Biolab
On-orbit biology lab for microgravity and radiation studies.
Biolab, short for Biological Experiment Laboratory, is a science payload built into a single rack that multiple research teams can use aboard the Columbus laboratory on the International Space Station. It is designed for biological studies involving small plants, small invertebrates, microorganisms, animal cells, and tissue cultures. The facility includes an incubator fitted with centrifuges, which can expose these specimens to controlled levels of acceleration. The goal of such experiments is to determine how microgravity affects organisms at every level, from individual cells up to complex organisms like humans.
The Biolab setup occupies one International Standard Payload Rack inside the European Columbus module. It is split into two main parts: an automated core unit and a manual section for crew interaction. The core unit can run on its own or be controlled remotely from the ground. It contains a large incubator, two centrifuges, a microscope, a spectrophotometer (which measures how much light a sample absorbs at different wavelengths), a sample-handling mechanism, and Automatic Temperature-Controlled Stowage (ATCS) for storing small sample amounts. The manual section includes an Experiment Preparation Unit (EPU), a BioGloveBox (BGB), and additional Temperature Control Units (TCUs) for holding experiment containers and preserving samples.
Experiment containers (ECs) are designed to hold various biological samples and connect to Biolab’s power, data, and life-support systems. Standard ECs measure 6 x 6 x 10 cm, while Advanced ECs, which support video, are 10.8 x 15 x 13.7 cm. The incubator can keep ECs at temperatures between 18 and 40 °C, accurate to within 0.5 °C. The two centrifuges inside the incubator can generate artificial gravity from 0.001 to 2 G (where G is Earth’s surface gravity). An array of LEDs provides white light for illumination and infrared light for observation.
A robotic arm called the Handling Mechanism (HM) moves ECs between the incubator and Biolab’s analytical instruments—the microscope and spectrophotometer. The microscope, controllable by researchers on the ground, has a resolution ranging from 0.6 to 1.8 micrometers, with corresponding field-of-view diameters of 0.25 and 1.0 micrometers. The spectrophotometer uses tungsten and deuterium lamps to analyze light passing through a sample across a spectral range of 220 to 900 nm

Lore & Background
Biolab is integrated into a single International Standard Payload Rack (ISPR) within the European Columbus laboratory, which was launched on space shuttle mission STS-122. The facility is divided into two sections: the automated core unit and the manual section for crew interaction. The core unit includes a large incubator, two centrifuges, a microscope, a spectrophotometer, a sample-handling mechanism, and Automatic Temperature-Controlled Stowage (ATCS). The manual section consists of the Experiment Preparation Unit (EPU), the BioGloveBox (BGB), and additional Temperature Control Units (TCUs).
The incubator maintains experiment containers (ECs) at temperatures between 18 and 40 °C with an accuracy of 0.5 °C. The two centrifuges inside the incubator provide artificial gravity in the range of 0.001 to 2 G. Biolab's Handling Mechanism (HM) is a robotic arm that interfaces ECs with the microscope and spectrophotometer. The microscope has a resolution from 0.6 to 1.8 micrometers, and the spectrophotometer analyzes light in the spectral range of 220 to 900 nm. The BGB allows manipulation of experiment hardware in a closed, controlled environment and provides disinfection using an ozone gas unit.
Reader's Guide
Biolab enables scientists to study the effects of microgravity and space radiation on unicellular and multicellular organisms, including bacteria, insects, protists, seeds, and cells. Results from Biolab experiments could affect biomedical research in areas such as immunology, pharmacology, bone demineralization, cellular signal transduction, cellular repair, and biotechnology. By providing an incubator, centrifuges for artificial gravity, and analytical instruments like a microscope and spectrophotometer, Biolab allows controlled experiments that help identify the role of microgravity from the single-cell level up to complex organisms including humans. Its automated and manual sections support both autonomous operation and crew interaction, making it a versatile tool for long-term space biology research.

Purpose & Scientific Mission
Biolab exists to answer a fundamental question: how does the absence of gravity reshape living systems at every scale? From single bacteria to small invertebrates, from seeds to tissue cultures, the facility lets researchers isolate microgravity's influence on organisms ranging from unicellular protists to complex multicellular life. The ultimate goal is understanding what microgravity does at every level of biological organization, from individual cell behavior all the way up to whole organisms, including humans. Findings from these in-orbit studies feed directly into terrestrial biomedical fields—immunology, pharmacology, bone demineralization, cellular signal transduction, cellular repair mechanisms, and biotechnology. By studying organisms under controlled space conditions, scientists gain insights that are simply impossible to replicate in ground-based laboratories.
Architecture & Design Philosophy
Biolab is housed within a single International Standard Payload Rack inside the European Columbus module, and its internal layout is split into two distinct zones. The automated core unit handles the heavy analytical work and can run entirely on its own or be directed by ground-based operators. It houses a large incubator, two centrifuges, a microscope, a spectrophotometer, a sample-handling robotic mechanism, and a temperature-controlled stowage system for preserving small samples. The manual section, by contrast, is built around crew interaction. It contains an Experiment Preparation Unit, a BioGloveBox with a 32-liter working volume and ozone-based disinfection, and additional temperature control units for storing experiment containers before and after use. Experiment containers themselves come in two sizes—a standard 6×6×10 cm format and a larger Advanced version at 10.8×15×13.7 cm that supports video recording—each serving as the interface between biological samples and the facility's power, data, and life-support systems.
Operational Capabilities & Precision Control
What sets Biolab apart is the precision with which it can manipulate its experimental environment. The incubator holds experiment containers at temperatures between 18 and 40 degrees Celsius with half-a-degree accuracy, while the stowage and temperature control units maintain a range from minus 20 to 10 degrees Celsius within a one-degree tolerance. Two centrifuges inside the incubator generate artificial gravity spanning 0.001 to 2 G, letting researchers compare microgravity effects against controlled acceleration. An array of LEDs provides white-light illumination and infrared observation for each container. The Handling Mechanism, a robotic arm, shuttles samples between the incubator, the microscope (resolving features from 0.6 to 1.8 micrometers), and the spectrophotometer (analyzing wavelengths from 220 to 900 nanometers with 10-nanometer resolution). The BioGloveBox's Thermo-Electrical Unit keeps its interior between 21 and 38 degrees Celsius, and the entire life-support system regulates atmospheric composition and humidity around the samples.
Deployment & Broader Impact
Biolab did not ride to orbit on its own dedicated flight. It was pre-installed inside the Columbus laboratory module, which Space Shuttle Atlantis delivered to the International Space Station on February 9, 2008, during Assembly Flight 1E (mission STS-122). From that moment forward, the facility became a permanent fixture of European space-based biology research. Its existence on the ISS means that experiments with small plants, invertebrates, microorganisms, animal cells, and tissue cultures can be conducted continuously, with results feeding back into Earth-bound science. Published research connected to Biolab and related ISS payloads has explored topics as varied as small-animal experiments in space and the development of hardware for studying biological clock systems in scorpions under microgravity. By providing a repeatable, controlled on-orbit platform, Biolab bridges the gap between ground-based biology and the unique conditions of spaceflight, expanding what scientists can learn about the fundamental mechanics of life.
