WebSeal Well Plates and Mats | Thermo Fisher Scientific

Overview

Delivering a new level of performance, reproducibility, and accuracy of results

Modern laboratories need to optimize limited space and maximize analysis time. That means being as efficient as possible with sample handling, sample preparation, and sample transport.

Thermo Scientific SureSTART WebSeal well plates and sealing mats are the perfect solution when there is a need for high throughput and high efficiency in the lab.

Because experiments, analytes, and budgets can vary, we have organized our WebSeal well plates and mats into three performance levels to provide you with the affordability, compatibility, and performance you need.

Performance Level 1: Everyday applications; choose these for the best cost-effectiveness
Performance Level 2: High-throughput applications; ideal for regulated laboratories, choose these when robustness and reproducibility are key
Performance Level 3: High performance; ideal for regulated laboratories, choose these when sensitivity is a must

No HPLC/UHPLC or GC instrument has been left behind. Our well plates are suitable for all vendors' instruments. All WebSeal products are Specification Certified. In addition, well plates are chromatography or LC-MS/GC-MS tested for solvent compatibility and inertness.

Get a sure start with these SureSTART WebSeal products to obtain the performance, reproducibility, and accuracy of results you are looking for. See how our well plate and sealing mat collection delivers a first-class product experience from purchase to final result.
