The Rare Gas Purifier is of a standard size (19) suitable for rack or bench mounting, and specifically made for laboratory or process work. The Rare Gas Purifier, has been developed from a family of rare gas purifiers originally designed by BOC. Depending on flow rate the RGP-4 in normal use is on average capable of continuous operation for in excess of two years before it becomes necessary to replace the reagent tubes. For normal flow rates of 10 litres/minute that will reduce the impurities (typically 30 vpm) of commercial rare gases (argon, helium, krypton, neon, and xenon) down to a level of less than 1 vpm in total.
Features:
Simple to operate, low cost, fully automatic, factory pre-set system
Rapid warm-up time
Excellent purification of commercial grade rare gases, impurities reduced to less than 1 vpm
Unaffected by ambient temperature variations
Lightweight, robust, compact, 19 rack mounting
Long life reagent tubes.
Stainless steel blade edge, cutting edge on one side, protected by detachable plastic cap.
Single use razor, plastic handle and head with single blade
Single use.
Non sterile.
Dimensions: head approximately 4cm, handle approximately 11cm.
The reactions of precipitation and color change are observed. 6 points, long 7.5cm, 5cm wide, used as a vessel for simultaneous simultaneous precipitation of small amounts of precipitation without reaction.

The consists of an inlet manifold, which supplies water to a central hub. The turbine is mounted on a horizontal shaft with a clear acrylic splash guard to enable maximum visibility of the workings. This pressure can be accurately controlled using the software supplied with the service unit. The unit incorporates a pressure sensor to measure the inlet condition of the water. Water exits the hub radially through two square orifices. The hub is connected to the manifold using a graphite face seal.
