Frequently Asked Questions (FAQs)

Are bar-coded WebSeal plates available?

Yes, bar-coded WebSeal plates are available as a catalog product for the famly of Thermo Scientific Vanquish UHPLC machines only. However, plates can be provided with a pre-printed adhesive label applied. Contact your sales representative to assist with completing a form where you can define the bar code information and location of application onto the plate. Additional information required includes the physical requirements for the label such as temperature stability, solvent stability, etc.
What is the best way to seal a WebSeal Plate plus or plates with glass or PTFE inserts that need to be incubated at elevated temperatures?

WebSeal Plate+ or plates with glass or PTFE inserts should never be sealed with tapes or adhesive foils. Silicone mats should be used with the WebSeal Plate&plus products, preferably with a protective PTFE film to give increased chemical protection.

The glass inserted plates are sealed with specific silicone plug mats or individual caps. Again, most have additional PTFE films of layers to give increased chemical protection.

These plates, inserts, and mats were originally designed for combinatorial chemistry techniques with in situ chemical derivatization. Use with elevated temperatures is possible with the inserts and plugs. These are the closest plate format equivalent to glass autosampler vial products.

How do the Thermo Scientific-WebSeal Plate plus products compare to standard and certified products?

The WebSeal Plate+ coating provides additional surface protection that further reduces the possibility of interactions with solvents, sample component, or other materials. WebSeal Plate+ microptates display ultra-low background extractable organics profiles that compare favorably to our mass spectrometry certified vial products.
How do WebSeal-Certified low bleed plates compare to others?

Well plates are manufactured in molds. In order to ''force'' the ready produced plate to come out of this mold for the next shot, some manufacturers use release agents (organic compounds that act as lubricants). These release agents can be detected in your chromatogram. The grade of polypropylene used by most plate manufacturers can contain monomers or other added ingredients that are susceptible to leaching on contact with organic solvents. WebSeal-Certified products are manufactured from high purity resins and use a process that does not require mold release agents and that is why they exhbit no significant background extractables.

Do standard WebSeal plates bleed with organic solvents, or is it better to purchase certified plates?

If you are using high concentrations of organic solvents in your sample, then you may be concerned about ''bleed''. This is a term which normally implies a constant loss of material from the column or separation system which leads to high background levels, increased noise, and loss of sensitivity. If using solutions with a high level of buffer or water, then this should not be a concern as such components will not leach under these conditions. All plates may be used.

The evaluation of the plastic resins used in the production of plates was also carried out by controlled extraction of leachable components with organic solvents associated with HPLC and GC operation. These included methanol, acetonitrile, and hexane. Standard plates showed low level of extractables when tested at the highest instrument sensitivity range. These extractables found are characteristic of the common materials used for microplates in the clinical market and plates that have been used for general purpose chromatography applications. This indicates that for many non-critical applications and with higher concentrations of sample, the standard quality plates will be acceptable. These plates are termed Chromatography Tested.

The very low levels of background extractables found during our testing of some plates showed for applications run at more sensitive instrument settings. Where higher purity of the plate is required, you should directly switch to the Certified plates as they are the lowest extraction PP plates currently available on the world market. For critical analysis with high organic solvent concentrations and low sample concentrations, the Certified product range should be the plates of choice.
Are WebSeal products compatible with GC-MS?

When using polymeric sample containers for GC or GC-MS applications, it is always important to consider the impact of background extractable compounds on the analysis. The presence of plasticizers and nucleation agents in the plastic material is the main source of background contamination. Efforts have been made to use only those plastics which are low in such additives.

WebSeal silicone mat products have been extensively evaluated for premium performance with regards to purity. Most work done has been to detemine that the resins are chromatographically acceptable with MeOH, Acetonitrile, and n- Heptane. The conditions we used for creating extractable data (temperature, column, detector, sensitivity, etc.) are published on thermofisher.com/webseal. Review of the chromatographic data will assist you in determining the suitability of specific products. In many cases, we can recommend our products for GC as well as HPLC applications.
Do WebSeal plates work with protein and bio analysis matrix?

The WebSeal plates are not compatible with ELISA and other fluorimetic or luminescent measurements or assays. They are suitable for use as sample collection plates for peptides and other bio-molecules followed by separation on Bio-LC or SEC systems. If the final destination of the sample workflow is an HPLC system, then these are valid product choices. If used for non-chromatographic techniques, then other plate products may be more suitable.
What are the temperature limits for the WebSeal microplate products?

Polypropylene microplates and silicone mats will tolerate exposure to temperatures as low as -80 degrees C and may be stored in cryogenic conditions. Polypropylene microplates and silicone mats will tolerate exposure to temperatures as high as 121 degrees C for up to 15 mins for the purpose of sterilization by autoclaving. The upper temperature limit of these products for extended periods of time (up to 7 days of constant heating) is 100 degrees C.
Can Thermo Scientific WebSeal well plates and mats be used on an automated liquid handling system such as Tecan, Hamilton, and others?

Thermo Scientific Webseal microplate products adhere to the Society for Biomolecular Screening (SBS) microplate formats. Instruments from vendors such as Tecan, Hamilton, Gilson, PerkinElmer, and others can be used within the instrument guidelines.
Does Thermo Fisher Scientific have a compatibility table for autosamplers and WebSeal well plates and mats?

Yes, visit this page (https://assets.thermofisher.com/TFS-Assets/CMD/brochures/TG-Autosampler-Compatibility-Well-Plates-EN.pdf) for a list of chromatography autosamplers that are compatible with microplates.

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.

For more information, please contact your local sales representative or complete the inquiries form at the bottom of the SureSTART Autosampler Vials and Caps page (https://www.thermofisher.com/us/en/home/industrial/chromatography/chromatography-consumables/autosampler-vials-caps-hplc-gc.html).
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.
