FAQ - Frequently asked questions

You have any questions? Please contact us. We will have pleasure in helping you. Maybe one of the following frequently asked questions will already solve your problem.



Can end-users purchase directly from you?

We, as a manufacturer, do not have the possibility to supply directly to end-users. Our products are available through distributors all over the world. We shall be very pleased to inform you about the address of our distributor nearest to you. Just let us have a short message.

Why do microscope slides have an expiry date?

Microscope slides are produced from soda lime glass of the 3rd hydrolytic class. This glass is subject to an aging process which affects the quality of the slides. Please consider our recommendations for storage which are included in every carton containing 2.500 pcs.

What is D263?

D263 is a borosilicate glass of the 1st hydrolytic class from which we produce our microscope cover glasses. Following herewith you will find the most important technical properties of this glass:

Refractive index (nd) = 1,5231 (588 nm)

Coefficient of thermal expansion (20-300 °C) = 72x10-7/K

Transformation temperature (Tg) = 557 °C

Which products will be CE-marked, which products not?

"In-vitro-diagnostica" are defined by the legislator to be medical products which, in accordance to the particular purpose determined by the producer of the goods, are used for the in-vitro-determination of specimens from the human body including blood and human tissue donations.

General laboratory products are not considered as in-vitro diagnostica unless, due to their characteristics and in accordance to the particular purpose determined by the producer, they have to be used especially for in-vitro determinations.
In-vitro diagnostica which formerly had to be supplied "officially tested and stamped" within the Federal Republic of Germany will be supplied with CE-mark in the European Union. Capillary tubes for blood specimens, blood diluting pipettes and blood sedimentation pipettes will also be supplied with CE-mark within the European Union.

What do I have to consider when selling CE-marked products?

In accordance to the 98/79/EC Directive of the European Parliament and the Council in-vitro diagnostica must be marketed within the European Union with CE-mark only since December 6, 2003. The Medical Products Law requires the distributor of such products to act as a medical consultant to his customers and notify the manufacturer of any grave incident caused by his products.

An incident is considered as grave if humans have sustained significant damages to their health when using an IVD product. IVD products have to be traceable and, therefore, the products or their packaging have to bear a production lot number, the address of the manufacturer and - when applicable - an expiry date.

IVD products have to be traceable through the whole supply chain from the manufacturer to the end user, because the manufacturer must be able to call back all products of a possibly defective production lot in case this has caused grave incidents. 

You indicate that your blood lancets do have an improved tip. What does that mean?

Our blood lancets are produced with an asymmetric tip. This special shape of the tip makes the insertion into the skin less painful and is the reason for a fast healing of the puncture.

Which part of your volumetric glassware is available as conformity certified?

The following products are available conformity certified: graduated and volumetric pipettes, graduated cylinders, volumetric flasks and burettes acc. to Mohr and Pellet. These products bear the mark "H" which stands for "conformity certified". On request and at an extra charge we can also issue certificates for the graduated cylinders, the volumetric flasks and the burettes.

Which certificates are available for your conformity certified volumetric glassware?

A batch certificate of conformity is supplied together with every box for class AS conformity certified products. On request individual certificates of conformity are available at an extra charge.

Why do capillary tubes have an expiry date?

Over the years the capillary effect and the heparinization (if any) decrease.

What is the difference between epoxy-resin coated slides and teflon-coated slides?

Our epoxy-resin coating adheres on the glass very well and slides with that coating can be produced more cost-saving than slides bearing coatings of fluoropolymer for example "Teflon®" (a trademark of DuPont). Normally the masks of fluoropolymer-coated microscope slides are more hydrophobic than those coated with epoxy-resin.

Does Histofluid have an expiry date?

Histofluid can be stored unlimited if it remains in closed containers. Therefore there's no need for a batch management. Open bottles will allow the escaping of the component xylene and the liquid will dry out. It can, however, be resolved by adding xylene. Due to the xylene contained in Histofluid we recommend to use this mounting medium under an extractor hood only.
