Achieving a stable, homogeneous, and perfectly controlled light exposure for photosynthetic cultures is often a challenge: insufficient intensity, uneven illumination, difficulty reproducing day/night cycles, chamber overheating… Kuhner SUN is specifically designed to address these challenges.
Developed for Kuhner ISF1-Z Compressor incubator shaker, it delivers a powerful and uniform illumination of up to 321 µmol s⁻¹ m⁻². The independent control of two LED channels allows you to create realistic and reproducible lighting conditions tailored to each type of photosynthetic cell culture or microorganism – without complex installation or additional equipment.
Whether you’re cultivating microalgae, plant cells, or phototrophic bacteria, you can fine tune the light conditions with precision. Adjust intensity in seconds and shape your spectrum by blending warm (3000 K) and cool (6500 K) white light to precisely match the requirements of your cultures.
Optimal conditions and full control to promote growth, trigger metabolic pathways, or study specific light responses.
No external timers required. Built-in day/night programs with sunrise and sunset simulation deliver stable, reproducible photoperiods—essential for generating comparable results across experiments.
Eliminates external timers, reduces errors, and
guarantees identical conditions from one experiment to the next.
Less than ±7% variation across the platform: every culture receives the same amount of light.
Low variability and high reliability mean greater confidence in your results.
To prevent overheating Kuhner SUN will automatically activate dual cooling as necessary.
The cultivation temperature remains at its set point, even at high light intensities.
Quick installation, no modification of the ISF1-Z, a user-friendly touchscreen interface, and manual, programmed, or automated lighting modes.
A flexible and efficient solution that integrates seamlessly into any laboratory.
New Technology
Retrofitting
Optimize growth, light spectrum, and photoperiod. Perform reliable screening or prepare cultures before scaling up to a photobioreactor. Boost production of high-value pigments (e.g., Astaxanthin) and biomass via light-stress cycles.
Stable results and better control of key parameters.
Exemplary organisms: E.g., Haematococcus, Dunaliella, Spirulina, Chlorella.
Gentle, constant, and homogeneous lighting for studying photosynthesis, metabolite production, or gene expression. Ideal for molecular farming, green cell lines, greening of (e.g., BY-2 cells), and light-inducible protein expression.
Ideal for sensitive cell lines and demanding protocols.
Exemplary organisms: E.g. Nicotiana tabacum, Physcomitrium patens, Marchantia polymorpha.
Precisely defined spectrum & calibrated intensity to analyze metabolic pathways, pigment biosynthesis, or photofermentation. Control anoxygenic photosynthesis for hydrogen production, bioplastics, and metabolic pathway analysis.
Reproducible conditions for small-scale processes.
Exemplary organisms: E.g., Rhodobacter, Rhodospirillum, Chlorobium.
