Software and hardware powers the brilliant system

control tower with integrated software. Culture vessel with functional ports and pipelines

The control tower features at least four built-in peristaltic pumps, with different functions for microbial research (BAILUN500) and cell culture (BAILUN500) respectively. Meanwhile, it’s available both in single (BAILUN500) and dual vessels (BAILUN500) configuration. It can control two same or different volume vessels to work independently at the same time, which greatly increases the flexibility and efficiency.

STAINLESS STEEL JACKETED 5L-5KL OR INTERNAL COIL AND EXTERNAL COIL 5KL-200KLJACKETED

  • Those pumps are set as either alkali, acid, antifoam and feed
  • Constant-rate pump with 60rpm
  • Additionally, external pumps for feeding can be easily connected upon request

Processing Module

Airflow

Utilizing one air flow path, the flow meter intuitively indicates and controls sparger flow rate. An optional mass flow controller can be integrated to control and measure the flow range by manual regulation or automatically in combination with a DO controller.

O2-Enrichment

Utilizing two flow paths for air and O2 flow, the flow meter intuitively indicates and allows manual adjustment of the sparger flow rate. O2 is pulsed through a solenoid valve and flows only as needed to maintain the Dissolved Oxygen (DO) set point. A mass flow controller can be integrated to measure and control the total gas flow range by manual adjustment or automatically combined with a DO controller.

Advanced Gas Flow

Up to 5 gas flow paths. Air goes into overlay through a flow meter and a solenoid valve. At the same time, solenoid valves select air, O2, N2 and CO2 to flow to the sparger. There are two ways to adjust the flow rate. The flow meter can intuitively set the flow rate of each gas path independently and use the solenoid valve as the gas path switch. The optional mass flow meter can automatically measure and control the gas path flow, which makes it possible to set and stabilize the overlay and sparger.
