Vials, Septa

The micro-inserts made of first hydrolytic class glass are suitable for

• Short thread vials ND9, with wide opening made of glass or plastic
• Screw neck vials ND10, with wide opening
• Crimp neck vials ND11, with wide opening
• Snap ring vials ND11, with wide opening
• Shell vials, with a nominal volume of 2 ml

The micro-inserts with polymer foot are not suitable for shell vials.

Short thread screw seals ND9 are made of PP and are supplied with fitted septa made of a variety of materials. The caps have a 6 mm centre hole and are available in different colours. The screw caps are similar in shape to the crimp caps and are therefore also suitable for robotic handling.

In this case, caps and septa form an inseparable unit (Ultrabond), which means that even a blunt needle is unable to push the septa into the vial.

These septa are temperature-resistant from -60 °C to 200 °C and have better purity than septa made of red rubber. However, they have less effective resealability properties and are therefore more suitable for single-injection applications.

The LABSOLUTE® kits ND8 contain shrink-wrapped screw vials ND8 with small opening made of clear or amber first hydrolytic class glass and corresponding screw caps made of PP. In some cases, caps are already pre-screwed on the vials.

• Many kits are especially adjusted for use with an autosampler of one defined manufacturer
• Kits with pre-screwed seals reduce the risk of sample contamination
• Kits with pre-assembled micro inserts are available on request

Screw seals ND13 are made of PP and have a 13-425 thread. They have a 8.5 mm centre hole or are closed. Screw seals are supplied with fitted septa made of a variety of materials or without any septa.

These septa are temperature-resistant from -60 °C to 200 °C and have better purity than septa made of natural rubber, butyl or RedRubber. However, they have less effective resealability properties and are therefore more suitable for single-injection applications.

Septa with a double-sided PTFE coating show a very low particle formation during penetration.

The choice of the right septa depends on the application. Many septa are PTFE coated on one side. PTFE is highly resistant against many chemicals and forms an inert border between the sample and the base material of the septa.

The septa's base material has various physical and chemical properties, like temperature resistance, resealability, cleanliness, hardness and thickness.

Natural rubber/TEF

• Temperature-resistant from -40 °C to 120 °C
• Excellent resealability properties
• Inexpensive for standard applications in the fields of GC and HPLC

RedRubber/PTFE

• Temperature-resistant from -30 °C to 110 °C
• Softer and therefore easier to penetrate than natural rubber
• Not as good resealability properties as natural rubber
• Higher chemical purity than natural rubber
• Inexpensive for standard applications in the fields of GC and HPLC

Butyl/PTFE

• Temperature-resistant from -40 °C to 120 °C
• Higher chemical purity than natural rubber and RedRubber

Silicone/PTFE

• Temperature-resistant from -60 °C to 200 °C
• More suitable for single-injection applications
• Much higher chemical purity than natural rubber and RedRubber
• Very low particle formation during penetration in case of double-sided PTFE coating
• Best for the thin and fragile needles of the autosampler
• Best for critical analysis (UltraClean quality)

Septa with a double-sided PTFE coating show a very low particle formation during penetration.

Crimp and headspace seals ND20 are made of aluminium and are supplied with fitted septa made of a variety of materials. There are the following different types of caps available:

Plain caps with a 10 mm center hole. These caps are suitable for standard applications. They are available in several colours on request.

Clear lacquered caps, so called headspace caps, with a special score line that breaks when the internal pressure reaches 3.0 ± 0.5 bar. The excess pressure is then released, and the risk of the vial exploding can be avoided.

Gold lacquered, magnetic crimp caps with 5 mm centre hole to be used with CE HS500/HS800, CTC 500, as well as Fisons HS500 / HS800 instruments.

Gold lacquered, magnetic crimp caps with 8 mm centre hole to be used with CTC Combi PAL instruments.

Red lacquered, magnetic bimetal crimp caps with 8 mm centre hole to be used with CTC Combi PAL instruments.

These dark grey septa are temperature-resistant from -40 °C to 120 °C and have excellent chemical properties. They are 3.0 mm thick and have a hardness of 55° shore A. Because of the missing PTFE coating, the pure butyl septa are an economic alternative for non-critical analysis.
