Manufacturer: Starna Cells, Inc Brand: Starna Model: 20/O-Q-0.1

The Type 20 cell is designed for use in applications where a short path length and large window surface area is needed. This cell design is especially useful for opaque or viscose solutions. The cell consists of one fully fused component combining one window and the sides of the cell which forms the path length. The other window is separate and the cell can therefore be taken apart for cleaning. The cell wall and the removable window are polished so flat that the two will form a seal when placed in contact. Viscous and aqueous samples will allow the best seal to be formed, organic solvents will creep into the seal area for a less reliable seal. Type 20/O is open at one end similar to a Standard cell, unlike the Type 20/C which is completely enclosed when the window is in place. It is recommended that the cell holder Type CH-2049, shown below, is used with these cells to keep the cell together while standing in the instrument cell holder.

Manufacturer: COLE-PARMER Brand: Cole-Parmer

These variable-area flowmeters are offered with direct reading scales for water, argon, oxygen, carbon dioxide, nitrogen or helium. Multi-turn valve is included, and dual scales display flow rates in both metric and English units. Optional scales can be developed for diverse flow conditions facilitating OEM applications. Flowmeters are configured for in-line 3/4" NPT(F) connections. Scales can be purchased and interchanged. To change the scales, simply remove two small screws on front plate of meter and remove the plastic cover, and replace scale with desired scale, and replace cover and screws. For more details, contact an Applications Specialist. Durable valve allows for easy control of your media Yellow colored backing enhances readability and minimizes eye fatigue

All flowmeters come with correlation data sheets for water and air at standard temperature and pressure (STP). We can also supply calibration data for oxygen, nitrogen, hydrogen, helium, CO2, argon, other liquids and gases, and for conditions other than STP-call our Application Specialists for more information. Compact size makes these ideal for tight measuring areas Clear polycarbonate front shield magnifies scale 16%. A vertical tangential locator line ensures hairline accuracy in reading float position. Each flowmeter consists of a heavy-walled glass flowtube mounted in an anodized aluminum frame with white acrylic back plate (1/8' thick). Minimum flow rate is less than one tenth of the maximum flow value in the ordering table. Select a flowmeter with a high-precision valve for superior flow rate control-ideal for low-flow applications or for any application where you need precise flow control. The 16-turn high-precision valve features a nonrising stem to more accurately hit your desired set point.
