TLC Plates 120/box Aluminum Backed Silica Gel 60 F254 2.5cm x 6.5cm Precut Size AAdvance Instruments

Lab Thin Layer Chromatography TLC Plates

Buy on Amazon Find on eBay

Classic TLC silica plates, GF254 (Silica gel with gypsum as binding agent, fluorescence background at 254nm), 60 angstroms pore size. Aluminum backed-easily cut by a pair of scissors.

Precut size of 2.5cm by 6.5cm, 120 plates/box. With precut strips at a highly affordable price, save precious research time and labor, and focus more on the cutting-edge aspects of your research.

What's ideal is that these plates have neutral silica (pH 6-7) instead of the more common acidic silica (pH=5) for TLC silica plates.

The neutral silica make the plates compatible with running cpds. with an amino group even without adding triethylamine. At the same time non-amino cpds. behave the same as on acidic TLC plates.

Actual examples performed with the plates have been uploaded for users to see. In listing photo 5, highly similar diethyl maleate and dimethyl maleate are spotted on the plates and eluted with different ratios of ethyl acetate : hexanes, showing a gradual change of Rf.

Classic Glass Preparative TLC PLC Plates Silica Gel 60 F254 1 or 2 mm Layer Thickness (1000 or 2000 μm/microns) 20 x 20 cm Size 8 or 6 Plates/Box AAdvance Instruments (1 mm, 8)

Lab Thin Layer Chromatography TLC Plates

Buy on Amazon Find on eBay

Classic Preparative TLC Plates. Silica Gel 60 F254 type. 20x20cm plate size, 1mm (1000μm) silica layer thickness. pH 6.2-6.8, particle size 10-40 μm, pore size 60 Å. 8 plates per box. Glass backed.

A test run separating dimethyl maleate and dimethyl fumerate has been performed and shown in photos.

50mg of each compound (total mass 100mg), dissolved in a small amount mixture of hexane, acetone and dichloromethane was spotted onto the plate. The plate was eluted twice with hexane:acetone=15:1, giving a very good separation. While this is expected, this also indicated that depending on how far away each component band is on TLC, one can load material amounts of 100mg and more onto the plate since in the example the plates have not quite reached full capacity.

The preparative TLC method is an alternative to preparative HPLC. HPLC methods can be more expensive and when handled improperly, contamination can occur. Prep TLC is especially suitable for applications when there is relatively a small amount of sample, and purity requirements are high, and when at the same time the researcher is looking for a quick, convenient and economic way of purification.

Extra Thin Glass Capillary Tubes/Micro Pipettes TLC Spotting 0.2-0.25mm ID x 100mm 500 or 1500/pk (1500)

Capillary Lab Tubes

Buy on Amazon Find on eBay

Extra thin 1500 per pack capillary tubes, 0.2-0.25 mm inner diameter, 0.3-0.35 mm outer diameter, 100mm length. Non-calibrated, non precision tubes. Both ends open.

The extra thin diameter of these tubes makes it especially suitable for spotting aluminum or plastic backed type of TLC plates that usually have thinner silica coating than glass plates. Compared to thicker tubes, it avoids the spot from getting too large. It also saves your effort of splitting one draw-volume into spotting several times, needing to blow-dry or air-dry in between.

With a large quantity of 1500 tubes, at a highly affordable price (only $1.67/100 tubes), one can say goodbye to reusing capillary tubes in TLC spotting (or any other application), other than perhaps using both ends once each. Save the time, effort, washing solvent and risk of contamination, and focus on more important aspects of your research!

Convenient packaging with 1.5mm diameter hole on cap for easy tube drawing without need to open the cap or keeping it open all the time.

As shown in photos, approximate spotting volume as tested for water is 65mm x (0.12mm)² x 3.14 = 3µL. Testing method used is having the tube at a straight up angle and allowing the liquid to keep on climbing until it stops. If spotted at a tilted angle the draw volume can be larger, if reducing the spotting time the volume will be smaller. Most organic solvents will climb up to a lesser height, and have a smaller draw volume than water. On average about half the amount.

Glass TLC Plate Cutter up to 20cm Wide Thin Layer Chromatography General Glass Cutter w/Spare Blade AAdvance Instruments

Buy on Amazon Find on eBay

You may cut glass plates of up to 20 cm wide, and of any length.

The white measuring plate can be removed, if your TLC plate happens to be too thick to fit (usually when cutting preparative TLC plates).

The side screw fixed onto a turning-knob is for controlling the stop position of the scribbler, so that one can prevent the scribbler from cutting off of the glass plate and chipping off a small piece.

Usually, start from the far side relative to the screw, and cut towards the screw.

The cutter head can be replaced once it has become worn, which an extra spare is included in your purchase. More are available from us.

You do not need to transfer from a large container to a secondary container. Easily twist open to uncap and squeeze out the silica directly into your column or final apparatus.

You do not need any tools or spatulas, while the SiliDispense(TM) bottles will fit in most lab spatulas if for any reason a spatula is to be used. Bottle size designed for benchtop storage and direct use.
