FAQs

Extraction systems
Why the air valves have to be replaced regularly?

The new, improved air valve combines valve and filter functions. As usual, ventilation occurs during removal; harmful solvent vapors are blocked. At the same time, the valve membrane absorbs dust and contaminant particles from the incoming air. Since the filter membrane is in contact with solvent vapors, is heavily used through mechanical operation (opening and closing) and absorbs contaminants from the surrounding air, it is recommended that the valve be replaced every 6 months in order to ensure flawless operation.

Can overpressure accrue in a reservoir container with SafetyCap?

No. In this case the valve unblocks automatically in the opposite. For further smooth operation the air valve has to be renewed.

Different colors of air valves?

The red air valve is specially designed for preparative HPLC operation and easily delivers supply amount of up to 400 ml/min (Blue air valve up to 150 ml/min, Orange air valve 150 ml/min and its also made from fire resistant material).

Waste systems
Replace the exhaust filter - why?

Exhaust filters are permanently exposed to vapours, dust particles and pollutants. Exchange saturated filters within their service life to maintain your workspace safety. The filtes are available in different sizes. Filter with size S have to be replaced after 3 months, Filters with size M after 6 months and L after 9 months.

Safety funnels
Not all of the funnels have a hinged lid - why?

Funnels without a hinged lid have an integrated ball valve which floats and closes automatically after filling the funnel with liquid waste.

Funnels in black and white?

Funnels in black are made from electrical conductive plastic and are delivered with an grounding clamp.

Level control
Different sensors of level control?

Disc sensor: Fill level detection without touching the content of the container. The sensitivity of the sensor can be adjusted to different wall strengths. The signal box emits an optical and acoustic signal before a previously set fill height is reached. Suitable for all containers made of glass and non-conductive plastic. Just connect the sensor to the container wall at the desired fill level (fastening material is included with delivery), connect mains plug – done. No technical modifications to the receptacle are required.

SafetyWasteCap: For containers made of ­conductive plastic or metal, the level control can be ­accomplished through the ­closure. SafetyWasteCaps with electronic level control can be connected to our signal boxes.

Laboratory installation
When Laboratory installation elements have to be renewed?

Components have to be tested regularly by the user and replaced if necessary. Tubes have to be renewed at the latest after 2 years.

Container
Which size of thread has my container?

S.C.A.T. safety closures are available for a wide range of ­different container threads. In category containers, you will find the suitable containers for every thread size. In the category of Waste systems you will find suitable SafetyWasteCaps for your containers.

If you wish to use already available containers, we are ­providing you with an aid in determining thread size here.

Accessories
Fittings of earlier generations are suitable with new SafetyCaps?

Yes! Accessorie from S.C.A.T. Europe can be used generation-seamless. All products of our system are compatible among themselves.

General questions
Chemical compatibility to products

Due to the wide variety and the different compositions of solvents and substances available on the market, we can assume no guarantee for chemical compatibility. The materials with the best resistance according to the most up-to-date knowledge have been selected for S.C.A.T. products with particular consideration of the requirements for working with aggressive fluids.

You may obtain information regarding compatibility with specific substances from the manufacturer of your chemicals or other expert sources.

We would be pleased to offer you consultation during selection of suitable products for your application. The responsibility for the selection of the chemicals used lies with the end user. S.C.A.T. Europe offers no guarantee for the results and assumes no obligation or liability concerning the use of these products as regards their chemical compatibility, or abrasive effects.

There are new GHS labels?

At January 20, 2009 the regulation (EC) No. 1272/2008 – CLP-regulation – became effective. It regulates the classification, labeling and packaging of substances and mixtures (Regulation on classification, labeling and packaging of substances and mixtures, short CLP) and replace the European regulation 67/548/EEC and the Dangerous Preparations Directive 1999/45/EC from 2015 completely.

The CLP Regulation is based on the recommendation of the UN, which dates back to the 1992 Sustainability Conference in Rio de Janeiro, to establish a global corporate system for classification and labeling of chemicals (Global Harmonized System, UN GHS). This represents a compromise by established systems primarily in North America, the EU and the regulation for dangerous goods.
