96-Well Silicone Sealing Mat for Square-Well Deep-Well Plates

96-Well Silicone Sealing Mat for Square-Well Deep-Well Plates for Sample Storage and Deep-Well Workflows

The Puretest 96-well square-well silicone sealing mat is a flexible, non-adhesive closure for compatible square-well deep-well plates. Ninety-six molded square plugs align with individual wells to help control evaporation, splash and cross-well exposure during storage and processing.

The mat contains a precise 8 × 12 array of square sealing plugs connected by a flexible silicone web. Square plugs maximize contact around matching square well openings and are not intended for round-well plates.

Product Highlights

• Dedicated square-plug geometry: Designed for selected 96-well square-well deep-well plates.
• Flexible research-grade silicone: Applies localized sealing pressure while conforming to the plate surface.
• 96 independent plugs: Provides well-by-well closure in a standard 8 × 12 array.
• Non-adhesive seal: Avoids a pressure-sensitive adhesive layer above the sample wells.
• Pierceable construction: Supports validated access by compatible probes or needles.
• Wide nominal temperature range: Suitable for evaluated workflows from approximately −80 °C to +120 °C.
• Reusable option: May be cleaned and reused when chemistry and contamination controls allow.
• Fit-validation support: Samples and current drawings are available for plate matching.

Mat Structure and Functional Design

The mat contains a precise 8 × 12 array of square sealing plugs connected by a flexible silicone web. Square plugs maximize contact around matching square well openings and are not intended for round-well plates.

Each molded plug enters one well opening and applies localized sealing pressure around the rim. The flexible perimeter and connecting web allow the mat to follow the plate surface while the 8 × 12 plug array maintains well-by-well separation.

Technical Specifications

Temperature range and compatibility are nominal. Confirm the current Puretest drawing, plate match, material statement, cleaning limits and packaging before validation or production ordering.

Application Guide

Plate Compatibility and Selection

Designed for selected 96-well square-well deep-well plates. Square-well products vary in capacity, rim width, corner radius and overall plate height, so a generic 96-well description is not sufficient. Match the plate catalog number and drawings before ordering.

• Match the plug shape to the well opening; do not substitute a round-well mat for a square-well plate.
• Confirm plate capacity, rim shape, overall height, well pitch and plug depth.
• For piercing workflows, validate needle diameter, penetration force, coring risk and resealing behavior.
• For freezing or heated incubation, validate the complete plate–mat–sample system through the intended cycle.
• Use a clamping or compression solution when the transport or incubation protocol requires it.

Installation, Cleaning and Reuse

1. Inspect the mat for cuts, deformation, particles or residual chemicals.
2. Align the 8 × 12 plug array with the plate and press evenly from the center toward the edges.
3. Confirm that every plug is seated and that the mat lies flat before storage, mixing or transport.
4. After use, clean only with a validated protocol compatible with the samples and silicone.
5. Replace the mat if plugs become torn, permanently stretched, discolored or difficult to seat.

Material, Cleaning and Quality Documentation

The sealing mats are molded from research-grade silicone selected for flexibility, temperature resistance and repeated plate engagement. The standard configuration contains no pressure-sensitive adhesive, helping avoid adhesive contact with samples.

Reusable and autoclave-compatible supply may be available, but the permitted cleaning chemistry, number of reuse cycles, temperature exposure and sterility status depend on the quoted configuration. Request the current specification and validate the mat with your sample chemistry before reuse.

If a Certificate of Analysis, Certificate of Conformance, material statement, extractables information, irradiation record or batch traceability is required, state it before ordering so Puretest can confirm the documentation that applies to the selected SKU.

Ordering Information, Packaging and OEM Support

Puretest supports evaluation samples, current technical drawings, bulk and protected packaging, sterile and non-sterile options where available, customer catalog numbers, private labels, barcodes and distributor carton programs. MOQ, inner-pack quantity, case quantity, lead time and carton dimensions are confirmed with the final specification.

Round-Well vs. Square-Well Sealing Mat

Round- and square-well mats are not interchangeable. Confirm the plate catalog number, well opening, rim geometry, plug depth and current drawings before ordering.

Frequently Asked Questions

Can the square-plug mat fit a round-well plate?

No. The plug and rim geometry are different; use the dedicated round-well mat.

Does it fit every 2.2 mL deep-well plate?

No. Plate manufacturers use different rim and well geometries. Confirm a drawing and sample fit.

Is the mat pierceable?

The silicone construction is designed to be pierceable, but validate the probe diameter, force, coring risk and reseal requirement.

How should it be cleaned?

Use only a validated protocol compatible with the sample chemistry and silicone; inspect the mat before reuse.

Are sterile mats available?

Sterile and non-sterile configurations can be discussed and must be stated on the quotation.
