Trace analysis tubes

SEPARA integrates in one single device auto-sampler vial, filtration membrane, plunger, and cap/septa. The single step filtering process is efficient and saves time. Fast and simple to use. Reducing sample loss. After filtration the sample is ready to use in most standard autosampler. The pre-slit cap ensures easy and clean transfer of sample. 5 different septa material, PP vial with Ø 12 x 33 mm, Filtering capacity 0.48 ml, dead volume <30 µl, maximum operating temperature 50 °C

Products made of PFA are chemically inert and highly suitable for applications requiring high purity, such as for environmental and trace analysis. They are heat resistant and have a non-stick, easy to clean surface. Due to the extremely hydrophobic, anti-adhesive and smooth surfaces, it has no carry-over, no cross contamination and no memory effects. High thermal stability from -200 °C to + 260 °C. Products made of PFA are ideal for storage of almost all corrosive chemicals, including hydrofluoric, nitric and perchloric acid.

Features

• Very low level of metal ions
• High mechanical strength and dimensional stability
• Can be used in the microwave
• Unbreakable, transparent
• Can be used for cryogenic applications down to -200 °C
• Heat resistant up to 260 °C

These unbreakable test tubes are excellent for trace metal analysis. They are inert, non-contaminating, and transparent for easy viewing of contents. They withstand temperature extremes. Can be sterilized repeatedly. Availlable with or without PTFE-stopper.

• Made from fluoropolymer PFA resin
• Low metal ion content
• Inert

Screw cap, jet and feed tube are one-piece moulded from ETFE. Ideal for contamination-free work and suitable for trace element analysis.

This ultra-shallow, concave dish is ideal for holding, weighing, crystallizing, evaporating and drying small samples of liquids, powders and solids. It can also be used as a convex cover for beakers and Erlenmeyer flasks to limit airborne contaminants, while still allowing gas exchange. All sizes are molded to the same contour for easy stacking. Shatter-proof PTFE material is chemical resistant and easy to clean.

• Inert, chemically resistant
• Smooth and unbreakable
• Use as beaker covers

These PFA graduated bottles have a convenient wide-mouth opening for easy filling and pouring. These unbreakable, chemically inert bottles can be used for storage of virtually all corrosive chemicals. PFA material is heat resistant, non-stick and easy-to-clean. Each includes a PFA cap with an inert fluoropolymer cap liner to ensure leak-proof sealing. Ideal for environmental sampling, or for storage in pharmaceutical and intermediate-stage semiconductor processing applications.

• Wide-mouth for easy filling
• Ultra pure and chemically inert
• Non-stick and easy-to-clean

Transparent, with tightly sealing screw closure (saw-tooth thread S and built-in sealing lip). Excellent resistance to temperature (from -200 to +250 °C). Ideal for long-term storage of high-purity oxidants, acids, alkalis, as well as hydrocarbons, trace analysis solvents and standards. Autoclavable at 121°C (2 bar) according to DIN EN 285.
