Culture-plate

Culture plates are designed for either adherent or suspension cell culture using polystyrene with surface treatments tailored to cell type. Non-treated plates support suspension cultures by minimizing cell adherence, while tissue culture treated plates promote initial cell attachment and proliferation on hydrophilic surfaces. The plates are manufactured in 6, 12, 24, 48, and 96-well formats with flat bottoms and are gamma irradiated for sterility. Each plate is non-pyrogenic and free from DNase and RNase, ensuring no interference with cell growth or downstream assays.

Two distinct product lines: non-treated for suspension cultures, tissue culture treated for adherent cell growth
Flat bottom design ensures uniform cell distribution and consistent imaging or reading
Gamma radiation sterilization eliminates microbial contamination without chemical residues
Non-pyrogenic and DNase/RNase free to prevent interference with sensitive biological assays

Where It Is Used

Applications And Buyers

Application Scenarios

Growing suspension cells such as lymphocytes or hybridomas in bioreactor or flask-free systems
Maintaining adherent cell lines like HEK293 or CHO cells in high-throughput screening assays
Performing cell viability assays where surface treatment affects cell attachment and growth
Conducting gene expression or protein analysis where residual enzymes could degrade samples
Supporting long-term cell culture experiments requiring sterile, low-extractable surfaces

Who It Is For

Life-science research laboratories developing cell-based assays and drug screening
Biopharmaceutical R&D teams working with both adherent and suspension cell lines
Contract research organisations standardising culture conditions across multiple projects
Academic labs conducting cell biology experiments with strict sterility and purity requirements
OEM partners needing custom packaging or private-label plates for distribution

Problems It Solves

Cell loss or damage in suspension cultures due to unintended adherence to unmodified surfaces
Poor cell attachment and delayed proliferation on untreated surfaces in adherent culture workflows
Contamination from pyrogens or nucleases affecting cell viability or assay results
Inconsistent results across wells due to variable surface properties or residual processing agents
Need to source multiple plate types from different suppliers with varying surface treatments

How It Is Made

Manufacturing And Quality Control

Manufacturing Process

Application of surface treatment (adherent or non-adherent) based on product line
Gamma radiation sterilization of finished plates
Inspection for particulates and surface integrity in a dust-free environment
Packaging in 1/50 or 1/100 configurations depending on well count

Quality Control

Visual inspection of each plate for defects, scratches, or bubbles
Verification of surface treatment type and consistency across batches
Sterility confirmation via gamma irradiation process validation
Testing for non-pyrogenicity and absence of DNase/RNase activity
Check of well volume and growth area against specified dimensions

Comparison

Compared With The Alternatives

Versus Standard polystyrene plates without surface treatment

The tissue culture treated version ensures reliable cell attachment and growth, while non-treated plates prevent unwanted adhesion in suspension cultures

Versus Plates with rounded or V-bottom wells

Flat-bottom design allows for consistent cell distribution and accurate imaging or absorbance readings

Versus Plates from suppliers without nuclease testing

These plates are tested and confirmed DNase/RNase free, which is critical for RNA or DNA-based assays

Use Guide

How To Use It

Select non-treated plates for suspension cell cultures where minimal adherence is required
Choose tissue culture treated plates for adherent cell lines that require strong initial attachment
Use 96-well format for high-throughput screening and 6-well for larger-scale culture or media changes
Ensure all plates are handled with sterile technique after opening to prevent contamination
Avoid prolonged exposure to UV light or high temperatures that may degrade the polystyrene
Store plates in a clean, dry environment below 30°C to maintain surface integrity

FAQ

Questions Buyers Ask

What is the difference between non-treated and tissue culture treated plates?

Non-treated plates resist cell adherence, making them suitable for suspension cultures. Tissue culture treated plates promote cell attachment and proliferation for adherent cell lines.

Are these plates suitable for sensitive assays like RNA analysis?

Yes. The plates are DNase and RNase free, which prevents degradation of nucleic acids during cell culture or harvesting.

What is the sterilization method used?

All plates are sterilized using gamma radiation, which ensures microbial safety without leaving chemical residues.

Can I use these plates for long-term cell culture?

Yes, the plates are designed for standard cell culture durations. For extended culture, ensure proper media changes and sterile handling.

What packaging options are available?

6, 12, 24, and 48-well plates are packed 1 per 50. 96-well plates are packed 1 per 100.

Do you offer private-label or OEM options?

Yes. The Microlab OEM division supports private-label printing, custom packaging, and contract manufacturing for distributor and brand partners.
