A laboratory centrifuge is a piece of equipment used to separate components of a mixture based on their density and size. It works by spinning samples at high speeds, which creates a centrifugal force that causes the heavier components to move to the bottom of the tube or container. The lighter components remain at the top or in the supernatant.
Laboratory centrifuges are used in various fields such as biology, chemistry, and medicine. They can be used for DNA extraction, protein purification, cell separation, and blood analysis. They are essential tools in research and diagnostic laboratories.

Carbendazim is a broad-spectrum systemic fungicide widely used to protect fruit trees, vegetables, flowers, and field crops from various fungal diseases. It is available in several formulations, including 25%, 50% wettable powder, and 40% suspension concentrate. Despite its effectiveness, many users are still unsure about the correct application methods. Today, we’ll walk you through how to use Carbendazim properly for different crops.
When it comes to controlling fruit tree diseases, here’s what you need to know:
1. For pear trees, apply 50% wettable powder diluted at 500 times during the budding stage and after flowering. Repeat the spray every 7–10 days for 2–3 applications to effectively prevent pear scab.
2. For apple trees, start spraying with 50% wettable powder diluted at 500–800 times from the early stages of disease occurrence. According to recommendations from pesticide manufacturers, reapply after 7–10 days to help control apple brown spot.
3. For grapevines, begin spraying once the leaves have developed and continue every 10–15 days using 50% wettable powder diluted at 500–1000 times. This treatment is effective against black rot, white rot, and anthracnose.
For vegetable crops, Carbendazim can also be highly effective:
1. At the first sign of disease, spray 50% wettable powder diluted at 800–1000 times. Apply every 7–10 days, and repeat up to 3–5 times to manage tomato early blight, cucumber powdery mildew, and beet brown spot.
2. Before transplanting cucumbers or watermelons, mix 1–1.5 kg of 50% wettable powder with 25–30 kg of fine soil and spread it evenly in planting holes or furrows. During the growing season, apply 50% WP diluted at 1000 times to prevent melon wilt.
The Pesticide Information Network strongly advises all users to follow the recommended dosages strictly. Improper use can lead to phytotoxicity, which may cause crop damage and economic loss. Always read the label carefully and ensure proper mixing and application techniques for the best results.
