compliance
The “Compliance” mark indicates that volumetric products conform to the German Federal Weights and Measures Standards Institute (DIN 12600) in terms of tolerance and accuracy. Compliance test methods and certification procedures are defined in DIN 12600 standards. German measurement and calibration procedures are audited at regular intervals by the German Accreditation Body. As a result of inspections, manufacturers may use the accredited conformity mark (DE-M). In order for the manufacturer to apply the maximum “Compliance” mark on products, production processes and measuring tools must fully comply with DIN 12600 standards. INTERLAB meets these requirements and is authorized to apply the “Compliance” mark. The batch certificate indicates that volumetric product batches are tested and controlled within the lot and comply with tolerances. From each production batch, the minimum number of products required by the standard is randomly selected, controlled according to DIN 12600, and certified. The batch certificate includes the production date, average volume value, acceptable deviation value, declared tolerances, and similar measurement data. Batch numbers can be accessed continuously through batch certificates. Batch numbers and relevant certificates can be downloaded from the website. To access the certificate: visit www.interlab.com.tr and enter the “Certificates” section. ► Enter the product code or the batch number on the product body. ► The certificate opens automatically. ► Use the “print option” in the lower left corner for printing.

classification
volume graduation
All are manufactured based on volume (IN) or to deliver (EX). They are classified as Class “B”, “A”, or “AS”. Class “A” and “AS” have identical tolerances and error limits. volumetric products The only difference lies in waiting and delivery times. “S” refers to fast delivery. The difference between Classes A and B is the level of sensitivity in volumetric parameters. Class “A” and “AS” volumetric products are preferred for applications requiring high precision. Volume limit and sensitivity values are always defined according to the relevant ISO and DIN standards.
Due to surface tension of liquids, the curved structure formed is called the meniscus. According to DIN, ISO, and similar standards, volume measurement is performed at the lowest level of the meniscus. In evaluation, the lowest point of the graduation line is taken as reference. In volumetric glassware, the liquid forms a concave meniscus.
For precise and accurate results, the operator’s eye level and the graduation line must be aligned on the same plane.
schelbach stripe
The Schelbach stripe is located on the burette tube. It consists of a blue band in the center and is used for easier observation of the volume graduation.
For more accurate, clearer, and more precise measurements, it is fixed behind the graduation line of burette or pipette tubes. Reflected light ensures sharper visibility of the graduation line. The correct reading point of the volume is where the two lines intersect.
delivery time
Delivery time is the period between the upper starting line and the lower finishing line during liquid transfer. This point is where the tip of the pipette in burettes is located.
waiting time
Waiting time is the period after complete delivery during liquid transfer. After liquid transfer, residual liquid may continue to flow from the burette or pipette wall. For precise volumetric measurements, waiting time must be strictly observed. Especially in pipettes, the last remaining drop accumulated at the tip must be considered in volume measurement.

VOLUMETRIC FLASKS - “glass” - “class A” “conformity certified” - “COATED”
Glass materials used in laboratories carry a potential risk of breakage due to their delicate structure. Even small impacts may cause glass to shatter, crack, and lead to serious safety issues. Especially glass materials containing hazardous chemicals may scatter fragments around when broken. This situation may pose life-threatening risks to personnel. To eliminate these risks, ISOLAB GmbH has developed a flexible and high-strength surface coating polymer that completely covers the outer surface of glass materials, providing safety. The coating adapts to the glass surface, maintains its flexibility, and provides superior resistance to breakage and impacts. The coating offers high transparency, allowing easy observation of the measurement level. It withstands up to 30 minutes at 135°C, washing at 95°C, and autoclaving at 121°C. In case of surface coating damage, glass fragments are prevented from scattering around. It significantly prevents the liquid inside the container from spreading to the external environment, thereby reducing the risk of contact with personnel. Thus, serious injuries that may result from breakage of glassware and other delicate glass surfaces are prevented. This technology not only protects human health but also prevents damage to laboratory equipment and work environment. Surface-coated volumetric flasks must not be exposed directly to flame.
