Pipette Stand (Horizontal)

Quick Answer: A horizontal pipette stand is a bench rack that supports pipettes lying flat, across notched supports, so the tips never touch the bench. It is used to rest pipettes between measurements during titrations and analysis.

Resting Pipettes Flat Between Measurements

During a titration or a set of dilutions, a pipette is used, set down and picked up again several times. Laid on the bench it rolls, its tip picks up dust and residue, and a long bulb pipette is easily knocked onto the floor. A horizontal stand gives each pipette a cradle above the bench, with the tip held in the air.

Horizontal racks suit long pipettes, which are awkward to stand upright, and they are stable because nothing is held high above the base. They are less suited to drain-drying after washing, because water lies in the stem instead of running out; for that job, stand pipettes tip down in a vertical pipette stand.

The number of positions and the notch sizes are not given in the title and should be checked against the pipettes you use most. Keeping a separate pipette for each solution, and labelling its place on the stand, is a simple way of avoiding cross-contamination.

Care & Handling

• Place pipettes with the tip pointing away from the working area so it is not brushed by sleeves.
• Let each pipette drain into the correct vessel before laying it down; liquid left inside can run towards the top and reach the filler.
• Clean the supports with mild detergent after acid or dye spills.

Specifications

Applications

• Holding volumetric pipettes between aliquots in acid-base and redox titrations
• Keeping graduated pipettes ready during serial dilutions in biology and microbiology practicals
• A clean resting place at each student station, with one labelled pipette per solution
• Holding long pipettes where an upright stand would be unstable or too tall, such as inside a fume cupboard

Why Choose LabEquip

Chemistry teachers and analysts who want pipettes within reach on each bench, rather than at a central store, use horizontal stands at individual workstations. It is part of LabEquip’s chemistry lab equipment range; send notch sizes or quantities through the contact page.

Frequently Asked Questions

What is the difference between a horizontal and a vertical pipette stand?

A horizontal stand holds pipettes lying flat, which is stable and convenient between measurements. A vertical stand holds them upright and tip down, which lets washing water drain out and fits many pipettes into a small area.

Why keep the pipette tip off the bench?

The tip is the part that enters the solution. If it touches the bench it can pick up residues or be chipped, and a damaged tip no longer delivers its calibrated volume.

Can a pipette be stored horizontally with liquid inside?

No. Drain it first. Liquid left in a horizontal pipette can run towards the top end and wet the filler, contaminating both the filler and the next sample.

Is a horizontal stand suitable for bulb pipettes?

Yes, provided the supports take the stem on either side of the bulb. The bulb should sit between the supports rather than resting on one of them.

How should I clean the stand?

Wipe it with water and a mild laboratory detergent, then rinse and dry. Remove dye or indicator stains promptly, and avoid solvents that could attack the plastic.

How many pipettes should one station have?

One for each solution being measured is the usual practice, for example one for the acid and one for the alkali. Labelling each position prevents a pipette being dipped into the wrong solution.
