Vials, Septa

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.

The septa made of butyl red/PTFE grey are temperature-resistant from -40 °C to 120 °C and have excellent chemical properties with regard to cleanliness.

On Pharma-Fix seals, it is only the butyl areas that can come into contact with the sample, are PTFE coated. The areas that abut the edges of the glass are not coated. This ensures a particularly good seal.

All well plates made of PP and sealmats are fully chromatography tested. There are several advantages compared to usual vials and caps. Furthermore, the SBS/ANSI footprint assures compatibility with all well plate capable prep stations and chromatography autosamplers.

Well plates and sealmats are suitable for polar and non-polar solvents, in case of very critical analysis and very low sample concentrations.

• Space saving on the lab bench and when stored
• Faster sample preparation when multichannel pipettes are used
• Time saving because many different samples are prepared on one single plate

The plates made of PP are non-coated, non-sterile and chromatography tested.

Glass coated well plates are available on request.

The LABSOLUTE® vials for optimised micro-sampling are the best solution for very small sample volumes. The universally usable, so called vase vials with a residual volume of max. 15 µl can be tighly closed with the suitable LABSOLUTE® caps. All the vials are made of clear or amber first hydrolytic class glass. Because of their wide base, the vials stand independent and safe in almost every autosampler.

Further vials with ND8 or ND10 screw neck are available on request.

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

The LABSOLUTE® kits ND13 contain shrink-wrapped screw vials ND13 made of clear or amber first hydrolytic class glass and corresponding screw caps made of PP.

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

Further kits are available on request.

The LABSOLUTE® kits ND11 contain shrink-wrapped snap ring vials ND11 made of clear or amber first hydrolytic class glass and corresponding snap caps made of PE with 6 mm centre hole.

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.

These septa made of red butyl and grey PTFE 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 50° shore A.
