Laboratory Products 27 Ultrafast fi bre laser enables supercontinuum generation
Chromacity Ltd reports that the outstanding coupling effi ciency and high stability of its Model 1040 ultrafast fi bre laser enable the generation of exceptionally broad and fl at supercontinua in the near-infrared region (750-1300 nm).
This compact and user-friendly laser provides an ideal solution for producing a cost-effective near-infrared supercontinuum by focusing ultrashort pulses into nonlinear materials, such as photonic crystal fi bres. Unlike solid-state lasers, which typically produce beams with an elliptical cross-section, the Model 1040 laser outputs from a single-mode fi bre, ensuring a perfectly symmetric beam that achieves coupling effi ciencies exceeding 75% into photonic crystal fi bres.
A technical note from Chromacity explores the implementation of supercontinuum generation in nonlinear fi bres as a cost-effective method for producing broadband near-infrared light. This light source is well-suited for applications such as spectroscopy, optical coherence tomography, and CARS spectroscopy/microscopy.

Optimised plating of bacterial and yeast cells on agar plates
AMSBIO’s EZ-Spread™ Plating Beads offer a faster, safer, and more effi cient way to plate bacterial and yeast cells on agar plates, eliminating the need for traditional glass rods and ethanol fl aming. This innovative solution streamlines the plating process, reducing the risk of contamination and enhancing lab productivity.
Manufactured with precision moulds, EZ-Spread Plating Beads are designed for uniform shape and diameter, ensuring even distribution of cells. This results in more consistent colony formation compared to conventional methods, making them ideal for high-throughput applications.
EZ-Spread Plating Beads are available in convenient dispenser bottles for 100 plates or single-use tubes for 50 plates. Supplied pre-sterilised and ready to use, they allow researchers to plate multiple samples simultaneously, improving workfl ow effi ciency. The pre-sterilised, ready-to-use packaging ensures a safe, straightforward experience.
EZ-Spread™ Plating Beads are an indispensable tool for modern laboratories looking to optimise cell plating while maintaining high safety standards.

ADVERTORIAL Maximising effi ciency in sample preparation with miVac
Sample evaporation and concentration are critical steps in many R&D workfl ows, but ineffi ciencies can slow processes and impact results. The miVac centrifugal evaporator/concentrator range, available from Biopharma Group in the UK and Ireland, is engineered to overcome these challenges with superior performance, reliability, and ease of use.
A key innovation in the miVac range is the SpeedTrap™ condenser, which effi ciently captures solvent vapours before they reach the pump. Unlike traditional bowl condensers that rely on glycol and multiple heat transfer layers, SpeedTrap™ ensures direct vapour contact with the cooling coil, improving condensation effi ciency. This design reduces maintenance, extends pump lifespan, and enhances solvent recovery, all while minimising environmental impact.
Another standout feature is the precisely controlled evaporation chamber. Unlike many competitors that offer broad temperature adjustments, the miVac allows for fi ne-tuned settings, ensuring optimal conditions for different solvents. The system also includes aluminium monoblock rotors - far superior to plastic alternatives in heat conduction - resulting in faster evaporation times and greater consistency.
To further refi ne performance, the miVac features a pressure regulator and ramp control, preventing solvent bumping and optimising vapour capture. For those working with aqueous samples, an optional freeze-drying kit expands its versatility, allowing small-scale lyophilisation alongside evaporation processes.
Compact, effi cient, and cost-effective, the miVac is an essential tool for labs looking to streamline evaporation and concentration workfl ows. Whether handling DNA, RNA, or complex solvent mixtures, the miVac delivers consistent, high- quality results.
Find out how miVac can enhance your lab’s productivity.
