Evaporation from unsealed plates during multi-day incubation changes well concentrations, skewing assay results. Contamination from an improperly sealed Petri dish can ruin an entire experiment. DiversifiedBiotech PetriSEAL™ eliminates both risks: it stretches and conforms to form a vapor-tight seal around microtiter plates, Petri dishes, and culture plates, withstands -40°C to +77°C (intermittent to 100°C), resists abrasion and puncture, and leaves zero adhesive residue after two years — so plates can be resealed or relabeled cleanly. Five colors for immediate visual plate color-coding without additional labeling. 1 roll. Made in USA.
Features & Benefits
- Stretches and Conforms — Tight Seal on Any Plate: PetriSEAL™ stretches to wrap tightly around the edges of microtiter plates, Petri dishes, and culture plates of varying heights and geometries, forming a uniform seal without gaps.
- Temperature Range -40°C to +77°C Continuous (to 100°C Intermittent): Remains flexible down to -30°C for sealed plate storage in -20°C and -30°C freezers; withstands incubator temperatures up to 77°C for extended culture periods. Intermittent exposure to 100°C for brief heat-shock or sterilization steps.
- Waterproof & Chemically Resistant: Resists aqueous solutions and common laboratory reagents — sealed plates can be handled, inverted, and stacked without leakage or seal failure.
- Reduces Gas Exchange & Blocks Vapor Loss: Controls evaporation from culture plates during extended incubation — critical for multi-day assays where well volume consistency affects results.
- Abrasion and Puncture Resistant: Durable enough to withstand normal plate handling, stacking, and incubator conditions without tearing or compromising the seal.
- No Adhesive Residue After 2+ Years: Leaves surfaces clean after removal even after prolonged application — important for plates that may need to be accessed or relabeled.
- 5 Colors for Plate Color-Coding: Blue (108B), Clear (108C), Red (108R), White (108W), Yellow (108Y) — assign colors by experiment, sample type, date, or operator for immediate visual plate identification without additional labeling.

Frequently Asked Questions
Can PetriSEAL seal 96-well plates for -80°C storage?
PetriSEAL is rated continuous to -40°C and remains flexible to -30°C. At -80°C it becomes rigid but generally maintains seal integrity on undisturbed plates. For validated -80°C applications, confirm performance with your specific plate type and workflow. PetriSEAL is well-established for -20°C to -30°C plate storage without caveats.
Do the five colors perform identically?
Yes. Blue (108B), Clear (108C), Red (108R), White (108W), and Yellow (108Y) use the same PetriSEAL formulation. Color selection is purely for plate identification — assign by experiment type, date, operator, or treatment group.
