Makerworld has significantly reduced the download/print points awarded to designers. Instead, they have introduced the "Boost" token, which you can apply to models that may not be the most popular (already gaining points from downloads and prints), but are useful or meaningful to you in general. This supports and encourages us, the "losers" (those not focusing on popular themes like Star Wars, car keychains, countless airless balls, etc.), to create more useful or niche designs.

Tube holders/racks are among the most common and abundant items in a laboratory environment. Reaction tubes come in different sizes and require specific holders. Here, I present racks/stands/holders to suit the most common applications in a biological laboratory in the format of Kit Cards. These designs feature materials friendly yet rigid and stable for assembly, easy printing & assembly, and have been tested in actual biomedical labs.

This page holds the model for a 4 x 10 FACS/flow cytometry tubes rack.

These models are published separately to:

1. Avoid clutter
2. Facilitate easy searching for the correct items
3. Allow convenient potential updates and troubleshooting.

After all, laboratory vessels come in different sizes and variations, so minor adjustments might be needed for individual cases. Just let me know in the comments, and I will try to resolve them.

Background:

FACS Tubes:
FACS tubes, also known as fluorescence-activated cell sorting tubes, are specialized tubes used in flow cytometry and cell sorting techniques. These tubes are designed to hold cell suspensions that are to be analyzed or sorted based on their fluorescence properties. FACS tubes are typically made of optically clear materials, such as polystyrene or polypropylene, to allow for accurate detection of fluorescence signals emitted by labeled cells.

These tubes are often sterile and free from endotoxins and RNases to maintain cell viability and integrity during sorting and analysis procedures. Additionally, FACS tubes may have caps or plugs to prevent sample spillage and contamination, especially during centrifugation and sorting processes.

Overall, FACS tubes are essential tools in flow cytometry laboratories for precise and efficient analysis, sorting, and isolation of specific cell populations based on their fluorescent properties.

Flow Cytometry:
Flow cytometry is a technique used in biomedical research and clinical diagnostics to analyze and sort cells based on various physical and chemical characteristics. It involves suspending cells in a fluid and passing them through a laser beam one at a time. As cells pass through the laser beam, they scatter light in different directions and emit fluorescence signals depending on their properties. The instrument used in flow cytometry, called a flow cytometer, detects and measures these signals to provide valuable information about the characteristics of individual cells within a heterogeneous population.

FACS (Fluorescence-Activated Cell Sorting) is a specialized application of flow cytometry that allows for the sorting of cells based on their fluorescence signals. In FACS, cells labeled with fluorescent markers are analyzed as they pass through the flow cytometer. Based on the fluorescence signals emitted by the cells, a sorting mechanism selectively diverts cells of interest into separate collection tubes, allowing for the isolation and purification of specific cell populations.

In summary, flow cytometry is a technique used to analyze and sort cells based on their properties, while FACS is a specific application of flow cytometry used for fluorescence-based cell sorting. Both techniques are widely used in biological and medical research to study cell populations and isolate specific cell types for further analysis.

Assembly:
Simply slot the support pillars into the panels. It should be easier than assembling IKEA furniture, and anyone smart enough to be in a lab should have no problem assembling them.
