Pierceable and Pre-Slit Microplate Sealing Film

Access individual wells without removing the entire cover. This family compares two distinct constructions: 96-position pre-slit film with cross-shaped access cuts, and pierceable film with adhesive-free well centers.

  • Targeted well access: Useful when tips or probes must enter selected wells through a cover.
  • Pre-slit option: Cross-shaped cuts guide access at designated 96-well positions.
  • Adhesive-free centers option: Keeps the piercing zone different from the adhesive bonding region.

PRODUCT DETAILS

Access individual wells without removing the entire cover. This family compares two distinct constructions: 96-position pre-slit film with cross-shaped access cuts, and pierceable film with adhesive-free well centers.

Product Highlights

  • Targeted well access. Useful when tips or probes must enter selected wells through a cover.
  • Pre-slit option. Cross-shaped cuts guide access at designated 96-well positions.
  • Adhesive-free centers option. Keeps the piercing zone different from the adhesive bonding region.
  • Automation selection. Match alignment, probe dimensions and access motion to the film construction.

Structure and Functional Design

Component Function
Pre-slit film A continuous carrier with intentional plus-shaped cuts over each target well.
Adhesive-free-center film Uses nonadhesive well-center areas; it is not the same structure as pre-cut crosses.
Alignment features Film orientation, well spacing and tab placement must match the actual plate.

Technical Specifications and Selection Guide

Use the configurations below to specify your inquiry. Dimensions and thicknesses are reference configurations, not a guarantee of stock or universal compatibility. The selected grade, usable sealing area, packaging and operating limits will be confirmed in the quotation and product specification.

Construction Nominal thickness Sheet size (mm) Access design
Adhesive-free well centers 85 ± 10 µm 145 × 80; 151 × 80 Pierceable centers; confirm pattern and orientation
96-position pre-slit polyolefin 100 ± 10 µm 137 × 80 Pre-cut cross at each designated well center
Item Selection information
Format Patterned microplate film sheets
Reference pack 100 sheets/box
Positioning Match the complete pattern to the plate drawing
Qualification Tip/probe diameter, insertion force, withdrawal and carryover

Applications

For sample preparation, autosampling and manual or automated liquid-handling methods where individual-well access is required. Qualify the seal with the actual tips, probes, plate and liquid-handling motion.

Application and Compatibility Checklist

  1. Confirm the required construction: pre-slit crosses or adhesive-free piercing centers.
  2. Align the full pattern with the plate before pressing the adhesive contact areas.
  3. Test central and edge positions using the actual instrument. Observe insertion/withdrawal, plate lift, debris and liquid transfer.
  4. After access, assess the remaining cover condition and allowable hold time. Replace or reseal according to the validated workflow.
Selection note: A film returning toward its original shape after tip removal does not prove a liquid-tight or gas-tight reseal. Do not treat pre-slit film as an unpunctured storage barrier.

Product Image Notes

Both photographs show the pre-slit construction during single-tip and multichannel access. They do not illustrate the adhesive-free-center option. Plate and tips not included.

Ordering Information

For a useful quotation, send your plate model or drawing, preferred film construction, sheet size or roll-feed requirements, application conditions, quantity and destination country. For heat-seal products, include the sealer model. If lot-specific quality documents or special packaging are required, list them in the inquiry so they can be checked for the selected grade.

Evaluate a representative sample under your actual workflow before changing a qualified laboratory consumable. A general family description does not replace grade-specific test data.

Frequently Asked Questions

Are pre-slit and adhesive-free-center films identical?

No. Pre-slit film has actual cuts; an adhesive-free-center construction changes where adhesive is present. Order by access structure as well as dimensions.

Does it fit every 96-well plate?

No. Check well spacing, rim geometry, pattern orientation and instrument clearances against your plate drawing.

Can it be pierced repeatedly?

The number of acceptable accesses depends on the exact material, tool and sample workflow. Test for tearing, carryover and loss of coverage.
