Quick Stability & Resuspendability Measurement of Adjuvants and New vaccine generation by Turbiscan
SOME PERSPECTIVE ON COVID-19 VACCINES
As of early-December, there are 237 coronavirus vaccine projects1 around the world today, developed using very different techniques.
Some vaccines under development are using new methods without adjuvants such as mRNA based vaccines (Ex: Moderna, Pfizer). These vaccines can be developed faster but they require specific storage conditions and two injections to be effective.
Other vaccines are based on “classic” approaches such as using adjuvants but this requires a longer development period. Additionally, this classic approach usually takes less expense to manufacture.
Even if adjuvant are not used in the today’s COVID-19 vaccines, experts in the community believe 2 that the next generation of COVID-19 vaccines will use adjuvants to boost immune response.

The Benefits of Handheld Particle Counting with the HandiLaz® Mini II
- Created: Tuesday, 17 November 2020 07:12
Modern manufacturing frequently requires clean environments such as cleanrooms that are designed, constructed, and sustained to enable the highest yields possible while also hitting predictable throughput targets. This commonly involves achieving a specified cleanroom classification to establish the level of cleanroom performance, and subsequent sustaining efforts that are efficient and nimble. Having the right particle detection equipment for this application is necessary to accomplish these tasks.

Cellulose is the world’s most abundant biopolymer and is responsible for the strength in most plants. The key to the strength of this material is its structure: carefully ordered cellulose nanofibrils (CNFs) and cellulose nanocrystals (CNCs) build-up to form large, macromolecular constructs.1
These two types of nanocellulose have a high aspect ratio and show great promise for increasing strength in composite materials and stabilizing suspensions. CNFs and CNCs are also non-toxic, biocompatible, biodegradable, and are obtained from a sustainable source – an increasing focus in many industries.1,2

This is the first particle counter with built in vacuum designed for use with the Vaporized Hydrogen Peroxide (VHP) process.
Safety in oil transformers due to PAMAS particle counters
- Created: Monday, 19 October 2020 14:38
Due to the high transfer voltage, transformers heat up significantly and thus need to be cooled. Power transformers are usually cooled with oil. The insulating oil does not only serve as coolant, but it also insulates empty spaces between conductive materials.
Replacing Settle Plates with Active Air Sampling
- Created: Monday, 12 October 2020 12:14
Settle plates were adequate in the past to meet regulations, but the new approach requires active air sampling.
Active Air Sampling for settle plates by Particle Measuring SystemsThe most universally applied method for cleanroom classification is the one suggested in 1963 by Federal Standard 209 of the USA. In this standard the number of particles equal to and greater than 0.5 µm is measured in one cubic foot of air. This count is then used to classify the room (1 particle = class 1; 10 particles = class 10…). In the same period, scientific publications concerning healthcare facilities suggested that airborne particles carrying micro-organisms associated with human disease were usually found in the 4-20 µm equivalent diameter range. This contamination can be detected by settle plates.
The Pamas SBSS - a user perspective
- Created: Wednesday, 16 September 2020 11:17
Recently I had the opportunity to use a Pamas SBSS ( Syringe Bottle Sampling System) at a customer. The instrument is the flagship liquid particle counter from Pamas GMBH.
What struck me immediately is how easy the instrument is to use! I am so used to controlling an instrument via software and PC these days, it is almost a novelty to just control the instrument via a touchpad!
It has a simple menu system that allows the user to operate the instrument directly ( ofcourse normal software control via PC is also possible).

Data Trending and Alert/Action Levels definition are new requirements in the latest EU GMP Annex 1, Revision 12 draft. Trends allow you to quickly and easily identify changes in your cleanroom data and leverage this to make effective decisions, changes, and adjustments often before problems occur. Here we discuss three key components in the latest Annex 1 draft:

RHEOLACT’ (MP0007019) is an innovative regional project, co-funded by the European Union. The Engineering School INP Purpan, the cheese producing company Marzac, and Formulaction are part of the project consortium. The focus of the work is to use new measurement techniques for the characterization of dairy products. In two main working groups, methods are developed for the use of RheolaserMASTER as a powerful tool for characterization of the textural properties of yogurt and for determination of the optimal cutting time of soft cheese preparations.

Have you ever tried to perform particle measurement of therapeutic protein solutions? You will encounter several challenges. There is extremely limited sample available because therapeutic protein solutions are very expensive. In addition, the samples are usually highly viscous. How can reliable values be measured without diluting the samples or having to resort to the subjective and time-consuming microscopic analysis?

The properties of superhydrophobic surfaces are highly desirable in many industries and applications. Unfortunately these surfaces often suffer from low durability. They are for example easily scratched by hard objects and their superhydrophobicity is destroyed.
In the latest Nature cover story Wang, D., Sun, Q., Hokkanen, M.J., Ras, R.H.A. et al. introduce a new strategy to create superhydrophobic surfaces that have a high mechanical stability. They designed a material matrix that combines the superhydrophobic nanostructure with a highly durable macrostructure. This new material can be even scratched with a razorblade or with sandpaper without losing its superhydrophobic properties. Due to its transparent nature the new material matrix is an ideal candidate for a new kind of self-cleaning cover material for solar panels.

Turbiscan Classic, Lab , Tower or AGS - which model is best for me ?
Looking at the 4 models ( Turbiscan Classic 2/ Lab/ Tower/ AGS) it is easy to get confused and the natural question is to ask which model is best for me ? This article will attempt to give greater clarity on the differences between the models and the unique features each model offer.
All 4 models scan a liquid or paste sample for instability by detecting very small changes in sample concentration or size in tiny slices of the sample in a glass tube. This technology (invented by Formulaction back in the 1990's) offers an objective, reliable and above all quick way to decide if a product or formulation is stable or unstable. In most cases product stability is determined in 2 to 5 days at most. Multiple measurements is made over minutes to hours (depending on the sample).
