Haloes Caliper

Haloes Caliper

Feature Introduction

Functional introduction

Adopting a fully enclosed dark box, * isolating the interference of ambient light, * eliminating the light spot and halo phenomenon formed by the refraction of stray light in the glass culture dish, providing good light and shadow conditions for colony counting.

colony counting

The adjustment function of colony display mode, including particle contour, particle number, and particle filling, can be set in color according to user needs.

One click statistics

10 mode one click counting

Rapid colony count:

Single color rapid statistics: Conduct rapid statistics on single color colonies, multi-color colonies, small colonies, large colonies, colored colonies, and spreading bacteria.

Multi color bacteria automatic stacking counting: By using a color pen to extract the color of the target colony, all colonies of the same color in the selected area can be automatically segmented. This algorithm is suitable for rapid statistics of colonies of specific colors.

Microbe statistics: adapted to the statistics of small bacterial colonies.

Mega bacteria statistics: rapid statistics of large bacterial colonies within a region, with a focus on large bacterial colony statistics.

Statistics of bacteria resembling the background color: When the bacterial colonies in the area are similar in color to the background color of the culture dish, statistics of bacteria resembling the background color are used.

Adhesive bacteria statistics: suitable for rapid statistics of colonies with a single background color, no color, and blurry edges.

Scattered bacteria statistics: Quickly count colonies with clear edges and scattered patterns.

Grid filter membrane: including 3M paper colony statistics, filter membrane paper colony statistics, and solid line paper colony statistics.

One click determination of antibacterial zone

Haloes Caliper One click,Accurately identify 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.

Data Security and Management

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

2) The statistical results are output in PDF format, and the original data cannot be changed

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

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

2)Antibacterial zone determination and potency analysis

Automatic measurement: suitable for clear edges and standard circular antibacterial circle contoursedge detection

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

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)Auxiliary statistical tools:

Manual correction: Click with the mouse to add or delete missing colonies

Intelligent correction: Based on one click statistics, intelligent correction can be performed

Measurement tools: angle, line segment, area, curve

Removal of contaminating bacteria (impurities): Remove impurities based on color, diameter, and roundness

Single colony morphology analysis: Clicking on a single colony can reveal information such as roundness, diameter, circumference, and area of the colony

All colony morphology: After statistics, the roundness, diameter, circumference, area, and other information of all colonies on the plate can be obtained

Colony size classification: After counting, display the colony size in 25 categories based on the contour size of each colony

Conversion of total number of bacterial colonies in the sample: Based on the actual diameter of the culture dish and the dilution of the sample, automatic conversion is achieved
