Glass apparatus drawing

This glass apparatus is inexpensive and consists of a bottle having an internal sampling tube and calibrated sampling volume (5 ml). One draws a sample and then expels it into an external 5 ml beaker. 

Fig. 3.4 A. Laboratory scale 10-L sprouting equipment. The apparatus is made from glass. Oilseed rape sprouts have been grown for three days under continuous aeration. The sprouting medium is tap water. B. A schematic drawing of the major parts of the apparatus.

The MSWI bottom ash was successfully used, either vitrified alone (S10 100 wt% of bottom ash) or with addition of 90 wt% (SI) and 50 wt% (S5) of glass cullet, and drawn into fibres using a Pt/Rh monofilament drawing apparatus (Scarinci et al. 2000). The choice of these glass compositions was based on their... 

Purification of Water from Substances Dissolved in It. Assemble an apparatus as shown in Fig. 32. Fill cooler 2 with water. Feed the water upward through the cooler (why ). Prepare (draw out) 8-10 glass capillaries 10-12 mm long and seal them at one end. 

Fig. 9.13. Stock-type melting-point apparatus. A, tube B, magnetic core C, glass cross resting on the bottom (left drawing), poised above the ring of frozen solid (right drawing) D, lip of plunger which is observed E, hand magnet used to raise plunger.

Figure 3-27 Schematic drawing of matrix-isolation apparatus for resonance Raman measurements. 1, glass envelope 2, aluminum sleeve 3, refrigerator 4, gas line 5, steel screen 6, cold tip 7, aluminum radiation shield 8, Pyrex cup 9, spectroscopic-grade spark graphite rod 10, Pyrex capillary tube with sample 11, small mirror 12, cylindrical lens 13, collecting lens. 5 is placed to prevent sample deposition in the optical path. It must be removed from the path by using an external magnet once sample deposition on 6 is completed.

A cutaway drawing of the rotating-cylinder reactor is shown in Fig. 35. The mechanical aspects of the reactor system were designed to provide temperature control, fluid containment, and process measurements. The apparatus consists of a stainless steel (SS) holder and glass cylinder in which rides an SS piston, sealed by two Viton O-rings. Piston movements is monitored by a linear variable differential transformer (type 250 HCD, Schaevetz Engineering) attached to the piston and fixed relative to the cylinder.
