Vials, Septa
Septa, 20 mm
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....
Vial racks, PP
The stackable vial racks made of transparent acrylic or blue PP allow the easy handling and secure transport of sample vials.
Transparent acrylic allows the fill level of the sample vials to be easily checked. PP is not transparent, but more robust than acrylic.

Suitable for the following vials:
7.612 175, 7.620 146, 7.621 813, 6.204 710, 7.620 148, 7.620 147, 7.612 926, 7.615 808, 7.616 552 and 7.616 883....
Kit for titration according to Karl-Fischer
The LABSOLUTE® kit ND20 consists of crimp neck vials made of clear glass of the first hydrolytic class and corresponding aluminum crimp closures with an ultraclean septum made of silicone/PTFE. The special dimensions of the vials and the modification of the closures are perfectly adapted for the use with the Metrohm 774 & 874 Oven Sample Processor for the determination of the water content according to Karl-Fischer....
LLG-2in1 KITs with Screw Neck Vials ND8 (small opening)
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....
Crimp seals ND13
Crimp seals ND13 are made of aluminium. They are clear lacquered and have a 6 mm centre hole, a centre tear-off or complete tear-off. They are supplied with fitted septa made of a variety of materials.
The septa made of silicone white/PTFE red are temperature-resistant from -60 °C to 200 °C and have better purity than septa made of natural rubber, butyl or red rubber. However, they have less effective resealability properties and are therefore more suitable for single-injection applications....
Septa, 12 mm
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....
