HPLC/GC Accessories

Vials Rack

Vials Racks are designed for stable storage, handling, and transportation of HPLC and GC sample vials in analytical laboratories. Transparent or colour-coded racks allow quick visual identification of vial type and sample batch, while solid construction ensures a stable standing position during lab workflows.

Acrylic and PP materials resist most solvents, ensuring durability in chemical and analytical environments
Transparent racks allow visual inspection for cleanliness and vial integrity
Colour-coded racks (blue, white) help differentiate vial types and sample batches at a glance
Four diameter sizes match 2 ml, 4 ml, headspace, and 24-400 vials for consistent fit and stability

Comparison

Compared With The Alternatives

Versus Plastic vial boxes with no structure

Vials Racks provide a stable, upright position that prevents tipping and vial breakage during transport or bench use

Versus Opaque plastic racks

Transparent racks allow visual confirmation of vial condition and cleanliness, which is critical in analytical workflows

Versus Single-material racks

Dual material options (acrylic and PP) allow selection based on solvent resistance and visibility needs

Versus Racks without colour coding

Colour-coded racks reduce the risk of sample mix-up when multiple vial types are stored in the same area

Use Guide

How To Use It

Select rack diameter based on vial size: 12.5 mm for 2 ml, 16.5 mm for 4 ml, 22.5 mm for headspace, 28.5 mm for 24-400 vials
Use transparent racks for visual inspection of vial condition and cleanliness
Use colour-coded racks (blue or white) to differentiate sample batches or vial types
Place racks on a flat, stable surface to prevent tipping during handling
Clean racks with mild detergent and rinse thoroughly; avoid abrasive cleaners that may scratch acrylic

Questions Buyers Ask

What is the difference between acrylic and PP vial racks?

Acrylic racks are transparent and suitable for visual inspection; PP racks are more chemical-resistant and available in blue and white for colour coding

Which rack fits a 2 ml vial?

VR02A (acrylic, 12.5 mm diameter) or VR02P (PP, 12 mm diameter) are designed for 2 ml vials

Can I use these racks for headspace vials?

Yes. VR20A (acrylic) and VR20P (PP) are designed for headspace vials with a 22.5 mm diameter

Are the racks compatible with autosamplers?

Yes, the stable construction and consistent diameter ensure proper fit and alignment in autosampler trays

How are the racks packed?

Each rack is packed individually by part number: VR02A, VR04A, VR20A, VR24A (50#), VR20P, VR24P (40#), VB02P (100#)

Can I get these under my own brand?

Yes. The Microlab OEM division offers private-label printing and packing for PP and acrylic vial racks
