The container is made of PP and has a double structure. The outer part is flared at the bottom for stability. The inner part is designed to lower the center of the bottom, allowing it to draw up nearly the entire amount of liquid. The cap of the container is set with each dropper.

• Plastic utensils and containers

It is used with a suction filtration funnel and consists of 6 combinations, allowing it to be adjusted to the size of the counterpart. Since there are 6 types of sizes and colors (in the case of color), it can be used with all types of bottles with different diameters of funnels and glass filters, etc.

We offer a wide variety of sizes and accept small orders as well.

• Rubber

Due to the low gas permeability and high recovery force after the withdrawal of the injection needle, there is an advantage of being able to use the injection needle multiple times when used with a vial. The part that is in contact with the bottle is made longer.

• Rubber

The design makes it easy to connect the tubes, and there are various sizes available. It is excellent in chemical and heat resistance.

• Pipe Fittings

Due to its excellent transparency, fluid inspection can be performed smoothly. It is lightweight and easy to use, and installation with fittings is also straightforward. Features: - The inclusion of vertical threads minimizes elongation under pressure. - There is no separation between layers. - The burst pressure is designed to be 4 to 5 times that of normal pressure. - In particular, the elongation in the case of temperature rise is less than half compared to other products.

The rubber tubes used to connect to experimental equipment typically have an inner diameter of 4mm to 6mm, but when connected to laboratory faucets, they require finger strength to attach and can come loose afterward, and the rubber tends to age quickly, which presents some drawbacks. Additionally, there was a challenge when connecting pressure-resistant rubber tubes with a small inner diameter due to significant differences in diameter within the equipment. However, the connector is a convenient solution that addresses these issues. It is particularly suitable for vinyl tubes.

• Other laboratory equipment and containers

It does not dissolve in alcohol, ketones, or glycols, but it dissolves in aliphatic, aromatic, ether, and chlorine-based solvents. Additionally, it is stable against most mineral oil-based and plant-based oils, as well as many organic chemicals and gases. Features: - Highly refined to remove volatile components, achieving a high vacuum of 10^-6 mmHg. - Usable over a wide temperature range (approximately -40 to 204°C). In the absence of oxygen, it can be used up to 260°C. - Chemically stable, it is hardly oxidized even at high temperatures, has excellent oil and chemical resistance, and does not dissolve in water. - It has excellent insulating properties. - It has minimal impact on human health.

• Lubricants

This product is newly designed in a clip shape and can be easily attached to beakers and the like. The tube holder (large) holds tubes with an outer diameter of 14mm or less. The (small) holder is for tubes with a diameter of 10mm or less. Thin tubes can be clamped in the V-shaped part. When using a stick thermometer, insert the thermometer facing the opposite side and adjust the height as needed.

• Plastic utensils and containers

There are five colors including natural, so you can use them for different purposes.

This is a very convenient product that can clean and stir with just one item. (The part that is not rubber at the tip can be used as a stirring rod.) It is a tool for appropriately cleaning up residues in containers such as beakers, but it has been designed with a spherical end on the opposite side to serve the purpose of stirring.

Multi W tubing is a soft polyethylene tube with a polyolefin liner arranged inside a special elastomer. The liner part is heat-fused, so it will not peel off. However, please avoid tightening it too much with pinch cocks or similar devices.

It is a plastic container used in experiments and similar applications. It is used for stirring and mixing liquids.

• Plastic utensils and containers

Features: The spout forms a semicircle downward, allowing liquids to flow relatively easily, making it designed to easily discharge high-viscosity substances and similar materials.

• Plastic utensils and containers

It is very convenient when refilling, and it significantly improves work efficiency.

- Characteristics 1. We offer three colors: red, blue, and yellow, making it easy to confirm the division of lines. Additionally, each color is transparent, allowing for fluid visibility. 2. The tube has a double structure with an inner and outer layer. The inner layer uses a particularly excellent elastomer, ensuring satisfaction with chemical resistance, oil resistance, and cold and heat resistance. It also complies with PL standards (JHP Y-3189), making it safe for food applications. 3. We use non-migratory materials, so it is safe to use fittings made of ABS and other materials.

• tube

Since it is a disposable type, it can always be used in a clean state. There are round and bellows-shaped head types, as well as round and square scale types, along with other types with a capacity of 0.5 cc and approximately 4 cc, offering a wide variety. For more details, please contact our company.

This product features a silicone sponge tube that excels in high lubricity and wear resistance. A special lubricating resin is applied as a thin film on the surface of the hose (Slip-Up Coat), providing durability against solvents, acids, and alkalis. When bonded to existing pipes using silicone adhesive, it dries within a day and serves as a protective tube.

- The Calorex 15φ and 30φ can be installed on a 100L reaction vessel equipped with a 1.4 square meter cooler. It prevents solvent vapors from creeping up, increasing cooling efficiency by 30%. The use of Calorex is not limited to glass apparatus; it can also be used with iron pipes, steel, or plastic containers, just like glass. It can be safely and easily handled in factories and laboratories, and is safe against explosions. - Regarding the wrapping method, it is used by wrapping it around the device, and the wrapping can be done loosely while maintaining spacing between the tubes or tightly. If wrapping around a vertical device, connect it so that the liquid flows from the bottom to the top of the device, with the outlet at the top. When using steam, it should be the opposite, flowing from the top to the bottom of the device. When attaching the flat surface of the tube to a round container, use heat-resistant adhesive tape to secure the tube. If the tube is to be used for heating, please stretch the wrapped tube slightly after reaching the desired temperature. It can be connected regardless of the type of nozzle or nipple at the water or steam supply inlet.

- It meets similar conditions as the multi-ultra hose, but the outer covering resin is flexible, allowing for good operational handling. - It has flexibility due to the absence of reinforcing threads. The pressure resistance is detailed in the catalog, so please review it before use. - Fluorine tubes have a weakness to bending, but by coating them with resin, a good bending angle can be achieved.

Material: Polyethylene Although the cap and inner stopper are integrated, the inner stopper does not turn when the cap is twisted. There is no wear on the bottle or inner stopper due to the adhesion of crystalline, powdered, paste-like substances, or viscous liquids. Dirt can be separated and washed.

- The inner surface is made of fluororesin, so it is not affected by most solvents, including strong acids and strong alkalis. - It is a non-extractable hose, so it does not alter the inner fluid and maintains its purity. - It is a non-adhesive hose, which provides excellent pressure resistance. - It demonstrates strength even after repeated bending.
