2.2 mL 8 Tips Comb ( Safe Lock Cap), U-Bottom, Clear

We offer polypropylene (PP). PP offers broader chemical resistance, suitable for most organic solvents and high-temperature applications (e.g., incubation).

We offer non-sterile, radiation-sterilized (SAL 10⁻⁶), and filter-sterilized (with sealing films) options. Sterile products are clearly marked on the packaging.

Yes, the vast majority of our deep well plates comply with ANSI/SLAS dimensional standards and undergo rigorous QC for flatness and well spacing accuracy, ensuring compatibility with mainstream automation systems.

V-bottoms are conically-shaped well bottoms. Sample recovery is optimized with this bottom shape. For this reason plates with V-bottom are especially used for precipitation assays and storage.

A U-bottom is a round-shaped well bottom. This bottom has no edges and is recommended for stirring and washing of samples. This bottom form is used for agglutination and other assays requiring these tasks.

A C-bottom is a flat bottom with curved edges. The C-bottom combines the advantages of U- and F-bottom. Because of the curved edges better sample mixing is obtained. The flat bottom in the middle of the wells at the same time allows the realization of precise optical measurements. The C-bottom is widely used for immunological assays, as sample stirring has a major impact on precise assay results.

Store in a dry place at room temperature, protected from light. For cell culture or sensitive samples, check seal integrity before use. For long-term liquid storage, ensure sealing films are intact and consider suitability for -80°C (validate plate and seal low-temperature tolerance).

Yes. Our plates are designed for centrifugation in standard microplate centrifuges (with appropriate adapters). Do not exceed the maximum RCF specified in the product documentation.

We offer pierceable seals (for sampling), peelable seals (for temporary sealing), and heat seals (for long-term storage and shipping). Selection depends on your application: automated piercing, manual removal, or vapor-phase LN₂ storage.

Our polypropylene plates and compatible silicone mat seals are tested for long-term storage at -80°C. For vapor-phase liquid nitrogen storage, specifically designed heat seals and validated protocols must be used to prevent leakage or breakage.
