$ 2,382.00 USD

Free Flow Water Sampler 5 l: High-Precision Oceanographic Sampling

An innovative, free-flushing sampler designed for optimal water exchange and high-fidelity sampling in oceanographic and limnological research.

The Free Flow Water Sampler 5 l is a premier instrument for researchers who require pristine, uncontaminated water samples from specific depths. Its innovative design eliminates the common limitations of traditional PWS or Niskin bottles by providing a completely unobstructed flow path. Unlike standard samplers that use cones or ball valves, this free-flushing construction ensures that nothing interferes with the water exchange inside the tube during descent, allowing for a more accurate representation of the water column.

Constructed from high-quality PVC and POM plastic to prevent metal contamination, the sampler consists of a durable tube with two lids connected by latex rubber tubing. It is highly versatile and can be used as a single instrument on a hydrographic wire, in a series for multiple depth sampling, or integrated into Multi Water Sampler, Rosette, or Carousel arrays. When deployed individually, it utilizes a mechanical messenger system for precise closure at the target depth, ensuring that the captured sample remains isolated from other layers of the water column.

Key Features

• Free-Flushing Construction: Innovative design without internal obstructions, ensuring perfect water exchange during descent.
• High-Resistance Materials: All-plastic design (PVC and POM) to prevent sample contamination and resist marine corrosion.

Incubadora ICES Hydro-Bios

$ 5,035.00 USD

Estándar ICES para mediciones de producción primaria de fitoplancton.

Uno de los procesos marinos más importantes es la formación de materia orgánica resultante de la interacción del dióxido de carbono, el agua y la luz solar, proceso conocido como fotosíntesis. La capacidad de medir este proceso es de gran importancia al evaluar los sistemas pelágicos marinos. En la práctica, la mejor manera de medir la fotosíntesis es observar la absorción de dióxido de carbono. La alta sensibilidad de las mediciones de absorción de dióxido de carbono permite utilizar este método en todas las circunstancias. Ni las concentraciones de algas bajas o muy altas ni las condiciones de poca luz y las bajas temperaturas son restricciones para este método.

Basado en el método 14C, utilizando la absorción del isótopo de carbono 14C radiactivo (Steemann-Nielsen, 1952), la incubadora ICES es el estándar ICES para las mediciones de producción primaria de fitoplancton. La incubadora que se muestra aquí se ha desarrollado principalmente con fines de monitoreo . Debe usarse preferentemente para muestras de agua tomadas de una capa de agua mezclada con una temperatura fija. Las mediciones de la cantidad de fitoplancton (basadas en las mediciones de concentración de clorofila-a) deben llevarse a cabo con fines de interpretación.

La incubadora ICES consiste en un tanque de plexiglás transparente iluminado que incorpora una rueda giratoria en la que se pueden sujetar 12 botellas experimentales. El depósito se llena de agua que se pone en movimiento mediante una bomba de circulación regulable. Así, la rueda giratoria se pone en rotación a velocidades de hasta 10 rpm con las botellas experimentales actuando como paletas. Las conexiones del tanque para una segunda circulación de agua permiten ajustes de temperatura del agua mediante el uso de equipos de templado externos.

Las 12 botellas experimentales de 50 ml de capacidad cada una tienen diferentes recubrimientos ópticos, de modo que cada botella tiene tasas de transmisión individuales y, por lo tanto, genera un número de 12 niveles de irradiancia (o intensidad de luz) diferentes. La unidad de iluminación está equipada con 10 tubos fluorescentes con un espectro de onda de acuerdo con las especificaciones ICES, cada uno puede encenderse individualmente. Para niveles de irradiación más altos, se puede montar una segunda unidad de iluminación en la placa de tierra de la incubadora ICES.

Las cámaras de plancton tubular se utilizan para el análisis microscópico de muestras de plancton. El proceso de sedimentación se lleva a cabo dentro del cilindro de inspección original para evitar cualquier falsificación de las muestras durante la manipulación. La cámara consta de un tubo de plexiglás con un anillo base de metal desenroscable que sostiene una placa base delgada de solo 0,2 mm. El análisis de la muestra se realiza en microscopios invertidos. Nuestro volumen de suministro incluye una cámara, una placa de cubierta de vidrio y un juego de 50 placas base de vidrio.
