Freezing Point of Aqueous Engine Coolant SolutionTest MethodDetermines the freezing point of aqueous engine coolant solutions bycooling a sample with continuous agitation until a plateau is observedin a time-temperature curve.Freezing Point Apparatus• Conforms to ASTM D1177 specificationsDetermines freezing points of aqueous engine coolants. Includes 200mLfreezing tube with drilled cork, outer flask, motorized stirrer, clamps andstand. Similar to K29700 Freezing Point Apparatus.Electrical Requirements:115V 60Hz220-240V 50Hz220-240V 60HzOrdering InformationCatalog No.Order QtyK29750 Freezing Point Apparatus, 115V 60Hz 1K29758 Freezing Point Apparatus, 220-240V 50HzK29759 Freezing Point Apparatus, 220-240V 60Hz250-000-75F ASTM 75F Thermometer Range: –35 to +35°F 1250-000-76F ASTM 76F Thermometer Range: –65 to +5°FFor NIST traceable certified thermometers, please refer to the ASTM Thermometer section onpages 184 through 191.K29750 Freezing Point ApparatusColor of Maleic and Phthalic AnhydridesTest MethodMolten samples of maleic or phthalic anhydride are compared withPlatinum-Cobalt color standards for determining sample purity and thequalitative stability in the presence of contaminants. High color contentnormally indicates contamination.Anhydride Purity Bath• Conforms to ASTM D3366 specifications• Redundant overtemperature protection circuitry• Microprocessor-based temperature controllerElectrically heated aluminum block features a microprocessor-basedtemperature controller with overtemperature protection circuitry and a dualLED temperature display. The heating unit provides temperature stability,heating rates, and minimal temperature gradients which exceed ASTMspecifications, and is housed in an insulated steel cabinet with a chemicallyresistantpainted finish. Up to six samples can be tested at a time usingNessler tubes. Visual color comparisons are made against solutions ofPlatinum-Cobalt color standards.

Automatic Melting Point Range ApparatusAutomatic Melting Point Range ApparatusTest MethodThe melting point of a crystalline solid is the temperature at which the solidto liquid phase transition occurs, referenced at one atmosphere (1 ATM)of pressure.• Conforms to BP Appendix 5 - Method 6 and GLP specifications• Readily interchanged between automatic and manual detection of meltingpoint ranges• Intelligent Lamp Intensity Control with Soft Start• Storage capacity for up to 20 sample tests• User-interactive software and data entry, including easy alphanumericentry of sample name, ID number, and date• User selectable operating modes:- AUTO detection mode: Start/end of melting point range is automaticallydetected by a photosensing infrared device. The melting process isrecorded and viewed on-screen in real-time by a CCD camera.- MANUAL detection mode: Start/end of melting point range can beselected manually with a key-press by user. Sample melting point canbe determined as per BP method by ‘Heat & Cool’ temperature function.As above, the melting process is recorded and viewed on-screen inreal-time by a CCD camera.The Automatic Melting Point Apparatus is the latest technology formicroprocessor-based determinations of melting point ranges of crystalline,powdered and polymeric materials, and is used to assess sample purity.Requires approximately 5mg of sample spread uniformly on a glass slide,covered with a glass coverslip. The slide is placed on a uniformly heated, roundfurnace and subjected to a heating profile as required by the user. Precisetemperature control gives reproducible results to within 1%. The unit containsan automatic temperature safety cut-off feature if no melting points aredetected 15°C above the expected melting point or if the oven reaches 315°C.The melting process is magnified, recorded, and viewed on-screen in real-timeby a CCD camera. The change in physical appearance of the sample withrespect to temperature is recorded, and the start/end of melting is observedautomatically. A representation of the entire process can be printed out ingraphical form for validation.Dimensions lxwxh,in.(cm)Main Unit: 16 1 ⁄2x12 1 ⁄4x13 (42x31x33)Monitor: 8x5 1 ⁄2x5 1 ⁄2 (20x14x14)Net Weight: Main Unit: 22 lbs (10 kg)Monitor: 1.8 lbs (0.8 kg)Shipping InformationWeight: 29 lbs (13 kg)Dimensions: 3.6 Cu. ft.K90190 Automatic Melting Point Range ApparatusSpecificationsConforms to the specifications of:BP Appendix 5-Method 6; GLPVisual Image: 10x magnified displayed on monitorTemperature Range: ambient + 5 to 315°CHeating Rates: 0.2, 0.5, 1.0, 2.0, 3.0, 6.0, 12.0°C/minTemperature Readability: 0.1°CCooling Time: 20 minutes (300°C to ambient)Temperature Accuracy: ±0.5°C (ambient + 5 to 200°C)±0.8°C (200 to 315°C)Sample size: 5 mg (approximately)Sample Holder: Glass Slide ≤1mm ±0.02mm thickSample Cover: Glass Coverslip ±0.17mm thickTemperature Sensor: Pt-100 (2 wire RTD)Test Storage: Up to 20 tests with parametersElectrical Requirements:115V, 60Hz, Single Phase220V, 50Hz, Single PhaseCatalog No.K90100K90190Ordering InformationOrder QtyAutomatic Melting Point Range Apparatus,115V 60Hz 1Automatic Melting Point Range Apparatus,220V 50HzAccessoriesK90100-1 Glass slides (pack of 500)K90100-2 Cover slips (pack of 1000)K90100-3 Sampling jig69
