Pipettes & Micropipettes Suppliers

A pipette is a laboratory tool used to measure and transfer small volumes of liquid accurately. It is commonly used in scientific research, medical laboratories, and other industries that require precise measurements of liquids. Pipettes come in different types and sizes, including micropipettes, serological pipettes, and volumetric pipettes. They are essential for conducting experiments and tests that require precise measurements of liquids.

However, generally, there are several types of pipettes available, including air-displacement pipettes, positive-displacement pipettes, and electronic pipettes. Air-displacement pipettes are the most common and use air pressure to dispense liquid, while positive-displacement pipettes use a piston to dispense liquid. Electronic pipettes use a motor to dispense liquid and offer more precise and accurate measurements. There are also single-channel and multi-channel pipettes available, with the latter allowing for simultaneous dispensing of multiple samples.

Choosing the right pipette for your application involves considering factors such as the volume range, accuracy and precision required, type of liquid being pipetted, and ergonomic features. It is important to also consider the brand reputation and availability of calibration and maintenance services. It is recommended to consult with experts or conduct thorough research before making a purchase.

The accuracy and precision of pipettes depend on various factors such as the type of pipette, the volume being measured, and the technique used by the operator. Generally, high-quality pipettes can achieve accuracy and precision within ±0.5% and ±0.1%, respectively. However, the accuracy and precision can be affected by factors such as temperature, humidity, and the viscosity of the liquid being measured. Regular calibration and maintenance of pipettes are essential to ensure accurate and precise measurements.

Manual pipettes require the user to physically operate the plunger to aspirate and dispense liquid, while electronic pipettes use a motorized mechanism to perform these tasks. Electronic pipettes also often have additional features such as programmable settings and digital displays for increased accuracy and precision.

To calibrate and maintain your pipettes, follow these steps:

• Clean the pipette regularly with a mild detergent and water.
• Check the pipette for any damage or wear and tear, such as cracks or chips.
• Calibrate the pipette using a calibration tool, such as a balance or a gravimetric method.
• Adjust the pipette if necessary, according to the calibration results.
• Lubricate the pipette regularly with a silicone or mineral oil.
• Store the pipette in a clean and dry environment, away from direct sunlight or heat sources.
• Use the pipette according to the manufacturer's instructions and recommended volumes.
• Replace any worn or damaged parts, such as the O-rings or seals, as needed.

By following these steps, you can ensure that your pipettes are accurate and reliable for your laboratory work.

Common pipette accessories and consumables include pipette tips, calibration tools, pipette stands, pipette controllers, and pipette fillers. Pipette tips are disposable and come in various sizes and materials, such as plastic or filtered tips. Calibration tools are used to ensure accurate pipetting volumes, and pipette stands are used to hold pipettes when not in use. Pipette controllers and fillers are used to aid in pipetting by providing a controlled and ergonomic grip on the pipette. Other accessories may include pipette racks, pipette holders, and pipette sterilizers.

However, the price range for pipettes in Australia can vary depending on the brand, type, and quality. Generally, basic pipettes can range from $10 to $50, while more advanced models can cost up to several hundred dollars. It is recommended to check with local suppliers or online retailers for current pricing information.

It is recommended to check with the manufacturer or supplier of the pipettes for specific details on their warranty and return policies.
