HKL-87 Petroleum Wax Melting Point Apparatus
Overview
HKL-87 Petroleum Wax Melting Point Apparatus (Cooling Curve Method) conforms to ASTM D87 Standard Test Method for Melting Point of Petroleum Wax (Cooling Curve). A specimen of molten wax in a test tube fitted with a thermometer or equivalent temperature measuring device is placed in an air bath, which in turn is surrounded by a water bath held at 16 to 28°C (60 to 80). As the molten wax cools, periodic readings of its temperature are taken. When solidification of the wax occurs the rate of temperature change decreases, yielding a plateau in the cooling curve. The temperature at that point is recorded as the melting point of the sample.
Features
The cooling bath has two wells which allow for separate temperature control. With compressor refrigeration, each well’s temperature can be set individually without affecting the other, making operation easy and comfortable.
Having a compressor refrigeration and fan-assisted air cooling, the system starts to cool immediately after the refrigeration switch is turned on.
The device is equipped with an imported digital temperature controller that regulates temperature with high precision and allows the operator to adjust the setpoint freely within the effective cooling temperature range. The sensor, which is a Pt100, can detect temperature sensitively and provides high resolution while maintaining excellent anti-interference ability and accurate temperature control.
The compressor of this instrument is very compact and lightweight. It also runs quite stably without any vibration. In short, it is perfect for laboratory use.
It is fitted with a copper cooling chamber that has powerful cooling ability, can handle two samples at the same time, and is capable of continuous sample testing.

FAQ
Q1: What standards does this product (HKL-87 Petroleum Wax Melting Point Apparatus) comply with?
A: HKL-87 Petroleum Wax Melting Point Apparatus (Cooling Curve Method) conforms to ASTM D87 Standard Test Method for Melting Point of Petroleum Wax (Cooling Curve). This test method is applicable for determining the melting point (cooling curve) of petroleum wax. However, it is not suitable for waxes of the petrolatum group, microcrystalline waxes, or blends of these waxes with paraffin wax or scale wax.
Q2: The working principle of HKL-87 Petroleum Wax Melting Point Apparatus?
A: A specimen of molten wax in a test tube fitted with a thermometer or equivalent temperature measuring device is placed in an air bath, which in turn is surrounded by a water bath held at 16 to 28°C (60 to 80). As the molten wax cools, periodic readings of its temperature are taken. When solidification of the wax occurs the rate of temperature change decreases, yielding a plateau in the cooling curve. The temperature at that point is recorded as the melting point of the sample.
Q3: Significance and use of HKL-87 Petroleum Wax Melting Point Apparatus?
A: Melting point (cooling curve) is a test that is widely used by wax suppliers and consumers. It is particularly applied to petroleum waxes that are rather highly paraffinic or crystalline in nature. A plateau occurs with specimens containing appreciable amounts of hydrocarbons that crystallize at the same temperature, giving up heat of fusion, thus temporarily retarding the cooling rate. In general, petroleum waxes with large amounts of non-normal hydrocarbons or with amorphous solid forms will not show the plateau.
Q4: How can I obtain the user guides and technical documentation for the products?
A: In order to assist you in your achievement, we provide you with easy access to a variety of resources such as product manuals, quick start guides, and application examples. All that is required is to visit our website or get in touch with our customer service team to get the documents necessary.
Q5: What is the minimum order quantity? How long is the delivery lead time?
A: The minimum order quantity is one unit, and delivery is approximately 20 days after advance payment.
