Our test plates exhibit finest workmanship, ease of inscription and uniform growth treatment. The lid has an air-venting system and guarantees a controlled gas exchange. The sloped edge of the lid ensures that it can be placed in one position only on the test plate. The yellow inscription areas support this positioning inasmuch that yellow goes to yellow!
The alphanumeric well coordination is inlaid in black and can be clearly recognized at practical distances. |
