A Laboratory Drying Rack is an essential piece of lab equipment used for drying glassware and other lab utensils after washing. It helps prevent contamination, water spots, and damage that can occur when drying items on ordinary surfaces.

Key Features:

• Serum-based testing for improved accuracy

• Fast results — easy to interpret within minutes

• High sensitivity and specificity for early detection

• Simple procedure suitable for clinics, laboratories, and healthcare facilities

• Single-use, hygienic, and individually packaged

• Easy to handle and dispose after use

✅ Key Features & Specifications

Measured parameters / Principle:

• Measures ions: Na⁺, K⁺, Cl⁻, iCa⁺⁺ (and sometimes Li⁺ or pH) using Ion-Selective Electrode (ISE) technology.

• Sample types: whole blood, serum, plasma, urine (and occasionally CSF).

Performance & workflow:

• Sample volume: approximately 90–100 µL.

• Analysis time: less than 60 seconds per sample.

• Throughput: up to 60 samples per hour.

• Calibration: automatic two-point calibration every 4, 8, or 12 hours (user-selectable) and optional one-point calibration per sample.

• Built-in quality control: includes tri-level QC, 30-day QC history, and Levey–Jennings (L-J) plots for QC trend monitoring.

Display & Interface:

• 5-inch colour LCD touchscreen (approx. 480 × 272 resolution).

• Built-in thermal printer (48 mm paper width, 42 characters).

• Interfaces: USB ports (for keyboard, mouse, barcode reader, or flash drive) and RS-232 serial port.

Physical & Environmental:

• Dimensions: around 365 × 255 × 375 mm (some variants 395 × 260 × 375 mm).

• Weight: roughly 5 – 7.5 kg depending on model.

• Operating conditions: 15 – 35 °C ambient temperature, ≤ 85 % relative humidity (non-condensing).

• Power: 100 – 240 VAC ± 10 %, 50/60 Hz.

Performance precision (typical):

• Coefficient of variation (CV %) — Na⁺, K⁺, Cl⁻ ≤ 2 %; iCa⁺⁺ ≤ 3 %.

Purpose

Electrophoresis is mainly used to:

Analyze DNA or RNA fragments

Study proteins and enzymes

Compare genetic samples

Check the purity or size of biomolecules

Principle of Operation

The machine works on the principle that charged particles move in an electric field:

Negatively charged molecules (like DNA) move toward the positive electrode (anode)

Smaller molecules move faster through a gel than larger ones

The gel acts as a molecular sieve

Main Components

Power Supply

Provides controlled voltage and current

Determines the speed of molecule movement

Electrophoresis Chamber (Tank)

Holds the gel and buffer solution

Contains electrodes at each end

Gel Medium

Commonly agarose (for DNA/RNA) or polyacrylamide (for proteins)

Has small pores that separate molecules by size

Buffer Solution

Conducts electricity

Maintains stable pH and temperature

Sample Wells

Small holes in the gel where samples are loaded

Electrodes

Create the electric field that drives molecule movement

Working Process

The gel is prepared and placed in the chamber

Samples are loaded into wells

Buffer is added to cover the gel

Power is switched on

Molecules migrate through the gel

Separated bands are visualized using stains or dyes
