Spirit levels are tools commonly used in construction, woodworking, and other fields where accurate leveling is important. They consist of a straight bar or tube filled with liquid (usually alcohol) and a bubble. When the bubble is centered between two lines marked on the tube, it indicates that the surface being measured is level. The Ronix RH-9417 spirit level is simple and easy to use, requiring no batteries or AC power. It is compact and lightweight, making it easy to carry and use in tight spaces. It also features level bubbles that accurately measure horizontal, vertical, and 45° tilt angles. The level is durable and impact resistant due to its aluminum housing. Plus, this practical hand tool is easy to read with clear, visible level bubbles.

The major difference between our standard capillaries and conical capillaries lies in the different opening diameters on both ends. Whereas standard capillaries are manufactured with the redrawing-method conical capillaries are produced in a discontinuous process. Materials Soda-lime glass (AR, I860, PH360 etc.) gamma sterilized soda-lime glass Borosilicate glass (DURAN©, PYREX©, SIMAX© etc.) Neutral glass (FIOLAX© and DUROBAX©) Aluminum silicate glass (Schott 8252/8253) Lead glass (lead content up to 28%) Sealing glasses for various metals such as: kovar, molybdenum, steel, silver, platinum, palladium Process of Production During the production process of the conical capillaries a straight tube or capillary is heated and drawn. By drawing the capillary a pointy conical, tapered form, a so-called double-tip, is formed. The tip can be parted in the capillary’s smallest diameter and results in a larger diameter on one side which is determined by the blank used in the process, as...
