Chromatography Vials and Caps

Do users experience coring and resultant instrument blockages with butyl rubber? Do they encounter interfering or extra peaks on repeat injections? Do they experience needle damage or breakage with their existing septa? Do they face issues with differences in the peak region on repeat injections?

If yes, then users should try the latest ultra low bleed silicone products from Chromatography Direct.

Anti-coring prevents plugs of septa blocking instrument flowpath and thus ensures reduced downtime

Considerably decreased levels of siloxanes are present when compared to other products available in the market

Low extractables when compared to butyl rubber when carrying out repeat injection

An improved seal and improved resealing for repeat injections in comparison with butyl rubber products

High Recovery Vials—HRV™

Do users have limited volumes of sample?

Do they find inserts costly and difficult to use?

Do they find one-piece alternatives (nano and fused insert vials) cost-prohibitive?

Then users should try the latest high recovery vials from Chromatography Direct.

Users can sample down to a remaining volume of 4 µL

Reduced manufacturing cost means lower end-user costs against the glass in fused glass insert vials

Fused glass insert vial is available in amber or clear plastic

Snap/crimp or 9-mm screw thread types are provided

Maximum Recovery Vials—MRV™

These vails have been developed particularly for the bottom draw-port needle on systems like the Waters ACQUITY UPLC, Agilent, and the Alliance HT HPLC systems. The Maximum Recovery Vials have been recently added to the Chromatography Direct portfolio.

These vials provide the highest sample capacity with a minimum residual volume. Besides this, 9-mm caps make these vials perfect for use with Agilent GC and HPLC systems.

The vials are available in 9-mm screw-top clear or amber color either with or without labels and crimp-top clear or amber color either with or without a label. They are supplied as individual packs of 1000 caps or vials and also in combi-packs of 100 caps and vials. Solid storage caps and pre-pierced caps are also available.

AntiSpin™ Headspace Crimp Caps

Do users have to carry out repeat injections because of unreliable crimping methods?

Do they need to manually inspect separate headspace caps to ensure that these caps do not spin on the vial?

Do they face interfering peaks because of extractables from the septa material?

If yes, then users should try the latest AntiSpin™ Headspace Crimp Caps from Chromatography Direct.

AntiSpin design guarantees optimal sealing and thus prevents any leakage that will impact calibrations and outcomes

Physical characteristics of the silicone used guarantees a tight seal, irrespective of users’ ability

Comes in standard Silicone/PTF and Ultra-Low Bleed Silicone/PTFE
