Small enough to care and big enough to deliver




If you want to get access to data sharing under chemical legislation around the world, you need a Substance Identity (also known as “Sameness”) of your substance.


- China REACH

- Korea: AREC („Act on the Registration and Evaluation of Chemical Substances“), K-REACH

- Türkiye: KKDIK, Türkiye REACH

- United Kingdom: UK REACH

Our experts will gladly choose the required analyses for your substance. Ask us for a quotation.

New Registrants of an Existing Substance (NRES)

A NRES is a new registrant of a substance that was previously registered under EU REACH before 1 January 2021 by any legal entity.

First step in the process is to submit an Article 26 inquiry according to UK REACH. When the NRES status has been confirmed, 2, 4 or 6 years plus 300 days from the end of the transition period (i.e. from 31 December 2020) remain for the submission of the full information requirements.

Particle Size Distribution 0.3 nm – 3,500 µm

With Laser Diffraction and Dynamic Light Scattering techniques LAUS is now able to perform measurements

  • from 0.3 nm to 3,500 µm particle size
  • in wet dispersion (0.3 nm - 850 µm)
  • in dry dispersion (100 nm - 3500 µm)
  • for solids, suspensions and aerosols

We work according to current guidance

  • OECD 110
  • ISO 22412 Particle size analysis — Dynamic light scattering (DLS)
  • ISO 13320:2020 Particle size analysis - Laser diffraction methods
  • Many ASTM and U.S. Pharmacopeia methods

Testing is offered with and without GLP and could be used for R&D as well as for regulatory purposes.

An Article 26 inquiry under UK REACH requires a Substance Identity Profile

If you are a non-GB based manufacturer or formulator your OR must submit analytical data generated from a sample manufactured by you or your non-GB based manufacturer for an Article 26 inquiry under UK REACH:

An inquiry dossier should contain information:

- about the potential registrant

- about the identity of the inquired substance

- where the potential registrant would need to carry out new studies, including those involving vertebrate animals.

LAUS can support you with both, the OR service and the generation of the analytical data for the substance identity.

Article 26 inquiry under UK REACH

First step of any new registration under UK REACH is to submit an Article 26 inquiry. There are two more szenarios where you should submit an Article 26 inquiry to HSE:

- You have completed the DUIN and would like to start with the data sharing process.

- DUIN is not possible since you do not fulfill prerequisites.

After the inquiry you will receive your inquiry number and become part of a substance group - a group of potential co-registrants of the same substance (formerly known as SIEF under EU REACH). This will enable you to engage in the data sharing process for a successful registration within the applicable timeframe. Questions? Click here or contact us!

See you there! Chemspec 2022 in Frankfurt

LAUS will be visiting Chemspec in Franfurt on May 31 and June 1. We offer GLP testing for regulatory purposes as e.g. for the registration of your chemicals under REACH, for CLP/GHS and much more.

This will be a good opportunity to meet and to discuss upcoming projects which require testing/experimental endpoints.

If you are interessted, please, contact us for an appointment. We are looking forward to meeting you in Frankfurt!

On May 19, 2022, the “Firmenlauf Südpfalz” finally took place as a live event after two virtual runs.

3,012 participants from 164 companies completed the 5 km course and were happy about their sporting successes or simply about the community experience, which had not been possible for so long. LAUS had 9 participants running. Congratulations to everyone!

V for Vapour Pressure

LAUS testing ABC:

V for Vapour Pressure

LAUS is the leading GLP lab for the determination of the Vapour Pressure using the Effusion Method (Knudsen Cell) according to OECD 104 / EU A.4. We are able to measure vapour pressures as low as 10E-12 Pa.

This method is based on the estimation of the mass of test substance flowing out per unit of time of a Knudsen cell under ultra-vacuum conditions. The mass of effused vapour is then being obtained by weighing the cell. Data are being collected between 30 – 150 °C, values for 20 and 25 °C are being calculated.

By operating two custom produced measuring apparatuses in parallel we have very high capacities and minimum delays. With more than 20 years of experience, we offer our advice even for difficult substances.

The Vapour Pressure is a key physico-chemical parameter for the assessment of a substance. It provides an indication of the evaporation rate and relates to the tendency of particles to escape from the liquid or solid phase. A substance with a high vapor pressure at room temperature is considered as volatile.

ECHA draft decisions

According to its “Progress in evaluation 2021” report ECHA performed 300 full compliance checks (CCHs) and 227 testing proposal examinations (TPEs) and issued 467 draft decisions: 280 on the abovementioned compliance checks and  187 on testing proposal examinations. That means 93% of dossiers require additional information.

Number of requests in 278 compliance check decisions:

  • Mutagenicity/Genotoxicity 260
  • Long-term aquatic toxicity 344
  • Physico-chemical properties 60

Number of requests in 165 testing proposal decisions 79/41/8

  • Mutagenicity/Genotoxicity 79
  • Long-term aquatic toxicity 41
  • Physico-chemical properties 8

LAUS has a great team with particular expertise in these areas and a lot of experience with difficult substances. If you are concerned and need additional data, don’t hesitate to contact us.
