Announcing Arcmed

Diba and Bio-Chem have merged and rebranded to form a simplified fluid handling supplier dedicated to helping engineers, scientists, and doctors solve the toughest diagnostic and analytical challenges.

Connection Systems

Our fittings, connectors, adapters, and tubing — simplified into compatible platforms.

Fluid Transfer Simplified

Experience our innovative connection components grouped into a variety of assembly systems that ensure you achieve low carryover fluid transfer in your application.

Flare System

Flare Design

Typical thermoforming creates scoring and distortion of tubing that give particulates more surface to cling to, producing sample carryover. Our proprietary thermoforming process creates an inert, smooth surface with a flat-bottom, face seal.

Flare System

Flare Applications

  • For precision fluid lines, such as those that handle samples and reagents
  • To reduce build and service times using pre-assembly and labeled tubing services
  • Maximum chemical compatibility and minimal carryover
Flare System

Flare Compatibility

When combined with our Click-N-Seal fittings, the flared tubing connection system produces a leak-free seal with only tube material in the fluid path. Flared tubing assemblies are available in a variety of configurations to adapt to your instrument.

  • 1/16 - 1/8” OD plastic tubing such as PTFE, FEP, LDPE, or PEEK
  • Connections to 1/4-28, 10-32, M6, and 6-40 threaded ports
  • Click-N-Seal Fittings:
    • Standard: A recessed design for maximum engagement with threaded ports
    • Plus: A slim profile with improved pressure and chemical compatibility
    • Ultra: A compact head design with pressure compatibility up to 7,000 psi for HPLC applications

Type P Connection System

TypeP-2
TypeP-1
TypeP-3
Type P

Type P Design

The Type P flangeless tube connection system incorporates a PTFE seal housed in a 316 stainless steel case. The Type P fitting system uses a one-piece ferrule, which fits permanently to the outside of the semirigid tubing.

Type P

Type P Applications

  • High purity, high chemical resistance, low dead volume, repeat connection and disconnection
  • Shallow depth and PTFE ports
Type P

Type P Compatibility

  • 1/16”, 3/16”, or  1/8” OD semi-rigid tubing
  • Connections to 1/4”-28 UNF, M6, or 5/16”-24 UNF threaded flat-bottom ports
  • Pressure rated up to 1,000 psi (69 bar)
  • Type-P Ferrules
  • Click-N-Seal Fittings
    • Standard: A recessed design for maximum engagement with threaded ports
    • Plus: A slim profile with improved pressure and chemical compatibility
    • Ultra: A compact head design with pressure compatibility up to 7,000 psi for HPLC applications
  • Omni-Lok Fittings
    • Headless: Slim profile design with pressure compatibility up to 2,000 (7,000 psi) for HPLC applications
    • Wide Head: Flangeless, easy-grip design
    • Long Head: Extended design for easier installation in tight spaces

Type S

TypeS-1
TypeS-2
TypeS-3
TypeS-4
Type S

Type S Design

The Type S fitting system uses a two-piece ferrule that fits permanently to the outside of the tubing. Two-part ferrules consist of an inner PEEK sealing surface and a stainless steel lock ring, with only the inner portion in the fluid path.

Type S

Type S Applications

  • For applications that require high pressure and low dead volume
  • Repeated connection and disconnection
  • Microfluidic applications
Type S

Type S Compatibility

  • Pressure rated up to 500 psi (2,500?)
  • 1/16”, 1/8”, or 3/16” OD semi-rigid tubing
  • Connections to 1/4”-28 UNF, M6, 5/16”-24 UNF, or 10-32 threaded, flat-bottom ports and taper/flat-bottom 6-40 threaded ports
  • Type-S Ferrules
  • Click-N-Seal Fittings
    • Standard: A recessed design for maximum engagement with threaded ports
    • Plus: A slim profile with improved pressure and chemical compatibility
    • Ultra: A compact head design with pressure compatibility up to 7,000 psi for HPLC applications
    • Micro: Our smallest design built specifically for microfluidic applications 
  • Omni-Lok Fittings
    • Headless: Slim profile design with pressure compatibility up to 2,000 (7,000 psi) for HPLC applications

Gripper

Gripper Design

Gripper connection systems use a one-piece ferrule that fits permanently onto the outside of semirigid tubing. Ferrules have an outer stainless steel or PEEK casing and inner PTFE sealing face, ensuring that only PTFE is in the fluid path.

Gripper Applications

  • For high chemical resistance and repeated connections
  • For high temperatures

Inverted Cone

Inverted Cone Design

Inverted cones provide a reuseable, nonpermanent low-pressure connection with only the ETFE cone in the fluid path. A recess in the fitting houses the inverted cone, allowing maximum thread engagement with the port

Inverted Cone

Inverted Cone Applications

  • Ensure the system stays sealed even in shallow PTFE ports
  • For economic, faster, and convenient assembly and disassembly without tools
  • Low pressure
Inverted Cone
