GENERAL USE INLET SOLVENT FILTERS - Large Surface Areas - Disposable - 2µm, 10µm, and 20µm Filters Available - General Use and Prep Filters for Higher Flow Applications

It is good practice to filter your solvents to prevent pump damage. Upchurch Scientific® 316 stainless steel filters provide that protection. Their large surface areas mean longer life without pump cavitation. Because filters should be changed periodically, we make it easy to replace them without tools. For those filters using a plastic nut, thread the nut into the filter and finger tighten. Our other filters have stems, allowing easy insertion directly into your inlet tubing. The filters with stems are 100% 316 stainless steel. Filters with threaded fittings have threaded Kel-F® (PCTFE) caps. Please Note: the internal design of the A-309 and the A-230A Filters allows solvent to be drawn to within approximately 1/8" of the bottom of your solvent bottle.

HPLC VACUUM DEGASSING SYSTEMS - High Efficiency Degassing / Continuous Monitoring for Leaks and Errors / Smallest Footprint Available / Quiet, Long-Life Operation / Two and Four Channel Models
Designed for HPLC Rheodyne® HPLC Vacuum Degassing Systems are high-efficiency inline modules that quickly and conveniently remove dissolved gasses from HPLC mobile phases. The unique design of the modules assures reliable continuous operation and the highest level of continuous performance available, thus eliminating the need for helium degassing. Depending on the model, two to four solvent lines may be degassed simultaneously by one unit. Compared to PTFE degassing, the extremely low internal volume of the module's analytical-scale Teflon® AF channels provides quicker equilibration and shorter startup times.
Degassing Chamber and Membrane The heart of Rheodyne's Vacuum Degassing System is the Teflon AF degassing membrane. Within each vacuum chamber, there is a single, highly efficient and chemically inert hollow tube, which operably removes dissolved gas from the flowing mobile phase stream. As the HPLC mobile phase passes through the Teflon AF tubing, dissolved gas migrates under a concentration gradient through the fluid and tubing into the vacuum where it is exhausted to the atmosphere. Teflon AF degassers are a low flow restriction alternative to PTFE degassers.
Unique Vacuum Pump Rheodyne HPLC Degassing Systems utilize a two-stage, series, stepper motor driven vacuum pump with a unitary PTFE diaphragm designed specifically for the rigors of HPLC degassing. On power up, each model self-tests and validates its vacuum sensor. The pump runs continuously and is whisper quiet. The vacuum system is continuously vented.
Ten Year Life The life expectancy of the vacuum pump is greater than 220 million cycles, or typically 10 years of average use.
Constant Vacuum Level System Condition Responsive - Closed loop electronic control continuously monitors the system for faults and varies the vacuum pump speed (RPM) to quickly evacuate the vacuum chambers and sustain a constant vacuum level for optimal degassing conditions.
Rapid Equilibration Time The "Ready-to-Run" degassing system equilibration time is three minutes or less.
Easy to Prime These units are easy to prime due to their low flow resistance and ultra-low internal volumes.
Clean Detector Baselines Absolute zero vacuum hysteresis means clean detector baselines.
Validation Output A 2-pin rear panel receptacle labeled "Validation" with mating screw-lock plug is provided to allow a validation signal from the control circuit to be sent to a computer or data system. This validation output indicates vacuum level.

BOTTLE CAPS - Inexpensive / Extremely Simple - No Threaded Ports or Fittings!

If you are looking for a bottle cap that is quick and easy to use, but still allows many connection options, we have just what you need! Upchurch Scientific® injection-molded caps are manufactured of inert Tefzel® and polypropylene. They fit standard GL-45 or smaller-neck GL-38 glass bottles.Each cap has three holes. With two of the holes you simply push your tubing straight through. The third hole, with a luer taper, can be used for a number of options. Any male luer will fit snugly in this hole, or you can use our A-626 or A-627 Plug. Exceptions are the A-610 and A-610B Bottle Caps. Please see the note below right.To ensure a tight seal, use Upchurch Scientific Teflon® tubing with these bottle caps.

BOTTLE CAP PLUGS AND ADAPTERS
Use our A-626 Bottle Cap Plug to seal the third "tapered" luer hole found in most Upchurch Scientific bottle caps. Or, use our A-628 Plug to seal any unused 1/16" or 1/8" bottle cap holes.
Alternatively, try our A-627 or A-629 Filter Bottle Cap Plug for an extra cap hole. The 20µm stainless steel frit in these products prevents foreign matter from contaminating your solvent while leaving the bottle open to the atmosphere, thus allowing fluid to be pulled out without creating a vacuum (generally not used with sparging applications). All plug bodies are manufactured from ultrahigh molecular weight polyethylene (UHMWPE).
Our P-600 Bottle Cap Adapter is designed to allow use of 1/32" OD tubing with our caps. Just insert the Adapter into a tubing cap hole, then connect your 1/32" OD tubing with our F-126S or F-126H MicroTight® Fitting.

PRECOLUMN FILTERS - 0.5µm or 2µm Porosity Frits Available / Great Column Protection / Stainless Steel and Biocompatible PEEK™ Polymer Versions Available				INLINE SOLVENT FILTERS - Excellent for General Purpose Inline Use / 2µm and 20µm Porosity Frits Available
Upchurch Scientific® Precolumn Filters have .020" diameter thru-holes and 8° distribution cones for minimal band spreading and mixing. They are available in stainless steel (A-315/A-316), pressure rated to 9,000 psi (620 bar) and biocompatible PEEK polymer versions (A-355/A-356), pressure rated to 5,000 psi (345 bar). Choose either the 0.5µm or 2µm version to filter particulates from your flow path.				Placed between the pump and sample injection valve, our Inline Solvent Filters trap particles released through normal piston seal wear. Without an inline filter, these particles can be flushed through your system's tubing to the sample injection valve, resulting in valve damage and further system contamination. These filters are pressure rated to 8,500 psi (586 bar) and use a 2µm or 20µm stainless steel frit. An 8° distribution cone helps spread the flow of the mobile phase over the entire surface of the frit, while the .050" diameter thru-hole allows unrestricted solvent flow.
