General Information

Connection of tubing of the same diameter in areas of chemical and physical laboratory technology, biotechnology, medical engineering, nuclear technology.

For conveyance of ultrapure media and all kinds of aggressive and dangerous liquids and gases.

Solvent and chemically resistant, non-leachable tubing connections, non-slip fluted nozzles on both sides, construction in one piece without joints, mirror-smooth inner surfaces with low tendency to adhesion, made of application-oriented, sterilizable high-performance materials PTFE, PVDF or PP.

For elastic tubing with inside diameters of 4 to 12 mm.

PP (Polypropylene)

Extremely good impact toughness and notch impact strength

Higher hardness and stiffness as well as better resilience than PE

Thermoforming possible

Very good dielectrical properties

Good resistance to alcohols, ketones, conc. acids and alkalis

Not stable to aromatic hydrocarbons, fats and oils, halogenes

Autoclavable

Resistant to hydrolysis

Physiologically safe

Regulatory compliance to FDA 21 CFR 177.1520, RoHS, BPA-free, DEHP-free, BSE/ADI-free

Colour: grey

Density: 0.90 g/cm³

Temperature range: +5 to +90 °C

Shore hardness D: 72°

Max. operating pressure: 10 bar at +20 °C

Water absorption: <0.05 %

Tensile strength: 25 - 40 N/mm²

Elongation at break: 800 %

Surface resistance: >10¹³ Ohm

Melt flow index MFR: 0.3 g/10 min.

PVDF (Polyvinylidene fluoride)

High-quality technical plastic for chemical apparatus and machine building, especially in the petrochemical, metallurgical, pharmaceutical, food processing, paper and textile industry as well as in the nuclear technology.

High impact toughness even at low temperatures

Good breakdown strength

Low dielectric loss factor

Highest mechanical stability and stiffness

Meeting highest purity requirements

Comply with the guidelines from FDA and USP class VI, additionally PVDF has the KTW approval. Up to +150 °C it is non-toxic and since it has a similar property to glass it is a no-culture medium for microorganisms.

Can be treated by autoclave (absolute sterile) and sterilized with gamma-rays without losing its mechanical qualities

Outstanding resistance to UV, weather and aging

Flame-resistant

High thermal stability

Resistant to alcohols, fats and oils, halogenes, alkalis, acids

Not stable to aromatic hydrocarbons, ketones, amines, pyridine, dimethylformamide, hot alkalis, fuming sulfuric acid

PTFE (Polytetrafluoroethylene)

Heavy-duty plastic

Antiadhesive surface

Outstanding sliding properties

Lowest friction coefficient of all fluorinated plastics

Excellent stress cracking resistance

Excellent weather resistance

Highest gas-tightness

No water absorption

Very good dielectric properties independent of frequency and temperature

Very good electrical insulating capacity also at air humidity

High tracking resistance

Non-combustible
