三泵独立·智能触控

ZW-300S旗舰型微生物限度检测仪

Three Independent Pumps · Smart Touch Control — In-Depth Analysis of the ZW-300S Flagship Microbial Enumeration Test System

在制药行业的质量控制体系中，微生物限度检查是保障产品安全性的最后一道防线。对于大型制药企业的QC实验室而言，检测仪器不仅要满足《中国药典》的法规要求，更要适应GMP环境下对数据完整性、操作可追溯性、实验连续性的严苛标准。ZW-300S旗舰型微生物限度检测仪，以三泵独立控制、智能触屏操作、打印数据追踪、在线自动消毒四大核心创新，重新定义了制药QC实验室的微生物检测标准。

In the pharmaceutical industry's quality control system, microbial limit testing serves as the last line of defense for product safety. For QC laboratories in large pharmaceutical companies, testing instruments must not only comply with the Chinese Pharmacopoeia regulations but also meet the stringent GMP standards for data integrity, operational traceability, and experimental continuity. The ZW-300S flagship microbial enumeration test system redefines the standards for microbial testing in pharmaceutical QC laboratories through four core innovations: three-pump independent control, smart touchscreen operation, printed data traceability, and automatic online disinfection.

一、产品定位：为GMP环境而生的旗舰之选

｜Product Positioning: The Flagship Built for GMP Environments

ZW-300S并非一台普通的微生物限度检测仪。它的设计初衷，是解决大型制药企业QC实验室在实际操作中面临的三重挑战：

The ZW-300S is not an ordinary microbial limit test system. It was designed to address three major challenges faced by QC laboratories in large pharmaceutical companies:

挑战一：数据完整性要求｜Data Integrity Requirements

GMP规范要求QC数据具备可追溯性（ALCOA+原则）。传统检测仪仅能显示运行状态，缺乏对关键参数的记录能力，实验数据的完整性难以保障。

GMP regulations require QC data to be traceable (ALCOA+ principles). Conventional test instruments only display operating status without the ability to record key parameters, making data integrity difficult to ensure.

挑战二：多样品并行效率｜Multi-Sample Parallel Efficiency

在纯化水、注射用水的日常监测中，QC实验室往往需要同时处理多个取样点的样品。如果各滤杯无法独立控制，则操作灵活性大打折扣。

In routine monitoring of purified water and WFI, QC laboratories often need to process samples from multiple sampling points simultaneously. If individual filter cups cannot be independently controlled, operational flexibility is significantly compromised.

挑战三：管路消毒难题｜Tubing Disinfection Difficulties

微生物检测管路中极易残留微生物，传统消毒方式需要频繁拆卸管路，不仅耗时，还增加了污染风险。

Microbial testing tubing is highly susceptible to microbial retention. Traditional disinfection methods require frequent disassembly, which is not only time-consuming but also increases contamination risk.

ZW-300S正是针对这三大痛点，以旗舰级配置给出了系统性的解决方案。

The ZW-300S provides a systematic solution to these three pain points with flagship-level specifications.

二、核心技术创新解析

｜Core Technology Innovation Analysis

创新一：三台独立隔膜液泵，精准控制每一个滤杯

｜Three Independent Diaphragm Liquid Pumps — Precise Control of Each Filter Cup

这是ZW-300S最具辨识度的技术亮点。

This is the ZW-300S's most distinctive technical highlight.

传统三联检测仪通常采用单泵驱动三个滤杯，这意味着三个滤杯的抽排只能同步启停。而ZW-300S内置了三台完全独立运行的隔膜液泵，每个滤杯可以单独控制抽排的启动和停止。

Conventional triple-place test systems typically use a single pump to drive all three filter cups, meaning that filtration across all cups can only start and stop synchronously. The ZW-300S, however, is equipped withthree completely independent diaphragm liquid pumps, allowing each filter cup to be individually controlled for starting and stopping filtration.

这一设计的实际价值：

•灵活排程：不同样品的过滤时间可能差异很大。独立泵控制意味着操作人员可以在一个滤杯仍在过滤时，提前完成另一个滤杯的操作，无需等待全部完成。

•避免交叉影响：单泵驱动多滤杯时，一个滤杯的堵膜可能影响其他滤杯的过滤效率。独立泵彻底消除了这一问题。

•提高通量：在熟练操作下，三泵独立可实现近似流水线式的连续作业，实际通量显著提升。

Practical Value of This Design:

•Flexible scheduling: Different samples may require vastly different filtration times. Independent pump control means operators can complete operations on one filter cup while another is still filtering, without waiting for all to finish.

•Elimination of cross-interference: With a single pump driving multiple cups, membrane clogging in one cup can affect filtration efficiency in others. Independent pumps completely eliminate this issue.

•Increased throughput: Under skilled operation, three independent pumps enable a near-assembly-line continuous workflow, significantly boosting actual throughput.

创新二：打印功能，构建完整数据链条

｜Printing Function — Building a Complete Data Chain

ZW-300S内置打印模块，可在实验过程中或结束后实时打印当前操作的关键信息：

•样品名称

•环境温度与湿度

•抽排时间

The ZW-300S features a built-in printing module that canprint key information of the current operation in real time during or after the experiment:

•Sample name

•Ambient temperature and humidity

•Filtration time

这一功能在GMP环境下的价值不可小觑。它使得每一份过滤操作都留有纸质记录，与电子数据形成双重保障，满足数据完整性中"可追溯"的核心要求。对于审计和合规检查，打印记录是直接可呈现的证据。

This function is invaluable in GMP environments. It ensures that every filtration operation leaves a paper record, forming a dual safeguard alongside electronic data and satisfying the core "traceability" requirement of data integrity. For audits and compliance inspections, printed records serve as directly presentable evidence.

创新三：全自动在线消毒，告别繁琐拆卸

｜Fully Automatic Online Disinfection — No More Tedious Disassembly

ZW-300S内置全自动消毒功能。操作人员无需频繁拆卸管路，只需通过触屏启动消毒程序，即可对内部管路进行全面消毒。

The ZW-300S features afully automatic disinfection function. Operators do not need to frequently disassemble tubing — they simply initiate the disinfection program via the touchscreen to comprehensively disinfect the internal tubing.

优势总结｜Advantage Summary:

创新四：全彩液晶触摸屏，交互体验全面升级

｜Full-Color LCD Touchscreen — Comprehensive Interaction Upgrade

ZW-300S配备彩色液晶触摸屏，实时显示：

•当前时间

•运行参数（抽排时间、泵的工作状态）

•仪器整体工作状态

The ZW-300S is equipped with acolor LCD touchscreen that displays in real time:

•Current time

•Operating parameters (filtration time, pump working status)

•Overall instrument working status

触屏操作相比传统按键，不仅信息呈现更丰富，操作逻辑也更直观。配合过滤定时功能与自动记忆，实验人员可以预设过滤时间，仪器自动执行并记录，减少人为干预。

Touchscreen operation, compared to traditional push-buttons, not only presents richer information but also offers more intuitive operational logic. Combined with the filtration timer function and automatic memory, laboratory personnel can preset filtration times, and the instrument will automatically execute and record, reducing human intervention.

三、制药QC应用场景

｜Pharmaceutical QC Application Scenarios

场景一：纯化水与注射用水的日常监测

｜ Routine Monitoring of Purified Water and WFI

制药企业的水系统是微生物污染的高风险环节。根据《中国药典》规定，纯化水和注射用水需定期进行微生物限度检查。

Pharmaceutical water systems represent a high-risk area for microbial contamination. According to the Chinese Pharmacopoeia, purified water and WFI require regular microbial limit testing.

ZW-300S的三泵独立设计在此场景下的优势尤为突出：QC人员可以同时处理来自不同取样点（如储罐、总送水口、总回水口、各使用点）的水样，每个滤杯独立控制，互不干扰。打印功能则确保每个取样点的检测数据均有迹可查。

The ZW-300S's three-pump independent design is particularly advantageous in this scenario: QC personnel can simultaneously process water samples from different sampling points (e.g., storage tank, main supply outlet, main return outlet, various use points), with each filter cup independently controlled without interference. The printing function ensures that testing data for each sampling point is traceable.

场景二：原辅料与成品的微生物限度检查

｜Microbial Limit Testing of Raw Materials and Finished Products

对于非无菌制剂的原辅料和成品，微生物限度检查是放行检测的必检项目。ZW-300S支持搭配多种泵头，可根据不同样品特性选择最适配的过滤方案。12种泵头的快速更换能力，使其能够灵活应对粉体、液体、黏稠样品等多种供试品的过滤需求。

For raw materials, excipients, and finished products of non-sterile preparations, microbial limit testing is a mandatory release test. The ZW-300S supports various pump head configurations, allowing selection of the most suitable filtration scheme for different sample characteristics. The quick-change capability of 12 pump head types enables flexible handling of powders, liquids, viscous samples, and other test article types.

场景三：实验连续操作——泵头免火焰灭菌

｜Continuous Experimental Operation — No Flame Sterilization of Pump Heads

ZW-300S可选配内置恒温培养箱。这一配置带来一个重要优势：泵头无需火焰灭菌，即可实现实验的连续操作。

The ZW-300S can be optionally configured with a built-in constant-temperature incubator. This configuration brings an important advantage:pump heads require no flame sterilization, enabling continuous experimental operation.

在传统操作中，每完成一个样品的过滤后，需要用酒精灯对泵头进行火焰灭菌，这不仅增加了操作步骤，还带来了安全隐患。而配备恒温培养箱后，取出的滤膜可以直接贴附培养基并放入培养箱，泵头无需火焰处理，真正实现了实验流程的无缝衔接。

In conventional operations, after completing filtration of each sample, the pump head must be flame-sterilized with an alcohol lamp, adding operational steps and safety risks. With the incubator configuration, retrieved membranes can be directly placed on culture medium and loaded into the incubator, with pump heads requiring no flame treatment, truly achieving seamless experimental workflow.
