ECIS^® Z-Theta

• Complex impedance analyser
• ECIS^® (Electric Cell-substrate Impedance Sensing) quantifies morphology changes in the sub-nanometer to micrometer ranges.
• Small altering currents are applied across an electron pattern at the bottom of the array which results in a potential across the electrodes being measured by the system. Cells act as insulators increasing the impedance.
• Stimulating cells to change their function alter the impedance which can be detected by the system.
• The instrument can use a range of AC-frequencies from 100 to 100 kHz and complex impedance measurement to determine different cell morphology parameters including barrier function, close contacts, and membrane capacitance.
• 16- or 96-well station for use with 8-well or 96-well arrays
• Station is designed to put in an incubator for optimal cell growth. Incubators are also available from Dunn Labortechnik.
• Optional 8-well transfilter array station available (see below)
• Laptop (WIN 11)
• Software for data acquisition and analysis

arge Roller Apparatus and suitable Large Capacity Roll-In CO₂   Incubators from Bellco Glass are the perfect combination for the production of cells, cell products, vaccines, and viruses.

Since many years, Dunn Labortechnik supplies their customers with the well-proven roller apparatus from Bellco Glass and also offers continuous technical support for this equipment.

Especially for biotechnological production, large roller apparatus with 88 bottle positions and suitable large-capacity roll-in incubators with 2,265 liters chamber, digital controllers for speed, temperature and CO₂ , as well as safety thermostat are now available.

For easy operation and process monitoring, both units are equipped with a touch screen display. In addition to local acoustic and visual alarms, incubator model 7728-S0260 has analogue signal and alarm outputs for monitoring via computer or monitoring system as well as USB and Ethernet connections. In addition, an alarm notification can be sent by E-mail or text message. 

The Bellco roller apparatus has a battery back-up system to bridge short-term power failures and can accommodate up to 88 long or up to 176 short roller bottles, depending on process and system configuration. The included all-position drive ensures that even light weight roller bottles are rotated evenly in the selected running direction.
