ADAMANT, SIL G or SIL HD are silica layers on glass backing. It’s hard to imagine a laboratory without our reliable TLC and HPTLC glass plates.

ALUGRAM and POLYGRAM TLC/HPTLC sheets are easy to handle, lightweight and flexible. High performance silica on ALUGRAM Xtra sheets provides outstanding wettability for precise colourisation results. Moreover, these TLC sheets are easy to cut with scissors.

In addition to high quality TLC plates and sheets, we offer staining reagents and developing chambers, as well as introductory sets for educational purposes.

Glass plates are robust, heat proof and chemically resistant to all common mobile phases and visualisation reagents. They are the traditional option in TLC/HPTLC and are widely used in the pharmaceutical sector and other laboratory environments.

• Thickness (approx.): 1.3mm
• Weight and storage requirements: high
• Torsional strength: ideal
• Temperature stability: high
• Susceptible to breakage: yes
• Can be cut with scissors: no
• Chemical resistance against solvents: high
• Chemical resistance against mineral acids and concentrated ammonia: high
• Suitability for aqueous detection reagents: depends on phases (layer)

Aluminium sheets are easy to handle, lightweight and flexible. High performance silica on ALUGRAM Xtra sheets provides outstanding wettability for precise colourisation results, even with 100% aqueous detection reagents. Moreover, ALUGRAM Xtra sheets are easy to cut with scissors. No flaking of silica occurs.
