Designed for secure sealing of 96-well deep well plates during sample storage, transport, and heat sealing applications. Hawach 96-well plate sealing mats are manufactured from high-grade silicone rubber. They provide a tight, reusable seal that prevents evaporation, cross-contamination, and sample loss. Ideal for PCR plate storage, deep well plate transportation, and automated liquid handling workflows.

Round well sealing mats (26081001 & 26081002): Designed for standard round-bottom 96-well deep well plates. The circular plug fits snugly into each well, creating a reliable seal against evaporation.
Square well sealing mat (26081003): Designed for square-well deep well plates (common in some automation platforms and storage applications). The square profile maximizes surface contact for a secure fit.
| Cat. No. | Well Diameter | Recommended Plate Type | Application |
| 26081001 | 7.3mm | 96-well round well plates (narrow wells) | Standard PCR plates, round bottom storage plates |
| 26081002 | 8.3mm | 96-well round well plates (standard / wider wells) | Deep well plates, sample collection plates |
| 26081003 | 8.4mm (square) | 96-well square well plates | Square-well deep well plates, automation-compatible storage |
To ensure optimal sealing performance, measure the inner diameter of your 96-well plate wells before selecting a sealing mat. The mat’s plug diameter should be slightly larger (0.1-0.3mm) than the well opening to create a compression seal. For square wells, the diagonal measurement is the critical dimension.
Seal deep well plates containing biological samples (DNA, RNA, proteins) to prevent evaporation and contamination during long-term storage at -20°C to 80°C.
Used as a temporary seal during thermal cycling or as a reusable alternative to adhesive films for PCR plate storage.
Compatible with robotic plate handlers – mats provide a secure seal for plates during automated sample transfers.
Silicone material resists many organic solvents and acids, making it suitable for chemical compound storage plates.
Can be washed and reused multiple times – reduces consumable costs.
Sterilize at 121°C for 20 minutes – maintain sterility between uses.
Compression fit prevents sample evaporation and cross-well contamination.
Silicone withstands many solvents, alcohols, and mild acids.
Maintains flexibility from -50°C to +200°C – suitable for freezer storage and heat sealing.
Sample residue does not adhere – easy cleaning.

Round well mats are designed for standard round-bottom 96-well plates. Square well mats are for square-well deep well plates, commonly used in automation and high-density storage. The well shape must match the mat shape for a proper seal.
Measure the inner diameter of your plate’s wells. If the well opening is approximately 7.2-7.5mm, choose 26081001 (Φ7.3mm). If the opening is 8.2-8.5mm, choose 26081002 (Φ8.3mm). The mat plug should be slightly larger than the well for compression sealing.
Yes – the mat is reusable. With proper cleaning (mild detergent, rinse, air dry), it can be used 50+ cycles. Autoclaving between uses extends lifespan.
MOQ is 1 carton (50 sheets). Sample packs (1 box = 10 sheets) are available for evaluation.
Yes – sample packs (1 box = 10 sheets) available. Shipping fee may apply.
Please verify your plate’s well diameter and shape. If uncertain, contact us with your plate model or dimensions – we will confirm compatibility.
These mats are intended for storage and transportation, not as a lid during thermal cycling. For active PCR sealing, use adhesive films or cap strips.
Wash with mild detergent and warm water, rinse thoroughly, and air dry. For sterilization, autoclave (121°C, 20 min) or wipe with 70% ethanol.
