min

The default inlet flow for calibration is 20.0 ml/min. However, please always specify your inlet flow (5.0 - 40 ml/min) before order. This way we can assure optimum pressure drop across the splitter, even if the inlet flow differs from the default calibration inlet flow rate.
For orders of spare parts please provide the part number and the serial number of the splitter.

Preparative post-column Flow Splitters

The preparative flow splitters are set to a custom split ratio. Therefore, please always specify your inlet flow and the desired split ration before order.
Please note, that the port of the low flow rate outlet has a UNF 10-32 threadi and is for 1/6" OD capillaries. For the ports of the Inlet and the high flow rate outlet we offer also versions with UNF 5/16-24 thread for 1/8" OD capillaries as indicated in the tabel below.
For orders of spare parts please provide the part number and the serial number of the splitter.
