The Micronucleus Assay is an in vitro study to evaluate the mutagenicity/genotoxicity induced by chemical substances:

OECD 487 In Vitro Mammalian Cell Micronucleus Test

• detection of micronuclei in the cytoplasm of interphase cells
• test system: human lymphocytes freshly obtained by venipuncture

We have increased our capacities and can offer good timelines!

For Biocidal Spray Products we offer specific analyses in addition to the standard requirements for biocides:

• spray pattern
• internal pressure of spray cans
• discharge rate
• clogging

The tests could be integrated into stability studies such as shelf life, accelerated or cold storage.

The Mouse Lymphoma Assay acc. to OECD 490 (short “Moly”) and the Micronucleus Assay acc. to OECD 487 are both in vitro studies to evaluate the mutagenicity/genotoxicity induced by chemical substances.

OECD 490: In Vitro Mammalian Cell Gene Mutation Tests Using the Thymidine Kinase Gene

• detection of gene mutations
• test system: mouse lymphocytes (L5178Y TK+/- clone (3.7.2C))

OECD 487: In Vitro Mammalian Cell Micronucleus Test

• detection of micronuclei in the cytoplasm of interphase cells
• test system: human lymphocytes freshly obtained by venipuncture

We have increased our capacities and can offer good timelines!

An Automated External Defibrillator(AED) can save lives and it is much easier to use than you would expect. Since this is a matter close to our heart, in the context of the biannual safety check we had a briefing and demonstration of LAUS’ AED. Not only First Aiders could participate, but everyone interested was welcome to see how easy it could be operated. Luckily we yet have not had a situation where we needed it, but this training will hopefully encourage people to act where needed.

We hope you had a good start into the New Year and in this context we wish you Health and Happiness for 2023!

For the determination of the viscosity of liquids acc. to OECD 114 we now have two options:

- falling sphere viscometer (acc. to Höppler) in a range between 0,6 – 70.000 mPa*s and

- rotational viscometer in a range between 3 – 1.000.000 mPa*s

This allows us to test Newtonian as well as Non-Newtonian fluids regarding dynamic viscosity and calculate the kinematic viscosity.
