Fully enclosed lighting

Antibacterial zone determination and potency analyzerAdopting a fully enclosed dark box to isolate the interference of ambient light and completely eliminate the phenomenon of light spots and halos caused by stray light refracted in the glass culture dish. Visible light uses 3-color LED to simulate natural light, and the upper light source has a 360 degree shadowless illumination function, providing *, stereoscopic, and clear imaging effects for antibacterial zone imaging.

One click determination of antibacterial zone

One click, accurately find the "boundary line" between the antibacterial transparent area and the underlying bacteria

Antibiotic potency determination

Provide one dose method, two dose method, and three dose method. The one dose method complies with the United States Pharmacopeia, while the two dose and three dose methods comply with the Chinese Pharmacopoeia 2015 edition.

Instrument detection accuracy

Repetitive self check: relative error ≤ 0.01%, relative error of repeated measurements ≤ 0.001mm

Uniformity self check: relative error ≤ 0.03%

Data Security and Management

Multi user login system, each account forms independent data, which is saved for a long time. The statistical results are output in PDF format and have audit tracking function.

Main performance indicators
Performance

1. Imaging device

Fully enclosed dark box, capable of eliminating stray light interference from the external environment

Tri color LED visible light

The brightness of the upper and lower light sources can be freely switched on and off, and a full touch adjustment button is used

Color temperature automatic control, close to natural light

Built in 254nm ultraviolet lamp, capable of sterilizing and disinfecting the cavity

16 million pixel ultra clear color camera

5-megapixel high-definition lens 8mm

2. Software functions

1) Classification one click measurement:

Automatic measurement: suitable for edge detection with clear edges and standard circular antibacterial circle contours

Quasi circle filling: Determine the center of the circle based on the arc and simulate the entire circle

Manual measurement: Click on three points on the circular arc of the antibacterial zone with the mouse to form a circle, suitable for antibacterial zones with blurred edges

2) Antibiotic potency determination:

One dose method potency testing: suitable for the United States Pharmacopeia

Two dose method potency testing: suitable for the Chinese Pharmacopoeia 2010 and 2015 editions

Triple dose method potency testing: suitable for Chinese Pharmacopoeia 2010 and 2015 editions

3) Instrument detection accuracy:

Repetitive self check: relative error ≤ 0.01%, relative error of repeated measurements ≤ 0.001mm

Uniformity self check: relative error ≤ 0.03%

Measurement difference between stations ≤ 0.1%

Relative error of repeated measurement of potency ≤ 0.2%

Relative error of potency measurement ≤ 0.2%

4) Auxiliary statistical tools:

Manual correction: Click the mouse to add or delete the outline of the antibacterial zone

Annotation: Text, numbers, and other information can be annotated on the image as needed

Custom calibration: Users can fine tune the calibration based on the height of the agar

Edge correction of antibacterial zone: After enlarging the image, correct the blurred edges of the antibacterial zone

5) Data Security and Management:

Multi user login system, each account forms independent data, and the data is saved for a long time

Automatically convert potency, report output in PDF format, original data cannot be changed

Equipped with audit tracking function, the software automatically records every step of operation by the operator, facilitating the traceability of subsequent result data

Compatible with CFR 21 Part 11: System Security, Operational Control, File Management
