Chromatography Direct’s new ultra-low bleed silicone products are essential for users who have had problems with Butyl rubber coring and resulting instrument blockages, needle damage or splintering with their existing septa, extra interfering peaks on repeat injections, or have issues with changes in the peak area on repeat injections.

Chromatography Direct’s new ultra-low bleed silicone products feature:

  • Significantly lower levels of siloxanes than other products in the market
  • Improved seal and resealing for repeat injections when subjected to Butyl rubber products
  • Anti-coring to prevent septa plugs from blocking the instrument flow path, thus further reducing instrument downtime
  • Lower extractables than Butyl rubber when performing repeat injections

The product is also available in 96-well mats.
