The Iwaki PA K-PIPET Komagome Glass Pipette is a Japanese-style glass pipette with a bulged reservoir that holds liquid and a graduated scale along its stem. It is used with a rubber suction bulb to draw up liquid and dispense it drop by drop in a controlled way. In the laboratory, the Komagome pipette is a practical tool for transferring liquids when the volume does not need high volumetric accuracy. Typical tasks include adding reagents, moving solutions between containers and dispensing indicator drops during routine work.
Laboratories choose this pipette because it combines the convenience of a dropping pipette with a graduated scale that helps users estimate volume. The bulged reservoir stops liquid from flowing straight into the rubber bulb, which reduces both contamination and damage to the rubber. Iwaki's glass resists a wide range of chemicals, is easy to clean and can be reused. This makes it more economical than disposable pipettes for routine use. The pipette comes in several sizes, so users can choose the capacity that best fits their working volume.
In Indonesia, the Komagome pipette is a familiar item in school laboratories, university teaching and research laboratories, clinical laboratories and industrial quality control laboratories. Its simple operation suits student practical sessions, where learners are first introduced to liquid handling. Its reusable glass body also suits busy routine laboratories that repeat the same transfers every day. Lab staff can pair it with a matching rubber bulb, clean it between uses and keep it in service for a long time.
- Reagent addition: the bulb gives fine control over how much liquid comes out, so reagents can be added gradually to a reaction or sample without overshooting.
- Solution transfer between containers: the bulged reservoir holds a useful amount of liquid, so solutions can be moved from one vessel to another quickly and with little spillage.
- Indicator dispensing: drop-by-drop release makes the pipette well suited to adding indicator solutions before or during titrations and simple qualitative tests.
- Approximate volume estimation: the graduated scale on the stem gives a quick reading of the drawn volume when a task does not require volumetric precision.
- Teaching and practical sessions: the simple design and reusable glass body make it a practical, durable choice for introducing students to basic liquid-handling technique.

Store Komagome pipettes clean and fully dry in a pipette rack, drawer organizer or closed cabinet where they are protected from dust and impact. Do not let liquid enter the rubber bulb. Draw only to the reservoir and keep the pipette upright while it contains liquid. Rinse the pipette promptly after use with a suitable cleaning agent, then rinse it with purified water and let it dry before storing it. Inspect the glass for chips or cracks before each use, and replace the rubber bulb if it hardens or cracks. Handle glassware carefully and follow standard laboratory safety practice, including wearing suitable personal protective equipment when working with hazardous liquids.
