Effectively seal all microplate formats with Thermo Scientific™ WebSeal™ Sealing Tapes.

Effectively seal all microplate formats with Thermo Scientific™ WebSeal™ Sealing Tapes. Available in a selection of thin, lightweight materials and adhesives to meet the needs of any application or assay, they minimize evaporation and protect samples from contamination and spilling.

Easy, Consistent Sealing

  • Pressure-sensitive adhesive is not tacky to touch, but forms a strong bond to the plate upon application of pressure
  • Tapes seal onto the plate with a convenient, handheld applicator (available separately)

Have the WebSeal mats been tested for evaporation?

Yes, all WebSeal mats that may be used with the WebSeal well plates have been subjected to evaporation tests which are either gravimetric or chromatographic. Gravimetric testing results show the retention of volatile solvents over periods of hours to days. The chromatographic evaluation shows the repeatability of low concentration standards over typical chromatographic analytical cycles.

What is the difference between the SureSTART Performance Level 1, Performance Level 2, and Performance Level 3 vials?

All glass vials found within the three different performance levels are made from Type 1 Class A Borosilicate glass. This type of glass has excellent chemical resistance properties that make it ideal for the containment or storage of acidic, neutral and alkaline samples/analytes. The vials also have high temperature resistance and are suitable for use at temperatures between -50 degrees C to 120 degrees C (although a rapid change in temperature of the products should be avoided).

The Performance Level 1 vials are designed to identify those which are suitable for simple routine, testing with limited budget. Performance Level 1 glass vials have a single wavy line.

For most analytical requirements, the Performance Level 2 products will be suitable for use with higher sensitivity methods while maintaining throughput. Performance Level 2 glass vials have two wavy lines.

For the most stringent analytical requirements, the Performance Level 3 products have advanced features which make them suitable for use with difficult samples in terms of chemistry and available sample volume. All Performance Level 3 products are made from 33-expansion glass and these vials have three wavy lines.

What happened to National, Chromacol, and other brands for chromatogenic workflow accessories?

Many of the products that were branded as National Scientific and Chromacol have been absorbed into the new Thermo Scientific SureSTART Collection, although there are still a few products that still exist within the marketplace.

What is the SureSTART products portfolio for chromatographic workflows?

The SureSTART portfolio is a comprehensive list of vials, caps, inserts, well plates, mats and accessories that are suitable for use with chromatographic workflows. The SureSTART portfolio contains three different performance levels that have been quality checked to provide a robust and reliable product.

The SureSTART portfolio includes products that were previously found in our legacy brands such as National Scientific, Chromacol, and Sun-Sri.
