Trace analysis tubes
Gas washing columns, FEP/PTFE
PTFE top with two threaded connections. The standard PTFE frit has a pore size of approx. 3 µm and is screwed on the riser tube with an M8x1 thread. It can be exchanged with the PTFE gas distributor with fine bores which needs a lower primary pressure.
- Temperature resistance: from -200°C to 250°C
- Transparent
- Unbreakable
- Frit easily exchangeable
Griffin beakers, PFA
Transparent. With a raised scale. Excellent chemical resistance and very high thermal stability from -200°C to +260°C
Autoclavable at 121°C (2 bar) according to DIN EN 285.
The advantages of PFA
- Specially suitable for use in trace analysis
- Ideal for sensitive and valuable samples
- Long-term maintenance of low-concentration reference materials in PFA containers
- No memory effects
- Practically no carryover, no contamination due to the extremely hydrophobic, anti-adhesive and smooth surfaces
- Chemical inertness against nearly all chemicals
- Good transparency and dimensional stability
- Easy to clean
- Use of high purity raw materials
Narrow-mouth bottles with cap, PFA
These unbreakable PFA bottles can be used for storage of virtually all corrosive chemicals, including hydrofluoric, nitric, and perchloric acids. PFA bottles are chemically inert, heat resistant with a non-stick, easy-to clean surface and are ideal for environmental sampling. The inert fluoropolymer cap liner ensures leak-proof sealing. Supplied with PFA caps....
Petri Dish, PFA
The non-stick, chemically inert surface of PFA petri dishes is non-contaminating and ideal for high-purity biological applications that range in temperature from -200°C to 260°C. Each petri dish is shallow, cylindrical and translucent with a flat bottom that allows for easy observation and uniform specimen growth. Ideal for cell culture or drying applications. Stackable one-piece design does not require a separate lid. Can be autoclaved for repeat use....
Round-bottom flasks, PFA
Transparent, neck with NS 29/32. Suitable as safety flask for use with rotary evaporators to collect the distilled off liquid. High thermal stability and chemical resistance.
The advantages of PFA:
- Especially suitable for use in trace analysis
- Long-term maintenance of low-concentration reference materials in PFA containers
- No memory effects
- Practically no carryover, no cross-contamination due to the extremely hydrophobic, anti-adhesive and smooth surfaces
- High thermal stability, from -200 °C to +260 °C, autoclavable.
- Chemical inertness against nearly all chemicals
- Good transparency and dimensional stability
- Easy to clean
- Use of high purity raw materials
Sample jars with screw cap, PFA
With screw cap made of PFA. Cylindrical, tall shape.
Ideal for sample collection, transport and storage of samples.
The advantages of PFA
- Specially suitable for use in trace analysis
- Ideal for sensitive and valuable samples
- Long-term maintenance of low-concentration reference materials in PFA containers

- High thermal stability from -200°C to +260°C, autoclavable at 121°C (2 bar) according to DIN EN 285
- Chemical inertness against nearly all chemicals
- Good transparency and dimensional stability
- Easy to clean
- Use of high purity raw material
Sample vials, PFA
Sample vials made of PFA with conical interior and raised graduation (5 ml subdivisions).
Available in two different types, depending on application:
- Cored outside bottom
- Flat surface on bottom of vial for improved heat transfer (Recommended for use with hot plates
