HPLC CONSUMABLES & HARDWARE
HPLC Column Packing Material
Silica-based HPLC packing materials for analytical, flash and preparative separations. Select particle size, pore size and bonded phase, then request bulk or sample quantities.
Silica stationary phases
Analytical to prep grades
Multiple bonded phases
Bulk lots available
Silica Packing for Liquid Chromatography
Silica gel remains the most widely used substrate for liquid-chromatography stationary phases. Physical properties such as particle size, pore size and bonded chemistry determine efficiency, back-pressure and selectivity.
Empty column tubes are listed separately on empty HPLC column hardware. Packed USHD columns are under HPLC columns.
Packing Material Options
Ranges below are taken from the previous packing-material page. Confirm the exact lot and chemistry on RFQ.
Average Particle Size
Listed sizes include 1.8 μm, 2 μm, 3 μm, 5 μm, 10 μm, 20 μm, 30 μm and larger particles.
Bonded Phase
Listed chemistries include C18, C8, C4, C18-BIO, C18-T, C18-AQ, Phenyl, NH2, CN, Diol and SiL.
Sealing Assembly
Standard seal / un-sealed options for wholesale and bulk orders.
Average Pore Size
Listed pores include 70 Å, 100 Å, 120 Å, 200 Å and 300 Å (page copy used μm notation historically).
Grade Families
Grade descriptions from the previous page.
| Grade | Use |
|---|---|
| HPLC analytical grades | High-efficiency analytical HPLC / UHPLC separations |
| Semi-preparative & flash grades | Flash and semi-prep cartridge / column separations |
| Preparative & flash grades | Preparative HPLC packing with scale-up focus |
| Industrial LC grades | Larger-scale purification in chemical and related industries |
Selection Notes
- Start from analyte polarity and required efficiency, then pick particle and pore size.
- Match bonded phase (for example C18 vs NH2 vs SiL) to the separation mode.
- Ask for lot consistency when methods must transfer from lab to process scale.
- Request bulk quantity and destination country with the RFQ.

FAQ
What should purchasing include in a packing-material RFQ?
Bonded phase, particle size, pore size, quantity (g or kg), grade (analytical / flash / prep), destination country and any lot-consistency requirement. Name and work email are enough to start.
What is the MOQ for bulk silica packing?
MOQ varies by phase and particle size. Lab packs and larger bulk lots are both available — send your target quantity and we will confirm MOQ and tier pricing.
Can you supply lot-matched material for method transfer?
Yes. Tell us if you need the same lot for method validation and scale-up, or ongoing lot-to-lot consistency for production purchasing.
Do you offer COA and particle-size / pore-size data with shipments?
Certificate of analysis and key physical data can be provided with commercial lots. List the QC documents your receiving lab requires on the RFQ.
How do I choose analytical vs flash vs preparative grades?
Match the grade to the process scale and back-pressure budget. Analytical grades target high efficiency; flash / prep grades support larger loadings. Send your current method if you need a recommendation.
Can you match an existing commercial packing brand?
Send the brand, catalog number or a current column specification. We will advise on phase, particle and pore options for a commercial substitute where feasible.
What lead time applies to bulk orders?
Lead time depends on phase, quantity and whether the lot is in stock. Include your required ship date so procurement can plan around production and freight.
Do you sell empty tubes separately from packing?
Yes. Empty HPLC column hardware is listed on the empty HPLC column page. Packed USHD columns are under HPLC columns.
Which Incoterms and payment terms are available?
Terms are confirmed on the proforma (for example T/T with EXW / FOB / CIF). Share destination port and preferred freight mode with your RFQ.
Can we request a small evaluation sample before bulk purchase?
Evaluation quantities are often available for standard phases. Ask for sample size, price and air shipping in the quote form before placing a bulk PO.
How is bulk packing packaged for international shipping?
Material is sealed and packed for moisture protection and export handling. Custom labels or purchase-order references can be added for warehouse intake.
Who issues the commercial quotation and PI?
Submit the form on this page or email [email protected]. We will return pricing, lead time and packing details for purchasing approval.
Need a phase and particle size?
Request Packing Material Pricing
Name, email and message are enough. Include phase, particle size, pore size and quantity if known.
