Z160 Multicultivator

Z160-OD Multi-Cultivator

Z160-OD Multi-Cultivator is designed for small-scale cultivation of algae, bacteria, or cyanobacteria. It consists of 8 vessels, each holding up to ca. 85 ml of cultivated suspension. The vessels are immersed in a temperature-controlled water bath. Each vessel is illuminated by an array of cool white LEDs that can generate incident irradiance, which is independently adjustable up to 1000 µmol(photon)/m2/s. Different white colors of LEDs are also available. Each vessel can be bubbled with gas. The composition of the gas may be controlled with an optional gas mixing system. The gas is humidified and supplied to the vessel through a manually adjustable valve manifold. Continuous culture is also available with the optional Turbidostat module.

The Z160 Multi-Cultivator is supplied with a light controlling unit that supports user-defined dynamic illumination protocols, such as, flashing lights or day/night cycles. Optional accessories are available such as: Cooling Unit AC-700, which serves for the water bath cooling below ambient levels.  The water pump for automatic water bath refilling (maintains constant water level in the bath). Turbidostat module allows continuous growth of the cultures according to predefined density conditions.  MC software and Control PC allow live data visualization and control of experiments in multiple units.   Each Multicultivator measures optical density (OD) at 680 and 720nm for each culture vessel.  OD readings are used for monitoring of cultures’ growth rates.  Simple OD View Software is included with the unit for downloading of the data to PC computer if the unit is purchased without the controller PC and MC software.  Two versions of the MC software are available: the Basic version provides control and visualization of data in up to two Z160-OD and the Advanced version can be used to control and visualize data from unlimited number of Multicultivators.

Optional Turbidostat Module may be supplied with Z160-OD for continuous growth of cultures.  It is equipped with a peristaltic pump and 8 valves that are controlled independentely by the MC software for addition of fresh medium to each culture.   Turbidostat module is fully software controlled therefore requires purchase of the optional Basic or Advanced MC Software.

Standard Z160-OD comes with a single color LED’s – cold white, warm white, red 635 nm or blue 470 nm.  Z160-MULTI system is also available where each cultivation slot is furnished with LED-based illumination of different color. Spectrum from 405 nm to 730 nm can be covered. Single cultivation slots are equipped with the dividers so as to eliminate different color penetration.
