Ucallm 96 Well Low Attachment Plate, Black Well/ Clear Bottom
Material and construction feature premium polystyrene that is transparent for easy visual inspection. The material is non-toxic and biologically inert, ensuring a safe cell environment. Sterile packaging supports contamination-free workflows.
Best for: non-adherent culture, organoids, and rare-sample storage. The flat-bottom design supports uniform imaging and consistent well geometry. Caution: some strongly adhesive cells may require pre-conditioning or alternative coatings for initial attachment.
Ucallm 96 Well Low Attachment Plate, Clear U-Bottom
Polystyrene plates provide transparency with sterile packaging. The ultra-low adsorption surface minimizes cell attachment, activation, and protein absorption, supporting non-adherent culture and organoids.
Best for: organoid and spheroid work where bottom geometry aids sample handling. Better for imaging due to clear U-bottom wells. Limitation: U-bottom formats may slightly complicate adherent cell workflows.
Ucallm 6 Well Low Attachment Plate
The 6-well format mirrors standard culture workflows while preserving low attachment properties. The plate is designed for non-adherent culture and can support organoids, spheroids, and rare samples with reliable performance.
Best for: smaller-scale experiments or pilot studies. Choose this if you want familiarity with conventional plate formats. Caution: fewer wells mean smaller sample throughput compared to 96-well formats.
POLLOIE 48-Well Ultra-Low Attachment Plate
Constructed from high-quantity polystyrene with an ergonomic design. The 48-well format supports higher throughput while maintaining ultra-low attachment surfaces for non-adherent cultures.
Best for: labs needing more wells without stepping up to 96-well. Caution: surface treatment varies; verify TC treatment status if adherence is required for your assay.
Ucallm 96 Well Flat-Bottom TC Treated Plate
Flat-bottom 96-well TC treated plates offer hydrophilic surfaces that promote cell attachment and proliferation for adherent cell cultures. The plate remains sterile and is available in treated and untreated variants for experimental flexibility.
Best for: adherent cell growth with robust attachment needs. Avoid this if a non-adherent workflow is essential; opt for ultra-low attachment versions instead.
POLLOIE 96-Well U-Shaped Bottom Plate
The 96-well design with a U-shaped bottom is optimized for certain assays and imaging requirements. It provides a distinct well geometry to support specific experimental needs while maintaining low attachment properties.
Best for: assays that benefit from U-shaped well geometry. Caution: bottom shape may influence dispensing or imaging tools; ensure compatibility with your workflow.
Buying Guide
- Purpose and workflow: Choose a plate based on whether you need non-adherent culture, organoids, spheroids, or adherent cell assays. Ultra-low attachment plates are best for non-adherent work, while TC-treated plates suit adherent cells.
- Bottom geometry: Flat bottoms are ideal for uniform imaging; U-bottoms can aid sample collection and specific imaging angles; V-bottoms offer another geometry option for particular assays. Consider instrument compatibility and imaging needs.
- Well configuration: 96-well plates enable higher throughput; 6- or 48-well plates suit smaller experiments or pilot studies. Matching the plate to your throughput goals improves efficiency.
- Material and sterility: Premium polystyrene ensures clear visualization and inertness. Confirm sterile packaging and single-use wrapping if contamination control is critical for your protocol.
- Treatment status: Some plates are tissue culture treated to promote adherence; others are untreated for non-adherent work. Plan according to whether cells require attachment.
- Sample compatibility and volume: Check well volume capacity and whether the geometry affects reagent dispensing, aspiration, or imaging workflows in your setup.
FAQ
- What is a low attachment plate and when should I use one? Answer: A low attachment plate reduces cell adhesion to the surface, supporting non-adherent cultures such as stem cell aggregates, organoids, and spheroids. Use it when you want cells to remain in suspension rather than attaching to the plate.
- Are TC-treated plates suitable for all cell types? Answer: TC-treated plates promote attachment for adherent cells. If you work with non-adherent cells, choose untreated or low-attachment surfaces.
- What bottom shape is best for imaging organoids? Answer: Flat bottoms provide uniform imaging planes and straightforward microscopy, while U-bottoms can assist in sample collection. Choose based on your imaging workflow.
- Do these plates come sterile and ready to use? Answer: The plates listed are described as sterile in their product features, but always follow your lab’s sterility procedures before use.
- Is there a difference between flat-bottom and well-bottom designs for assays? Answer: Flat-bottom plates are generally easier for imaging and consistent pipetting, whereas bottom shapes like U- or V-bottom can influence sample handling and assay geometry.
- How do I decide between 96-well and 48-well formats? Answer: 96-well plates offer higher throughput and smaller volumes, suitable for screening. 48-well plates provide a balance between throughput and handling ease for some assays.
