Granulate Flow Tester GT Series (GTL, GT, GTB)
Brand: Erweka | Category: Scientific & Laboratory Equipment
Erweka's granulate flow tester family determines the flow behaviour of powders and granules by several measurement methods. The GTL is the entry level device for USP / EP compliant measurement of flowability by weight and by volume, operated through a simple numeric keypad and LC display with printable results. The GT adds a scale so stable weight can be measured during the flow, and on top of the GTL's two methods it measures flowability over a set time and the flow angle with graphical display. The GTB extends the GT with advanced automatic laser measurement of the angle of repose. Accessories such as outlet nozzles of differing diameters, smaller collecting funnels and an optional four stage agitator for poorly flowing samples allow customer specific measurements that are not EP compliant.

More from Laboratory Instruments
- Manual Powder & Granule Density Tester SMG 697
The SMG 697 is a manual powder and granule density tester for reproducible determination of apparent bulk density, usable with all free flowing powders and granulates. Following DIN ISO 697, apparent bulk density is found by measuring the mass of a powder in a container of known size after filling from a funnel of specific shape under defined conditions. Erweka supply the device with operating instructions and a calibration certificate.
- Friability Tester TAR II
The TAR II is Erweka's upgradeable USP / EP / JP friability and abrasion tester. Its high resolution 7 inch touch display puts the operator's attention on compliant friability testing, with TestAssist automatic calculation guiding the process step by step and an advanced balance connection transferring and calculating data directly. TestAssist offers three testing modes covering revolutions, time and USP test, checking that every parameter is set correctly, and in USP mode it calculates results automatically and triggers repetition of the test where USP guidelines require it. The unit can be configured with one or two test stations plus an optional smart scale, and all of it can be retrofitted later. A stand for the 10 degree position required by USP / EP is included.
- Tapped Density Tester SVM II
The SVM II is Erweka's latest generation tapped density tester. Its 7 inch high resolution touch display keeps the operator focused on 100 % USP / EP compliant tapped density testing, and TestAssist automatic calculation walks the user through the process while working out the Hausner Ratio and compressibility index and printing a report after every test. A newly designed SwitchPlate system produces five versions of the instrument, covering USP 1, USP 2 or USP 3 in one or two test station configurations or a combination of both methods, and the user can change from one variant to another within minutes. Supported methods run from USP 1 and USP 2 through to ASTM B527-15 and DIN EN ISO 787-11:1995.
