Antistatic Solutions for Laboratory and Chemical Engineering
Antistatic hoses hold an important position in the Reichelt Chemietechnik range. They are electrically conductive and therefore used in applications where static electricity can arise or electrical currents are handled. These systems find application in operational and industrial technology, chemical engineering, pharmaceutical technology, process engineering, and food technology.
Conductive Antistatic Hoses as Safety Solutions
Conductive antistatic hoses are considered safety tools. They are indispensable for conveying solid and liquid media, especially in explosion-protection areas where work may involve explosive atmospheres. The standard for electrically conductive designs is the discharge resistance, typically listed as <106 ohms.
Why Are Electrically Conductive Transport Hoses Necessary?
Electrostatic Discharge
To explain the necessity of antistatic hoses, it is essential to address electrostatic discharge. Many phenomena in everyday life are caused by static electricity, such as the occasional "shock" when touching a doorknob or the clinging of thin packaging films to the skin. While usually harmless in everyday situations, static electricity in laboratories and industrial environments can have serious consequences, ranging from damage to sensitive electronic components to fires or explosions. Under such conditions, suitable antistatic hoses and conductive connectors must be used.
Conductive pipes and tubing are necessary because static electricity can arise at all interfaces between solid and/or liquid phases, including during the transport of solid or liquid media through chargeable systems. Electrostatic charging is caused by the internal friction within the medium and its friction against the inner wall of the hose.
Antistatic Products in Explosion-Protection Areas
Conductive transport hoses are indispensable in "Ex" (explosion-protection) areas. In such zones, sparks must be avoided at all costs to prevent the ignition of explosive atmospheres or damage to sensitive components. Electrostatic discharge is one of the 13 possible ignition sources that can ignite explosive vapors, mists, dust, or other gas mixtures. Preventing this requires compliance with guidelines and regulations such as the ATEX directive.
Protective Measures in Hose Technology
The best protective measure to prevent sparks during the transport of solid or liquid media is to ensure that static electricity does not arise in the first place, by selecting the appropriate hose. Antistatic tubing immediately dissipates generated static electricity, preventing accumulation. However, proper grounding of the material and the use of suitable antistatic connectors are essential, as conductive designs alone are not sufficient.

The operating temperature range is -200°C to +250°C, the Shore hardness D is specified as 65° according to DIN 53505, and the burst pressure reaches up to 140 bar at +20°C, depending on the hose dimensions. Typical applications for this high-tech PTFE antistatic hose include the semiconductor industry, pharmaceutical technology, food production, process engineering, and other uses in explosion-protection areas ("Ex zones").
Antistatic PFA and PTFE Corrugated Tubes
Antistatic PFA and PTFE corrugated tubes, often marketed as "corrugated hoses," are distinguished by their excellent flexibility combined with high mechanical strength. Their design allows for very small bending radii (18 mm to 134 mm), even for larger nominal widths. The discharge resistance of these electrically conductive tubes is <106 ohms, achieved through carbon powder alloying of the plastics. Additionally, they exhibit outstanding temperature resistance: -270°C to +260°C for PFA variants and -200°C to +260°C for PTFE counterparts. The physiological safety of the materials and their very low gas permeability (superior gas tightness) enable the transport of ultra-pure gases and liquids, making them ideal for use in the pharmaceutical, medical, and food industries, as well as in other sensitive explosion-protection areas. In these settings, they are often used as antistatic exhaust or ventilation hoses to convey particularly hot or cold, and frequently chemically aggressive, gases.
PTFE antistatic corrugated tubes are also available with a smooth outer sheath. This electrically conductive version features an FDA-compliant inner corrugated tube, reinforced by an additional EPDM intermediate layer (electrically conductive) and an outer sheath. A high-temperature aramid braid serves as the pressure carrier. Despite the outer reinforcement, these conductive corrugated tubes maintain excellent flexibility, with bending radii between 40 mm and 100 mm. The multilayer antistatic design, with a discharge resistance of <109 ohms, operates in a temperature range of -20°C to +150°C, with short-term tolerance of up to +180°C for 30 minutes. Additional notable features include pressure resistance up to 16 bar and vacuum resistance up to 0.9 bar at +20°C.
Antistatic Compound and Double-Walled Hoses Made of PTFE and FEP
The antistatic compound and double-walled hoses made of PTFE and FEP, including the PTFE suction and pressure hose and the FEP Antista double-walled pharmaceutical suction and pressure hose, hold a special position.

The inner surface is physiologically safe, free of extractable components, and compliant with various relevant standards (FDA-compliant, BfR-compliant, KTW-approved, USP Class VI-compliant). This makes these hoses suitable for sensitive applications, such as in the food and pharmaceutical industries.
The low discharge resistance of <106 ohms also allows for use in explosion-protection areas (Ex zones 0 and 1). The multilayer construction, optionally featuring an additional steel wire spiral, ensures high pressure resistance up to 16 bar and vacuum resistance up to 900 mbar at +20°C, while maintaining small bending radii of 100 mm to 300 mm, depending on the hose design. The fluoropolymer inner lining provides excellent chemical resistance and exceptional temperature durability, ranging from -30°C to +150°C (with saturated steam tolerable up to +150°C for a maximum of 30 minutes, e.g., during cleaning). These electrically conductive double-walled hoses are true "all-rounders," capable of being used in a wide range of applications.
Transparent Antistatic Hoses
For many applications, a transparent antistatic hose is advantageous, as it allows visual monitoring of the medium being conveyed. The conductive PFA Antista chemical hose combines this feature with the benefits of fluoropolymers. The operating temperature range is -200°C to +250°C, and the working pressure varies between 27 bar and 57 bar at +20°C, depending on the hose dimensions. The conveyed media only come into contact with physiologically safe, FDA-compliant PFA. Conductive black strands (discharge resistance <106 ohms) run longitudinally on the outer surface, making these hoses ideal for transporting alcohols, fuels, highly flammable solvents, and aggressive chemicals in explosion-prone areas.
PE Double-Walled Hoses
Ultra-high molecular weight polyethylene (UHMW-PE) is another polymer used to produce antistatic hoses. UHMW-PE Antista double-walled chemical hoses are suction and pressure hoses with excellent chemical resistance to most acids, alkalis, and solvents. These conductive double-walled hoses are flame-retardant, abrasion-resistant, and resistant to weather, aging, and ozone. The multi-layer construction includes a polyethylene inner lining, a polyester fabric insert with an additional steel wire spiral and cross-linked copper strands, and an EPDM outer sheath, ensuring high mechanical stability and a pressure capacity of up to 16 bar at +20°C. The discharge resistance is <106 ohms, and the temperature range is -35°C to +90°C.
PA Antistatic Hoses
Polyamide 12 (PA 12, Poly-Laurylactam) is a thermoplastic, semi-crystalline homopolymer made from a single monomer component. It is used for precision hoses and tubes, particularly for pressure-resistant and impact-resistant fuel lines, transport and antistatic hoses. PA 12 offers excellent resistance to fuels, lubricants, aliphatic hydrocarbons, oils, greases, ketones, alcohols, cyclic and aromatic hydrocarbons, halogenated solvents, steam, X-rays, and UV radiation.
PA Chemical Hoses (Electrically Conductive): These antistatic vacuum and pneumatic hoses are used in explosion-protection zones. The antistatic property is achieved by filling the material with graphite, resulting in a discharge resistance of <106 ohms. These tubes are abrasion-resistant, wear-resistant, and dimensionally stable. The temperature range is -40°C to +90°C, and the pressure resistance ranges from 12 bar to 45 bar at +20°C, depending on the hose dimensions.

The multilayer construction, optionally featuring an additional steel wire spiral, ensures high pressure resistance up to 16 bar and vacuum resistance up to 900 mbar at +20°C, while maintaining small bending radii of 100 mm to 300 mm, depending on the hose design. The fluoropolymer inner lining provides excellent chemical resistance and exceptional temperature durability, ranging from -30°C to +150°C (with saturated steam tolerable up to +150°C for a maximum of 30 minutes, e.g., during cleaning). These electrically conductive double-walled hoses are true "all-rounders," capable of being used in a wide range of applications.
Transparent Antistatic Hoses
For many applications, a transparent antistatic hose is advantageous, as it allows visual monitoring of the medium being conveyed. The conductive PFA Antista chemical hose combines this feature with the benefits of fluoropolymers. The operating temperature range is -200°C to +250°C, and the working pressure varies between 27 bar and 57 bar at +20°C, depending on the hose dimensions. The conveyed media only come into contact with physiologically safe, FDA-compliant PFA. Conductive black strands (discharge resistance <106 ohms) run longitudinally on the outer surface, making these hoses ideal for transporting alcohols, fuels, highly flammable solvents, and aggressive chemicals in explosion-prone areas.
PE Double-Walled Hoses
Ultra-high molecular weight polyethylene (UHMW-PE) is another polymer used to produce antistatic hoses. UHMW-PE Antista double-walled chemical hoses are suction and pressure hoses with excellent chemical resistance to most acids, alkalis, and solvents. These conductive double-walled hoses are flame-retardant, abrasion-resistant, and resistant to weather, aging, and ozone. The multi-layer construction includes a polyethylene inner lining, a polyester fabric insert with an additional steel wire spiral and cross-linked copper strands, and an EPDM outer sheath, ensuring high mechanical stability and a pressure capacity of up to 16 bar at +20°C. The discharge resistance is <106 ohms, and the temperature range is -35°C to +90°C.
PA Antistatic Hoses
Polyamide 12 (PA 12, Poly-Laurylactam) is a thermoplastic, semi-crystalline homopolymer made from a single monomer component. It is used for precision hoses and tubes, particularly for pressure-resistant and impact-resistant fuel lines, transport and antistatic hoses. PA 12 offers excellent resistance to fuels, lubricants, aliphatic hydrocarbons, oils, greases, ketones, alcohols, cyclic and aromatic hydrocarbons, halogenated solvents, steam, X-rays, and UV radiation.
PA Chemical Hoses (Electrically Conductive): These antistatic vacuum and pneumatic hoses are used in explosion-protection zones. The antistatic property is achieved by filling the material with graphite, resulting in a discharge resistance of <106 ohms. These tubes are abrasion-resistant, wear-resistant, and dimensionally stable. The temperature range is -40°C to +90°C, and the pressure resistance ranges from 12 bar to 45 bar at +20°C, depending on the hose dimensions.
