Micropipettes are indispensable tools in modern laboratories, enabling precise liquid handling for applications in molecular biology, microbiology, biochemistry, and more. Among the various types available, fully autoclavable fixed-volume micropipettes stand out for their accuracy, durability, and ease of sterilization. This blog post explores the features, benefits, and technical specifications of fixed-volume micropipettes in the range of 5 µl to 1000 µl, with a focus on manufacturers and suppliers in Hyderabad, India. Whether you’re a researcher, lab manager, or procurement officer, this guide will help you make informed decisions about selecting the right micropipette for your needs.

What Are Fixed-Volume Micropipettes?

Fixed-volume micropipettes are designed to dispense a specific, pre-set volume of liquid with high precision. Unlike variable-volume micropipettes, which allow users to adjust the volume, fixed-volume models are calibrated for a single volume, minimizing the risk of user error during volume setting. This makes them ideal for repetitive tasks requiring consistent liquid dispensing, such as PCR preparation, ELISA assays, or analytical chemistry experiments.

Key Features of Fully Autoclavable Fixed-Volume Micropipettes

1. Autoclavability: Fully autoclavable micropipettes can be sterilized at 121°C for 20 minutes, ensuring contamination-free operation in sensitive applications like cell culture and molecular biology.
2. High Precision and Accuracy: Fixed-volume micropipettes are engineered for minimal inaccuracy and imprecision, ensuring reliable results.
3. Ergonomic Design: Lightweight construction and comfortable finger rests reduce hand fatigue during prolonged use.
4. Durability: Made from high-quality materials like polypropylene and stainless steel, these micropipettes withstand harsh laboratory conditions.
5. Universal Tip Compatibility: Most models feature a universal tip cone, compatible with a wide range of pipette tips.

Technical Specifications of Fixed-Volume Micropipettes (5 µl to 1000 µl)

The following table outlines the specifications for a range of fully autoclavable fixed-volume micropipettes, covering volumes from 5 µl to 1000 µl. These specifications highlight the inaccuracy and imprecision percentages, which are critical for assessing the reliability of a micropipette.

Model	Volume (µl)	Inaccuracy (%)	Imprecision (%)
SSPRIME-F5	5	±2.5	<1.5
SSPRIME-F10	10	±1.2	<0.8
SSPRIME-F20	20	±1.0	<0.4
SSPRIME-F25	25	±1.0	<0.4
SSPRIME-F50	50	±0.8	<0.3
SSPRIME-F100	100	±0.8	<0.3
SSPRIME-F200	200	±0.8	<0.3
SSPRIME-F250	250	±0.8	<0.3
SSPRIME-F500	500	±0.8	<0.3
SSPRIME-F1000	1000	±0.8	<0.3

Understanding Inaccuracy and Imprecision

• Inaccuracy (%): This measures the deviation of the dispensed volume from the set volume. For example, the SSPRIME-F5 (5 µl) has an inaccuracy of ±2.5%, meaning the actual dispensed volume could range from 4.875 µl to 5.125 µl.
• Imprecision (%): This indicates the reproducibility of the dispensed volume. Lower imprecision values, such as <0.3% for the SSPRIME-F100, ensure consistent results across multiple pipetting cycles.

These specifications make the SSPRIME series suitable for high-precision applications, with the 100 µl to 1000 µl models offering exceptional accuracy and reproducibility.

Why Choose Fully Autoclavable Fixed-Volume Micropipettes?

1. Contamination Control

In laboratories handling sensitive samples, such as DNA, RNA, or cell cultures, contamination can compromise results. Fully autoclavable micropipettes allow complete sterilization, eliminating microbial and chemical contaminants. This is particularly important in Hyderabad’s thriving biotechnology and pharmaceutical sectors, where cleanroom protocols are standard.

2. Cost-Effectiveness

Fixed-volume micropipettes are generally more affordable than variable-volume or electronic models. Their simple design reduces maintenance costs, and their durability ensures a long service life. For labs in Hyderabad operating on tight budgets, these micropipettes offer a reliable, cost-effective solution.

3. Precision for Repetitive Tasks

In applications like qPCR, where the same volume is dispensed repeatedly, fixed-volume micropipettes eliminate the need for volume adjustments, reducing errors and saving time. The SSPRIME-F100 (100 µl), for instance, is ideal for preparing standard solutions or loading samples into 96-well plates.

4. Ease of Calibration

Fixed-volume micropipettes are easier to calibrate than variable-volume models, as they are designed for a single volume. Many manufacturers in Hyderabad provide ISO 8655-compliant calibration certificates, ensuring traceability and compliance with international standards.
