Liquid Chromatography Digital System
Product Code : LSK-TWL-10806
Liquid Chromatography Digital System (SKU LSK-TWL-10806) is a high-performance liquid chromatography (HPLC) instrument for separating and quantifying compounds in solution. It combines gradient pumping, vacuum degassing, a temperature-controlled column compartment and a choice of UV/Vis, photodiode array or refractive index detection. Analytical chemistry, pharmacy and process engineering labs use it. Science Lab Supplies supplies it from Ambala, India to universities, research laboratories, training institutes, tender contractors and distributors.
Specifications
Every technical detail is listed in the table below. In short, it pairs a quaternary low-pressure or binary high-pressure gradient pump with a four-channel vacuum degasser, a column compartment controlled from 4 to 90 °C, and a choice of UV/Vis, 1024-channel PDA or RI detection.

Applications and Experiments for the Liquid Chromatography System
The system is used to separate, identify and quantify components of liquid samples, from drug assays and impurity profiles to sugars, organic acids and reaction products. It supports instrumental analysis practicals in chemistry and pharmacy degrees and analytical work in engineering and biotechnology research laboratories.
- M.Sc./B.Sc. chemistry: instrumental analysis with isocratic and gradient elution, with solvents filtered on the Equipment for Vacuum Filtration.
- B.Pharm/M.Pharm pharmaceutical analysis: assay and related-substance methods, with buffer pH set on a Bench Digital pH Meter.
- Biotechnology and chemical engineering: sugars and reaction products by RI or UV detection.
Standard Scope of Supply
The specification covers the quaternary or binary pump, the four-channel vacuum degasser, the column compartment and the UV/Vis, PDA and RI detector options; your chosen configuration is itemised on the quotation. Columns, solvents, standards and a computer are not listed and are quoted separately if required.
Packing, MOQ and Lead Time
Ask for a quotation for one system in the pump and detector configuration you need, or for several for a teaching lab. Each Science Lab Supplies quotation states the packing, delivery time and price, which helps when comparing test and measurement instruments in India.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines. Contact us through the contact page or the enquiry cart, and see the lab tender page for tenders.
Frequently Asked Questions
Which detectors are available for the Liquid Chromatography Digital System?
The specification lists a dual-wavelength UV/Vis detector (190–900 nm), a 1024-channel photodiode array detector (190–950 nm) and a refractive index detector for compounds without UV absorbance, such as sugars.
Does the system need special handling?
HPLC work uses organic solvents such as methanol, which are flammable and toxic. Handle them under supervision in a ventilated area and dispose of solvent waste under your institution's rules.
Who supplies the Liquid Chromatography Digital System?
Science Lab Supplies supplies it from Ambala, India, and quotes it with the pump and detector configuration you select for your laboratory or research group.
Are columns and solvents included?
They are not listed in the specification. Tell us the columns, solvents or standards you need through the contact page and they can be added to the same quotation.
