ZT40 The ERWEKA Disintegration Tester ZT 40 Series provides the basic system for determination of the disintegration time according to USR ER DAB and BP requirements. It is ideally suited for the medium size laboratory where, nevertheless budgetary considerations are important. Similar in construction to the ZT 20 Series, the ZT 40 Series comprises of a central housing which serves to support the motor drive unit, basket rack assembly, beaker, removable perspex tank and immersion thermostat. Depending on the number of test stations chosen, the ZT 40 Series has the capacity of testing up to one, two, three or four different tablet samples simultaneously. Disintegration Tester Type ZT 43 (with three simultaneously driven test stations). As in the ZT 20 series, motive power is provided by a single drive-unit thus each of the test stations operate simultaneously. Similarly, the basket rack assembly or assemblies must be removed manually from the beaker and then locked into the loading/inspection position. The test run is started by lowering the basket(s) into the test media. In the case of the ZT 42, ZT 43 and ZT 44, the baskets are mounted in a single line of 2, 3 or 4. As in all the ZT Series, the temperature of the warming solution is controlled by means of a proportionally regulated circulation thermostat having a temperature range of 22-50 C (with an accuracy of ± 0.5 C) and a power consumption of 1500 watts at 230 V (1000 watts at 115V). The temperature in the water bath may be monitored by means of a glass thermometer provided with the instrument for this purpose.

The ERWEKA Disintegration Tester Series ZT 60 provides for the fully automatic disintegration testing of tablets, oblongs and coated tablets. The series is available with one test station (ZT 61), two test stations (ZT 62), three test stations (ZT 63) and four test stations (ZT 64). ZT60 This series provides the option of operating test stations either simultaneously or independently. The specially designed electronic measuring head comes complete with a modified basket rack assembly and six guided discs with photo sensitive detectors which monitor when the individual samples have disintegrated by determining the time when each individual guided disc touches the sieve mesh, that is to say, when the tablet has disintegrated through the sieve mesh. ft В С О _Е.F G H 1 J К I 0 fd О Р Q _,..Oj;:' Each electronic measuring head is fitted with six calibration adjustment knobs relating to each of the six separate tubes of the basket rack assembly. These are used for zeroing, or, in the case of dosage forms which generate tablet debris on disintegration, allow for the offsetting of the zero point. In the case of the latter, a special plate is positioned under the disintegration disc and the tester is then zeroed by this distance. Individual red lights (LED's) are illuminated when the disintegration discs touch the sieve mesh of the basket rack assembly. The disintegration time of each individual tablet is indicated on an LCD-display on the control panel as and when it occurs. As standard, the tester is supplied with modified timing facilities for use with sustained release products. In this instance, following the expiration of a preset time, the tester stops and the baskets are raised to allow the medium to be changed to a different ph-value. The test can then be restarted.

Sample print-out of test results and statistics in Stand-Alone operation when connected to a suitable printer. The Disintegration Tester ZT 60 Series are all provided with an alpha-numeric touch-sensitive keypad and special function keys to allow the operator to enter test identification parameters. A digital LCD-display with 320 digits (8 x 40) provides a visual check of the data entry and the ensuing display of programme parameters and test results. A password protected product memory allows the entry of up to 60 different product data files. These files contain the essential information on the product name, number, form, temperature of the water bath and minimum, nominal and maximum disintegration times of the product concerned and can be entered or recalled at will. Before starting a test run, the operator opens the product list contained in the sub menu "TEST", selects the appropriate product name and enters in the batch and machine number. The actual temperature in the water bath is measured by a calibratible PT 100 temperature sensor. This temperature is indicated on the LCD-display and recorded on the print-out of the test protocol.

The ERWEKA Disintegration Testers Series ZT 70 have been designed for the automatic determination and documentation of the disintegration time of tablets, oblongs, coated tablets according to the specifications as laid down in the USP, ER DAB and BR ZT70 The Series is available in four versions dependent on the number of test stations employed, namely from one to four (ZT 71, ZT 72, ZT 73 and ZT 74 respectively). The construction of the ZT 70 Series is identical to that of the ZT 60 with the exception of the method for determining the disintegration time. In case of the ZT 70, the disintegration time is determined by means of a magnet and inductive sensor. The method employs a specially modified disc which has an annular magnet in its centre. In all other respects, even weight, the disc is identical to that as specified in USP, ER DAB and BP such that its adherence to those Pharmacopoeia is not compromised. The modified basket rack assembly is fitted with a series of six inductive sensors located underneath the disintegration basket sieve mesh which detect the magnets embedded in the guided discs as they touch the sieve mesh indicating the disintegration time and hence the end of the test. These events are indicated by a series of six red LED's (representative of each tablet) mounted on the control panel of the tester. The sensitivity of the inductive sensors can be adjusted in increments of 0.1 mm between a distance of 0.0 and 0.5 mm in order to effectively off-set the zero point to allow for those forms containing tablet debris (film or coated tablets).
