Deepwell Plates

Deepwell Plates

Storage plates, often referred to as deepwell plates, are ideal for short and long-term sample storage, including tissue culture work, enzyme assays, and reagent reservoir uses, handling, and transportation of compounds. They are typically produced in a range of polypropylenes, offering good chemical resistance. However, where lower grade material, or ‘nonvirigin’ polymer has been utilized, they can leach extractable elements from the storage plate wall, providing background noise during analysis.

We carry a comprehensive range of deepwell plates featuring both round and square well bottoms. This provides you the opportunity to select the right solution for your lab — whether you’re looking for incredibly durable, high-quality tubes or economic alternatives for tight budgets or more conservative throughputs.

We invite you to refer to each available product for its specific working volume, temperature storage range, and centrifugation ratings to fit your laboratory’s needs.

The Advantage of Deepwell Plates

The advantage of deepwell plates over tubes is the ability to store numerous samples in a small area, the footprint of which has been outlined by the American National Standards Institute (NASI) as well as the Society for Laboratory Automation and Screen (SLAS). Compliance with these standards ensures you can rest assured that the deepwell plate is suitable for robotic handling, plate readers, and plate handling devices.

All deepwell plates come standard with an alpha-numeric grid along the top and side for reference in sample processing. Storage plate opacity is influenced by the polypropylene used by the molder, not an indicator of material purity. We use medical-grade polypropylene to guarantee consistency and performance to the highest standard. All products are manufactured in medical device certified cleanrooms and are DNase/RNase free.

Formats

Our deepwell formats fall into two distinct categories — square and round well storage. Square wells allow greater well volume, while round wells are functional for content mixing. A further variable in deepwell plate design is the base profile. Typically, square well plates have V-shaped bases to maximize sample extraction, while round well storage plates have U-shaped bases to aid mixing.

Wells

The number of wells in a storage plate has an influence on well volume and height. The most widely used storage plates come with 96 wells in either square or round well format, but the range of plates available also include 24 and 48-well varieties.

To reduce cross contamination and facilitate heat-sealing performance, round well storage plates can come with a raised rim. Alternatively, rimless round well plates are available where these issues are not as much of a concern, or the storage plate is required to house glass vials.
