Raft strength test of alginate oral suspensions

This test is used to determine the folding endurance of paper or board using the Köhler-Molin, Lhomargy, MIT, and Schopper testers. During the test, a narrow strip of paper is folded forwards and backward in a standardized manner, so that it is subjected to longitudinal stress until it breaks.

A dilatometer is used to determine the linear thermal expansion of a material as a function of temperature. The temperature range of the measurement is generally between 25 °C and 1,600 °C. There is also an option to perform the test in a cryogenic atmosphere, which ranges from -175 °C to 300 °C. The typical heating rate is 3 °C/min. As a result of the measurement, you will get the coefficient of thermal expansion (CTE) and the absolute change in sample length, both as a function of temperature. The testing can be performed in various atmospheres, including air, argon, CO₂, N₂, and O₂. Please contact us to get a quote. The price will depend on the testing conditions, so please specify them as precisely as possible.

UPLC-MS/MS analysis for determining the melatonin content in dietary supplements. According to Regulation (EU) No 432/2012, melatonin supplements may be marketed with the following health claims: "Melatonin contributes to the alleviation of subjective feelings of jet lag." The claim can be used if the product contains at least 0.5 mg of melatonin per portion., "Melatonin contributes to the reduction of time taken to fall asleep." The claim can be used if the product contains at least 1 mg of melatonin per portion..

Bending stiffness testing is performed to evaluate cardboard's stiffness by measuring the resistance to bending with 4-point loading. The results express the bending stiffness of the material in the machine direction and the cross direction.

Tensile tests according to ASTM E21 and ISO 6892-2 are used to determine the mechanical properties of metals and alloys at elevated temperatures. The tests are performed at temperatures up to 1,000 °C. The results include data on multiple properties, including tensile strength, yield strength, and elastic modulus. Please specify the desired testing temperature, strain rates, and the standard you wish the tests to be performed by when requesting a quote. Standard samples should be a minimum of 75 mm in length and 5 mm in diameter, although smaller samples can be tested upon request. The machining of samples can be included in the analysis project. We also offer tensile tests at room temperature.

Test to determine the mechanical and physical properties and safety of cutlery and feeding utensils intended for children from 0 to 48 months of age. The method is based on the EN 14372 standard.

This analysis package is intended to determine if food packaging and beverage bottles can be considered reusable in the framework of the Single-Use Plastic (SUP) Directive (Directive (EU) 2019/904). The following tests are included: Overall migration testing for repeated use with 10% ethanol, 3% acetic acid, and olive oil (simulants A, B, and D2), Dishwasher resistance testing according to EN 12875-1 with 25 wash cycles. The EU Commission’s interpretations of the SUP legislation declare that reusability can evaluated using test method EN 12875-1 (Mechanical dishwashing resistance of utensils). If plastic articles can be washed 25 times in a dishwasher, they can be considered to have been designed for multiple uses without losing their effectiveness and properties. Additionally, food packaging and beverage bottles tested for single-use are not compliant for reuse according to Regulation (EU) No 10/2011. Hence, the test package includes overall migration testing for repeated use to ensure that the article remains inert when reused. By default, testing is done to establish compliance with all types of foods (i.e., moist and dry foods, acidic and non-acidic, fatty foods). Note: this test package is only applicable for articles that have already been tested for food contact as single-use articles. This does not constitute a full test package for compliance according to Regulation (EU) No 10/2011. Please consult our experts for further support.

Creep testing is used to monitor the amount of deformation under a constant load over a set period. It allows us to determine how much a material will deform under a specific load at a given temperature. Stress rupture testing is used to determine the time required for a fracture to occur under constant stress. It provides information on how long a material will last under specific loads and temperatures. Both of these tests are essential in determining the material's load-carrying capacity. The tests are performed according to ISO 204 or ASTM E139 standards at temperatures up to 1,250 °C. There are several testing options under ISO 204 and ASTM E139: Uninterrupted creep tests, where elongation is monitored continuously, Interrupted creep tests, where elongation is measured periodically, Stress rupture tests, where the time to fracture is measured, Verification tests to confirm that the material withstands a given force for a predetermined time without fracturing. Pricing depends on the temperature, load, and test duration. Please contact our experts for a quote.

The Charpy impact test is a standardized test used to measure the impact toughness of a material during fracture. Testing is performed according to the ISO 148-1 standard and can be conducted at temperatures as low as -193 °C. A V-shaped or U-shaped notch is created in the sample, after which a pendulum is used to break it. The test measures how much energy the material absorbs before fracturing, giving insight into the material's ability to withstand sudden impacts.
