Vials, Septa

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.

Clear lacquered centre tear-off caps and complete tear-off caps. These caps are available in several colours on request.

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.

Septa made from Viton with a hardness of 70° shore A and a thickness of 1.0 mm have a very high resistance against a wide range of solvents. These septa are highly recommended for use with chlorinated solvents.
Viton septa are not suitable for multiple injections or high injection speeds.

Further crimping heads are available on request.

The crimping and decapping tools feature a chemically resistant surface lacquer that has been developed especially for use in the laboratory. Additionally, the crimping tools have hardened closing jaws with a special alloy that guarantee a long service life. The crimping pressure and crimping height of the crimping tools can also be adapted to the design of the crimp neck and septal thickness.

Further decapping heads are available on request.

Electronic crimpers and decappers provide secure, reproducible crimps and quick and easy removal of aluminium seals. The tools can be used quite mobile because of the built-in rechargeable long life lithium ion battery. Ergonomic design and push button operation eliminates wrist strain especially at large sample series. Adjustable crimp settings make the crimping tool compatible with most vial/seal combinations. The adjusted crimping pressure can be seen easily at any time. A brush-less gear technology guarantees a longer lifetime and less particle emission.

• Vials can be crimped and decapped while they remain in the sample tray
• Tools can be used while recharging
• Universal 100 - 240 V charger included

The GC septa are universal and longlife. They are delivered in resealable screw neck vials of 1^st hydrolytic class and ready-to-use. You have several advantages using our GC septa:

• Suitable for inlet temperatures up to 400 °C
• Low release of siloxanes
• Good penetration and sealing properties
• No sticking to hot surfaces

2in1 KITs contain 100 vials (1.5 ml) and 100 closures in an orange PP-Box. As both components are always required at the same time, 2in1 KITs are a convenient way to obtain and store all required items for analysis. All advantages of the individual components (cleanroom packaging of the vials, recloseability of the packaging, etc.) remain unchanged.

Any other combination of vial and seal as a 2in1 KIT available.

The shell vials made of clear or amber first hydrolytic class glass come in a set with transparent PE plugs. The star-shaped diaphragm in the plug facilitates easy penetration.

Shell vials made of plastic are a shatter-proof alternative to glass vials. They also come with a PE plug.

This easy-to-use, inexpensive vial/plug combination is suitable for non-critical analyses, especially in the field of HPLC.

These micro-inserts made of first hydrolytic class glass are suitable for shell vials only.

The micro-inserts made of transparent PP 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
