Partially Autoclavable Single-Channel Fixed-Volume Pipette

Product Highlights

• 12 fixed-volume options: 5–5,000 µL across separate instruments.
• Dedicated nominal volume: a clear choice for repeated transfers without routine volume adjustment.
• Partially autoclavable: approved lower components only; the handle must not be autoclaved.
• Bench-friendly controls: thumb plunger, finger support and a tip-ejection control.
• OEM enquiries: discuss range selection, tip fit, branding and packaging with Puretest.

Pipette Structure and Functional Design

Technical Overview

Fixed-Volume Options

Options are listed from small to large. Each row represents an individual instrument model; all volume values are in microliters (µL).

Images show representative instruments within this design family. Nozzle dimensions and markings can vary with the selected volume. Confirm the exact range and configuration on your quotation.

Applications and Workflow Fit

Repetitive reagent addition, routine aliquoting, standardized sample preparation, training and dedicated fixed-volume laboratory tasks.

Choose this family for a repeated nominal volume when component-level autoclaving meets your workflow requirements.

For a laboratory set, combine instruments around the volumes you actually use. A low-volume transfer, a routine reagent addition and a milliliter-scale buffer step may call for different ranges and different tips.

How to Select the Right Pipette

1. Choose the exact nominal volume used by your procedure; a fixed-volume instrument is not an adjustable range model.
2. Select tips by both capacity and physical fit. Larger-volume instruments may require a different tip format from standard microliter models.
3. Choose partial autoclavability only when lower-component treatment meets your procedure. Select a fully autoclavable family if the complete instrument must be treated.
4. For purchasing or qualification, request the model-specific increment and calibration data for the exact supplied configuration and your required working volumes.

Handling, Cleaning and Maintenance

• Inspect the instrument and fit clean, correctly matched tips before use. For multichannel work, check seating and liquid levels at every position.
• Use a consistent plunger speed, immersion depth and dispensing technique appropriate to the liquid and the supplied operating instructions.
• Prevent liquid from entering the handle. Store the instrument upright when not in use and replace tips between samples as your procedure requires.
• Separate only the components designated in the supplied instructions for autoclaving. Keep the upper handle out of the autoclave and allow treated components to cool and dry.
• Inspect seals and moving parts as part of routine maintenance. Arrange a performance check after servicing, an impact or suspected leakage.

Frequently Asked Questions

Can I change the dispensing volume?

No. Each fixed-volume model is dedicated to its listed nominal volume. Choose a different fixed model or an adjustable pipette if your method requires other volumes.

Can the complete instrument be autoclaved?

No. Only the designated lower components are intended for autoclaving. The upper handle is not included in the autoclaving scope.

Will every universal tip fit?

Not necessarily. Capacity, cone geometry and sealing must match. Ask for a tip recommendation and evaluate the chosen pipette-tip combination before a larger order.

Where can I find accuracy and precision data?

Request the calibration or performance document for the exact supplied model and volume range. Results and acceptance criteria should correspond to that configuration, its test volumes and the tips used.

Can Puretest support private-label enquiries?

Send your required ranges, quantities, intended market and branding or packaging requirements. Puretest can review the proposed configuration and discuss samples and quotation details before you commit to an order.
