Differential Scanning Calorimetry (DSC): Measures the heat flow into and out of the sample. The sensor output is in watts (W).

Differential Scanning Calorimetry (DSC) is a widely used thermal analysis technique. It is used to measure the enthalpy changes of a sample as a function of temperature or time due to physical and chemical property changes. It is applied for material identification and characterization.

Differential Scanning Calorimetry (DSC) is used to analyze and study materials such as thermoplastics, thermosetting resins, elastomers, composite materials, metals and alloys, adhesives, food, pharmaceuticals, and chemicals.

Differential Scanning Calorimeter DSC 3+Advantages:

Major breakthrough in DSC sensor technology

Excellent sensitivity and superior resolution

Do not compromise when selecting the core component of DSC—the sensor. Mettler Toledo's MultiSTAR™ sensor successfully integrates a multitude of critical features that traditional sensors cannot achieve and have been impossible to date. These features include high sensitivity, exceptional temperature resolution, a perfectly flat baseline, and long-term durability.

Temperature resolution

The signal time constant determines how effectively adjacent or overlapping thermal effects can be separated. Sensor ceramic materials with low heat capacity and high thermal conductivity deliver outstanding performance.

Baseline

An innovative star-shaped arrangement of thermocouples around the sample and reference crucibles fully compensates for any potential temperature gradients, ensuring a flat baseline and reproducible measurement results.

Sensitivity

A major breakthrough in sensor technology enables us to provide highly sensitive sensors for DSC instruments, allowing the measurement of weak thermal effects. The critical instrument parameter of signal-to-noise ratio is determined by the number of thermocouples and their specific arrangement.

DSC 3+ features a modular design

Suitable for various industries including industrial development, academic research, production, and quality assurance, supporting both manual and automated operation.

Touchscreen

If the DSC is installed away from the computer running STARe software, you can set up independent sequence segments directly at the instrument terminal. The intuitive and adaptable touchscreen allows easy switching of display interfaces and control of furnace opening or closing.

OneClick™ operation

The touchscreen with OneClick operation displays the measurement status and even allows remote monitoring of the instrument. The OneClick function enables easy and efficient initiation of predefined methods.

Perfect ergonomics

Ergonomics have been improved: during manual sample loading, hands can rest on the ergonomically designed support surface.

Two-level calibration provided

Standard calibration

Standard calibration for any thermal analysis instrument supports a single heating rate

• Procedures executed according to GMP-approved standard operating procedures (SOP)

• Automatically generates Mettler Toledo standard certificates

Expert calibration

Expert calibration for DSC and TGA/DSC supports multiple heating rates

• Procedures executed according to GMP-approved standard operating procedures (SOP)

• Automatically generates Mettler Toledo standard certificates

Reliable automation

Operates 24/7 with Swiss watch-like precision

The automatic and efficient autosampler, as a sophisticated automation option, can run reliably year-round without interruption. When combined with STARe software, automation capabilities are further enhanced thanks to the unique FlexCal™ calibration concept, which always selects the correct correction parameters and automatically evaluates results.

Unique lid piercing accessory

The autosampler can remove the protective lid of the crucible or pierce the sealed aluminum lid before measurement. This unique feature prevents samples from absorbing or losing moisture between weighing and measurement, and also prevents oxidation of oxygen-sensitive samples.

Automatic furnace lid

The automatic furnace lid can be opened or closed with a simple button press or by activating the SmartSens infrared sensor, eliminating the need to manually remove and replace the lid. The optimized design of the triple-layered silver furnace lid with a heat shield effectively isolates the test cell from the environment.

Universal gripper

The universal gripper can handle various types of Mettler Toledo crucibles.

Innovative accessories

Expands measurement capabilities

The DSC instrument can be easily equipped with options such as a microscope or photocalorimeter. While the sample is heated or cooled in the DSC, users can capture images of the sample via the DSC microscope. The DSC photocalorimetry scanning system allows you to expose the sample to light of a specific wavelength range and intensity for a (customizable) period and then record the heat from the sample.

DSC microscope

DSC curves often show thermal effects that cannot be immediately explained. In such cases, a microscope helps directly observe changes in the sample. This versatile optical accessory can be used with any Mettler Toledo DSC. It consists of an optical system, a CCD camera, and image acquisition and processing software.

DSC photocalorimeter

The DSC photocalorimeter accessory can characterize UV curing systems. You can study light-initiated curing reactions and measure the effects of UV exposure time, UV intensity, and temperature on material properties.

Light sources for UV measurements

Different types of light sources:

• Light sources for a specific (UV) wavelength range

• Light sources for a specific (visible light) wavelength range

• LED-based light sources (available wavelengths: 365, 385, or 400 nm)

Various options: The table below lists the DSC 3+ configurations to meet every need and requirement.

• = Optional

The system can be upgraded in the future. The modular design enables "buy now, improve later"—practical accessories can be added or furnace units replaced at any time.

Set furnace atmosphere, programmable gas flow, and gas switching

The furnace chamber can be purged with a set gas flow. The software-controlled mass flow gas controller measures and regulates the gas flow between 0 and 200 ml/min, automatically switching between up to four gases. Gases such as air, nitrogen, oxygen, argon, CO2, CO, and inert hydrogen can be selected for regulation and switching, expanding experimental potential.

Temperature range and cooling options

You can choose the appropriate cooling method based on your measurement temperature range. The built-in cooler is a sealed system requiring only electricity, offering advantages where liquid nitrogen is unavailable or not used. Liquid nitrogen cooling provides greater adaptability, allowing measurements across the entire temperature range.

Crucibles for thermal analysis

Ensures reliable results

Crucibles are used as sample containers during thermal analysis measurements. They ensure the sensor is not contaminated by the sample during measurement. The type of crucible used can significantly impact the quality of the results and the DSC measurement unit. Considering relevant factors before measurement often saves time in later curve analysis.

Wide selection of crucibles

We offer crucibles for every application. Crucibles are made from various materials, with capacities ranging from 20 μl to 900 μl, suitable for atmospheric to high-pressure conditions. All crucibles are compatible with the autosampler.

Crucible press

The crucible press makes sealing crucibles easy. Under the pressure generated by the piston, the press cold-welds the crucible and lid through compression. By adjusting the type and height of the plunger and mold, the crucible press can accommodate various types of crucibles.

Crucible kit

The crucible kit provides essential tools for sample loading and handling of crucibles and lids:

• Funnel for loading samples into crucibles

• Tweezers for handling samples, crucibles, and lids

• Various types of needles for piercing lids and rubber backing pads

• Crucible trays for handling and safely placing crucibles into the instrument

When a sample undergoes endothermic or exothermic processes, heat flow differences arise due to thermal effects such as melting, crystallization, chemical reactions, polymorphic transitions, evaporation, and many other processes. This allows measurement of valuable information, such as specific heat capacity and its changes during glass transition.
