Reviewed in Mexico on September 14, 2023
El proveedor antes de enviar el instrumento, se puso en contacto por correo electrónico para confirmar el pedido y dar especificaciones, quedando abiertos a cualquier duda que existiera. Es importante responder al correo para confirmar. ¡Un excelente servicio al cliente!Llegó antes de tiempo, bien empacado y en buen estado.Lo que más me impresionó es su alta calidad y su bajo precio.El precio en México de su equivalente es de 4 a 5 veces más alto que el precio que me ofrecieron aquí. Ya lo he utilizado para hacer determinaciones analíticas y es muy adecuado para el trabajo de laboratorio. Tiene características de desempeño similares al clásico Spectronic 20 de Baush &Lomb a un costo francamente competitivo lo recomiendo ampliamente.
