MISCO Palm Abbe PA203x Digital Clinical Refractometer – Human Blood Total Protein, Plasma Screening & Density

MISCO Palm Abbe PA203x Digital Clinical Refractometer – Human Blood Total Protein, Plasma Screening & Density Digital Refractometer for Plasma Total Protein Measurement and Clinical Laboratory Applications The MISCO Palm Abbe PA203x-108-109-110-111 Digital Clinical Refractometer is a handheld digital measurement instrument configured with four human blood scales, including a dedicated total protein scale that reports results in grams per deciliter (g/dL). Keep compliant with California's AB2009 with this Refractometer. Designed around specialized measurement requirements, the PA203x provides readings for total protein, total solids, specific gravity, and density. Its total protein scale is relevant to plasma collection facilities and laboratories evaluating refractometry for protein measurement and donor-screening workflows. MISCO identifies serum total protein measurement as an established clinical application for refractometry. Its blood refractometer application resources provide the four measurement scales and their specifications listed below. Key Features Dedicated total protein scale: Displays human blood total protein from 1 to 14 g/dL. Four programmed measurement scales: Total protein, total solids, specific gravity, and density. Digital numerical results: Simplifies reading and recording compared with visually interpreted analog scales. Fine measurement resolution: 0.1 g/dL for total protein and 0.0001 for specific gravity and density. Handheld format: Suitable for convenient measurement workflows in laboratories and collection facilities. Multiple potential laboratory applications: Useful for facilities assessing plasma protein testing and related refractometry methods, subject to validated use. Technical Specifications: PA203x-108-109-110-111 Specification Details Manufacturer MISCO Product family Palm Abbe Model PA203x Instrument type Digital clinical refractometer Primary measurement application Human blood total protein Number of programmed scales 4 Displayed protein unit g/dL Instrument format Handheld Measurement Scales Scale 108 — Blood (Human) Protein Parameter Specification Measurement Total Protein (TPr) Range 1–14 g/dL Resolution 0.1 g/dL Stated precision 0.1 g/dL Scale number 108 The dedicated protein scale displays results directly in g/dL, the unit used for plasma total protein screening. The 6.0–9.0 g/dL interval is relevant to U.S. source plasma donor eligibility requirements; facilities must follow applicable regulations and validated operating procedures when evaluating donors.

Clinical laboratory testing: Serum and plasma total protein assessment where refractometry is appropriate to the validated method. Hospital pharmacy monitoring: Potential comparison of injectable medication samples against drug-specific reference readings when supported by a suitable scale and validated procedure. The included blood scales are not drug-specific. Veterinary laboratory workflows: Related protein and blood measurements may be of interest, although species-specific scales should be selected when required. Laboratory quality control: Comparative testing, repeatability assessments, and evaluation against reference methods under appropriate laboratory procedures. Measurement and Quality Considerations Accurate refractometry depends on proper sample preparation, instrument standardization, temperature conditions, cleaning, and quality-control procedures. Refractive index can be influenced by dissolved substances other than the analyte of interest, so a protein-scale result should not automatically be treated as a selective measurement of protein independent of other sample constituents. Facilities using the instrument for donor eligibility decisions should verify its intended use, validated performance, and applicable regulatory requirements before deployment. Frequently Asked Questions What does the MISCO PA203x measure? It provides four human blood measurement scales: total protein, total solids, specific gravity, and density. What is the total protein range? Scale 108 measures from 1 to 14 g/dL, with a stated resolution and precision of 0.1 g/dL. Can it be considered for plasma donor screening? Its dedicated human blood total protein scale is relevant to this application. Suitability for donor eligibility decisions must be confirmed against the manufacturer's intended use, validated performance, and applicable collection-facility requirements. Can it detect drugs or narcotics? Not as a general drug-screening test. Refractometry can support controlled comparison of certain fluid samples against established reference values, but the four included blood scales do not identify specific drugs or establish the presence of illicit substances. Is this the correct refractometer for veterinary applications? It may be relevant to related measurement work, but veterinary applications often require species-specific protein or urine scales. Confirm the required configuration before purchasing.
