Classic TLC silica plates, GF254 (Silica gel with gypsum as binding agent, fluorescence background at 254nm), 60 angstroms pore size. Plastic 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.

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.

500 per pack capillary tubes, 0.5 mm inner diameter, 0.75 mm outer diameter, 100mm length. Made of borosilicate glass

As shown in photos, approximate spotting volume as tested for dichloromethane is 15mm x (0.25mm)² x 3.14 = 3µL, for acetone is 25mm x (0.25mm)² x 3.14 = 5µL, and for water is 45mm x (0.25mm)² x 3.14 = 9µL.

Testing method used is placing the tube at a straight up angle with only the tip submerged in the liquid and allowing the liquid to keep on climbing until it stops.

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.

254 nm UVC G4T5 4W UV bulb by Sankyo Denki.

6” (15cm) length including pins, 5.3” (13.5cm) excluding pins. 5/8" diameter. G5 base (pin distance 5mm).

【2 Adjustable Wands】Included a retractable brass wand and a durable polyethylene rod which the brass wand can be adjusted between 25-40 inches to help spray more spaces or hard-to-reach places!

【Lock Switch】The switch lock functions provide a comfortable grip and the lockable trigger helps prevent hand fatigue for better comfort.

【Super Wide Opening Design】Designed with a wide mouth opening which is convenient and easy to pour the water into the bottle. The high density filter can effectively prevent big debris and dirt from entering the water tank, which protects internal components from damage and prolongs service life.

Chromatography test paper for separating mixtures into their components

Paper strip is 6" long and 0.75" wide
