MarvelXACT UHPLC Connection Systems

Idex MarvelXACT UHPLC Connection Systems

IDEX MarvelXACT UHPLC Connection Systems deliver precision, repeatability, and ease-of-use for modern ultra-high-pressure liquid chromatography workflows. Designed to eliminate the risk of under- or over-tightening, MarvelXACT fittings feature a patented torque-limiting mechanism that provides a tactile “click” once optimal torque is reached—ensuring perfect installation every time.

Built on MarvelX™ face-sealing technology, these systems seal directly at the bottom of the port, creating true zero-dead-volume connections. This minimizes carryover, peak tailing, and band broadening for maximum chromatographic performance. All MarvelXACT systems are finger-tight to 19,000 psi, support 100+ connect/disconnect cycles, and use flexible 1/32" OD tubing for easy routing through UHPLC instruments.

  • Torque-limiting mechanism prevents under- or over-tightening
  • Face-sealing design eliminates dead volume
  • Finger-tight performance up to 19,000 psi
  • 100+ connection cycles without loss of performance
  • Compatible with standard 10-32 coned receiving ports
  • Available in stainless steel and bioinert flow path options

MarvelXACT Stainless Steel UHPLC Connection Systems

MarvelXACT Stainless Steel UHPLC systems provide rugged, high-pressure performance for demanding analytical applications. The patented torque-limiting fitting produces a distinct haptic “click” when optimal torque is achieved, removing guesswork from installation. MarvelX face-sealing technology ensures port-bottom sealing to eliminate internal volume and reduce carryover, peak tailing, and band broadening.

Featuring flexible 1/32" OD tubing for clean instrument routing, these systems are absolutely finger-tight and compatible with standard 10-32 coned ports. Each connection can be made and remade over 100 times without degradation.

MarvelXACT PEEK-Lined Stainless Steel UHPLC Connection Systems

MarvelXACT PEEK-lined systems combine stainless steel durability with a bioinert PEEK flow path for chemically sensitive applications. The torque-limiting mechanism provides consistent installation force, confirmed by tactile click feedback, while MarvelX sealing technology creates true zero-dead-volume connections at the port face.

These systems use flexible 1/32" OD tubing, connect to 10-32 coned ports, and support over 100 connection cycles—all without tools. Ideal for biopharmaceutical and trace-analysis workflows where chemical compatibility is critical.

MarvelXACT PEEKsil UHPLC Connection Systems

MarvelXACT PEEKsil systems offer a fully bioinert flow path using PEEKsil capillary tubing, making them ideal for high-sensitivity and biomolecule applications. The patented torque-limiting fitting ensures precise tightening with a haptic click at optimal torque, eliminating user variability.

With MarvelX face-sealing technology, flexible 1/32" OD tubing, and compatibility with 10-32 coned ports, PEEKsil systems deliver zero-dead-volume performance and consistent sealing through 100+ connection cycles—completely finger-tight.

Key Definitions
MarvelXACT™ Connection System
An IDEX UHPLC connection system that combines torque-limited fingertight installation with MarvelX face-sealing technology to ensure consistent, zero-dead-volume connections.
Torque-Limiting Mechanism
A patented fitting feature that delivers tactile “click” feedback when optimal torque is reached, preventing under-tightening or over-tightening during installation.
Face Sealing
A sealing method where the fitting seals directly at the bottom of the receiving port, eliminating internal dead volume and improving chromatographic performance.
Zero Dead Volume (ZDV)
A connection characteristic indicating no excess internal volume at the fitting interface, reducing carryover, peak tailing, and band broadening in UHPLC systems.
PEEK-Lined Flow Path
A bioinert internal tubing configuration where stainless steel fittings are lined with PEEK, providing chemical resistance for sensitive or biopharmaceutical applications.
PEEKsil Tubing
A hybrid capillary tubing consisting of a fused silica core with a PEEK outer coating, offering bioinert performance with enhanced flexibility for UHPLC routing.
Frequently Asked Questions
What makes MarvelXACT different from standard fingertight fittings?
MarvelXACT uses a patented torque-limiting mechanism that “clicks” at the optimal tightening point, eliminating guesswork and ensuring consistent, leak-free connections every time.
Do MarvelXACT fittings require tools?
No. MarvelXACT fittings are completely fingertight and require no wrenches or torque tools, even at pressures up to 19,000 psi.
How many times can MarvelXACT fittings be reused?
MarvelXACT connection systems are designed for more than 100 connect-and-disconnect cycles without loss of sealing performance.
What port types are MarvelXACT fittings compatible with?
MarvelXACT systems are compatible with standard 10-32 coned receiving ports commonly used in UHPLC and HPLC instrumentation.
What material options are available?
MarvelXACT is available in stainless steel, PEEK-lined stainless steel for bioinert workflows, and PEEKsil tubing options for maximum chemical compatibility.
Can MarvelXACT help reduce peak tailing and carryover?
Yes. The MarvelX face-sealing design eliminates dead volume at the port interface, helping minimize peak broadening, tailing, and sample carryover.
