Specification Brand : Labwang BulletPoint : 24/40 ground joint for all BulletPoint1 : 【 Application of Special Gravity Cup 】 QBB type coating special gravity cup is designed and manufactured according to GB6750-86 "determination of density of paint and varnish". Used to determine the density of liquid paints, varnishes, and related products at specified temperatures (or determination of specific gravity). BulletPoint10 : Recommended for use with 3M Personal Safety Products BulletPoint2 : 【 High Quality Aluminum Alloy Material 】 Made of aluminum alloy (stainless steel) material, QBB-37, 50, 100 type coating specific gravity cup (mass / volume cup) with 37ml, 50ml and 100ml. BulletPoint3 : 【 Special Gravity Cup Paramater 】 Thermometer: graduation is 0.1 degree C, accuracy is 0.2 degrees C; Water bath or constant temperature requirements: if the test accuracy is high, should be kept at the test temperature of the range of 0.5 C, for the production control should be maintained at the test temperature of + 0.2 C;Analytical balance (or electronic name): accuracy of 0.2 mg (mg). BulletPoint4 : 【 Matters Needing Attention 】 After cleaning the proportion cup, immediately clean, cool dry or dry (preferably coated with protective oil), placed in the box, room temperature storage. BulletPoint5 : 【 Volume Calculation of Specific Gravity Cup 】 Due to the changes of environment temperature, humidity and pressure, the physical and chemical properties of the specific gravity cup of the metal may cause very small changes in the volume of the specific gravity cup. If the measurement accuracy is very high, the volume of the specific gravity cup should be calculated periodically. BulletPoint6 : Unique coating resists clogging for long use BulletPoint7 : Suitable for wet sanding and dry sanding BulletPoint8 : Sandpaper color will not discolor the surface you are sanding BulletPoint9 : Great for construction, woodworking, carpentry, and home improvement projects Capacity : 60 milliliters Color : QBB-50ml ExternallyAssignedProductIdentifier : 4953363192140 ExternallyAssignedProductIdentifier1 : 0714133272943 ExternallyAssignedProductIdentifier2 : 714133272943 IncludedComponents : 463-000-TRI-4 ItemName : Glass Vacuum Buchner Funnel with Perforated Plate 60ml Joint 24/40 ItemPackageDimensions_Height : 21.8 centimeters ItemPackageDimensions_Length : 5.5 centimeters ItemPackageDimensions_Width : 9.3 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : science-lab-ware-sets Manufacturer : Labwang factory Material : Glass ModelNumber : NA38AA NumberOfBoxes : 1 NumberOfItems : 1 PackageLevel : unit PartNumber : G100211 ProductDescription : Glass Vacuum Buchner Funnel with Perforated Plate 60ml Joint 24/40 ProductExpirationType : Does Not Expire ProductSiteLaunchDate : 2018-01-16T08:00:00.000Z Size : 50Ml SupplierDeclaredDgHzRegulation : unknown TotalUsbPorts : 1 UnitCount : 1
