HPLC/GC Accessories

Crimper and Decrimper

The Crimper and Decrimper are manual tools made from stainless steel for securing and removing aluminium crimp seals on 11 mm and 20 mm HPLC vials. They are used to ensure consistent seal integrity during sample storage and transport, preventing leaks and contamination. The tools are compatible with vials from Agilent, Waters, Varian and Thermo-Fisher brands, supporting standardised workflows in chromatography laboratories.

Stainless steel construction ensures durability and resistance to corrosion in repeated use
11 mm and 20 mm versions match standard vial sizes used in HPLC and GC workflows
Consistent crimping reduces the risk of seal failure during storage or transport
Decrimper allows safe removal of seals without damaging the vial or cap

Applications And Buyers

Application Scenarios

Securing aluminium crimp seals on HPLC vials after sample preparation
Preparing vials for long-term storage or shipping where seal integrity is critical
Removing crimp seals from vials during method transfer or re-analysis
Maintaining consistent seal quality across multiple analysts in a shared lab
Supporting routine maintenance of autosampler vials in high-throughput environments

Who It Is For

HPLC and GC laboratories that use crimp-sealed vials for sample storage
QC labs requiring repeatable seal performance across batches
Contract testing labs handling multiple client samples with strict integrity requirements
Lab managers standardising on a single tool for crimping and decrimping across instruments
OEM partners needing reliable, consistent tools for vial sealing in packaged systems

Problems It Solves

Inconsistent crimping leading to seal leaks during storage or transport
Damaged vial necks or caps when using improper tools for crimp removal
Cross-contamination from loose or poorly sealed vials in autosamplers
Inability to remove seals without damaging the vial or cap
Lack of compatibility between crimping tools and major instrument brands

Comparison

Compared With The Alternatives

Versus Plastic crimping tools

Stainless steel construction resists wear and maintains shape over repeated use, unlike plastic tools that can deform under pressure

Versus Automated crimping systems

Manual tools are lower cost and require no setup or power, suitable for low-volume or portable lab use

Versus Generic crimping pliers

Designed specifically for 11 mm and 20 mm HPLC vials, ensuring correct seal alignment and avoiding vial damage

Versus No dedicated decrimper

DCR20 allows safe removal of crimp seals without damaging the vial or cap, reducing waste and risk of contamination

Use Guide

How To Use It

Select the correct tool: CR11 for 11 mm vials, CR20 or DCR20 for 20 mm vials
Place the vial cap into the tool with the crimped edge aligned
Apply steady pressure to crimp the seal securely, ensuring full contact with the vial neck
For decrimping, position the DCR20 tool around the 20 mm cap and apply pressure to release the seal
Inspect the vial and cap after crimping or decrimping for damage or deformation
Clean tools after use to prevent residue buildup that could affect seal integrity
