Just what you need to automate HPLC. Inject samples. Switch columns. Select solvents. All automatically with Rheodyne valves. Rheodyne's pneumatically-actuated valves enable you to introduce automatic stream control anywhere in your HPLC system. They work at pressures up to 7000 psi — offering many opportunities to save time and increase precision through automation. Automatic sample injection. Done with Rheodyne Model 7010A, a pneumaticallyactuated version of our popular loop-type injector. Excellent for use with an autosampler in routine analysis. Very helpful for inject ing the same sample repeatedly in methods development. Removable sample loops in eight sizes from 10 μΙ to 2 ml insure that successive samples will be exactly the same volume. Automatic column switching. Our 7000
Series valves will switch columns in and out of the stream to increase the speed of analysis. For example, two columns can be interfaced to analyze complex samples without employing gradient elution. Or a small column can be used to enrich and pre-fractionate a sample before switching the stream to an analytical column.
The following courses are being held in conjunction with EXPOCHEM '80 on Oct. 4-5 in the Houston Astrohall.

Automatic solvent selection. With Rheodyne's 5012A all-Teflon 6-position valve you can select any of six different solvents during automated methods development. Or automate many stepwise elution schemes of your own design.

Micro-Line contains no additives to migrate or contaminate media; and unlike PVC, it is plasticizer-free. It's crosslinked by a special process for memory thermal stability and biological compatibility. It displays excellent resistance to most lab chemicals—even many solvents. It can be autoclaved or sterilized with dry heat or ethylene oxide. It keeps its clarity and flexibility indefinitely—will not stress-crack. Micro-Line is easily custom-formed, tapered and connected to make a limitless variety of special appliances. Look at all the advantages of this versatile tubing: • Implantable and ideal for injections. • Non-kinking, softer and more economical than fluoroplastics (PTFE, FEP, etc.). • Less resistance to flow when bent to sharp angles.
• Easily fabricated into a coil to minimize tension on animals and pull-out. • Clearer and more pliable than PE. • Longer shelf life than PVC. • Diameter can be reduced up to 40% by cold-stretching to fit several needle sizes. • Heating resizes it for a firm connection. • Retains heat-formed shape. • Non-hemolytic, non-pyrogenic— virtually "biologically inert." • Conforms to Pharmacopeia XIX, Class VI, and National Formulary specs for injectable containers. Micro-Line is available in eight sizes: .010" to .050" ID. The five most frequently used sizes are packaged in a lab kit with spools of 100 feet of each. Kits are. available from your local distributor, or call or write:
