Multi-Cultivator MC 1000-OD serves for small scale cultivation of algae, bacteria or cyanobacteria. It consists of 8 test-tubes, each holding up to ca. 85 ml of cultivated suspension. The test-tubes are immersed in a thermostated waterbath with its temperature being controlled in the range of ambient to 60 °C (optionally lower). Each tube is independently illuminated by an array of cool white LEDs (optionally warm white, red, or blue LEDs) that generate incident irradiance up to 1,000 µmol(photon)/m2.s (optionally up to 2,500 µmol(photon)/m2.s), which is independently adjustable for each test-tube in intensity, timing and modulation.

Growth rate of the cultivated organisms may be estimated by automatic measuring of optical density - measured at 680 nm and 720 nm independently at each cultivation tube. In the standard version, optical density is periodically measured and the data are stored in the Multi-Cultivator internal memory. Stored data may later be downloaded to a PC and displayed in graphs or exported to TXT or Excel files via the program provided. Supported are also user-defined illumination protocols, such as, flashing light or diurnal regime (optional).

Each cultivation tube can be bubbled with air or selected gas (optional) of different flow rate through a manually adjustable valve manifold. Optionally, Multi-Cultivator may be equipped with an additional module for connection to the Gas Mixing System GMS 150 or to an external air pump.

Optionally, the whole Multi-Cultivator system and all its cultivation and monitoring functions (light, temperature, optical density, bubbled gas composition) can be controlled online via the MC control software that provides intuitive and dynamic interface for online monitoring and visualization of all measured data as well as creation of user-defined protocols.

The instrument function can by enhanced by a number of various optional accessories: for instance, Cooling Unit AC-700 serving for the thermostated waterbath cooling; PWM Pump providing for automatic waterbath refilling, Turbidostat Module for continuous cultivation, etc.

Multi-Cultivator MC 1000-OD-MULTI is a NEW multi-color instrument version - 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.

Multi-Cultivator MC 1000-OD-MIX is a NEW mixed-color instrument version which allows to combine up to 4 different LED colors within each cultivation slot for definition of specific spectra.
