Air inlet pipe used to meet the oxygen demand of a culture. Allows a sterile gas stream to be sparged into the vessel. This is a “drilled hole” or “flute” sparger, which can be used when high gas flow rates are required, as it has a minimal pressure drop. The holes in this pipe are located in the bottom of the tube, to ensure that the medium is driven out by the gas stream.

Compatible with 15 liter Vessel, 10mm port.

Baffles are used to increase the mixing efficiency. Without baffles, the medium flow can become laminar, causing poor mixing efficiency and mass transfer. The baffles are mounted near the reactor wall for optimum mixing performance. The baffle assembly consists of three baffles and mounting hardware.

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.
