SILICONE SEALING MATS
- Produced from the highest quality research grade silicone, they are specially designed to provide a positive and airtight seal.
- Mats fit tightly into wells preventing evaporation.
- Pare well with automation as-well-as manual laboratory protocols.
- High quality silicone, resists coring and tearing reducing the risk or mat particulate entering the well.
- Well perforations will seal themselves, after penetration, ensuring an airtight closure.
- Made of research-grade silicone, they can be autoclaved, and following a 10% bleach wash and ethanol rinse protocol may be reused.
- Printed alpha numeric grid for easy reference.
- RNase, DNase, DNA, and Pyrogen Free Certification
- Temperature Range: -40C to 80C
Limited volume inserts are available in either glass or polypropylene and both conical and flat bottom varieties. For inserts with polymer bottom spring, the spring acts as a shock absorber that protects against breakage if the needle bottoms out. The conical inserts permit complete sample removal.

20mL Clear Headspace Vial with Flat bottom
Consistently and Quality Made with Affordable Prices: Excellence in Chromatography
Standard 20mm aluminum seal Headspace Vials with Flat Bottoms that form a tight seal with closure for accurate analysis and reproducible results. They are especially useful to heat the samples until the concentration of the gas and liquid phases are in equilibrium so samples can then be taken from the gas phase (headspace).
Clear Headspace Vials with Flat bottoms are available in clear type I borosilicate glass with crimp finishes and can be perfectly sealed with 20 mm Poly Crimp⢠Seal or Aluminum Seals - use with Agilent, Hewlett-Packard, Carlo Erba, Perkin Elmer and Shimadzu analyzers.
These vials make an excellent choice to daily chromatographic experiments in the lab combining the highest quality and consistent results with low cost. A must have for your research.
- Type: Standard Headspace Vial
- Volume: 20mL
- Vial dimensions (diameter x height): 23mm x 75mm
- Bottom: Flat
- Crimp: 20mm
- Color: Clear
- Material: Borosilicate Glass
Polypropylene R.A.M. Limited volume vials are 2 mL overall, but with a working volume of 100 uL. These vials accept 9 mm screw caps. Compatible with most autosamplers including Agilent.

Buy 5 Cases of TPP Cryo Tubes
and Get a PR1MA™ Cooler Cryo Rack Free! (#Rack-Cryo-F)
Valid through December 31, 2022 - Institutional pricing not valid. All terms apply.
TPP Polar Cryogenic Tubes
Perfect for long term storage of Cell lines or Harvested Tissues in the freezer or cryogenic dewars (LN2 vapor phase)
- Pronounced external thread for gas and aerosol tight seal
- Enables a fitted seal to prevent leaking during storage, transportation or centrifugation
- Protects sample integrity by reducing contamination
- The external threading results in a smooth internal surface that eliminates undue loss of specimen material during removal.
- Uniquely designed vial geometry voids the use of silicone gaskets
- Self-standing tube with star bottom permits one handed opening/closing
- Manufactured with the highest quality of virgin raw materials
- Minimizes sample interaction with the centrifuge tube material and prevents leaching that decreases sample integrity
- No additives, slip agents, biocides or plasticizers are utilized in the manufacturing process
- White writing surface for easy labeling
- On side of tube permits detailed description labeling
- Ideal pairing with labeling TPP cap inserts
- Highly visible white & accurate graduations
- Supplied in convenient, puncture and tear resistant re-closable bags with zipper and laser perforation
- Permits ergonomic open/close under sterile conditions
- Application based options available
- Cell line freezing & long term storage
- Sample storage and secure transport
- Long term storage of harvested tissues
Quality Assurance:
- Sterile (gamma irradiated)
- DNAse/RNAse, pyrogen, and heavy metal-free
Recommendations:
- Always use appropriate safety equipment and practices when handling frozen polar tubes
- TPP Polar Tubes are to be used for storage in the gas/vapor phase
- Avoid filling up the Polar Tubes to the maximal filling volume to avoid spillage of liquid sample due to expansion of liquids upon freezing
