实验室平衡的用途
Lab balances and scales提供各种设计，以测量固体，液体和粉末的样品质量，密度和水分含量。虽然量表决定样品的质量，但平衡旨在比较多个样品的质量。余额和尺度有几种配置：分析，精度，上载，前负荷，高容量和水分分析。
实验室中使用了哪些类型的余额？
Certain balances offer additional functionality, such as data traceability (for 21CFR Part 11 compliance), integration with external devices (such as a printer, computer, or barcode reader), pipette calibration, and sample protection (such as a draft shield) for installation into a laminar flow hood or ISO-rated cleanroom.
A-余额类型

A1-分析平衡
分析平衡对于大多数标准实验室称重操作，例如密度确定，比较质量分析和动态称重是最佳的。分析余额测量样品至非常紧密的公差，可恢复到0.0001克。由于分析尺度对空气电流和温度变化很敏感，因此大多数模型都包含屏蔽率，以维持受控的测量环境。
A2 - Precision Balances
精确余额are an economical alternative to analytical balances. While precision scales support higher weight capacities than analytical models, they do not yield similar tolerances (readabilities down to 0.001 grams). Precision scales produce stable readings within environments experiencing temperature and humidity fluctuations.
A3 - High-Capacity Balances
High-capacity balancesare designed to weigh bulk powders, animals, and heavy storage containers in production environments. While analytical and precision balances accommodate weight loads of 300 grams and 600 grams respectively, high-capacity balances can measure loads up to 34,000 grams.
A4-微平衡
微balances旨在以行业领先的公差（降至0.0000001克）来称重少量样品（最多6克）。微生物对大气条件的变化极为敏感，需要半年度重新校准。
B - Scale and Balance Weighing Capacity
（返回图表）
Laboratory balances提供广泛的称重能力，从旨在向下测量到毫克和微克水平的超微小尺度，再到能够测量高达34,000克的权重的高容量平衡。电子尺度可提供数十个不同单元的读数，包括克，毫克，千克，磅，盎司和谷物。
C - Balance Weighing Pan Size
（返回图表）
Laboratory balances and scales include weighing pans to accommodate a variety of sample types, including powders, liquids, solids and living organisms. Smaller, round pans are optimal for weighing low quantities of aqueous samples or powders, while larger, square pans are ideal for weighing solids or tare vessels (such as weight buckets).
D - Balancing Loading and Format
（返回图表）
D1-前负载余额
Front-loading balances include draft shields to protect the sample from air movement and temperature fluctuations. Ionizer draft shields dissipate static charges to protect fine powders from aggregating to draft shield walls.
D2-载荷余额
Top-loading balances are designed without a draft shield to provide easy access to the weighing pan. Top-loading scales are optimal for weighing bulky solids, animals, or large containers that require unobstructed access to the weighing pan.

F1-平衡草稿盾牌
Sartorius Modular Cubis II Micro and Ultra-Micro Balancesare available with glass or stainless steel draft shields. Draft shields offer protection for fine powders or aqueous samples sensitive to air currents or static charges. Common draft shields provide access to the weighing pan from the front, top and sides.
F2 - LIMS Integration
Sartorius Quintixbalances offer data export programs compatible with a variety of software packages, including Microsoft Office and LIMS (Laboratory Information Management System), to support sample lot traceability, workflow efficiency, and event reporting.
F3 - Auto Calibration of Balances
Sartorius Securaand Quintix balances include isoCAL software to support automatic or user-determined instrument recalibration routines at monthly intervals or after balance relocation.
F4- USP合规性
Sartorius Cubis II（PDF），Quintix和Secura平衡自动记录所有记录的每日出口测量结果，并根据USP <797>和<800>指南进行审查。
F5 -21CFR第11部分合规性
Sartorius Cubis IIbalance includes end-to-end data integrity, safe data transfer, electronic signatures for controlled data access, and audit trailing for 21CFR Part 11 compliance.
