Vacuum aspiration device for 1ml pipette tips

A vacuum waste liquid aspiration device that has been used in the lab for two years, using extended or standard 1ml pipette tips for aspiration. The attached hose has an inner diameter of 6 mm. When not in use, it can be stored on the side wall of a laminar flow hood. It is mainly used to aspirate waste liquid from relatively shallow containers such as culture flasks and culture plates. For aspirating liquid from deeper containers such as culture flasks, it is still better to use a glass pipette. Some students have a lot of strength, and forcefully pushing the tip on can cause the tip to get stuck on the aspirator. Therefore, a small clip was designed to assist in detaching the tip. This rack is most prone to damage under long-term UV exposure. If the habit of attaching tips is good, this small clip can be entirely omitted.
