Pipettes Suppliers

A pipette is a laboratory tool used to measure and transfer small volumes of liquid. It consists of a long, narrow tube with a bulb at one end and a tapered tip at the other. Pipettes are commonly used in scientific research, medical laboratories, and other settings where precise measurements of liquids are necessary. They come in various sizes and types, including disposable and reusable, and can be manual or electronic.

However, in general, there are several types of pipettes available in Australia, including:

• Volumetric pipettes: These are used for measuring a specific volume of liquid accurately.
• Graduated pipettes: These are used for measuring different volumes of liquid accurately.
• Micropipettes: These are used for measuring very small volumes of liquid accurately.
• Serological pipettes: These are used for measuring and transferring liquid in a laboratory setting.
• Pasteur pipettes: These are used for transferring small amounts of liquid.
• Transfer pipettes: These are used for transferring small amounts of liquid from one container to another.
• Positive displacement pipettes: These are used for measuring viscous liquids or liquids that contain particles.
• Electronic pipettes: These are used for measuring and dispensing precise volumes of liquid using electronic controls.
• Multichannel pipettes: These are used for dispensing multiple samples at once.

Repeater pipettes: These are used for dispensing the same volume of liquid multiple times.

However, the accuracy and precision of a pipette depend on various factors such as the type of pipette, the volume being measured, the calibration of the pipette, and the technique used by the operator. Generally, pipettes are designed to be accurate within a range of ±0.5% to ±5% and precise within a range of ±0.1% to ±1%. It is essential to calibrate and maintain pipettes regularly to ensure accurate and precise measurements.

However, a pipette can have different volume ranges depending on its type and purpose. Some common pipette volume ranges are 0.1 µL to 10 mL for micropipettes, 1 mL to 100 mL for serological pipettes, and 1 mL to 50 mL for volumetric pipettes. The specific volume range of a pipette should be indicated on its label or manual.

However, the cost of a pipette can vary depending on the brand, model, and features. Some pipettes may cost a few hundred dollars, while others can cost over a thousand dollars. It is best to check with laboratory equipment suppliers or manufacturers for current pricing and any available discounts or promotions.

Regular cleaning: Pipettes should be cleaned after each use to prevent contamination. Use a mild detergent and warm water to clean the pipette. Rinse thoroughly with distilled water and dry with a lint-free cloth.

• Calibration: Pipettes should be calibrated regularly to ensure accurate measurements. Calibration should be done by a qualified technician.
• Lubrication: Pipettes should be lubricated regularly to ensure smooth operation. Use a high-quality lubricant recommended by the manufacturer.
• Storage: Pipettes should be stored in a clean, dry place when not in use. Keep them away from direct sunlight and extreme temperatures.

Replacement: Pipettes have a limited lifespan and should be replaced when they show signs of wear and tear or when they no longer meet calibration standards.

To calibrate a pipette, you need to follow these steps:

• Clean the pipette with distilled water and dry it with a lint-free cloth.
• Check the pipette for any damage or wear and tear.
• Select a suitable calibration standard, such as distilled water or a standard solution.
• Set the pipette to the desired volume.
• Dispense the calibration standard into a weighing boat or a volumetric flask.
• Weigh or measure the volume of the calibration standard.
• Compare the measured value to the expected value and calculate the error.
• Adjust the pipette if necessary, using the adjustment knob or screw.
• Repeat the calibration process until the error is within the acceptable range.

Record the calibration results in a logbook or calibration certificate.
