CapTite Microfluidic Fittings, Components and Kits

Routing fluids can be one of the most agonizing and time-consuming tasks of microfluidic research. Poor world-to-chip hardware, bulky components, leaky seals, and dead volumes erode performance and reliability. Even simple capillary separations can require a full day's construction — not including the hours spent digging through catalogs for the right components.

Finally, however, there is a better option. LabSmith's new CapTite breadboard-based components and microminiature, high-performance connections take this pain out of microfluidic research, helping you to focus on gathering data rather than constructing your setups.

• Simple, compact components
• Fast, breadboard-based design
• Leak-free high pressure setups
• Complete building kit for 360 µm capillary tubing

High Performance Fittings and Fixtures

CapTite components give you everything you need to build, and re-build, microfluidic setups — all inter-compatible, all ready to use. Based on components developed by Sandia National Laboratories, these 360 µm microfluidic products include breadboards*, ferrules*, tees and crosses*, refillable cartridges, valves* and tools. Compact, simple components are thoughtfully designed for leak-free connectivity, even at high pressures.

Small Footprint Designs

The photos above shows the compact nature of CapTite components — a welcome relief from bulky, multi-piece fittings and components. Setups for simple tasks such as one-step separations can be built up in a fraction of the time and footprint of other fittings.

What's more, CapTite components enable build-up of complex setups that cannot be completed easily by other methods, including complete sample prep and analysis systems. You can also add bonded-port connections* to route fluids through and between chips securely: no more world-to-chip headaches!

Reusable Components

All CapTite components are designed for low dead volumes and easy cleaning, enabling long life over multiple runs. Complete construction kits are available, with everything you need to build up experiment after experiment, for great value with little waste.

Whether your application includes sample preparation, separations or other microfluidic setups, LabSmith's CapTite components will give you more than you've come to expect, at a fraction of the price of other components.

CapTite Microfluidic Fittings and Components

	Breadboard This Fiberglass breadboard enables rapid positioning and mounting of microfluidic components to create an endless array of reusable setups. Compatible with all LabSmith interconnect components, the breadboard features holes on 1/4-inch centers and includes standoffs, non-slip feet and mounting screws. Dimensions: 4 in W x 6 in L (102 mm W x 204 mm L).
	Ferrules and plugs These one-piece, compact (3 mm diameter) PEEK™ fittings connect 360 µm capillary tubing to all of our microfluidic components. Precision-manufactured seats provide high pressure seals to 5 kpsi finger-tight or 10 kpsi tool-tight, with no sleeves. Reliably seal hundreds of times, with easy clean-up and re-use. Ferrule diameter: 0.12 in (3 mm). Other materials available upon request.
	Tees, Crosses and Unions Ultem® interconnects enable fast, high pressure, multi-port interconnection. Precise mating of capillary tubes provides minimal dead volumes. Mounting holes allow easy positioning on breadboard. Dimensions: 0.4 in Wx 0.4 in L x 0.15 in H (10 mm H x 10 mm L x 4 mm H). Interfaces with ferrules and plugs.
	Valves This manually-controlled, 3-port selector valve provides fluid routing at pressures up to 10 kpsi. Knurled control knob and stable, high-cycle switching. Mounting holes for breadboard positioning. Dimensions: 0.5 in W x 0.5 in L x 1.25 in H (13 mm W x 13 mm L x 32 mm H) w/ mounting base (includes knob). Knob is 0.75 in (19 mm) diameter.
	Cartridges Micro-liter volume cartridges can be filled, and refilled, with many types of packing, for applications such as biomolecule concentration, reverse phase andion exchange. Easily disassembled and cleaned, the cartridges enable high-speed processing of small volumes (2ul-100ul) for high throughput sample preparation. Made of biocompatible PEEK. (Brochure)
	Bonded Port Connectors These Ultem® adapters bond directly to substrates or devices to accept ferrules to connect capillary tubing. Alignment shoulder provides easy, accurate interface to 1 mm chip port. Dimensions: 5 mm diam x 5 mm H. Guide to attaching bonded port connectors.
	Luer-Lock™ Adapter Provides reliable connection from standard Luer-Lock syringes and syringe pumps to capillary tubing. Interfaces with ferrules. Luer-Lock is 0.375 in (10 mm) outer diameter.
	Microfluidic Construction Kits Complete microfluidic construction kits, including breadboard, interconnects, tubing, syringe adapter, and more. Choose from Single User, Capillary Interface or Microfluidic Chip Interface kits. The best value for prototype and permanent construction of microfluidic setups.
	Installation Tools and Supplies Capillary tubing, assembly wrenches, fast-set epoxy and other supplies are available individually or as part of the Microfluidic Construction Kits.
