A Premier TLC Plate Vendor
Sorbtech is a premier TLC Plate vendor, offering the highest performance and widest selection of TLC plates on glass, plastic, and aluminum supports. We provide analytical and preparative layers with different sorbent coatings, including:

  • silica gel and alumina
  • Cellulose
  • Bonded phases
  • Polyamide, chiral, and more

plates are available in a variety of sizes from 20 x 20cm to 2.5 x 7.5cm with or without UV254 indicator and/or gypsum binder (11%).

Enhanced Quality Control
Our TLC plates are manufactured by stringent production control, including standardized lot tests, surface checks for roughness or cracks, as well as hardness and adherence checks.

Plates and sheets are immediately ready for chromatographic separation and require no coatings or impregnations. Sorbtech TLC layers are smooth, homogenous and well-adhering to produce reproducible quantitative evaluations.

Sizes Available: Many pre-cut sizes are available as shown in photo.

  • Analytical TLC Layer thickness: 50µm, 100µm, 150µm, 200µm, 250µm
  • Preparative TLC Layer thickness: 500µm, 1000µm, and 2000µm
  • Available with or without UV254 indicator.

Advantages and Disadvantages of Each Backing:
There are three supports used in TLC plates: glass, plastic, and aluminum. There are advantages and disadvantages to each, so it is important to consider these differences when determining what backing is appropriate for your TLC needs.

Glass-Backed TLC Plates

  • Used most often in TLC is glass: its chemical resistance and is easy to handle the plate
  • Disadvantages include fragility, size, and weight (glass plates are about 1.3 mm thick)
  • Requires additional protective packaging material.

Plastic-Backed TLC Plates polyester sheets (about 0.2 mm thick)

  • Advantages include resistance to all common solvent
  • Requires less packing and storage space
  • Plastic backed TLC plates are easily cut with scissors into any required size
  • Spots can be cut and eluted
  • Charring techniques can be applied for silica coated plastic TLC plates
  • Requires charring at lower temperatures than on glass
  • Maximum temperature for plastic TLC plates is 160°C.

Aluminum-Backed TLC Plates

  • A thicker aluminum support (about 0.15 mm thick), these TLC plates are significantly more stable and easier to cut than glass or plastic backed TLC plate
  • Features an outstanding adherence, which allows cutting of the sheets to any size desired without disturbing the sorbent layer
  • We recommend these plates for eluents containing high concentrations of water
  • As with plastic backed TLC plates sheets, you can spray or dip glass and aluminum plates with purely aqueous visualization reagents without any significant damage to the layer.
  • Problems may occur with aluminum backed TLC plates when using eluents containing high concentrations of mineral acids or concentrated ammonia (reacts with aluminum).
  • To address the backing instability, we recommend using our glass or polyester TLC plates.
  • Aluminum backed TLC plates offer the same advantages as the plastic backed plates with increased temperature resistance (e.g. for charring techniques).

Thin layer chromatography, TLC Plates

Like plastic backed TLC plates sheets, glass and aluminum TLC plates can be sprayed or dipped with purely aqueous visualization reagents without any significant damage to the layer. With aluminum backed TLC plates, problems might arise when using eluents containing high concentrations of mineral acids or concentrated ammonia (reacts with aluminum). As a solution to the issue of backing instability, we recommend using our glass or polyester TLC plates. Aluminum backed TLC plates offer the same advantages as the plastic backed TLC plates with increased temperature resistance (e.g. for charring techniques).
