Safely and accurately collect, transfer, measure, or dispense small amounts of liquid in the lab using sterile pipets of different capacities. Ensure smooth workflows and consistent results with a variety of disposable and reusable options. Staples® stocks a range of high-quality pipets and pipettors as well as other labware and consumables for use in various contexts like labs in schools, hospitals, corporate, and research institutions.

Types of Pipets
These handy items can either measure, transfer, or do both. Dropping, transfer, and volumetric options are all suitable for moving fluids from one location or piece of equipment to another. Choose the wide bore types to hold viscous fluids or liquids that contain small particles. Measuring and serological pipets are graduated to measure the liquid being aspirated or dispensed. They are transparent for easy reading.

Sterile Pipets for Fixed Amounts of Liquid
Options that can only take fixed quantities of liquids have moving parts and are operable mechanically or electronically. Use them to dispense preprogrammed amounts and achieve accuracy even at low capacities. Some feature ambidextrous grips for convenient universal use.

Pipet Capacities
Short options measure 50 millimeters, while extended ones span 600 millimeters. Some can handle as much as 100 milliliters, but micropipettes have a capacity of as little as 1 milliliter. These are accurate for measuring and transferring small volumes. Transfer pipets with higher capacities from 50 milliliters to 100 milliliters are useful for larger amounts of liquid.

Choosing the Pipet and Pipettor Material
Glass models are ideal for handling corrosive chemicals. Thermal-resistant glass can transfer and measure liquids even at low or high temperatures. Glass also retains transparency for longer, so most are graduated to allow visual scrutiny of volumes.

Plastics are sturdy and do not break easily; this makes them the material of choice for many because they can withstand friction. Some are transparent for measurement, and opaque options are suitable for transfers.

Can You Sterilize Pipets and Pipettors?
If they are repeatedly used to conduct experiments that demand sterile equipment, autoclavable units are needed. Autoclaving uses heat to sterilize items, so pipets must be able to withstand this treatment. Disposable pipets reduce the risk of cross contamination but cannot be sterilized and should be thrown away in an appropriate container when used.

What Kinds of Pipets and Pipettors Are There?
Air displacement pipets use pistons to displace air and then aspirates liquid equal to the volume of the ejected air. These options are suitable for aqueous and biological fluids. When aspirating biological liquids, use filter tips to ensure purity. Positive displacement options use a syringe mechanism to aspirate liquids. They are useful for foamy, viscous, volatile, and corrosive liquids.

How Do You Operate Pipets and Pipettors?
Some operate electronically, and others use syringe or rubber mechanisms to draw liquid. Choose the mechanized type to achieve uniformity even where different users aspirate the same reagent. Single-channel options dispense liquid into single receptacles such as centrifuge tubes and test tubes. Multi-channel devices can allot multiple samples of reagents into microplates quickly.

Can You Buy Pipets and Pipettors in Bulk?
Yes. Ensure smooth workflows by choosing packs that contain over 500 pieces to maximize performance and reduce operating costs. Packages that come in assorted colors also help arrange and differentiate pipets and pipettors.
