Dosage syringes

A fully automated, personal computer-controlled spotter (e.g., the Camag Automatic TLC Sampler III), which consists of a stainless steel capillary connected to a dosage syringe operated by a stepper motor, can sequentially apply constant or variable volume samples, chosen from a rack of vials, within the range of 10 nl to 50 pi as spots or bands. 

The Linomat-5 is the latest development in a long line of CAMAG sample applicators, using the spray-on technique in qualitative, quantitative, and preparative TLC/ HPTLC (Fig. 5). This applicator sprays samples, preferably in the form of bands of selectable length or as spots. The spray-on technique enables larger sample volumes to be applied to the layer by contact transfer. The sample dosage syringe is selectable, 100 or 500 pL. 

Several systems for dosage syringes are commercially available (Oral-dose, Rectal dose, Baxa and Dose-pac Fig. 24.12). 

Before dispensing a prefilled syringe from the pharmacy it should be provided with a secondary container. A suitable container is a plastic box or a special plastic case of which the length can be adapted to the length of the (pulled out) dosage syringe.
