This height adjustable sample pipe assembly consists of an assembly holder for 6 mm tubes (B4-71002-2T9-M10), and a 6 mm OD x 0.78 mm ID sample tube.

This sample pipe has a very small dead volume. The height adjustable sample pipe can be used with or without a sample screen. If it is used without a sample screen, the small dead volume of the pipe guarantees samples from the culture that are representative for the reactor.

If a sample screen is used at the end of this pipe, cell-free samples can be drawn from the culture. Sample screens are available in several pore sizes.

Compatible with 7-20liter Vessel, 10mm Port.

Vessel operation at elevated temperature combined with aeration of the culture might cause too much evaporation during a run (increasing the nutrient concentration and decreasing volume); this can be prevented by using an air-outlet condenser.
