For adjusting the proper volume rotate the volume adjustment dial present at the top of the micropipette. It can be rotated right or left to decrease or increase the volume. The volume that is going to be measured by micropipette is shown on the digital layout. Adjustable micropipette is sturdily designed with different volumes and sizes. It is easy to use, highly accurate and uses standard micropipette tips. The volume is easily selected by twisting the top. The lightweight design and tip ejector makes operation fast & easy. ADJUSTABLE VOLUME: Covering a volume range of 0.5ul to 10ul, increment with 5ul, our micro pipette is more accurate volume setting with digit display. Simply rotate the piston button to select the desired volume.

How to Use a Micropipettor

The accurate use of the micropipettor requires instruction and practice. Practice using the push-button: • The first stopis used for picking up the liquid. • The second stopis used for dispensing. • Place a tip firmly on the end of the micropipettor. • Practice picking up various volumes of liquid. How to Use a Micropipette Sample Delivery with Variable Automatic Micropipettes: The micropipette is used to transfer small amounts (< 1 ml) of liquids. The scales on micropipettes are in microliters (1000 !l = 1 ml). The brand of micropipettes we will be using is made by Rainin and called a "Pipetman".


Variable Micropipette User Instructions

You will use a variable micropipette to prepare seven different dye mixtures in the wells of a microtiter plate. You will then dispense 5 µl of each diluted dye solution onto a pipet card in triplicate. The variable micropipettes are designed for general laboratory use. Micropipettes can be used for measurement and transfer of aqueous solution, acids, bases and enzyme assay applications. These variable volume pipettes cover the range from 0.1 µL to 5 mL in 7 models. The variable micropipettes operate utilizing the air cushion principle, i.e. the aspirated liquid has no contact with the shaft or plunger of the pipette. Liquid is aspirated into disposable tips put on the pipettes. Micropipettes are equipped with a four-digit counter displaying the set volume, and the aspirated volume is set by means of the adjustment knob. The pipette design allows the user to lock the volume setting.

Volume Setting - Good Pipetting Technique

When setting the micrometer on a pipette, always "dial down" to the desired volume. By doing do, you ensure better accuracy by reducing the effects of mechanical backlash or slippage within the micrometer's gears. Topics relevant to life science researchers or anyone using pipettes regularly: Understand the array of pipettes and liquid handling instruments and options available; Know how to optimize your pipetting workflow; Gain the range of pipetting skills necessary to produce reliable data; Appreciate how pipetting ergonomics can influence data production and your own well being; Recognize the risk associated with out-of-calibration pipettes and the role of routine pipette checks vs. professional pipette service.

Quick Volume Adjustment Pipette

Unlike traditional pipettes which utilize a single rotating plunger to set volumes, the Quick Volume Adjustment Pipette features three adjustable dials for setting each individual volume digit. Simply depress and twist the plunger to unlock the volume dials. Once unlocked, freely adjust the three dials to rapidly set the desired volume. This revolutionary approach allows users to set volumes more than ten times faster. Available in single, eight and twelve channel formats, covering a volume range of 0.2 – 5,000 µl, the ultra-lightweight, well balanced design of the Quick Volume Adjustment Pipette enhances productivity and comfort even during prolonged pipetting sessions.

FAQ Of Micropipette

How do you adjust the volume on a micropipette?

On the body of the micropipette is a small vertical window with three numbers. These numbers, read from the top down, tells the user how much volume the micropipette is currently set at. To change the numbers, grasp the black dial or plunger and gently twist. The numbers will then change.

What is variable volume micropipette?

Variable Volume Micropipettes feature built in tip ejectors and autoclavable tip cones. Offered in nine volume ranges. Each pipette is individually calibrated according to ISO 8655 standards. They work on a click stop digital system and are easy to calibrate and maintain.

What is an adjustable micropipette?

Adjustable Micropipette: It is easy to use, highly accurate and uses standard micropipette tips. The volume is easily selected by twisting the top. The lightweight design and tip ejector makes operation fast & easy.


What does do not adjust the volume outside the volume range of a micropipette?

NEVER turn the indicator dial beyond the upper or lower volume limits of the micropipette! This could damage the piston. distribution, ~2/3 of measurements will fall within one standard deviation of the average or mean (x), and 95% of measurements will fall within two standard deviations of the mean.

When adjusting the volume on a micropipette why should you not go above the maximum volume?

NEVER turn the indicator dial beyond the upper or lower volume limits of the micropipette! This could damage the piston. Micropipettes work by air displacement. The operator depresses a plunger that moves an internal piston to one of two different positions.
