Consumables for reliable chromatography workflows
Chromatography performance depends not only on the instrument and method, but also on the consumables that contact the sample and mobile phase. Lotus Corporation supports GC and HPLC laboratories with vials, closures, septa, syringes, tubing, ferrules, lamps, filters, columns and related accessories.
Small dimensional or material differences can cause leaks, adsorption, contamination, evaporation or poor autosampler performance. To avoid mismatches, share the instrument model, current manufacturer code and complete dimensions wherever possible.
Consumables and accessories
- Autosampler vials, inserts and storage vials in relevant sizes and glass types.
- Crimp, snap and screw caps with application-appropriate septa.
- PTFE, silicone and composite septa selected for solvent compatibility and temperature.
- Syringes, syringe filters and sample-preparation accessories.
- HPLC and GC columns, guard products and related fittings.
- PEEK, stainless-steel and application-specific tubing, unions and ferrules.
- Deuterium lamps and other selected instrument spares or accessories.
- Filters and solvent-handling products for mobile-phase preparation.
How to avoid an incorrect match
For vials and caps, provide the vial volume, neck type, dimensions, glass type, cap size, septum material and autosampler model. For tubing and ferrules, provide material, outside diameter, inside diameter, connection type and pressure requirement. For lamps or instrument parts, the instrument make, model and existing part number are essential.
Application-aware selection
Consider solvent compatibility, extractables, temperature, pressure, light sensitivity, sample volume, adsorption risk and detector sensitivity. Pre-slit septa may reduce needle stress but can influence sealing. Low-volume inserts can improve sample recovery but must match the vial and autosampler geometry. The correct choice is method-specific.
Support for repeat procurement
Once a compatible product is established, maintaining the manufacturer and catalogue number in procurement records reduces future ambiguity. Lotus Corporation supports product-code matching, alternate review, quotation, order coordination and available manufacturer documentation for supplied products.
Frequently Asked Questions
What details are needed to quote an HPLC vial?
Send vial capacity, dimensions, neck type, glass type, cap or septum requirement, autosampler model, current code and quantity.
Can you match an instrument manufacturer's part number?
Yes. Provide the complete make, model and part number. Compatibility must be confirmed before substitution.
Do you supply chromatography columns?
Column requirements can be reviewed using technique, dimensions, stationary phase, particle size, pore size, current column code and method.
Can you suggest a lower-cost equivalent?
Possible alternatives can be reviewed, but dimensional, material and method compatibility must be confirmed rather than assumed from appearance.
