Burette class B, black graduation, straight valve tap

Burettes are calibrated devices for measuring volumes with graduation and sharp NS male at the bottom and are used to quantitatively measure smaller amounts of liquid in titration in the chemical laboratory.

Adjusted burettes "EX" (by pouring), meaning the amount of liquid poured corresponds to the printed volume.

Clases:

Class B (graduation to short strokes): according to DIN and ISO standards, volume tolerances are twice those of class AS.

Class AS (fast emptying):.



 "A" means maximum accuracy, "S" means quick emptying

Class AS certification of conformity (quick emptying): 



compliance (according to DIN 12 600) means: conformity of a device with the approval standard for the regulated sector according to the German contrast standard and that it meets the requirements of the contrast standard. With the printed label 'H' we certify the device's compliance with the standard. A batch certificate is included in the packaging. We issue individual certificates upon request.
