RheBuild Kits containing genuine Rheodyne parts are available for all Rheodyne products. Included in each RheBuild Kit are all the parts, tools, and instructions to maintain the precision performance of Rheodyne stainless steel and PEEK platforms.

RheBuild Kits are convenient and eliminate the need to order individual parts.

Rheodyne stainless steel and PEEK sample loops are factory-cut and finished to the highest quality. The 316 stainless steel loop ends have a square cut and are burr-free, offering a flush connection to the valve. The flexible PEEK loop ends are provided with a clean and straight cut for easy installation onto the valve.

Stainless steel sample loops are supplied with unswaged fittings. The two ends of the loop must be completely bottomed in the injector ports before the ferrule is swaged onto the loop. Swaging each end separately and then replacing the ends in their respective ports of the same valve ensure that the loop ends are bottomed into the ports. A fitting made up in one port may leave an undesirable cavity in another port. As all ports vary in all valves, careful attention to loop installation is important.

PEEK loops are also supplied with unswaged RheFlex® fittings but do not require the same swaging precaution. The fittings can reposition along the loop tubing when the fitting reinserts in the ports for correct loop installation.

Genuine RheFlex fittings have evolved as the quality fitting required for use with Rheodyne valves. Specially designed to meet the rigid requirements necessary to match Rheodyne valves, RheFlex fittings offer precision and quality that can also be used in common laboratory applications that require precise liquid connections. Rheodyne combines the unique RheFlex ChromTRAC colour-coding fitting knobs with RheFlex fittings sets for a value-added fittings identification system. ChromTRAC knobs and mapping on valves are the industry standard for tracking inlets and outlets of system components.

The RheFlex family includes Rheodyne's classic stainless steel multiple length nut and ferrule systems, which have been the standard for valve connections for a quarter of a century, to the more recently introduced RheFlex TF, "Twist Free" technology.

Rheodyne manual sample injectors are available for micro, analytical, and preparative scale analysis. Sample injectors are grouped depending on the sample volume to be loaded onto the column:

Scale Sample Volume

* Micro: 2 µL to 500 µL
* Analytical: 1.0 µL to 5.0 mL
* Preparative: 100 µL to 10 mL

Types and Capabilities
Dual Mode: Dual mode injectors (models ending in -25), also termed front loading injectors, can use both the partial-filling and complete-filling method for loading the sample loop. They are variable volume injectors because they allow the loading of various sample volumes.

Single Mode: Single mode injectors (models ending in "-10") use only the complete-filling method for loading the sample. The sample loop size determines the volume to be injected onto the column.

Rheodyne offers high-pressure manual switching valves to simplify your laboratory procedures and to improve the speed, resolution, and sensitivity of HPLC analysis.

Models include a variety of two-position platforms in six-port, seven-port, and ten-port flow architectures. Ports come in standard bore 1/16" and large bore 1/8" sizes. Stator materials include both 316 stainless steel and PEEK.

Rheodyne rotor seals are the polymeric disc that creates a high pressure seal against the stator. The seal wears with use, and is one of the only parts that may need routine replacement. Stators need replacing only if the ports become damaged.

Vespel blend rotor seals have an operating pH range from 0 to 10. Tefzel blend and PEEK blend rotor seals have a pH range from 0 to 14. Strong oxidizing acids such as concentrated nitric and sulfuric are not compatible with PEEK.
