Volumetric Pipette 5ml

Product Code : SCL-LG-11995

The volumetric pipette from Science Lab Supplies is a borosilicate-glass laboratory pipette used for fixed nominal-volume liquid transfer in 5, 10, 20, 25 and 50 mL capacities. Permanent amber-stain markings are diffused into the glass surface for visibility and durability, while the sturdy construction supports repeated laboratory handling.

Product Description

This borosilicate glass volumetric pipette is designed for laboratory procedures that require transfer of a selected nominal liquid volume. Five available capacities allow users to choose the size appropriate to the method: 5 mL, 10 mL, 20 mL, 25 mL or 50 mL. The source specifies that these pipettes are not graduated to the tip.

Permanent amber-stain markings are diffused into the glass surface rather than applied as temporary external labels. For broader quantitative workflows, the pipette can be used alongside appropriate receiving vessels such as a laboratory volumetric flask, subject to the analytical method and verified calibration requirements.

Key Features

• Five selectable capacities: available in 5 mL, 10 mL, 20 mL, 25 mL and 50 mL for different fixed-volume liquid-transfer requirements.
• Borosilicate-glass construction: provides a laboratory glass format suitable for repeated routine handling and cleaning.
• Permanent amber-stain markings: markings are diffused into the glass surface for improved visibility and durability.
• Not graduated to the tip: the source specifically distinguishes this product from pipettes carrying graduations extending to the tip.
• Sturdy construction: designed for extended laboratory use when handled and maintained correctly.
• Capacity-specific selection: laboratories can match the nominal pipette volume to the procedure rather than relying on one multi-graduated instrument.
• Related variable-volume option available: procedures requiring multiple graduated volume readings can instead consider graduated laboratory pipettes.

Technical Specifications

• Additional accessories

Applications / Uses

A volumetric pipette is used where a laboratory procedure requires transfer of a selected nominal volume of liquid, subject to the instrument's verified accuracy class, tolerance and the applicable laboratory method.

• Quantitative chemistry procedures requiring capacity-specific liquid transfer.
• Preparation and dilution workflows involving a volumetric flask.
• Analytical procedures where a measured aliquot is transferred before titration using suitable glassware burettes.
• Solution preparation and liquid-transfer procedures involving laboratory glass beakers.
• Chemistry practical work in schools, colleges, universities and instructional laboratories.
• Routine analytical and research workflows where the required tolerance is compatible with the verified specification of the selected pipette.

How to Use the Volumetric Pipette

Use a volumetric pipette with an appropriate pipette filler and follow the laboratory's approved method for liquid uptake, meniscus adjustment, delivery and drainage.

1. Select the nominal capacity required by the analytical or educational procedure.
2. Inspect the glass pipette for chips, cracks, contamination or damaged markings before use.
3. Clean the pipette and, where the method requires it, condition or rinse it with the solution being transferred.
4. Attach a compatible mechanical pipette filler. Never pipette by mouth.
5. Draw the liquid above the applicable volume mark without allowing liquid to enter the filler.
6. Hold the pipette vertically and adjust the liquid meniscus to the relevant mark at eye level.
7. Transfer the liquid to the receiving vessel according to the laboratory method and verified pipette delivery specification.

Safety and handling note: Wear appropriate personal protective equipment, never use damaged glassware, never pipette by mouth and confirm chemical compatibility before transferring hazardous, corrosive or reactive liquids. Do not assume a blow-out or drain-time procedure unless it is supported by the verified specification for this exact pipette.

Care & Maintenance

Proper cleaning, inspection and protected storage help preserve the condition of the glass surface and permanent amber markings.

• Clean promptly after use with a method compatible with the transferred liquid and laboratory SOP.
• Avoid abrasive tools or aggressive treatment that could damage the glass surface or impair marking visibility.
• Inspect regularly for chips, cracks and contamination before reuse.
• Store securely to reduce impact and breakage. A separate pipette holder may be considered after confirming dimensional compatibility with the selected glass pipette.

Frequently Asked Questions

What is a volumetric pipette used for?

A volumetric pipette is used to transfer a selected nominal volume of liquid in laboratory procedures. This product is available in 5 mL, 10 mL, 20 mL, 25 mL and 50 mL capacities, allowing the user to select a size appropriate to the method.

What capacities are available for this volumetric pipette?

The verified source lists five capacities: 5 mL, 10 mL, 20 mL, 25 mL and 50 mL. No additional capacities were stated on the supplied source page.

Is this volumetric pipette made from borosilicate glass?

Yes. The source specifically identifies the product as a borosilicate glass volumetric pipette and states that it has permanent amber-stain markings diffused into the glass surface.

Is the volumetric pipette graduated to the tip?

No. The supplied source explicitly states that these pipettes are not graduated to the tip. Users needing a scale for measuring different volumes may instead evaluate a graduated pipette suited to the required method.

Can this volumetric pipette be used for titration work?

Yes, a volumetric pipette can be used to transfer a selected liquid aliquot during a titration workflow, provided the capacity, accuracy class and tolerance meet the analytical method. The exact accuracy class and tolerance of this product are.

Does this volumetric pipette comply with ISO 648 or have a Class A or Class B accuracy rating?

ISO 648:2008 is the relevant international standard for single-volume laboratory pipettes, but compliance of this exact product is. The supplied source does not state a Class A or Class B accuracy designation, tolerance or individual calibration certificate.
