Glass Tubes

"Glass Tubes" is listed under  Gifts & Crafts Agents Category

Glass Tube of Various Diameter and ThicknessGlass tubes are made of soda-lime, borosilicate or quartz material and they have broad range of quality. Glass tubes are widely used in laboratory, chemical industry, biology industry, gardening, and so on.According to different dimension and accuracy, glass tubes can be divided into normal glass tube, precision glass tube and heavy wall capillary tube three kinds. The smallest tolerance we can achieve is 0.005 mm, which requires very high technology. Our glass tubes have stable chemical property and can resist most acid and alkali. The glass tubes can also work under high temperature for a long time.With good chemical, mechanical and thermal properties, small tolerance and various dimension, the glass tubes are widely used in daily life, industry and laboratory.Five clear glass tubes with polishing edge lie on the table.GT-1: The straight polished glass tubes have good thermal and chemical properties.Three glass tubes with different dimension are on the table.GT-2: Various sizes glass tubes are used in different equipment.SpecificationMaterial: soda-lime, borosilicate, quartz.Diameter and ToleranceGlass tubes diameter and tolerance Inside diameterToleranceOutside diameterToleranceNormal glass tube5-500 mm0.5 mm5.1-550 mm0.5 mmPrecision glass tube5-500 mm0.005 mm5.1-550 mm0.005 mmHeavy wall capillary tube0.025-0.508 mm0.02 mm0.5-6.4 mm0.4 mmA piece of glass tube is measured carefully on the outside diameter, thickness and length.We will check carefully the outside diameter, thickness and length of the glass tubes to control the tolerance.Two heavy wall capillary tubes with clear surface and polished edge lie on the table.GT-3: The heavy wall capillary tubes have strong acid, alkali, high temperature resistance ability.Six precision glass tubes with minor tolerance are on the ground.GT-4: Producing the precision glass tubes requires very high technology and can meet the requirement for precise instruments.Length: 10 mm - 2500 mm.Color: red, green, pink, yellow and so on.Edge handling: polishing.thermal propertiesGlass tubes thermal propertiesMaterialSoda-limeBorosilicateQuartzSiO2 content60 Percent - 75 Percent> 81 Percent> 90 PercentDensity at 25 & 176C2.53 g/cm32.23 g/cm32.20 g/cm3Coefficient of thermal expansion8.6 & 215 10-6 m/k3.3 & 215 10-6 m/k5.5 & 215 10-7 m/kSoftening point726 & 176C820 & 176C1780 & 176CMelting point780 & 176C1680 & 176C2000 & 176CAnnealing point546 & 176C560 & 176C1120 & 176CTemperature for short time400 & 176C500 & 176C1500 & 176CTemperature for long time350 & 176C450 & 176C1200 & 176CSpecific heat0.18 J/kg & 176C0.9 J/kg & 176C670 J/kg & 176CFeatures and advantagesAcid and alkali resistanceThe acid and alkali resistance is high, especially quartz, which do not react with any acid except hydroflouric acid. The stability of glass is 30 times of ceramic and 150 times of stainless steel.Tight dimensional toleranceThe dimension is accurate and the tolerance is tight. Whats more, we can customize according to your requirement.Low coefficient of thermal expansionOur glass tubes have low coefficient of thermal expansion. The softening point can reach 1500 & 176C, so that the glass tube can withstand temperature as high as 1200 & 176C.Precise boringAs for our precision glass tube, the tolerance can be as small as 0.005 mm.Excellent outlookingOur glass tube are clear, bright and polishing. We can also color it as your requirement.ApplicationGlass tubes used in laboratoryBecause of its stable chemical property, various sizes of tubes, as connecting pipe, guide tube and so on, are widely used in chemical and biology laboratory.Glass tubes used in chemical industry, petrochemical industry, biochemical pharmaceutic, military industry, metallurgy, water treatment and so on.Glass tubes used as decorationDue to t
