Polystyrene Crystal-Clear Lids 782152 by BrandTech 4.5mm Pack of 50

Description

Product Overview

The BrandTech Polystyrene crystal-clear lids are engineered to meet the demanding requirements of modern cell culture laboratories. Constructed from high-purity polystyrene (PS), each lid offers exceptional optical clarity, allowing researchers to monitor cell growth and assay results without removing the lid. The lids are designed without condensation rings, eliminating the common issue of water droplets that can obscure visual inspection and interfere with experimental accuracy. With a uniform height of 4.5 mm, they provide a snug fit for both 96-well and 384-well plates that feature transparent bottoms, ensuring a consistent seal while maintaining the plate’s low-profile design. Each pack contains 50 lids, offering a cost-effective solution for high-throughput workflows.

Key specifications include a package dimension of 10.6 x 5.7 x 4.1 inches and a lightweight of 0.48 ounces per lid, facilitating easy handling and storage. The product model number 782152 aligns with BrandTech’s extensive catalog of laboratory consumables, and the ASIN B009EIPX4W provides a reliable reference for ordering and inventory management. The lids have earned a Best Sellers Rank of #60 in Lab Cell Culture Dishes, reflecting their popularity among researchers seeking dependable, high-quality consumables.

Usage

These lids are ideally suited for a wide range of cell culture applications, including routine maintenance of adherent and suspension cell lines, high-content screening assays, and time-lapse microscopy. Their crystal-clear construction enables uninterrupted observation of cell morphology and confluency, while the absence of condensation rings ensures that optical pathways remain unobstructed throughout incubation periods. The lids are compatible with standard incubators, biosafety cabinets, and automated plate handling systems, making them a versatile choice for both manual and robotic workflows.

In addition to cell culture, the lids can be employed in biochemical assays that require a sealed environment, such as ELISA, luminescence, and fluorescence-based readouts. The sterile, individually wrapped packaging guarantees that each lid remains contaminant-free until use, supporting stringent aseptic techniques. Researchers working with sensitive primary cells, stem cells, or genetically modified lines will appreciate the lids’ ability to maintain a stable microenvironment, reducing the risk of cross-contamination and preserving experimental integrity.

Why Choose Us

BrandTech is committed to delivering laboratory consumables that adhere to the highest standards of quality and safety. All of our cell culture plates and lids undergo ß‑radiation sterilization in compliance with ISO 11137 and AAMI guidelines, achieving a sterility assurance level (SAL) of 10⁻²⁷. This rigorous process eliminates microbial contaminants while preserving the material properties of the polystyrene, ensuring that the lids remain chemically inert and free from leachable substances.

Our lids are also DNA‑, DNase‑, and RNase‑free, meeting the stringent requirements of DIN EN ISO 11014 for cytotoxic substance levels. This guarantees that downstream molecular biology applications, such as PCR, qPCR, and nucleic acid extraction, are not compromised by residual nucleases or contaminants. Each lid is individually wrapped, providing a convenient, ready-to-use solution that minimizes handling time and reduces the potential for accidental exposure to non‑sterile surfaces.

Beyond the technical specifications, BrandTech offers responsive customer support and a comprehensive after‑sales service program. Our technical team is available to assist with product selection, troubleshooting, and protocol optimization, ensuring that laboratories can achieve reliable results with confidence. By choosing BrandTech, researchers gain access to a trusted partner dedicated to advancing scientific discovery through superior consumable design.

FAQ

Are the lids compatible with all brands of 96‑well and 384‑well plates?

The lids are designed to fit standard plate dimensions that conform to industry specifications. While they are fully compatible with most major brands, we recommend verifying the plate footprint if using a non‑standard format.

Can the lids be autoclaved if additional sterilization is required?

Because the lids are already sterilized by ß‑radiation, autoclaving is not necessary and may affect the optical clarity of the polystyrene. We advise using the lids as supplied to maintain their crystal‑clear properties.

What is the recommended storage condition for the lids?

Store the individually wrapped lids in a cool, dry environment away from direct sunlight. Maintaining a temperature between 15 °C and 25 °C helps preserve the material integrity and sterility of the product.

Do the lids interfere with fluorescence or luminescence measurements?

No. The high optical clarity of the polystyrene material ensures minimal background interference, making the lids suitable for a wide range of fluorescence, luminescence, and absorbance assays.

How does BrandTech ensure the lids remain nucleic‑acid free?

All lids undergo rigorous testing to confirm they are DNA‑, DNase‑, and RNase‑free, complying with DIN EN ISO 11014 standards. This guarantees that nucleic‑acid based experiments are not compromised by contaminating enzymes.
