CentriVap® Centrifugal Vacuum Concentrators & Cold Traps

CentriVap Vacuum Concentrators — Executive Summary

Significance of the topic

Laboratory centrifugal vacuum concentrators are essential tools for fast, reproducible removal of solvents from small-volume samples in life-science and analytical laboratories. They combine centrifugal force, controlled heating and regulated vacuum to accelerate evaporation while protecting heat- or oxidation-sensitive analytes (RNA, proteins, small molecules). Modern systems that integrate temperature control, cold trapping and appropriate vacuum pumping protect samples, instruments and personnel from corrosive or volatile vapors and enable high-throughput workflows used in genomics, drug discovery, QA/QC and analytical sample preparation.

Objectives and overview of the product family

This document summarizes Labconco’s CentriVap and RapidVap product lines and accessory ecosystem. The main goals of the product family are to: provide configurable concentrator systems for different sample types and volumes; accelerate evaporation safely and reproducibly; support corrosive or acid-containing workflows; and enable data capture and operational control for routine laboratory integration. Key product variants include CentriVap Pro (refrigerated, benchtop, DNA, acid-resistant), Standard CentriVap (including DNA version), and RapidVap evaporators, together with cold traps, vacuum pumps, rotors and system accessories.

Used instrumentation

The CentriVap ecosystem consists of the following instrument classes and notable specifications:

• CentriVap Pro series — 5" color touchscreen with VaporWorks OS, brushless motor (500–1800 RPM), chamber heater (300 W, optional additional 300 W Heat Boost), selectable chamber temperature control (ambient to 100 °C; refrigerated models also cool to -10 °C), stackable rotors up to 312 tubes or 6 microtiter plates.
• CentriVap Pro DNA — compact integrated unit with built-in diaphragm pump (achieves ~7 mBar; 38 L/min) and two 177 mL glass traps.
• Standard CentriVap and Standard DNA — microprocessor control, LCD programming (1–9 saved methods), rotor options for up to 148 samples, 300 W heater.
• Acid-Resistant variants — PTFE-coated aluminum chamber, Hastelloy shaft and glass lid options for safe handling of 0.1–1% acids and other corrosives.
• Cold Traps — models with collector temperatures of -50 °C, -84 °C and -105 °C; 4 L stainless steel collectors; acrylic or stainless lids; optional glass inserts and chemical trap canisters/inserts for acids, moisture, solvents, ammonia or radioisotopes.
• Vacuum pumps — diaphragm pumps (chemically resistant wetted parts: PTFE/fluoropolymers) for aqueous and volatile solvent use; two-stage oil-sealed rotary vane pumps with gas ballast for deeper vacuum (ultimate ~2 x 10^-3 mBar) and higher displacement (e.g., 117 L/min).
• Accessories — a wide range of rotors (metal, PTFE-coated, thermoplastic, microtiter plate and pear-shaped flask rotors), CentriZap strobe lights for in-run observation, carts, manifolds, secondary traps and tubing kits.

Methodology and recommended configuration workflow

Choosing the right configuration follows a four-step decision process:

1. Sample type: identify aqueous vs organic solvent, heat sensitivity, presence of acids or corrosives, and typical concentration ranges.
2. Sample volume: select concentrator (typical up to 50 mL) or evaporator (up to ~450 mL) and an appropriate rotor for tube/vial dimensions.
3. Cold trap selection: choose a trap temperature (-50, -84 or -105 °C) based on solvent freezing points and the need to protect downstream pumps and the environment. Include chemical trap inserts when handling corrosives or radiochemicals.
4. Vacuum pump selection: match required ultimate pressure and gas load. Use diaphragm pumps for corrosive or moisture-laden streams and rotary vane pumps where deeper vacuum and higher throughput are needed.

Key features, performance and discussion

Major strengths and operational details across the product line:

• VaporWorks OS: integrated touchscreen control, programmable methods, in-run parameter edits, data logging and CSV/PDF export. Ethernet and Wi-Fi enable remote alerts and software updates.
• Throughput and rotors: stackable rotor designs support high-density processing (up to 312 microtubes or 6 standard microtiter plates), enabling batch-driven laboratory workflows.
• Temperature control: refrigerated Pro models uniquely combine cooling to -10 °C with heating to +100 °C to handle heat-sensitive samples and allow more precise endpoint management.
• End point assist and Smart Dry: software features speed processing (air flush/Smart Dry) and provide guidance on dryness without overexposure to heat.
• Pump and trap protection: multi-stage glass traps in DNA models and external cold traps with optional chemical inserts minimize solvent migration to pumps and the lab atmosphere.
• Safety and reliability: rotor imbalance detection, lid safety sensors, automatic vacuum release (Quick-Stop), and optional acid-resistant materials improve operational safety and longevity.
• Environmental considerations: HCFC/CFC-free refrigeration and optional Eco-Cool refrigerant reduce GWP impact compared with legacy refrigerants.

Benefits and practical applications

Practical advantages for laboratory use:

• High-throughput evaporation with reproducible control of temperature, vacuum and centrifugal force improves consistency for analytical prep, PCR/DNA cleanup, sample concentration prior to LC-MS and small-scale lyophilization.
• Configurability allows labs to tailor systems for corrosive chemistry, volatile organic solvents, and temperature-sensitive biomolecules.
• Integrated data logging and network connectivity support traceability, method transfer and documentation needs in regulated environments.
• Accessories (cold traps, chemical inserts, rotors) permit safe expansion from routine sample concentration to specialist workflows such as radiochemistry or acid-based extractions.

Future trends and potential uses

Emerging directions and opportunities to enhance concentrator workflows:

• Greater automation and LIMS integration for scheduling, method management and electronic batch records will improve traceability in regulated labs.
• Improved solvent recovery and downstream recycling from cold traps could reduce waste and operating costs while supporting sustainability goals.
• Advanced sensors and predictive maintenance (via networked diagnostics) can further reduce downtime and extend pump/trap life.
• Development of lower-GWP refrigerants and more efficient compressor designs will continue to decrease environmental impact.
• Integration with in-line analytics (e.g., headspace monitoring or optical dryness sensors) could make endpoint detection more quantitative for critical applications.

Conclusion

Labconco’s CentriVap product family presents a comprehensive, modular approach to centrifugal vacuum concentration and evaporation for modern laboratories. The ecosystem—spanning refrigerated, DNA-focused, acid-resistant and standard benchtop models—addresses a wide range of volumes, chemistries and throughput demands. Key differentiators are the VaporWorks OS for method control and data capture, stackable high-capacity rotors, cold-trap options for solvent protection, and configurable pump choices to match vacuum depth requirements. When matched properly to sample type, cold trap and pump, CentriVap systems offer an effective, safe and scalable solution for routine concentration, sample preparation for instrumentation, and specialized desiccation or small-scale lyophilization tasks.
