Chromlab Analytical® Sample Vials,
Caps and Septa

Chromla® Autosampler vials
Chromlab Analytical® Autosampler vials are manufactured from glass meeting the international standards for hydrolytic extraction, ASTM E-438 Type 1 class A borosilicate glass, compliant with the requirements of U.S. and European Pharmacopeia which improves your laboratory productivity, by reducing costs and saving time. With a portfolio of over 1500 products to fit different autosampler, our high-quality vials, vial inserts, closures and septa will perform reliably in any application. These products considerably reduce the risk of analytical test results compromised by ghost peaks, damaged needles or dislodged septa, decreasing analysis failures and sample reruns.

Vials Feature

  • Clear glass vials--made from USP Type I, Class A, 33 Borosilicate Expansion glass, with lowest leaching characteristics and a linear coefficient of expansion of 33.
  • Amber glass vials²made from USP Type 1 Class B, 51 Borosilicate Glass. (All amber borosilicate glass is made of Class B unless otherwise specified and has an expansion
  • Dimensional--Computerized camera system for quality control throughout the manufacturing process to test critical dimensions, including Height, Diameter, Bottom Thickness and Neck/Thread.
  • Compatible with a wide range of HPLC, LCMS and GC Instruments.

Chromlab Analytical® Caps/ Septa

Vial cap septa are a critical link to optimal analysis. Each septum is specified to complement the overall system and enhance chemical performance.

Chromlab Analytical® vial cap septa are specially formulated and constructed to provide optimum system performance with minimal coring and superior chemical inertness.

The softness or hardness (durometer) is matched to the instrument and designed to work well with syringes and samples.

The size of the septum is critical to proper sealing. All Chromlab Analytical® septa are specifically sized for proper sealing. Chromlab Analytical® septa have a special detail built into the cap to the specific septa coring and eliminate the need to replace caps with extended usage.

Chromlab Analytical® Cap²made of high quality polyproylene to exact manufacturing tolerances and lined in a controlled manufacturing environment, tested by head space GC to ensure proper curing of silicone polymer
